LTE antenna interfaces of a router include a MAIN interface (for the primary antenna) and a
DIV interface (for the secondary antenna). The primary and secondary antennas work
together. The primary antenna transmits and receives LTE signals, and the secondary antenna
helps improve the quality of received LTE signals.
