[CEATEC 2009] UQ, the sole Wimax carrier in Japan was showing this personal Wi-Fi hotspot device. It connects to the internet via WiMax, and serves as a wireless router for your personal devices. It’s like a MiFi, if you are familiar with that one. When WiMax is not available (in the subway and other “difficult” places), users can connect freely via Wi-Fi, thanks to the partnership between UQ and paid Wi-Fi providers. Coverage is not ubiquitous, but latency and speed should be better than 3.5G. If you wonder, it costs about $40 for a 30-day subscription and there’s no contract!
