Product Description

The SMG641 consolidates four 5G Sub-6 feeds, one Wi-Fi 6E/7 feed and active GNSS for connected vehicles, cabinets and industrial IoT equipment. The six-cable layout supports 4×4 cellular MIMO while preserving a dedicated Wi-Fi path.

Cellular coverage runs from 617 MHz to 7.2 GHz, and the Wi-Fi element covers 2.4–2.5 GHz plus 4.9–7.2 GHz. Positioning can be configured for standard GNSS, GPS only or optional tri-band L1/L2/L5 reception.

Ideal applications:

  • Connected vehicles
  • Roadside and utility cabinets
  • Industrial IoT gateways

Example Model Configurations: SMG641-7C7C2C-B-12, SMT641-7C7C2C-B-12
