Fights over WiMax spectrum are slowing deployment of WiMax. The FCC, which manages the WiMax spectrum, has been renewing the existing spectrum, called EBS (Educational Broadband Services). The problem is that the EBS spectrum licenses, in many cases, belong to local educational institutions. Sprint wants to build a national WiMax network and thinks that the FCC should require the schools not using the spectrum to give it up.
To make things more confusing, Clearwire, another WiMax provider, has taken the route of simply negotiating licenses directly with the schools, who make some money from something many of them were not using.
The end result will be extensive overbuilding of WiMax networks, which raises costs and makes it more difficult for users to roam from network to network. Wireless broadband operators have never been able to work out roaming agreements the way the cellular industry did. Cellphones did not become popular until roaming agreements were in place, meaning your phone would work pretty much everywhere. Today, in most airports, as one example, there are often two to five WiFi providers, and paying for service on one operator's network does not let you roam on any other operator's network.
The bigger problem here is overbuilding. With several different companies all trying to build wireless broadband networks in a community, costs go up for all users because of duplication of infrastructure. The solution is for the community to build a multi-service network that allows multiple providers to use a single network. Users gain the benefits of true competition, and prices are lower because there is no duplication of infrastructure. The FCC could play a valuable role here by encouraging the development of multi-service networks, but instead, continues to try to put band-aids on outmoded policies.
