## Abstract

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.

## Claims

### Claim 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 RSSI.

### Claim 2 (depends on 1)

The cell split controller of claim 1, wherein the control circuit is further configured to compare the new RSSI to the RSSI.

### Claim 3 (depends on 1)

The cell split controller of claim 1, wherein the first gateway comprises a Long Range (LoRa) gateway.

### Claim 4 (depends on 1)

The cell split controller of claim 1, wherein the control circuit is integrated into a LoRa server.

### Claim 5 (depends on 1)

The cell split controller of claim 1, wherein the output is configured to be coupled to a software defined area network (SDAN).

### Claim 6 (depends on 1)

The cell split controller of claim 1, wherein the control circuit is configured to command LoRa end devices.
