My company One Ring Networks Inc. is a wireless ISP / carrier providing
VoIP services using asterisk to our customers in the metro Atlanta
area. Powering the radios has never been an issue. There is always
power within 30 to 50 meters of where you will want to mount a radio.
If you indeed are becoming a carrier, your biggest challenges will
almost always be securing the realestate where you intend for your radio
to live, gaining access to the riser core in the structure you plan to
provide service to, and lastly but not least the amount of money
required to turn up a customer. If you are planning to build a
substantial network using wifi, the technical list of issues that await
you are too long to list.
All that negativity being said, I've had a blast doing my part to help
build out our network.
Best of luck to you.

Hi there,
Well, looks like you are going to start a new telephony company ,-)
...When it is a quite dense populated area then there
should already be enough cables and operting providers ...
If you can find support by cable owners then you could indeed start to
setup some WiFi cells using their net for building up an own VPN. But
these cells will probably have just 100m radius w/o directional
antennas on the client side.
Therefore, roughly per "hotspot" you get an operation area of about
0,032 km^2 and you have about 1260 km °2 to cover (a 20km radius).
Guess how many hotspots you need and how many would overlap and create
interference ??? And what happens, when somebody in this area has an
own hotspot? How should all the hotspots be managed and the traffic
routed ???
Sorry, with 801.11a/b/g this is definitely not feasable at all.
Probably with bigger cells your idea could be realized using a UMTS
network ... In any case, you must have a BIG investment before that
can be done (and much money for radio licenses ...)
However, small 801.11a/b/g "islands" work out for customer access in
general with customer side directional antennas. But not with desktop
or mobile WiFi phones ...

this is not really an * question but it is somehow related, i am
trying to develop a working proposal for cheap and quick telephony
services using Voip running over *. By running a wireless network
(over 802.11 a/b/g devices), i plan to be able to reach customers
directly with eithe table top or handheld 802.11 sip enabled phones.
But the disadvantage is that how do i power each radio and back haul
the connection (this is to be able to cover at least 20KM radius of
densley populated region). During my research, i have fould out that
PoE switches exists and can be used to supply both data access and
power to the wifi radios, but these only run for 120meters tops b4
signall loss sets in
Is there a sort of high grade cat5 cable that can propagate signals
for up to 1Km? or does anyone have any idea that i could effectively
cover 20Km radius wing WiFi?
