My ISP (Asahinet) had a special offer on Wimax, > hence my initial interest. AsahiNet very kindly loaned me a Wimax device (Uroad SS10) for a few days which I've just returned. Findings: - It is somewhat faster than my existing HSDPA-based Emobile dongle (approx 500KB/s vs 450KB/s downloads, tested using a server located in Tokyo; uploads much faster - approx 350KB/s vs 75KB/s) - WiMax signal at home is "orange" (i.e. middling) despite being (just) within the 23ku and having excellent conditions for the reception of wireless signals of all kinds. The signal improves to "green" closer to the local station; I didn't notice much difference in speed between "green" and "orange" - WiMax on the move in an above-ground train within Tokyo was fine - WiMax signal underground is very hit-and-miss; on the Tozai Line between Takadanobaba and IIdabashi, signal was available in the station and apparently sometimes between stations, but not at all within the underground part of Iidabashi Station or any of the Yurakacho line towards the Ginza area; also not in Meiji Jingumae station - The Wimax wifi device does not seem to work so well with either of my MacBook Pros in its default settings.; doing a simple speed test (scp of a large-ish file from the above mentioned server), I get a maximum download speed of around 65KB/s; no matter what location I try from. On an old netbook running Linux I got around 500KB/s. I've never had any wireless issues with the Macs before; changing the SS10's wireless mode to "11g only" (default: "11b/g/n mixed") seemed to resolve the problem. - I didn't get a chance to test it outside the 23ku area, but it wouldn't surprise me if the signal get spottier the further away one gets from urban areas Conclusion: WiMax is faster than Emobile HSDPA, especially for uploads, but the difference is not all that mindboggling. Signal coverage is OK, but it's been easy enough to find places where it is not available; in all cases Emobile did work. As I've hardly had any problems with Emobile reception (only place outside of actual tunnels I recall it not working recently is on a bus somewhere above Hakone), I'll stick with Emobile HDSPA for now, and maybe look into some sort of LTE option. YMMV. Anyway thanks again to Asahinet for the loan of the Wimax device, much appreciated. Ian Barwick
