Cambium 5781BH20 PTP 230 5.7GHz 50Mbps Point-to-Point Backhaul

The Cambium Networks PTP 230 (part number 5781BH20) is an integrated point-to-point wireless backhaul radio operating in the 5.7 GHz band. Built on OFDM technology, it delivers Ethernet throughput of up to 50 Mbps with AES encryption support, making it a capable solution for organizations requiring secure, long-range broadband connectivity. The platform supports both line-of-sight and near-line-of-sight deployments, and with optional passive antenna accessories extends its operational range substantially — up to 18 miles with a passive LENS and up to 80 miles with a reflector. GPS synchronization capability enables radio collocation with reduced self-interference, a critical advantage in dense tower and rooftop infrastructure environments. The PTP 230 is well suited for wireless backhaul networks, broadband residential and business access, video streaming, and VoIP communications.

Key features & benefits

• 5.7 GHz Integrated Radio Platform — The PTP 230 integrates its radio and antenna into a single unit operating in the 5.7 GHz band, simplifying installation and reducing the number of external components required at the tower or rooftop site.
• OFDM Wireless Technology — Orthogonal Frequency Division Multiplexing provides robust performance across both line-of-sight and near-line-of-sight paths, improving resilience against multipath interference in challenging deployment environments.
• AES Encryption Support — Built-in AES encryption capability protects backhaul traffic in transit, supporting security-conscious deployments in enterprise, municipal, and carrier applications.
• Up to 50 Mbps Ethernet Throughput — With Ethernet data rates reaching up to 50 Mbps, the PTP 230 provides meaningful capacity for broadband access, video streaming, and VoIP services across a single wireless link.
• Extended Range with Passive Antenna Accessories — Operational range extends to up to 18 miles (29 km) with a compatible passive LENS, and up to 80 miles (128.7 km) with a reflector, enabling connectivity across geographic distances that would be impractical for wired infrastructure.
• GPS Synchronization Capable — When paired with a compatible CMM or Universal GPS module, the PTP 230 supports GPS-based synchronization, enabling radio collocation with significantly reduced self-interference — a practical advantage for multi-link tower deployments.
• LOS and nLOS Deployment Flexibility — Support for both line-of-sight and near-line-of-sight operation expands the range of viable deployment scenarios, accommodating real-world terrain and obstructions that a strictly LOS-only platform could not address.
