The proprietary %REDMOB command is used to reduce LTE idle mode mobility, such as swapping between cells in stationary use cases. The command can be used according to the relaxed monitoring standard defined in 3GPP TS 36.304 Ch. 5.2.4.12 or in a Nordic-proprietary way.v1.3.x≥2
The 3GPP relaxed monitoring feature and the Nordic-proprietary reduced mobility feature are designed to reduce power consumption in stable radio conditions by limiting mobility and reducing measurements required for mobility. The actual power savings depend on the radio environment.
The main difference between the 3GPP relaxed monitoring feature and the Nordic-proprietary reduced mobility feature is that the 3GPP feature requires support from the network and the Nordic-proprietary feature does not.
