WiFi is limited to unlicensed spectrum. That is a basic advantage but also a basic constraint. WiFi benefits from the 'viral adoption model'... the simple fact that that innovation is not bound by the need to be incorporated into a managed carrier network and users are free to deploy it. Typical cellular requires planned deployments and does not allow users to deploy beyond the confines of there buildings without prior arrangements. Clearwire, for example, could extend the WiMAX service model to allow users to deploy WiMAX as a local network similar to WiFi. The advantages would include availability of up to 120 MHz of spectrum which coulod translate into about 1 Gbps throughput. And the network would have higher security as a default - it would not be open to public use outside of the authorized users. WiMAX plus WiFi makes great sense because WiFi is widely available and uses similar technology,open IP protocols and is taken advantage of by common industry participants. But WiFi has a set of limitations in commercial networks.
