First Claim
Patent Images
1. A system to simulate part of a cellular network comprising:
- (a) means for simulating a plurality of MTs [SMTs];
(b) means for providing the functions of a first basestation [network access point/equivalent];
(c) means for simulating a communications forward link between said first basestation and each of said plurality of said SMTs through individual channels therebetween;
with both said simulating means are implemented on a generic, communications protocol-agnostic SDR hardware platform.
