Binding a 4G modem router to a base station
Currently, this feature is implemented using a specific CLI (command-line interface) command for 4G routers.
Use the interface UsbLte0 mobile lte lock command to set the binding to a base station with EARFCN (E-UTRA Absolute Radio Frequency Channel Number) and PCI (Physical Cell ID) parameters.
The full syntax of the command is:
(config)> interface UsbLte0 mobile lte lock earfcn <earfcn-value> [pci <pci-value>]
where <earfcn-value> is the channel number indicating the carrier frequency at which the cell operates in the LTE network. It can take values between 1 and 68585 inclusive;
and <pci-value> is the Physical Cell ID. It can take values from 0 to 503 inclusive.
For example:
(config)> interface UsbLte0 mobile lte lock earfcn 123 pci 456
Mobile::Interface: LTE cell lock is set.To deactivate the binding, use the command:
(config)> interface UsbLte0 no mobile lte lock
Mobile::Interface: "UsbLte0": all LTE cells are unlocked.Use this command to save the setting:
(config)> system configuration saveNote
If binding is configured in a model with frequency aggregation, e.g. Hero 4G+ (KN-2311), the connection is fixed at the user-selected carrier as anchor frequency, and the additional frequency is connected to the aggregation automatically. The selection and connection of the additional frequency are made on the controller side of the mobile operator.
