LTE(4G) Lock Management
PCI Lock Click the switch button (to the right) to enable PCI (Physical Cell Identifier) Lock on base
stations when the Zyxel Device has 4G LTE connections. Physical Cell ID (PCI) is an
identifier for a cell, namely a cellular base station. PCI and Radio Frequency Channel
Number (RFCN) are combined to specify the base station.
Add New Rule Click to add a new cellular lock rule.
Physical Cell ID Enter the PCI number (0 – 504) of the base station to which you want the Zyxel Device to
connect.
RFCN Enter the RFCN (Radio Frequency Channel Number) for the LTE frequency of the
specified PCI (1 – 65535).
