Hi Ya'All ;-)
I know this doesn't apply to everyone on the list, only those in the
local S.E. Texas vicinity, and/or near Houston. No matter, I still
consider this on topic. As Program Vice Chair M.P.E. on the GHRUG (BOD),
and because not many RUG's exists around the country anymore, we (BOD)
would gladly welcome everyone from outside the Houston area, as well as
our local members, to attend this GHRUG workshop coming up at the end of
next month. Read on, you DON'T want to miss out on this.
Denys Beauchemin of Beaudeux Wireless & Storage Consulting will be
conducting a Wireless Communication Workshop for the Greater Houston
Regional Users Group (GHRUG) of computing technology on April 29,
2004,8:00am to 5:00pm @ Avnet (located near Hwy 59 S and Beltway 8).
Denys' abstract is as follows:
Wireless Day
The Wireless revolution marches on at an ever-increasing rate.
Wireless Networks are sprouting up everywhere, but most people who put
up these networks do not really know how they work and how to set them
up properly. This one-day tutorial is aimed at people who want to know
more than just setting up an access point by following a wizard.
There will be equipment on hand to examine. There will also be a
handout. There will also be a live wireless network, which may or may
not be connected to the Internet.
The one-day tutorial will cover the following aspects of wireless
networks:
1. Introduction
a. Definition of Wireless LANs
b. Scope of the tutorial
2. RF Fundamentals
a. Behaviors: Propagation, Gain, Loss, Reflection, Refraction,
Scattering, Diffraction, Absorption.
