To date, no city has managed to make money with a municipal wireless network — but that hasn’t stopped new cities from trying. Those who started early are making the mistakes first, which is something those who follow can benefit from, but proponents insist Wi-Fi will ultimately gain in popularity. Current troubles for citywide networks include spotty coverage, fluctuating bandwidth, and poor indoor connections. Additional access points are usually needed, and dead spots continue to show up long after the initial installation is over. Early-installing cities like Tempe, AZ, hope that once the growing pains are over, they’ll come out ahead in the end.
