Then do what I said. Get more bandwidth, install radios witrh their related
equipment in the right locations, advertize, do site surveys for responding
customers (and be prepared to turn some people down because they can't
receive your signal), install radios with their related equipment at
customer locations, handle the new injflux of tech support calls, and Bob's
your uncle.
Bandwidth is your first concern. Your little 1.5mbit pipe is certainly not
a useful amount of bandwidth for a wireless provider. If you won't provide
your customers with more than dialup speeds, they won't switch from dialup.
Even the slowest ADSL is 256kilobits. ISDN is 64 or 128 (actually a bit
more actual but that is off the topic). So, you could service half a dozen
customers at the slowest ADSL speeds and your T-1 is used up. Could you get
anyone to spend a few hundred on client-side equipment if they will be
limited to 30K? Not knowing your market, I can't say, but I would doubt
anyone would be knocking down your door.
So, without bandwidth, the cost of radio equipment, leasing antenna space in
a good location (unless you already own a high spot or two or three in your
area), and implementing actual customer connections is prohibative. Could
what you would charge half a dozen customers support your T-1, your staff,
your location expenses, etc? Could you even pay your janitor every month
from that?
Get fibre.
Go here for your antennas
http://www.fab-corp.com/ Consider Proxim for your
radios, or Cisco. Hire a Ham Radio operator or someone else who
understands radio technology (maybe a tech from your local AM/FM radio
station or somebody who has been a TV engineer) to advise you on antenna
locations and radio power (if you are staying in unliscensed band, there are
still a lot of regulations).
