Re: Can't call it a success yet
said by xenophon  :Since it won't go fully live until March, it's too early to call it a success. WiFi in not intended to work beyond 300' and is not the right solution for city-wide service. ... EVDO and WiMAX are much better solutions for city-wide access. It's designed for it. Cities may as well fund WiMAX providers, or at least offer telephone poles. 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.
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. |

However the end user device would also need to be more powerful, wouldn't it?

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. |

WiMax can also work in the 5.8 band which is unlicenced. Unfortunately when working in that band it will run into the same limitations as WiFi since it is an unlicenced band |

said by xenophon :However the end user device would also need to be more powerful, wouldn't it? Yep. Thats why something called "wireless bridges" are sold. 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. |
