AIR H wireless internet service in Tokyo Area

[John]

Hi everyone,

Has anyone used the AIR H wireless internet service in the Tokyo area?
I am not able to have my own phone line at the place I'm living, so
I'm considering getting this service. It's a little expensive and I
think I have to sign a year contract, so I wanted to get some opinions
about it first. For example, how is the signal coverage (I will be
using it near Ota-ku, Meguro-ku), is there ever connection problems,
etc.

Thanks,
John
