The Many Uses Of Bluetooth Phones

Bluetooth technology allows different devices from different manufacturers (and, in the case of bluetooth phones, different providers) to "talk" to each other on a shared wireless platform.

Essentially an ultra low power radio signal, Bluetooth allows wireless access to certain devices within a range of about 30 feet. This all sounds complicated but the net effect of this technology has added flexibility and convenience for those who frequently rely on handheld consumer electronics such as phones, PDAs and cameras. You may not realize it, but most cell phones come with Bluetooth as a standard feature.  Let's look at some of those features.

Shared Voice

It is probably no surprise that Bluetooth phones are capable of sharing voice communications with a compatible Bluetooth headset. However, with the same cell phones service, you may also be capable of establishing a connection to the internet. By using Bluetooth technology, your phone can connect to your laptop. You can then use your laptop to surf the web or send and receive email. It's as simple as syncing the two devices.

Hands Free Devices

Other accessories available for mobile phones with Bluetooth technology include hands-free headsets, car and motorcycle kits and speakers and speaker phones. The range of use of your accessories depends on the level of Bluetooth technology that your phone employs.

It will most likely use either version 3.0 or 4.0 and have a WiFi connection available between accessories and the Bluetooth cell phone. Version 2.0 can reach a range of up to 300 feet in some cases. Check your particular model to see what version you have to get a better idea of what range you can expect.

Several options exist for Bluetooth cell phone car kits from your local consumer electronics store that plug directly into your car and are accessible wirelessly through a headset or speaker phone. Push button or voice options exist for calling and music selections in many of these devices, and your Bluetooth cell phone is functional as soon as you turn on your car or motorcycle.  Many car makers are offering it as an option in their new cars.

Bluetooth phones allow you to have constant, hassle-free, wire-free phone use, whether your in the car, at home, or while working. Handy accessories give you hands-free voice and data communication, as well as nifty tricks to keep you connected to the internet, wherever you may be. Bluetooth is both an easy and inexpensive way to link up with the rest of the world.

Bluetooth Versions/History

Bluetooth v1.2

  • Backward compatible with v1.1, faster connection and discovery.
  • Recovered confrontation to radio frequency interference by avoiding the use of crowded frequencies in the hopping sequence.
  • Data transmission speed up to 721 kbit / s.

Bluetooth v2.0

  • Backward compatible with the previous v1.2.
  • Enhanced Data Rate (EDR) for faster data transfer.
  • The nominal rate of EDR is about 3 Mbit / s

Bluetooth v2.1

  • Backward compatible with v1.2.
  • Uses secure simple pairing (SSP) to improve a better pairing experience for Bluetooth devices.
  • Uses sniff sub rating, which reduces the power consumption in low-power mode.

Bluetooth v3.0

  • Backward compatible with v2.1.
  • Bluetooth 3.0 provides theoretical data transfer speeds of up to 24 Mbit / s.
  • For high data rate traffic this version uses the adjacent 802.11 link.

Bluetooth v4.0

  • Backward compatible with v3.0.
  • Provides faster speed in data transmission than the earlier version.
  • It comes with greatly reduced power consuming, as if it does not require any power at all to function.
  • It provides more security in data transmission than the earlier version.
Bluetooth technology is developing from day to day and one major feature of any version is just making the newer version superior over the earlier version. However more updated versions of Bluetooth technology will be keep on coming in future to meet all the requirements of the users.
