Power Save Mode (PSM)

Power Save Mode (PSM) is an essential feature in Narrowband IoT (NB-IoT) that helps to conserve battery power on IoT devices. PSM allows the devices to periodically enter a low-power state, minimizing their energy consumption when not actively transmitting data to the network.

Main Purpose of PSM

The main purpose of PSM is to decrease the data usage on your device and to extend battery life. The more often the device needs to connect to the internet, the more often it will check for new messages and updates, which consumes more battery power. PSM helps to reduce this energy consumption by allowing the device to periodically enter a sleep mode, during which it consumes minimal power.

PSM can be set on a per-device basis or globally for all devices. When a device enters PSM, it suspends all network activities and disconnects from the network until the next scheduled wake-up time. The device then wakes up, connects to the network, and checks for new messages or updates before entering the low-power state again.

Advantages of PSM

• Increased battery life: PSM helps to conserve battery power by allowing devices to enter low-power states when not actively transmitting data.

• Reduced network congestion: By reducing the frequency of data transmissions, PSM helps to reduce network congestion, freeing up network resources for other devices.

• Improved network efficiency: PSM allows IoT devices to communicate more efficiently with the network, reducing the overall power consumption of the network.

• Lower operating costs: By reducing energy consumption, PSM can help to lower the operating costs of IoT devices and extend their useful lifespan.

Power Save Mode (PSM) is a crucial feature in Narrowband IoT (NB-IoT) that helps to conserve battery power and improve network efficiency. By allowing IoT devices to periodically enter low-power states, PSM reduces energy consumption, network congestion, and operating costs, while extending the useful lifespan of IoT devices.
