LTE Modem LB1120 and LB1121 - Brick walls or surfaces - Concrete walls or surfaces For information about wall-mounting the modem, see Wall-Mount the Modem on page 93. Optional External Antenna You can purchase an external multiple input, multiple output (MIMO) antenna for the modem to extend the mobile broadband signal range indoors or in fringe network areas. The external antenna plugs into the two antenna connectors on the modem to boost speeds and extend coverage in buildings or vehicles, or in remote sites where network coverage is sparse. You could, for example, attach the external antenna on a window with a suction cup. Introduction and Hardware Overview 14
