What is the range of license-free band frequencies
upto 1 kilometers?It's very urgent.....

There is NO licence-free band for a received range of 1km.
This is difficult to digest, as all power output constraints talk in terms of ERP which is a function of bandwidth and Frequency.
Besides, the main rule for Licence-free band operations is Low power Short Range devices without external antennae.
All specifications are in "funny" techno-legal language, less understood by lesser mortals. But the end result is the same: There is NO Licence-free band for a range of 1KM.
Meaning, the rules does not allow Free communication beyond 100m.

Buddy,why dont ya try using HAM radio frequency!!!!they are available for free
Be HaPpY !!!! U can GET me @ saurav@crazyengineers.com







well tat depends on the operator,i will definately let u know the frequency in my area!!!!
Be HaPpY !!!! U can GET me @ saurav@crazyengineers.com


Sorry, friend.....HAM (Amateur Radio) frequencies are NOT free.

hey docel,why dont ya take permission form the authorities,they provide access to frequencies for experimental purposes and wat more, u can get watever bandwidth u require,u just have to convince them!!!
Be HaPpY !!!! U can GET me @ saurav@crazyengineers.com


Huh????
Have you tried for that permission anytime??
