Blue Tooth Headset Cell Phone Technology

Blue tooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Blue tooth" is borrowed from Harald Bluetooth, who was a king in Denmark more than 1,000 years ago.

Phone technology cell

Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets. The main usage of bluetooth was in the cellular phones.These cover a wide range of wireless usage.Some of the mobile phones have low power audio communication ,These bluetooth helps them to gain better wireless facility, so has to enable receiving good signals.

How it works?

The wireless signals transmitted in Bluetooth reach over short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps.
Bluetooth networks feature a dynamic topology called a piconet or PAN. Piconets contain a minimum of two and a maximum of eight Bluetooth peer devices. Devices communicate using protocols that are part of the Bluetooth Specification. Version 1.1 of the specification is in widespread use today with versions 1.2 and 2.0 under development.
Although the Bluetooth standard utilizes the same 2.4 Ghz range as 802.11b and 802.11g, Bluetooth technology is not a suitable Wi-Fi replacement. Compared to Wi-Fi, Bluetooth networking is much slower, a bit more limited in range, and supports many fewer devices.
As is true for Wi-Fi and other wireless technologies today, concerns with Bluetooth include security and interoperability with other networking standards. Practical adoption of the technology has not yet lived up to the initial industry hype around Bluetooth

Comments

Bluetooth neither helps nor hurts the accuracy of voice recognition, which is also used to control the audio and navigation systems. As for emergency assistance services in cars such as OnStar and Mercedes-Benz's TeleAid, they require an integrated cell phone. OnStar, which has offered optional cellular calling, should be more desirable this year, now that it finally offers digital service while retaining analog service that works better out in the boondocks.
