It has become a bit silent around WiMAX in the past year or so with Clearwire being the only major network operator deploying the technology and making the news. WiMAX is also deployed in South Korea in the form of WiBro and some smaller networks exist elsewhere. What I didn't know so far was that Japan also has a WiMAX network on here. Here's a picture I've taken on a recent visit to Tokyo in an electronics store that sold WiMAX 3G dongles and notebooks with built in WiMAX cards. The main argument: The theoretical peak data rates are faster than those of the HSPA networks of the competitors. I wonder if that matters in practice?
