Municipal Wi-Fi arguably had a market window within which it had to get traction or lose out to cable companies and especially telcos. With EarthLink now backing out of the remaining deals it originally negotiated, that window could slam shut. That isn't to say there might not be some niches it could fill, but they will be smaller niches. The higher end part of the fully mobile market will be able to buy fourth generation mobile services, broadband based on 700 MHz spectrum, WiMAX and 3G broadband services. The tethered part of the market will simply find cable modem, Digital Subscriber Line and fiber to home services too attractive to ignore as well. The out of office portion of the market increasingly can use T-Mobile hotspots, hotel Wi-Fi and airport Wi-Fi.
Clearwire and satellite broadband are going to make more sense in most rural markets, though independent ISPs continue to offer basic tethered access using Wi-Fi technologies adapted for more focused line of sight deployment.
Wi-Fi had to get into place before WiMAX arrived, and it looks like it simply is too late to be a sizable mass market access opportunity. That isn't to say hotspots are not a business at all; simply that it is a niche.
That said, sizable niches do exist for providers of satellite broadband in some segments of the market. WildBlue, ViaSat, Gilat and HughesNet prove that the niche exists. And Spaceway might someday create additional niches in the smaller enterprise market as well. Wi-Fi, though perhaps not of the muni variety, might continue to provide such a niche.
