WiMAX provider Clearwire has expanded its Silicon Valley network to cover the Google and Intel campuses. This development is a long time coming as the two tech behemoths are principal investors in Clearwire. Cisco is another partner and expects to have Clearwire coverage soon. Everyone else in the San Francisco Bay Area can expect the 4G service at some point in 2010.

The service is capable of up to 10 Mbps down, with an average of around 3-6 Mbps. That’s probably a few times faster than any 3G wireless data service you’ve used in the US. Leading up the public launch, select developers will be given free access, provided they live or work in the so called "Innovation Network" coverage area. They need only purchase a $50 USB modem. Certainly a good deal if you’re a developer who wants to work with WiMAX. So, how much would you pay for WiMAX service like this?
