  • Patent number: 10772059
    Abstract: The present disclosure is directed to methods and systems for processing packets over a communications network, including aspects of on demand network MIMO. A first gateway of a plurality of gateways may wirelessly receive a modulated signal from a first node, the modulated signal including a first packet. The first gateway may generate first samples corresponding to the first packet. The first gateway may decode the generated first samples to obtain decoded data. The first gateway may transmit the decoded data to a server. The server and/or the first gateway may determine, based on the decoded data, whether the first packet is successfully decoded at the first gateway. The server may obtain the generated first samples from the first gateway for decoding at the server, responsive to determining that the first packet is unsuccessfully decoded at the first gateway.
