Abstract

The present disclosure is directed to methods and systems for providing a distributed radio communications network. Each of a first gateway and a second gateway may separately receive modulated signals comprising at least a portion of data from a first node of a plurality of geographically-dispersed nodes. The modulated signals may be wirelessly transmitted as radio frequency (RF) signals from the first node, the data gathered or generated by the first node at a first location. A server may receive the modulated signals from the first gateway and the second gateway. As configured by software-defined radio (SDR) software, the server may perform processing of the separately received modulated signals to recover the data. The processing may include demodulation of the modulated signals.

Claims

1. A system for providing a distributed communications network, the system comprising:

a first gateway receiving a first at least a portion of modulated signals of data wirelessly transmitted from a first node of a plurality of nodes, and performing sampling to generate first samples of the first at least a portion of the modulated signals;

a second gateway receiving a second at least a portion of the modulated signals of the data wirelessly transmitted from the first node, and performing sampling to generate second samples of the second at least a portion of the modulated signals; and

a server receiving the first samples from the first gateway and the second samples from the second gateway, the server configured by software-defined radio (SDR) software to combine the received first samples and second samples to recover the modulated signals of the data, and to demodulate the recovered modulated signals to recover the data.
