> 3.6.1 | Network Dependency of SLEEP Modes

> The power saving possibilities of SLEEP modes depend on the network the module is registered in. The paging timing cycle varies with the base station. The duration of a paging interval can be calculated from the following formula:
> t = 4.615 ms (TDMA frame duration) * 51 (number of frames) * DRX value.
> DRX (Discontinuous Reception) is a value from 2 to 9, resulting in paging intervals from
> 0.47-2.12 seconds. The DRX value of the base station is assigned by the network operator.
> In the pauses between listening to paging messages, the module resumes power saving, as shown in Figure 11.
> Figure 11: Power saving and paging
> The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed.
