[wsfii-discuss] Is ISM band 5.725 to 5.8 50 GHz free in India?

[Hitesh Shetty]

Hi Mahabir,
I have little to contribute to what Fred and Vikram have already said .
However in addition I would also like to add that the 5.7
GHz spectrum for outdoor use is not delicensed.
It can be used but only for indoor  use.
The license for 5.7 GHz for outdoor use costs a lot of
money running into lakhs of Indian rupees.
Many ISP's are linking their remote sites wirelessly by
using
Properietary systems like Canopy , by Motorola.
It uses OFDM and gives very accepted performance even
in harsh weather conditions.
Canopy still uses 2.4 GHz but needs tweaking for
integration with traditional 802.11 b/g n/w, maybe you
could consider this for use , since its a better alternative
for long distance , effective wireless links without
interference from other devices using the 2.4 GHz ISM
band.

I hope you find the information useful.

Regards
Hitesh Shetty
