Unlimited wireless internet plans for Delhi/NCR area?

Hi, I'm moving to Delhi for six months and I was wondering if there are any ISPs offering unlimited wireless broadband plans.
I would really appreciate if anyone could provide the details.
Thanks!

Yes, there is this one provider, but I warn you its crap! Tikona...
You can see the reviews in this forum. I suggest that you opt for a 3G plan in your mobile. Why exactly do you need a wireless plan? Also try MTNL/BSNL WiMax.

The other options are USB baed..
1. TATA Photon
2. Reliance - 3G based
3. MTS
4. Airtel - 3G based
5. BSNL
6. Vodafone - 3G based
