Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

The SMG404 brings four Wi-Fi 6E/7 feeds and active GNSS to connected equipment that has limited enclosure space. Its 4-inch-diameter, 1.5-inch-high housing suits kiosks, cabinets and other IoT installations.

Wide Wi-Fi coverage: Each Wi-Fi path covers 2.4–2.5 GHz and 4.9–7.2 GHz with 5 dBi peak gain.

Positioning choices: Standard GNSS can be replaced with a GPS-only or optional tri-band L1/L2/L5 positioning configuration.

Ideal applications:

  • Roadside cabinets
  • Vending and kiosk systems
  • Industrial IoT enclosures

Example Model Configurations: SMG404-7C2C-B-12, SMT404-7C2C-B-12
