Bluetooth essays

Bluetooth essays Bluetooth has been the subject of much hype and media attention over the last couple of years. As various manufacturers prepare to launch products using Bluetooth technology, an unsuspecting public is about to be catapulted into the next stage of information technology. Bluetooth is a low cost, low power, short-range radio technology, originally developed as a cable replacement to connect devices such as mobile phone handsets, headsets, and portable computers. By enabling standardized wireless communications between any electrical devices, Bluetooth has created the notion of a Personal Area Network (PAN), a kind of close range wireless network that looks set to revolutionize the way people interact with the information technology landscape around them. Imagine transferring a list of contacts from your mobile telephone to your desktop without cables. Or accessing a corporate network without an Ethernet card; or using your mobile phone to buy food from a vending machine or a store. The Bluetooth specification is an open, global specification defining the complete system from the radio right up to the application level. The protocol stack is usually implemented partly in hardware and partly as software running on a microprocessor, with different implementations partitioning the functionality between hardware and software in different ways. Version 1.0 of the Bluetooth specification came out in 1999, but Bluetooth started five years earlier, in 1994, when Ericsson Mobile Communications initiated a study to investigate the feasibility of a low-power, low-cost radio interface between mobile phones and their accessories. Radio is not directional, and it does not need line of sight, so it has obvious advantages over the infra-red links previously used between handsets and devices. The specification was named after the tenth-century Danish Viking king Harald Bluetooth who unified Sca ...
