Technology: WiMAX and HSPA+ Speeds About Equal, in This Test

At least according to this test of the T-Mobile USA network and the Sprint 4G network in Philadelphia, Sprint's WiMAX network and T-Mobile's HSPA+ network delivered roughly similar download speeds, just shy of 3 Mbps on average.

These are real-world, average speeds, not "up to" numbers. By some estimates, 3 Mbps is easily twice as fast as the typical real-world speed with 3G, and faster than many home DSL connections.
