3G/LTE Antenna Interface
3G/LTE antenna interfaces of a router include a primary antenna interface and a diversity
antenna interface. The primary antenna interface receives and transmits 3G/LTE signals, and
the diversity antenna interface helps improve quality of received 3G/LTE signals. Table 3-142
lists attributes of a 3G/LTE antenna interface.
