Anybody here who can share their experiences with TATA WiMax connection?

In last month (July), i lodged almost 10-12 complaints and mid August, today i got a call from one of their dealer that we are getting rid of cables in your entire area (as we - TATA - got lots of complaint since few weeks). We offer FREE WiMax (no connection, hardware or any charge) - my all settings remain same except they put a small device on my terrace.

I had no other option and i said YES. They got it working within 2 hours and it works fine now.

What i want to know is that how is the others' experience with WiMax?

(their tower isnt too far from my house - may be just a km away)
