SYSTEMS AND METHODS FOR SPLITTING CELLS IN A NETWORK FOR INTERNET OF THINGS (IOT)
Systems and methods for splitting cells in a network of Internet of Things (IOT) may evaluate a network metric such as receives signal strength indicator (RSSI) for end devices to determine a general network activity level. When the network metric falls below a predetermined threshold, the cell splitting controller may cause the cell to split in such a manner as to offload some portion of the end devices on an adjacent gateway and/or change frequencies to reduce the likelihood of collision. By splitting cells in this fashion, the density of end devices served by a single gateway is reduced, fewer collisions occur statistically, and the user experience may be improved.
1 . A cell split controller comprising:
an output configured to be coupled to a network connection; and
a control circuit coupled to the output, the control circuit configured to:
determine that a received signal strength indicator (RSSI) of an end device being served by a first gateway has fallen below a threshold;
order the end device to switch to a new channel set of a neighboring gateway;
check a new RSSI for the end device through the neighboring gateway; and
command the end device to switch back to an original channel set of the first gateway if the new RSSI is weaker than the received RSSI.
2 . The cell split controller of claim 1 , wherein the control circuit is further configured to compare the new RSSI to the received RSSI.
3 . The cell split controller of claim 1 , wherein the first gateway comprises a Long Range (LoRa) gateway.
4 . The cell split controller of claim 1 , wherein the control circuit is integrated into a LoRa server.
5 . The cell split controller of claim 1 , wherein the output is configured to be coupled to a software defined area network (SDAN).
6 . The cell split controller of claim 1 , wherein the control circuit is configured to command LoRa end devices.
7 . A cell split controller comprising:
an output configured to be coupled to a network connection; and
a control circuit coupled to the output, the control circuit configured to:
determine a second gateway is installed proximate a first gateway serving a plurality of end devices;
assign a subset of the plurality of end devices to the second gateway; and
assign a second channel set to the second gateway different than a first channel set assigned to the first gateway.
8 . The cell split controller of claim 7 , wherein the control circuit is further configured to order the subset of the plurality of end devices to use the second channel set.
9 . The cell split controller of claim 7 , wherein the output is configured to couple to a Long Range (LoRa) server.
10 . The cell split controller of claim 7 , wherein the control circuit is integrated into a LoRa server.
