Designed with Flexibility in mind

The mTenna CM is intended to be a family of multi-use, modular products that can be deployed in a variety of applications. Typically, the CM would consist of the antenna structure and control electronics, and in some cases the power amplifiers and low noise amplifiers. The CM package would be analogous to a square tile, and is expected to be 30-50 cm on each side and just 1.5-3 cm thick. The CM would be offered to terminal vendors who would add the customer-specific modem and related hardware. The first generation of the CM is expected to have separate transmit and receive panels. The terminal vendor can then mix and match panels as needed to deliver the required performance.

Applications

Applications of the CM are expected to include:

  • Commuter trains
  • Intercity trains
  • Commercial trucks
  • Automobiles
  • RVs
  • Buses
  • Recreational vessels
  • Small commercial vessels
  • Cruise ships
  • Merchant vessels
  • Ferries
  • Unattended sensors
  • Homes and small offices

The target specifications for the CM are shown in the table below.
