There’s been a lot of WiMAX chatter the last couple of months. For example, the major announcement in May of new financial backers for a US network (Comcast, Time Warner Cable, Google, Intel and Bright House). And yesterday came the much lower-profile, but still highly-important news of the first successful round of WiMAX certifications by the WiMAX Forum. Certification means interoperability, which is critical for any large-scale deployment.
