PAN technology overview

Sensors can be combined with WPAN(wireless personal area network) technology to access or communicate with Distributed Environment.

There are several WPAN technologies available; Bluetooth, UWB(Ultra-wide band), and Zigbee.
Bluetooth is nowadays well-known technology.
UWB technology is one of the wireless transmission technology, it can deliver digital data with lower power, more data using wide-spread spectrum in short range. Zigbee is also alternative , it has low complexity for design, low cost, the price is rather cheaper than Bluetooth low power consumption. However its data rate is low , maximum 250kbps,
