Course 120  Understanding Wireless
Understanding Wireless is a two-day intensive course designed for those needing to get up to speed, fill in the gaps and put in place a solid understanding of today's wireless technologies… and anyone wanting to improve their career- and productivity-enhancing knowledge base.
We'll review basic radio principles and frequency bands, then cover Wireless LANs in detail:
five chapters on Wi-LAN concepts, standards, equipment, deployment, configuration, performance and security.
We'll survey other wireless technologies, including LMDS, Bluetooth and satellite internet access,
then you will learn about mobile communications and cellular in detail: mobility concepts, handoffs, registration, first generation analog, second generation digital, and really understand what CDMA is, how it works, why it's called spread spectrum, and how it compares to TDMA/GSM and GPRS.
We'll finish off with the third generation of cellular, 3G, competing technologies cdma2000 1X and UMTS, data over 3G and applications: i-mode, SMS, wireless email, WAP, XML and the Wireless Web.
… and explain all of this in plain English.  We'll start at the beginning of the story, progress through key concepts in a logical order, and finish at the end. Our goal is to bust the buzzwords, cut through the jargon and doubletalk to put in place a clear, structured understanding of today's wireless communications.

2. Wi-LAN Standards
Wireless LAN technology is becoming ubiquitous - and has already started changing the way we work. From Starbucks to home to warships, wireless LANs have gained enough momentum that a detailed understanding of the concepts, technologies, deployment, performance and security issues is becoming a valuable knowledge asset.
We begin with an overview and comparison of the different standards: 802.11a, 802.11b and 802.11g.

3. Deploying Hotspots
Next, we turn to the practical: how to implement a Wireless LAN by deploying Access Points (APs) to create "hotspots". We'll understand the functions performed by many current home / small office Wireless LAN "router" products, including how they assign private IP addresses to stations, perform Network Address Translation (NAT) to allow Internet connection, and include Ethernet switches for hardwired connections.
Then we'll look at deploying a Wireless LAN in a larger office or meeting area, using multiple APs and assigning each a different channel. You'll understand channel allocation design, interference and location considerations. All of this is information you can put to immediate practical use.
