vs. 3G Once upon a time, you could hardly open a business
magazine without finding a feature that praised 3G wireless
telephony as the answer to mobile Internet needs. That was venture
capital then. This is fiscally strapped now. In theory, 3G wireless
networks are capable of throughput up to 384Kbps, which still puts
them at the bottom end of 802.11b's range...
is a wireless LAN? A wireless LAN (WLAN) is a local area network
(LAN) without wires. WLANs have been around for more than a decade,
but are just beginning to gain momentum because of falling costs and
improved standards. WLANs transfer data through the air using radio
frequencies instead of cables.

802.11 Wireless LAN This document introduces the IEEE standard
802.11 for Wireless Local Area Network. The document also makes a
comparison to GSM cellular network, where the cell size could be
much larger. The paper discusses the basis outlining the network
planning process, such as frequency, scale of mobility, transmission
capacity needs and population variation. Finally the total network
planning process of a cellular network is introduced. The question
is how does the use of unlicensed frequency band affect the WLAN
network planning. Finally the study suggest what are the relevant
requirements for wireless communication with short range mobility.
It also suggests what GSM planning criteria can be omitted in the

the Reach of the Wireless LAN (11/02) Today, when you set up a
wireless network using a single 802.11b access point, you're lucky
if it has a range of 300 feet. And at about 100 feet, its speed
begins to drop. If you wish to improve its range, you have to setup
another antenna. Come this spring, all of this may change. Vivato, a
new networking company based in San Francisco, has announced a line
of Wi-Fi switches that, it claims, can extend the range of your
wireless network to several kilometers.

last, real wireless LAN security Introducing 802.1x and EAP (9/02)
After the IEEE recognized the shortcomings of WEP and 802.11, it
quickly came up with the 802.1x and EAP solution. A standard for
Port Based Access Control for both wired and wireless networking,
802.1x in itself does not make wireless networking secure. However,
combine 802.1x with the Extensible Authentication Protocol (EAP)
standard, and the gold standard in wireless network security is
born; it's now possible to resolve WEP's biggest liability: static
user and session keys.
