A 16dB+ panel antenna and Ubiquiti Networks Bullet2HP radio, and a suitably high location, would shorten that distance for you very nicely. ;) From my own experience working on a community wireless project in St. Louis, the benefit of a 1Gbit/s fiber uplink (or several) would be that you could use newer 5GHz radios with MIMO features to build out >=50Mbit/s distribution for that uplink over a few square miles. So, 1Gbit/s could be parted out to 20 end users getting 50mbit/s each, and with an infrastructure cheaper than running fiber or some other wired medium directly to those 20 users.

Upvoted twice for UBNT. Downvoted once for math: 50mbps x 200 users = 10,000mbps Arithimetic aside, Ubiquiti is quickly changing the Wisp world. At Freenet, we switched from Canopy and upgraded our backhauls to Ubiquiti Airmax and saved money in the process. I am typing this now from a mesh node connected via a NanoStationM5! Given my experience with city-wide wireless in Lawrence, ubiquitous WiFi in KCK really needs to happen, IMHO.

  Oops, caffeine + haste = poor math. Fixed.

  Sadly, plenty of ISP's use that math. (Users * Bandwidth / 10) = uplink.

    I can't disagree too much, upload speeds are really disappointing. As one other poster pointed out, this can have a negative effect on entrepreneurs trying to bootstrap businesses from home. As for why upload speeds are awful, my experience has been that it is a trade-off that has been calculated by the ISP. But not in the way I suspected. Any link level device that uses a single (simplex) medium (wifi, fixed wireless, mobile wireless, cable modems, DSL modems, etc. as opposed to Ethernet, which is generally duplex) only has so much bandwidth available. At the WISP I worked for, we used to use Canopy 900mhz radios to provide fixed wireless service as well as backhaul for our city-wide mesh network. Since these radios only had ~3.3mbps aggregate bandwidth, we had to decide how to allocate it. In our case, we chose something like 5:1 download to upload ratio. This was a conscious choice about how best to use the available spectrum/bandwidth. I believe the same is true for cable/DSL media. Please feel free to correct me.
