SMWG-312 (Cellular, WiFi, GNSS)

LTE-U, Wi-Fi, and GNSS Surface-Mount Antenna


The SMWG-312 is a compact vehicle antenna with one wideband cellular/LTE-U path through 6 GHz, separate dual-band Wi-Fi, and active GNSS.

Key Features

  • Extends the cellular/LTE-U path across 694–960 and 1710–6000 MHz.
  • Keeps dual-band Wi-Fi available on a separate RF connection.
  • Adds active GNSS for navigation, tracking, and timing.
  • Consolidates three connections in one IP67-rated surface mount.

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

Product Description

Wideband Cellular Through 6 GHz. Wi-Fi and GNSS Included.

The SMWG-312 serves vehicle gateways that need a cellular or LTE-U connection extending beyond conventional LTE ranges. Separate Wi-Fi and GNSS elements keep local networking and positioning available within the same compact antenna.

Extended Cellular and LTE-U Coverage: The wideband element covers 694–960 and 1710–6000 MHz for compatible cellular, LTE-U, and higher-frequency radio equipment.

Independent Dual-Band Wi-Fi: A second element covers 2.4–2.5 and 4.9–6.0 GHz, preserving a dedicated local-network connection.

Active GNSS Positioning: The GNSS path supports navigation, tracking, and timing without another exterior antenna.

Compact Multi-Radio Protection: The IP67-rated UV-resistant ASA housing routes three independent connections through one vehicle mounting point.

The SMWG-312 combines an extended cellular/LTE-U path with independent Wi-Fi and GNSS for high-frequency mobile gateways.

Ideal Applications

  • LTE-U vehicle gateways
  • Wideband mobile-radio systems
  • Fleet and public-safety networks
  • Dual-band onboard Wi-Fi
  • Navigation and tracking equipment
