[Asterisk-Users] Voice Over WiFi

[Stagg Shelton]

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.
