First provider to provide a 4G network is sprint, its in the baltimore washington region. 4G wimax has a theoretical max through put of 100mbits per second. In comparison EV-DO rev A only has a theoretical throughput of 7mbps... so that means realistic speeds of wimax 4G could be around 10-15 mbps. I'd imagine wimax deployment will be mainly in urban and some suburban areas as it has range limits and requires more towers per square mile than GSM GPRS, or CDMA ev-do rev a. We are pretty much reaching the limits of realistic speeds in cellular networks with the given available spectrum. After february 2009, when the TVs switch over to digital, we'll have a ton of free spectrum, and then we'd be able to allocate wider channel bands and therefore more bandwidth.
