[F12_AR1220-Cellular0/0/0]modem reboot

Warning: The 3G/LTE module will reboot. Continue? [Y/N]:y

 

Root Cause: The 4G signal of the location where the client device is stored is weak. After the customer places the device on the window and restarts the 4G module, the signal can be received normally.

After I looked at the cause of the problem, I realized that the 4G signal of the location where the client device is stored is weak. After the customer places the device on the window and restarts the 4G module, the signal can be received normally. It's easy to ignore this, thank you for sharing, This post was last edited by Mark.hu at 2018-10-31 14:08.

Different from a traditional 3GPP network, an LTE network uses the single-layer architecture that combines radio network controller (RNC) nodes and NodeB nodes into E-UTRAN NodeB (eNodeB) nodes, as shown in Figure 1. The eNodeB nodes complete circuit switching on the base stations. This single-layer architecture simplifies the network, shortens the system delay, and reduces the costs in network construction and maintenance.
