Hello
I am exploring the radio module that can be used to communicate between the base and Rover gnss module with following specification.
1. Frequency range: 865 to 867MHz, unlicensed indian band.
2. Distance/ line of sight : 3-5km or more
3. Data rate: 58kbps or more
I would like to know about any part from ti that can support my specification mentioned above?

Regards
Balkis

    First I would advice you to estimate range with this tool: http://www.ti.com/tool/RF-RANGE-ESTIMATOR

    I believe you would require a very high output power to get the range you need with the wanted datarate. 

    You also have to consider the background noise level, I have seen that some locations in India has a very high noise level which will impact range. 

    In other words, is it physically possible to get the range you want and still comply with local radio regulations?
