The municipal Wi-Fi market that started in 2006 experienced a downfall in the summer of 2007. Multiple cities pulled out of planned projects rather than accept anchor tenancy options even as a Forrester Research report warned that consumer use alone won't pay for a muni Wi-Fi network. Much of that criticism is the result of overblown expectations and, in some cases, poor planning by municipal officials. The biggest problem with in-home usage isn't with the Wi-Fi networks themselves but with the relatively low power of the Wi-Fi devices built into laptops and PC. Laptops that come with 802.11 functionality tend to operate at 30 to 50 milliwatts of power, which may not be enough to connect to an outdoor Wi-Fi antenna. EarthLink addresses the problem by making a customer premises device available that includes a 200 milliwatt antenna.
