Wireless Bluetooth Technology
Bluetooth is a wireless technology which allows devices to inter-connect and communicate with each other. Radio waves are electromagnetic waves and have different frequencies. This technology is a radio frequency. Similar to the analogue radio, or FM radio. Bluetooth works on 2.45GHz frequency.
Bluetooth: Named after the Danish king, Harold Bluetooth,was the first to emerge, several devices like mobile phones, PDAs, headsets, keyboards, mice, medical equipment and even cars now come with this feature. Due to its low cost, manufacturers are willing to implement this technology in most devices. It is designed for short range communications with a range of about 10m. As a result, it consumes less power and are suited for very small battery powered devices and portable devices. Problems associated when devices communicate via infrared or cables are removed. Infrared requires a line of sight, bluetooth only needs to be in reasonable vicinity. As cables are not required, it would be less cumbersome carrying a personal bluetooth device and space would be less cluttered. As Bluetooth devices automatically communicate with each other, it requires very little from the user. Bluetooth allows for a wireless Personal Area Network (PAN) with it's short range.
Computer requirements:
A personal computer that does not have embedded Bluetooth can be used with a Bluetooth adapter that will enable the PC to communicate with other Bluetooth devices (such as mobile phones, mouse and keyboards). While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others will require an external one in the form of a dongle.
Unlike its predecessor, IrDA, which requires a separate adapter for each device, Bluetooth allows multiple devices to communicate with a computer over a single adapter.
Bluetooth v3.0 + HS
Version 3.0 + HS of the Bluetooth Core Specification was adopted by the Bluetooth SIG on 21 April 2009. Bluetooth 3.0+HS provides theoretical data transfer speeds of up to 24 Mbit/s, though not over the Bluetooth link itself. Instead, the Bluetooth link is used for negotiation and establishment, and the high data rate traffic is carried over a collocated 802.11 link.
The main new feature is AMP (Alternate MAC/PHY), the addition of 802.11 as a high speed transport. The High-Speed part of the specification is not mandatory, and hence only devices sporting the "+HS" will actually support the Bluetooth over 802.11 high-speed data transfer. A Bluetooth 3.0 device without the "+HS" suffix will not support High Speed, and needs to only support a feature introduced in Core Specification Version 3.0 or earlier Core Specification Addendum 1.
