Coffee, Coffee, Coffee
In about a week, I had an omnidirectional antenna installed on the
roof, and 25 feet of LMR-200 running down to our access point. Why
did I use 25 feet of cable that loses almost 17db of signal every
hundred feet? And why did I use an omni, when a tight sector or patch
antenna would have made more sense? Because in early 2000, without
any prior background in radio, I went with what our vendor had to
offer: a 25 foot run of so-called
"low-loss" microwave antenna cable,
and an expensive omnidirectional popsicle stick (after all, if Lucent
made the gear, it must be compatible with a
Lucent access point, right?).
Luckily for me, even with the high line loss, the omni managed to do
the job. That afternoon, I walked across the street, ordered an iced
mocha, and merrily typed out the confirmation email. As I hit
Ctrl-X Y, I was compelled to meditate on that
inevitable question, "What next?"
If it was possible to get a good signal about 1,500 feet from the AP,
how feasible would it be to provide wireless access to our local
employees? After all, many of our people live in the area and were
using dialup to access our network from home. Would it be possible to
provide a fast wireless connection to anyone who was within range?
Just how far could this technology be stretched?
