Re: Can't call it a success yet

Good points, but the "300 foot" concept was absolutely just an estimate, and is really a diameter measure. You can push Wi-Fi using high-gain omni outdoor 1,000 feet or more without obstructions.
However the end user device would also need to be more powerful, wouldn't it?

EVDO isn't a better solution: too limited by spectrum (despite Wi-Fi's obvious spectrum limits, too). WiMax makes more sense, but both EVDO and WiMax are controlled by those that own the frequencies. That's what made Wi-Fi appealing.
Doesn't really matter in the end. This city service is still a paid service, not a free one. EVDO works in most any city and performs well indoors, and still offers 1xRTT in small/rural areas when traveling, which is still better than dialup. |

Basically either a high tx power and possibly high receiver sensitivity USB wifi adapter with 5 inch omni, or a router style box ment to be placed close to a window/outside wall again with big omni and high tx power. The router approach backhauls through wired ethernet to a customer's router or computer, or it creates a private wifi network for the customer inside their home whose internet comes through the public wifi network. |

I don't think so. The high-gain antenna should have the same Rx gain as the Tx gain.
EVDO's a fine solution, but won't offer the same bandwidth that WiFi is capable of offering. In a city like Minneapolis, I'm sure the towers don't cover a very large area, so they can obviously reuse parts of the spectrum. With any luck, I'll never be in Minneapolis again, but if I am I'll see how my Sprint Mobile Broadband performs. |
