Cellular networks provide competitive infrastructure to the wireless solutions for machine-to-machine (M2M) applications, such as wireless automatic meter reading (AMR). Unlike mobile phones, the data modems are usually installed in metal cabinets, basement rooms, vehicle's dashboard, or elsewhere behind panels where external antennas are required for reliable communication.

COJOT M2M antennas are designed to support non-uniform meter and system environments. The antennas are ground plane independent, durable, and easy to install.
