Using A Bluetooth Headset With A Hearing Aid.

Many people that have to use hearing aid also want to use a cell phone. Quite often the hearing aid frequencies interfere with the frequency used by cell phones. It's quite common to experience squealing when trying to use a cell phone with your hearing aid.

If your hearing aid isn't very severe, then you may be able to hear well enough to take your hearing aid out and use the phone without the hearing aid.

Manufacturers of hearing aids are quite innovative, they are always finding new features to add to the hearing aids.

If you wanted to use Bluetooth headsets with your hearing aid it may have been difficult before, however now you can buy a Bluetooth compatible headset, these enable users to talk on the phone like other people can normally.

Bluetooth is the name of a wireless radio system that can be used as a wireless headset. Bluetooth is a standard protocol which is compatible with Bluetooth enabled phones and PDA's. For more info see http://www.firsthearingaids.com/comparereviews/digital_hearing_aids.html

Ear level instrument (ELI) is a Bluetooth headset produced by Starkey, this headset works perfectly with most hearing aids. The ELI is very small and considerably light, there is a built in battery which you can recharge. It uses a digital system to minimise the interference.

The only problems with the ELI is that they are relatively new, and so they are quite difficult to come by.

The ELI is positioned behind the ear, it uses the telecoil system to ??talk' to a telecoil enabled hearing aid. This works similar to when talking on a conventional phone with telecoils.

The ELI battery does not last very long, however because it's rechargeable you can charge it up instead of having to replace it.

So how do you know whether or not you can use a Bluetooth headset with your phone? Well your cell phone should have a Bluetooth logo somewhere on the case, or box. You can also look in the product specifications.

If your handset is Bluetooth enabled then you should be able to use an ELI, however it is worth checking compatibility before purchasing.

Key Learning Points Of Bluetooth

Key Learning Points Of Bluetooth

Bluetooth is easily the best in wireless handheld technology. When it comes to learning, Bluetooth can get quite complicated. To help you, you'll find the key learning points of Bluetooth below:

1. Bluetooth is an energy efficient, low overhead communication protocol that's ideal for interdevice communications.

2. Unlike infrared, Bluetooth doesn't require a line of sight.

3. Depending on the implementation, Bluetooth can have a range of up to 100 meters.

4. The specification of Bluetooth consists of a Foundation Profile Document and a Foundation Core Document.

5. The protocol stack for Bluetooth consists of core protocols, cable protocols, and even adapted protocols.

6. The transmitter operates around the 2.4 GHz frequency band.

7. The data channel will change frequency, or hops, 1,600 times in a second, between the 79 allocated channels in the ISM band.

8. Bluetooth utilizes a spread spectrum frequency hopping RF characteristic to ensure that independant networking operates when the other devices are in range.

9. A piconet is formed when one or more devices open up a channel of communication.

10. A piconet can have a master and up to seven slaves.

11. Communication of the interdevice is based on the concepts of channels.

12. All Bluetooth devices are capable of transmitting voice.

13. The channel has a total capacity of 1 MB per second.

14. There are two types of channels with Bluetooth - SCO (Synchronous Connection Oriented) and ACL (Asynchronous Connectionless).

15. The SCO channels are time oriented, and are therefore primarily used for transferring time critical data such as voice.

16. ACL channels are normally used for communicating data.

17. Data contained in a packet can be up to 2,745 bits in length.

18. In a single piconet, there can be up to three SCO links containing 64,000 bits a second each.

19. To avoid collision and timing problems, SCO links are reserved slots that are set up by the master.

20. The masters can support up to three SCO links with either one, two, or three slaves.

21. The slots that aren't reserved for SCO links can be used as ACL links.

22. The LMP (Link Management Protocol) will handle link level security, error corrections, and the establishment of communications links.

23. The LMP packets will have priority over user packets that originate and form the L2CAP layer.

24. The L2CAP layer will ensure an acceptable quality of service.

25. No more than one ACL link can exist at the L2CAP layer.

A Simple Guide to Wireless Networking

 

Most folks want that laptop for work, school, or college. Most laptops these days are Wi-Fi enabled. That means that they have the wireless hardware and software built into the computer. To the average consumer, wireless is a form of magic. You turn it on and it works, right? Not always. Understanding the basics to wireless will help avoid frustration and headaches.

First, before we get into the basics of wireless networking, I have a few opinions to express.

It seems that everybody wants to go wireless with their laptops and desktop PC?s. Wireless for laptops makes sense, since they get moved around between work and home and points in between. You can always connect using the Wi-Fi network at work or steal bandwidth from someone else. There are hotspots all over. There are ethical questions involved with ?borrowing? your neighbor?s signal. Let your conscience be your guide.

Wireless for desktops is an open subject. Since most of us usually set our desktops up on our home or office workstations, they tend not to move around. The only benefit of having a wireless desktop is that you don?t have the expense and trouble of running Ethernet cable around your house. If you are not a DYI?er, an Ethernet cable installation is an extra outlay. If you?re lucky, your present PC is only a few feet away from your Broadband Modem. I personally prefer to have all my stationary PC?s hooked up with Cat 5 Ethernet cables. That way I don?t load up the wireless bandwidth on the router. We?ll talk more on bandwidth later.

There are hardware requirements to wireless networking. These are the things you need to communicate.

At home you need:

• (1) a Broadband internet connection (Cable or DSL modem),
• (2) a router to broadcast the wireless signal,
• (3) a wireless enabled computer.

You cannot set up a wireless network using a Dial-Up connection. Period.

I recommend that you power off your Broadband Modem and any existing computer systems before you begin the installation of the wireless router. The computing equipment will start to negotiate with your router automatically on start up. This will get you on the network without confusion.

The router and existing PC?s should not need any further configuration. The default or current settings should work. Your PC should already be set to DHCP in your Network Connections TCP/IP properties window. If it weren?t you would not have been able to connect to your ISP. This is a default setting of your PC.

The Broadband internet connection gear should already be present. That?s the Cable or DSL Modem that your Internet Service Provider installed when you got their service. It?s connected to the Cable or DSL filter connection coming from your wall. The Modem has two connectors as a rule. One for the Cable or DSL data into the Modem, and one RJ45 connector you probably have connected to the computer you have in service now.

You?ll need to unplug the Ethernet cable between the computer and the Modem. Reconnect that cable to your wireless router. It goes into a RJ45 connector usually labeled ?WAN? for Wide Area Network. The only other connection you will need to make is to connect another Ethernet cable between from one of the wired ports on the back of the router to your PC. There are usually 4 of them. Any one will do to reconnect your existing PC so it?s on the network. The existing PC will get it?s internet connection through this port. Your router?s default settings should allow you to start connecting to your Wi-Fi enabled computers.

If all the cables are correctly placed, you should now be able to get on the Internet from you existing computers and your wireless computers.

Some quick notes of interest:

• (A) Your Wi-Fi router is transmitting and receiving in the 2.4MHZ range. So are your Wi-Fi enabled computers. This is the same frequency range of a number of cordless telephones. You may have interference on your cordless phones once the Wi-Fi network is installed. If this occurs you?ll need to get 5.8 MHZ phones or put up with the noise.
• (B) One of the most common questions I get is ?I bought a wireless laptop and I can?t get on the internet. Why not?? If your wireless router is installed properly, then your wireless laptop may need configuration. Go to your Network Places or Network Neighborhood for a wizard to help you set up your computer for wireless.
• (C) Bandwidth is the volume of traffic you can sustain through your network. The more devices using the Wi-Fi network, the slower the network uploads/downloads will be.

Remember, your wireless network works a lot like your cordless phone system. You need a transmitter/receiver at each end. Think of the router as the base station and the wireless PC as the handset. You can?t talk on your cordless phone if the base station is unplugged. So without a wireless router in service, you can?t communicate with the Internet. Hotspots are just spillover signal from someone?s wireless router.
