Abstract
In one embodiment, a method includes: receiving, in a receiver of a gateway, from a wireless device a radio frequency (RF) signal including a packet and processing the RF signal to obtain a digital stream; detecting and synchronizing, in the gateway, the packet based at least in part on a preamble of the packet; decoding, in the gateway, a header of the packet to obtain information associated with the packet; demodulating, in the gateway, a data portion of the packet into soft information; and sending at least a portion of the decoded header and the soft information from the gateway to a server coupled to the gateway, to enable the packet to be decoded using the soft information.
Claims20
A method comprising:
- receiving, in a receiver of a gateway, from a wireless device a radio frequency (RF) signal comprising a packet and processing the RF signal to obtain a digital stream comprising the packet;
- detecting and synchronizing, in the gateway, the packet based at least in part on a preamble of the packet;
- decoding, in the gateway, a header of the packet to obtain information associated with the packet;
- demodulating, in the gateway, a data portion of the packet into soft information;
- and
- sending at least a portion of the decoded header and the soft information from the gateway to a server coupled to the gateway to enable the packet to be decoded using the soft information.
A method comprising:
- receiving, in a network server, soft information of a data portion of a packet from each of a plurality of gateways receiving the packet from a wireless device;
- recombining the soft information of the packet to obtain aggregated soft information of the packet;
- and
- decoding the data portion of the packet based on the aggregated soft information of the packet.
A system comprising:
- a plurality of gateways to receive packet communications from a plurality of wireless devices in a long range wireless network, each of the plurality of gateways comprising first hardware circuitry, first memory, and first storage, wherein each of the plurality of gateways is configured to:
- receive, from at least one of the plurality of wireless devices a radio frequency (RF) signal comprising a packet and process the RF signal to obtain a digital stream comprising the packet;
- decode a header of the packet to obtain information associated with the packet;
- demodulate a data portion of the packet into soft information;
- and
- send at least a portion of the decoded header and the soft information to at least one server;
- and
- the at least one server coupled to the plurality of gateways, wherein the at least one server comprises processing circuitry, second memory, and second storage, the at least one server configured to:
- receive the at least portion of the decoded header and the soft information from at least two of the plurality of gateways;
- recombine the soft information of the packet to obtain aggregated soft information;
- and
- decode the data portion of the packet based on the aggregated soft information of the packet.
