Wireless Tech Info

The following information is available about wireless systems (mostly Wireless LAN for just now). In case you missed it: The 802.11 standards are now freely available in PDF format.

Overview	Everything you NEVER wanted to know about wireless is here (in fairly simple terms).. the dreaded decibel, free space propagation, cable loss, antenna gain, links to places where people know what they are talking about and other horrible stuff that hurts the brain.
Calculators	Our versions of a number of useful wireless calculators including DB to Watt conversion (and vice versa), Free Space loss, Fresnel Effect, System Performance, Required Antenna Power, Power Budgets and other exotic stuff.
Fresnel Effects	Line-of-Sight (LoS) is not enough. An overview of Fresnel Zones and their effects on radio links.
Free Stuff	Defines the unlicensed frequencies for a number of countries
FHSS vs DSSS	Our unbiased (!!) overview of the two competing technologies.
Alphabet Soup	What with 802.11a, MIMO and DQPSK modulation you can get a real sore head with wireless terminolgy. Here a list in case you thought you had 'em all.
802.11 MAC	The media Access Control layer. CMSA/CA and all that jazz
