One emerging wireless technology called Bluetooth will make mobile devices as standard as a stethoscope. Oddly named after a Danish king who ruled a thousand years ago, Bluetooth is a short-range wireless local area network operating on the 2.4 GHz frequency that facilitates communications between enabled devices within 35 feet of each other. Bluetooth uses radio technology to transmit voice and data, thus eliminating cables. Unlike infrared, line-of-sight requirements do not limit Bluetooth, and at up to 2MB per second, the data-transmission rate is much greater. With this technology, a single device can connect with up to 200 others and automatically share information. Bluetooth users literally can synchronize all of their enabled devices simply by entering the room. The organization working to develop this technology is the Bluetooth Special Interest Group. They are an industry group consisting of leaders in the telecommunications, computing, and networking industries that are driving development of the technology and bringing it to market.
