SMWG-404 (Cellular, 2xWiFi, GNSS)

Cellular, 2×2 Wi-Fi, and GNSS Antenna

The SMWG-404 is a compact vehicle antenna that combines one cellular path, two independently cabled Wi-Fi paths for compatible 2×2 systems, and active GNSS.

Key Features

  • Expands local network capacity with two independently cabled Wi-Fi paths.
  • Keeps cellular backhaul separate from the Wi-Fi system.
  • Adds GNSS for navigation, tracking, and position-aware operations.
  • Consolidates four connections in one IP67-rated roof mount.

Product Description

2×2 Wi-Fi With Cellular Backhaul and GNSS.

The SMWG-404 brings two wireless paths, cellular service, and active GNSS together for mobile video, mesh, public-safety, and other multi-radio vehicle networks. Four independent cables preserve each equipment connection within one compact housing.

Flexible 2×2 Wi-Fi Connectivity: Both wireless elements cover common 2.4 GHz and 4.9–6.0 GHz ranges, while one broadband path also reaches 2.1–2.5 and 4.4–6.0 GHz.

Dedicated Cellular Backhaul: A separate cellular element covers 800–1250 and 1650–2700 MHz without consuming either Wi-Fi connection.

Active GNSS Positioning: GNSS adds navigation, tracking, and timing for position-aware mobile networks.

Four Protected Connections: The IP67-rated UV-resistant ASA housing consolidates all four paths and helps shield internal components from dust and water.

The SMWG-404 provides 2×2 Wi-Fi capacity, cellular backhaul, and GNSS through one compact vehicle mount.

Ideal Applications

  • Mobile video systems
  • Vehicle mesh networks
  • Public-safety gateways
  • 2×2 onboard Wi-Fi
  • Fleet navigation and tracking
