City-Wide WiFi Planned In Minnesota
Add Chaska, Minnesota to the growing list of municipalities planning to offer Broadband Wireless Access through specialized WiFi systems. The USA Today article discusses how Tropos will blanked the suburb of Chaska with coverage for an estimated price of $18/mo. Some of the advantages Tropos brings to the solution are proprietary technologies that mitigate interference issues, and a methodology of partnering with the municipality. The latter strategy offers cheap access to city property and electricity for access point deployment, such as on street light standards. Contrast this with the community backlash common when new cellular towers are deployed. But despite the advantages of low cost equipment, free spectrum, and access to facilities, a Wide-area WiFi standard bucks the design characteristics of the technology. Wireless LAN, after all is a Local Area Network. While interference can be reliably managed within a home, enterprise, or warehouse, it is much more difficult to handle all the possible sources of interference out of doors. In many cases, we've heard of a WiFi-based WISP having their service knocked out of the air by a later-deployed 2.4GHz service (Motorola's "Canopy" system is know for punting 802.11 based systems). For chiefly this reason, I have my doubts about wide-area WiFi businesses (and I am quoted in the linked USA Today article). I think Tropos will get a run for its money from Wireless Wide Area Technologies such as UMTS TDD from IP Wireless, Flash-OFDM from Flarion, and others (not WiMAX, since that is neither mobile nor portable). Tropos' best bet is to leverage their experience working with municipal governments, but that's an advantage that doesn't scale well.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.
