<div>Hello all,</div>
<div>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.</div>
<div>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
</div>
<div>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? </div>
