Figure 30: e-DRX diagrammatic sketch
When module and the network negotiate stratum signaling in idle mode or sleep mode, extended mode
DRX can decrease the times of paging time window (PTW) and increase the cycle length. For this reason it
had reduced the times of DRX, and had reduced the frequency of DRX between module and the network.
So that can reduce power consumption for module.
If e-DRX is supported by the network, then it can be enabled by “AT+CEDRXS” command.
For details about “AT+CEDRXS”, please refer to Document [1]
5.4 Current Consumption
The current consumption is listed in the table below.
