Wimax building penetration
WiMAX has 'failed miserably' • The Register
As owner of the Evo 3D and formerly the Evo 4G, I have to say the WiMax building penetration is terrible. I'm in an area that supposedly has.

The mean and standard deviations of indoor penetration loss vary with frequency , types Precise characterization of in-building penetration is therefore difficult.
Description:High latency is a problem for many internet applications, including the VoIP service that Buzz promoted to get customers. The lack of in-building penetration is a result of using high frequencies, which can carry lots of data but have shorter ranges and can't get into buildings, as anyone using a 3G network will testify. There has been a hope, in the industry, that WiMAX would magically solve these problems but radio frequency physics remain problematic. The industry was quick to blame Airspan , which provided the infrastructure to Buzz, but the supplier was equally quick to blame its customer, saying that cost-cutting had led to an ineffective network. Buzz Broadband opted to go with the less-expensive micro-cell base stations to reduce cost," Declan Byrne chief marketing officer at Airspan, said in an open letter. KT didn't try and sell VoIP services, and was covering an urban area where denser deployment of cells makes in-building penetration less of a problem, so indicating the kind of service WiMAX is more suited towards.
