Bluetooth Wireless Barcode Scanners

Bluetooth Wireless Barcode scanners are fast gathering popularity in the retail and service related industries. Many companies have adopted using Bluetooth wireless barcode scanners and found them to be an integrated part of their business operations

Wireless barcode scanners using Bluetooth technology provided wireless coverage and lower cost per barcode scanner compared with wireless 802.11b barcode scanners.

Bluetooth wireless barcode scanners are light and portable thus allowing the operator to move easily from place to place.

It also makes it easy to scan huge, bulky and immoveable items as the operator can scan easily without moving the large items.

They are two types of barcode scanners available. One used CCD based technology, the other is laser-based technology. CCD-based barcode scanners uses optical cameras to capture barcode images and then translate that to barcode information. One major disadvantage of CCD barcode scanners is that the scanning distance is shorter. CCD barcode scanners is used mostly in fixed or static barcode scanners where distance is not a problem.

Laser barcode scanners uses a laser to capture barcode information. As such, they have a longer scanning distance and also can scan curved surface. Most Bluetooth wireless barcode scanners are laser-based.

The price of Bluetooth wireless barcode scanners have rapidly dropped over the years and nowadays you can get a pretty good one for a few hundred dollars. Therefore it is a good investment to get these for your business.

Bluetooth Security

These days, all communication technology faces the issue of privacy and identity theft, with Bluetooth being no exception. Almost everyone knows that email services and networks require security. What users of Bluetooth need to realize is that Bluetooth also requires security measures as well.

The good news for Bluetooth users is that the security scares, like most scares, are normally over dramatized and blown entirely out of proportion. The truth being told, these issues are easy to manage, with various measures already in place to provide security for Bluetooth technology.

It's true that there has been some Bluetooth phones that have been hacked into. Most devices that are hacked into are normally those that don't have any type of security at all.

According to Bluetooth specialists, in order to hack into a Bluetooth device, the hacker must: 1. Force two paired devices to break their connection. 2. Steal the packets that are used to resend the pin. 3. Decode the pin.

Of course, the hacker must also be within range of the device, and using very expensive developer type equipment. Most specialists recommend that you have a longer pin, with 8 digits being recommended.

Fundamentals of security The "pairing process" is one of the most basic levels of security for Bluetooth devices. Pairing, is two or more Bluetooth devices that recognize each other by the profiles they share - in most cases they both must enter the same pin.

The core specifications for Bluetooth use an encryption algorithm, which is completely and entirely secure. Once the devices pair with each other, they too become entirely secure.

Until they have successfully paired, the Bluetooth devices won't communicate with each other. Due to this pairing process and the fact that it is short range - Bluetooth technology is considered to be secure.

As the news has indicated, experienced hackers have developed ways to get around this level of basic security. There are ways to get around this threat, as you can install software to prevent hackers from getting in.

With Bluetooth becoming more and more popular, it's really no wonder that security is always in question. As Bluetooth gets bigger and better, security will always be something that no one really takes lightly.

If you've been concerned about Bluetooth security in the past, rest assured that newer devices will offer bigger and better security. Preventing hackers from getting in is something every owner is concerned about - and the manufacturer's are very aware.

The Bluetooth Solution

The technology of Bluetooth will take small area networking to the next level by removing the need for user intervention and help keep transmission power very low to preserve battery power. Each transmission signal to and from your cellular phone will use just 1 mw of power, giving you plenty of space on your battery to talk.

Bluetooth is a networking standard that will work on two levels: 1. It will provide agreement at the physical level, as Bluetooth is a radio frequency standard. 2. It will provide agreement at the level of protocol, where products will have to agree on when bits are sent, how many are sent, and how the parties in conversation can be sure the message recieved is the same one that was sent.

The major draws to Bluetooth is the fact that it's wireless, inexpensive, and automatic. There are other ways to get around wires, including infrared. Infrared uses light waves of a lower frequency than the human eye can, and is normally used in television remote controls.

The technology of Bluetooth is intended to get around the problems that normally come with infrared systems. The 1.0 older standard of Bluetooth has a max transfer speed of 1 MB a second, while the 2.0 Bluetooth standard can manage up to 3.0 MB a second. To make things better, 2.0 is compatible with 1.0 devices.

As a solution to wireless, Bluetooth will eliminate the need for messy cords, keeping everything nice and neat. It's perfect for those who like to talk on cell phones, as you no longer need to hold the phone next to your ear - which is great for those who travel a lot.

The Skipper on a charter yacht

The skipper is the heart of every floating vessel on earth. His word is (or should be) law to everybody on board. Yet, on a pleasant sailing holiday with your friends it can be deemed as unpleasant, and hard for the skipper, to order those friends to do something they may not like to do, and may consider unnecessary or a "dirty job". A crew member might think -"why me again, why not Charlie this time", not realising he may be the best person for the job, especially in difficult or tricky maneuvers. It is not always easy for skipper or crew member.

What about the situation where you have hired a professional skipper? You have to admit that the situation where your employee (the skipper) commands you to do something you may not like, is something which does not occur in other forms of business or social life !! But please bear in mind that you are paying this guy to do precisely this. If he doesn't, then he is not doing his job properly and you must remember that in extreme situations your life may depend on his decisions and commands, and the way you react to them.

There are three aspects regarding the skipper and I will analyse them for you:

a. You are the Skipper

You must discuss your position with your family and friends IN ADVANCE, preferably before you even book the holiday. Having chosen you as skipper, they have to understand that your word is LAW on board. If they can not accept this then do not accept the position. If you are the only one with sailing experience you can always accept the position of navigator, and let someone else be skipper, however if the crew can not all accept your original conditions you would be well advised not to make the trip, as the chances of failure are very high.

It has to be understood that the skipper's authority is not only confined to emergency situations where you are about to hit rocks (they will certainly accept commands then) but have to cover all the mundane daily tasks involved in living on board.

For example, there are 6 men in the crew, it has been a long and exhausting day and you have just enjoyed a magnificent dinner of fried fish, which you have bought at the local market, washed down with a sufficiency of good local white wine and are now sitting together to enjoy a coffee and brandy. BUT there is a huge pile of dirty plates, pans - approaching deck-high. Who is going to do the washing-up, when everyone is tired and a volunteer does not appear? To leave them will smell the cabin out - having eaten fish. But it has to be done and you have to ask, or eventually command, someone to spend the next hour doing the unpleasant job. If you don't, then what started out as a very pleasant evening will end up with arguments as to who will do what, and when - and it will all be your fault !

This example may be extreme but you would be surprised how many holidays are spoiled because these seemingly trivial issues are not handled properly. If the crew chose you as skipper they must accept your word as law. Good leadership skills by you, making sure that the crew all share the dirty jobs, as well as the rewarding ones, including yourself in the various domestic tasks, will ensure a happy ship and a subsequently enjoyable holiday.

b. You are the crew - and you have to choose the Skipper

Again, an early decision is by far the best. If more than one crew member has sailing experience choose the one with the additional leadership skills rather, than the purely technical sailor. You should choose someone you respect and whose orders you will follow without question.

Respect on someone's skills has nothing to do with age. How many children these days know more about computers than their fathers ??

During the trip you must follow the skipper's orders without question. If the skipper appears to be picking on you and you seem to be getting more than your share of a particular job - don't argue in front of the rest of the crew, just do it - and then have a quiet word with the skipper about your feelings quietly and in private later.

c. You hired a professional skipper for your holiday

Well, this is an article by itself and will be published separately in the short future.

Bluetooth Basics

The technology of Bluetooth wireless is a short range communications method intended to replace the cables that connect portable or fixed devices while maintaining the highest levels of security.

The key features offered by Bluetooth include low power and low cost. The specification in Bluetooth defines a uniform structure for a wide range of devices to communicate and connect with one another.

The technology behind Bluetooth has achieved global satisfaction such as enabled devices, almost everywhere in the world. Bluetooth devices will connect and communicate without wires through short range and networks known as piconets.

Each device will simultaneously communicate with up to seven other devices within a single piconet, meaning that each device can also belong to several piconets simultaneously. The piconets are dynamically established as Bluetooth enabled devices enter and leave the proximity of radio.

A fundamental to Bluetooth strength is the ability to handle both data and voice transmissions simultaneously. This will enable users to enjoy varieties of innovative solutions such as hands free talking, printing and fax capabilities, and other applications.

Specifications Unlike other standards of wireless, the Bluetooth specification gives product developers both a link layer and application layer definitions, which will help support data and voice applications.

Spectrum The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal.

Interference The adaptive frequency hopping of Bluetooth technology was designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum. Adaptive frequency hopping (AFH) works well within the spectrum to take full advantage of the frequency available.

AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they are using other technologies along with Bluetooth.

Ten Reasons You Should Use Bluetooth

If you are one of the many people who wonder exactly what Bluetooth technology is, you're about to get a brief rundown.

1) Bluetooth provides the ability for items that often need to be hard wired to be completely wireless. It allows you to use your laptop, cell phones, and hand held computer without being limited by cords, wires, and connections. In other words, Bluetooth technology allows portable devices to be truly portable. 2) Bluetooth is a surprisingly affordable option when compared to similar technologies. Because Bluetooth is inexpensive for companies to utilize they are also willing to pass the savings along to consumers. 3) Perhaps the greatest thing about Bluetooth for the average consumer is the fact that it is easy to use. There are no complicated sequences of keys you have to learn in order to make use of your Bluetooth devices. 4) Another winning fact about Bluetooth devices is that they will work with other Bluetooth enabled devices. If you switch from a Motorola phone to a Samsung phone (provided they are both Bluetooth capable) you will not have to be a new set of accessories in order for them to work with your phone. 5) Low interference is another bonus for these devices. People often find that wireless devices receive constant interference by others operating on the same frequencies. This is not an issue with Bluetooth as it utilizes technologies that limit the risk of this occurrence. 6) Lower energy consumption is another benefit of Bluetooth over similar devices. This means you will drain your battery less often or use less electricity in the use of your Bluetooth devices. 7) Bluetooth allows compatible devices to share data and voice communication. This means that you can drive more safely while talking on your cell phone. 8) You have the option of creating a Personal Area Network (PAN) with your Bluetooth device. This network operates within a 30 foot range and can have as many as 7 devices connected. 9) Bluetooth is emerging technology. As such, they are constantly offering better features and services. They are also behaving very wisely in creating consumer loyalty by making their new technologies compatible with existing technologies. This means that you can continuously upgrade your devices. 10) We've seen many fads come and go in the cellular community. Bluetooth, however, seems to be in it for the long haul. They are committed to raising the bar for wireless technology and have in the process gained many loyal customers and fans.

If you rely on cellular technology isn't it time you checked out how Bluetooth could benefit you?

Travelling Is Easier With A Pda And A Bluetooth Receiver

Traveling is always easier if you take as little with you as humanly possible. It?s always the intention while traveling to carry only to what is most necessary. This is not always an obtainable goal, especially when you are venturing into parts unknown. In addition to the usual essentials, a sizable map and navigational equipment become necessary.

With the unveiling of GPS technology, traveling with maps and huge navigational devices becomes unneeded; a traveler need only carry a GPS receiver. A GPS receiver determines one?s exact position on earth by deciphering the information it receives from GPS satellites. With the assistance of other electronic devices, the GPS receiver will precisely determine your correct location on a map.

For even more even more functions and ease of use, GPS receivers can be used with other mobile devices. The PDA is one of the most frequently used mobile products for this purpose. PDAs make the perfect partner to the GPS receiver because of their unique features, such as a colored screen to display maps and hard drive space for map storage. And PDAs are light compared to other mobile devices such as notebook computers.

There is a problem with using a PDA with a GPS device, however. They do not always integrate well. GPS receivers are normally connected to PDAs using a CompactFlash (CF) card or USB wires. Because some GPS receivers are quite large, attaching it to your PDA using CF can make it too large. Using the USB wires, however, can make your GPS receiver difficult to use and limit its usefulness.

So what could be the solution to this problem? A Bluetooth GPS reciver.

The Bluetooth Solution

Bluetooth wireless technology is the open standard for wireless communication. As long as the two electronic devices are with 10 meters of each other, Bluetooth technology will allow them to send and receive signals and transfer data. No wires are necessary.

Bluetooth GPS Recevier

The Bluetooth GPS receiver is simply a receiver that uses the Bluetooth technology and electronics to transmit GPS data to a mobile device. However, they must share the same technology. For example, if a Bluetooth GPS receiver will be used with a PDA, the PDA must have built-in Bluetooth technology.

The Bluetooth GPS receivers used with the Bluetooth capable PDAs offer many advantages over an ordinary GPS unit, which is connected to the PDA using CompactFlash or USB wires. These advantages include the ability to use wireless connections between the devices. Without wires to limit positioning between the Bluetooth GPS receiver and the PDA, you can place the two devices at their most advantageous locations. For example, if you are using your Bluetooth GPS receiver in your car, you can place the device where it has a clear view of the sky. Then you can place your PDA on your dashboard and have optimum screen visibility. Because the wires are not used to connect the two devices, their positioning will not hamper your driving. Also, because you won?t need to use Bluetooth?s CompactFlash slot, you can use it for other things, such as storing maps or software to optimize the GPS navigation.

Aside from these two advantages, the Bluetooth GPS receiver units have other features, although most of them are brand or unit specific. Generally, Bluetooth GPS receiver units now have pre-stored US maps, point-of-interest (POI databases and route recalculation functions.

Hands-Free Units With Bluetooth Launched By Parrot

Driving does require you to have your full concentration on the road ahead. It is also very essential that your mind does not wander anywhere else. However, because of the frantic pace of the world today, it seems like anywhere a person goes, there is always something that you would need to take care of - bills to be paid, friends asking for advice, family members giving you last minute instructions, bosses looking for report, clients asking for a meeting, and many others.

Good thing that Parrot, a company that has already become a specialist in Bluetooth hands-free telephony, has been able to create the BTHFU (Bluetooth Hands-Free Units) for cars and vehicles. In fact, Parrot is actually a member and the current chair of the Bluetooth SIG Automobile working group. According to the company, the products that they are designing and developing have been made just especially for vehicles. And the BTHFU has been actually created along with the company Visteon. This new unit would be coming with digital signal processing, noise reduction features, as well as echo cancellation. You would be able to find this one in the Nissan Bluebird Sylphy which would be roaming the streets of China.

Henri Seydoux is the founder and the CEO of Parrot and he comments, "We are very happy to collaborate with Visteon, one of the leading automotive equipment suppliers worldwide, on the development of hands-free systems which should become widely applicable as a car standard equipment."

This kind of innovation and change in the automotive industry just simply shows that as everything in the world evolves, the automotive industry is also evolving along and simply not just in terms of Buick parts and the like. During the time that the passengers needed much protection during crashes, the air bags were created. During the time when people were very much affected by high gas prices, hybrid vehicles were sent out. And during this time when communication and being in touch is a very important aspect of life, the Bluetooth Hands Free Units became a reality.

Security Of Your Bluetooth Devices

These days, all forms of communication technology face the problem of security and theft of personal details , and 'bluetooth' is no exception to these concerns, nor should it be. Most everybody knows by now that all email programs and networks need protection and security. What users of 'bluetooth' really do need to comprehend is that 'bluetooth' requires the same protection measures as email programs and other communication programs.

The upside for 'bluetooth' users is that the recent breaches-of-security scares, as in all scares, are usually way over - dramatized and blown way out of all reasonable proportions. The reality being told, these issues are simple to control, using several protocols now in place to ensure protection for 'bluetooth' technology.

It's very true that there has been several 'bluetooth' phones subject to attack and have been hacked into. The majority of devices which are hacked are usually those that don't use any form of protection or security at all.

Bluetooth specialists say that, in order for anyone to hack their way into a 'bluetooth' device, the person hacking has to: 1. Convince two coupled devices to shut down their link. 2. Take the packets that are required to resend the pin. 3. Unscramble the pin. Of course, the hacker most certainly will be within limit of the phone, and using extremely costly developer - style , high quality, equipment. Top specialists strongly suggest you use a longer pin, using more than 8 digits as being the minimum recommended.

Basics of security. The "pairing procedure" is the main fundamental level of protection for 'bluetooth' devices. Pairing, is the linking of two, or even more, 'bluetooth' devices which identify themselves by the profiles they have in common - in the majority of cases they both must use the identical pin.

The central specifications for 'bluetooth' use an encoding algorithm, that is is absolutely and safe and secure . As soon as the devices link up, they too become completely protected.

Until they have actually linked, the 'bluetooth' devices won't make contact with each other. Due to the pairing technique and that the range is very short it is - 'bluetooth' technology is thought to be well and truly secured.

As the recent news has shown, expert hackers possess sophisticated ways to get past most levels of fundamental security. There are ways to get protection from this type of threat, as you can have installed software to stop hackers from hacking their way in.

Now that 'bluetooth' has become popular and more in demand, it's no wonder safety is constantly in the public eye. As 'bluetooth' gets more popular and more improved, security can usually be something that no one will ever take lightly.

If you've been thinking about 'bluetooth' protection in the past, be safe in the knowledge that newer devices can give significant and much-improved protection. Stopping hackers from creeping in is something every phone-owner is thinking long and hard about - and the maker's are very much aware of this.

Bluetooth Headsets - Reducing Possible Health Risks in Your Busy Lifestyle

Bluetooth Headsets have redefined the art of talking over the telephone. No wires, no hands, nothing at all! Just put the device on your ear and you are communicating at ease with the rest of the world. You have the flexibility to do anything while talking. Not only does this add to convenience, but you get to gain from a health perspective as well. This article tells you all about these advantages with Bluetooth Headsets.

Bluetooth Headsets-Reduce Health Risks

Research has proved that holding phones close to your ear (hence head) increases health risks. There is a possibility of developing brain tumors. Electromagnetic radiation emitted from cell phones affect the body's cells, brain and immune system. A wide range of diseases, from cancer to Alzheimer's, may develop due to such harmful exposures. Various experiments in Finland, Sweden and other places have confirmed these concerns.

Experiments conducted on mice have shown that harmful radiations from cell phones affect body cells and it is believed that the findings would also hold true for human beings as well. A group of scientists in Finland conducted a study and published a report in 2002 where they highlighted the negative effects of electromagnetic radiation emanating from phones on human brain tissue.

A similar study conducted in Sweden showed that the people using mobiles phones had a 30% higher probability of developing brain tumors compared to persons who preferred some other mode of communication. Considering these health risks, it is always advisable to keep the phone set away from your ear. Bluetooth Headsets can give you this unique advantage.

You may also sometimes get entangled in the wires of your telephone or run the risk of having an accident while driving and holding your mobile phone. This is very risky. A Bluetooth Headset is a hands-free, wire-free device that helps you to conveniently avoid all these risks.

Bluetooth Headsets-The Compatibility Factor

Setting new standards in wireless connectivity, Bluetooth Headsets have very high compatibility with a wide range of telecom appliances. You can connect different devices across diverse platforms by this. Two appliances enabled with this technology can access one another even when separated by about 30 feet. However, this varies with instruments and you must check the product specifications before buying the devices.

Differences with Wi-Fi

Both provide facilities of wireless networking using radio waves and are new-generation communication tools. But, there are some basic differences. Bluetooth is a short-range (30 feet), low power connectivity system with moderately fast transmission speeds of 800 kilobits per second. Developed in 1994, Bluetooth provides wireless, point-to-point connectivity for mobile phones, PDAs, Notebooks, Printers etc. If any two devices are Bluetooth enabled, a wireless connection can be set up between them for transfer of data. Say, if a PC and a Printer are Bluetooth enabled, you can transfer data from the computer to the printer without connecting through a cable.

Wi-Fi stands for Wireless Fidelity. Appearing in the market in late 1998, Wi-Fi provides access to Ethernet networks such as LAN, WAN or the Internet at super-fast speeds of up to 11 megabits per second. You can make connections with Wi-Fi networks even up to 300 feet. If your Notebook is Wi-Fi enabled, you can surf the Internet at broadband speed without cable connections.

Bluetooth Headsets--Well Known Brands

All well-known telecom manufacturers are marketing products enabled with this technology and Bluetooth Headsets are regular features with most top-end products.

The popular versions include:

The Truth About Bluetooth Headsets

Everywhere you look, companies are producing Bluetooth Headsets faster than the rising cost of gasoline. Nokia, Sony, even Verizon Wireless is unveiling the newest trend in Blue Tooth technology, the headset. Demand is high, and understandably so. Studies have shown that many accidents occur while people are dually driving and speaking on cell phones. A Blue Tooth headset can solve the problem by freeing both hands for the wheel and allowing people to focus their attention on the task at hand-driving.

Now, for those who are unfamiliar with Blue Tooth and headsets that utilize this mobile technology, don't let the name fool you. Maybe you have conjured up images of geeky brains in MIT walking down the street with electric pulsating wires stemming from football helmets as they signal to each other in modified walkie talkies- nothing could be further from the truth. Today's modern headsets are little more than a comfortable, small and lightweight piece that rests over the ear. This technology is revolutionizing the way people communicate wirelessly and if modern manufacturers and patents are a clue to the future, will soon replace the traditional hand held cell phone.

Not exactly a headset, but you can see a great pair of Blue Tooth wireless sunglasses worn by "Dog" on the A&E hit series, "Dog the Bounty Hunter". I wonder what other nifty gadgets the Dog has on the show! But if you look closely, you can catch the Dog speaking into his glasses (no and not in common "Bond" spy fashion) and see the rest of the team hear his words loud and clear.

With the announcement that Verizon is releasing the Logitech Headset and making it available to all of their wireless customers, we are sure to see a sudden rise in the amount of Bluetooth headset wearers.

As testament to the sudden interest in headsets, the company Late On has just received an order for their mobile headsets to be released. These headsets are so versatile; they can be clipped on to a collar and are perfect for conducting phone conversations, as well as for listening to MP3 files.

One of the world's leading manufacturers of mobile phones is also embracing the design of Blue Tooth headsets, Nokia. With three new Nokia headsets soon to be released we can see that the major companies are investing their own dollars in the production of these wireless devices that give users greater freedom and mobility. The world is pulling the wires on many of their devices and now we can see that Blue Tooth headsets are winning the race in mobile technology, with hands waving freely at the finish line.

Bluetooth Headsets Explained

For a wireless headset, you can do no wrong in choosing a Bluetooth headset. They are not as compact as a wired headset, and certainly not as light, but you have to take into consideration the fact that the wireless Bluetooth headset needs a battery.

The more popular choice for a Bluetooth headset is the one with the loop around the ear so that it is held in place. It may seem that it is not as secure as the on that is designed to be jammed into your ear, but it is found to be way more comfortable.

You will want to check around to see the different prices. Looking online is where you will probably find the cheaper Bluetooth headset, and if you are willing to wait a few weeks for it, then this is probably where you should go.

Go to an electronics store and see if they have one you can try. You want to make sure that you can hear well with it, and that you can figure out the controls and work with it easily.

You will want to know how long the battery generally lasts and figure out if you want one that you need to charge or one that allows you to just put in a new battery. It is important that the headset is also compatible with your phone.

Choosing a Bluetooth headset is a good choice. It is a very popular brand and you can't put a price on safety.

3 Bluetooth Issues, 1 Bluetooth Weapon The FBI is Worried About

Bluetooth may become an headache for law enforcement.

Some of the bluetooth technology security issues are commonly known
- but one (see #2) is something almost no one knows about.

The FBI knows about this "blue weapon" and it is pretty worried for
good reasons.

The four potential problems:

1- Unauthorized access
A bluetooth device can possibly be surreptitiously accessed and have
it's information downloaded. Especially since most devices by default
come with security disabled.

Criminals as well as law enforcement itself could potentially use or
misuse this capability.

Accessing and downloading all kinds of information from bluetooth
devices make the possibility of phone cloning and modification of
information, as well as identity theft a real concern.

2- Anonymous communication
Furthermore, there's a method of communication using bluetooth that
allow for anonymous messaging.

Criminals could use this capability to facilitate their illicit
activities by communicating with each other without having law
enforcement listening in on their conversations.

Here's the basic of how it works...

When two bluetooth devices first start to communicate with each other,
they need to authenticate each other. This is called "handshake".

As they handshake there is a designated area of this part of the
communication process that is utilized to transmit the name of one
device to the other.

This designated area can allow criminals (or just about anyone) to
cram in short three or four word messages in there - thus providing
criminals with a three/four word anonymous communication capability
from one device to another where law enforcement is blind to this
communication taking place.

It's possible to send an anonymous message of up to 248 characters,
to be exact.

Something authorities are genuinely worried about.

3- Gaining access to data on a cell phone
With early versions of bluetooth-enabled cell phones, it's possible to
connect and gain access to some of the data on this cell phone,
including its calendar and phonebook.

This is done with a specific piece of software we won't mention here.

4- Sniffing
While not a threat in itself, sniffing is more commonly known. It's
about using a tool designed to scan and identify devices.

Since most bluetooth devices usually have their security disabled by
default, a hacker will often be able to compromise the security of
such devices pretty easily.

Identity theft, phone cloning and data manipulation of computer files
are then posssible, as mentioned at t he beginning of this article.

In conclusion
While new wireless technologies are always touted and appreciated, one
should always make sure he knows how to utilize it as securely as
possible.

If this means consulting with an expert or doing your own research,
then do it because the security of your data is probably worth gold to
you...

...and may be worth gold to others as well...

Infrared And Bluetooth: Connecting Things Easier

With different electrical devices produced everyday, the problem of connecting things is becoming more and more complex. The system that comprises the computers and other electronic devices makes use of varieties of connecting wires, cables and the likes. These parts communicate trough light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.

To simplify things, a solution was created to streamline the process of connections- bluetooth.

Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.

Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.

Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.

It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.

In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.

However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.

Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.

The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.

The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.

Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.
