This is a general question and i will welcome suggestions:

I just need to know :


1) what GSM RADIO (digital microwave Radio) can you recommend that has true broadband capability along with powerful propagation characteristics that ensure a reliable and robust network and covers great distances.
It should also offer high capacities, and a high degree of scalability, allowing the GSM company to meet current and future needs, and to expand capacity easily and cost-effectively as subscribership grows.

*emphasis is on longest distance such radio you recommend can cover.

2)for very long distances that microwave will not be useful, is there a solution yet to increase the limited broadband access or data/voice throughput of vsat systems to be as effective as microwave radios.
