Cambium Networks ePMP 3000 4×4 MU-MIMO Sector Antenna

Overview:
The ePMP 3000 4×4 MU-MIMO Sector Antenna is designed for use with the ePMP 3000 access point system and delivers high-capacity, high-performance sector coverage in the 4.9–6.0 GHz band. This antenna is engineered to support multi-user MIMO operation, enabling simultaneous communication to multiple subscriber modules and greatly improving spectrum efficiency. It is optimized for fixed-wireless broadband networks requiring sectorised deployments with robust interference rejection and predictable coverage.

Key Features:

• Supports 4×4 MU-MIMO operation, enabling the sector to address two subscriber modules simultaneously and boosting effective throughput in the downlink.

• Frequency range from approximately 4.9 GHz to 5.97 GHz, offering flexibility for spectrum planning.

• Gain of around 17 dBi for strong signal focus and sector coverage.

• Azimuth 3 dB beamwidth of approximately 70° for typical 90° sector deployment; elevation 3 dB beamwidth around 6°, providing focused vertical confinement.

• Front-to-back (F/B) ratio of ~30 dB, helping isolate sectors for reuse and reducing co-sector interference.

• Polarisation: 2× horizontal & 2× vertical (dual vertical/horizontal) for optimal MU-MIMO performance.

• Designed for AB-AB channel reuse (two channels across four sectors) for efficient frequency reuse and spectrum economy.

• Rugged outdoor construction: weatherproof housing, UV-protected materials, suitable for outdoor tower/mast mounting.

• Integrated mounting hardware and antenna body designed for installation with the ePMP 3000 radio, simplifying deployment.
