Line of Sight (LOS) Modem
The QMAe Line of Sight (LOS) Modem is an airborne, ruggedized software defined modem capable of operating in harsh military environments. It consists of a National Security Agency (NSA) certified Communications Security Module (CSM) and supporting interfacing circuitry packaged in a ¼ Airborne Transport Rack (ATR) chassis. The modem supports full duplex operation over L, S, C, and Ku frequency bands using tactical, VNW, IW, STD-CDL, and Bandwidth Efficient (BE-CDL) waveform options at data rates up to 44.73Mbps. It seamlessly interfaces with various external Radio Frequency Equipment (RFE)s and antenna equipment. The modem utilizes a Simple Network Management Protocol version 3 (SNMPv3) control interface for mission operation and a web-based GUI/KLV control interface for maintenance.
The QMAe LOS Modem, with its embedded Compact Multi-band Data Link (CMDLâ„¢ 2e), is based on a common product architecture. This architecture commonality assures interoperability between CMDL/CMDL 2 users and other L3Harris radio variants.
