Wireless technologies
|
Wireless technology in a variety of forms is an area of electronics that is developing and growing particularly fast. Wirless LAN
(WLAN) technology including Wi-Fi (IEEE 802.11), Bluetooth, Ultra-Wide Band (UWB),
Wimax, Zigbee, and more are all growing and finding their own market areas. As a result wireless technology is being more widely used and found in many new applications.
The development of wireless technologies
IEEE 802.11 / Wi-Fi
In recent years Wi-Fi has become increasingly popular. Enabling people to link computers to wireless LANs either to give greater flexibility in offices, to reduce costs by not having to install wired networks, or just to access a computer network when using a "hotspot" in a cafe, hotel, airport lounge or wherever, this technology has become a major force in the wireless industry in recent months and years.

Bluetooth
Bluetooth is now a well established technology, providing wire-less connectivity for a wide variety of devices from headsets to mobile phones.

(EDR) and other new features
Zigbee / IEEE 802.15.4
Zigbee is a relatively new standard that is aimed at the data collection, remote sensing and control applications. It has a particularly robust structure that enables it to operate reliably in harsh radio environments.

WiMax
WiMax is a standard that is of growing importance offering high data rate communications over a wide or metropolitan area.

Ultra-Wide Band (UWB)
Ultra Wide band is a technology that shows an enormous amount of potential. With data rates in excess of 1 Gbps being demonstrated, it may be ideal for many short range applications.
