The following table shows the RF status indicated by WWAN_LED#.
Table 23: Network Status Indications of WWAN_LED#
4.5.4. WAKE_ON_WAN#
The WAKE_ON_WAN# is an open drain pin, which requires a pull-up resistor on the host. When a URC
returns, a 1 s low level pulse signal will be outputted to wake up the host. The module operation status
indicated by WAKE_ON_WAN# is shown as below.
