Copyright 2003 Applied Logic Engineering Wireless Technology Personal Area Network (PAN) Local Area Network (LAN) Wide Area Network (WAN)
3
Copyright 2003 Applied Logic Engineering Commercial Wireless Networks Personal Area Network (PAN) Examples : IRDA, Bluetooth Short range file transfer Low bandwidth (up to 1mb per second) Local Area Network (LAN) Example : 802.11b An extension of an existing corporate wired LAN High bandwidth (5Mb per second) Wide Area Network (WAN) Examples : Cellular, CDPD Uses a dial up (phone) connection Extremely low bandwidth (14.4kb per second)

Copyright 2003 Applied Logic Engineering Bluetooth Essentially a cable eliminator Short range, wireless comm protocol Limited to about 30’ between devices Unlike 802.11b, NOT a wireless extension of the corporate LAN Implementation: Add-in cards for PCs, PDAs (may be built in in future)
5
Copyright 2003 Applied Logic Engineering Wireless LAN 802.11 is the key technology here Essentially provides a wireless extension of your existing corporate LAN. Versions – 802.11b – currently widely deployed 802.11a – higher bandwidth 802.11g – higher bandwidth, backward compatible with 802.11b.

Copyright 2003 Applied Logic Engineering Wide Area Network Uses cellular / digital cellular networks Provides essentially world-wide access Currently low bandwidth (<19k bps) 3G networks promise improvement
