Main Differentiators

The PTP650L is available in asingle model covering 4.9 GHz to 6.05 GHz, offering high spectral efficiency and reliability in the most congested environments. This variety of bands and exceptional spectrum efficiency gives enterprises and service providers flexibility to choose the most effective solution for their network.

FLEXIBLE NON-LINE-OF-SIGHT (NLOS) SUPPORT is delivered by sub-6GHz spectrum featuring 2×2 MIMO OFDM, Fast Adaptive Modulation (AMOD), Dynamic Spectrum Optimization (DSO) and high spectral efficiency – 10 bps/Hz. With NLOS capabilities, service providers have a significant advantage in deploying capacity in the areas where most needed.

SIMPLE, FAST DEPLOYMENTS are supported by agile mounting options, a small form factor and low power consumption. PTP 650L simplifies the installation in all kinds of urban and rural environments. With built-in alignment tools and flexible management interfaces, service providers can plan, install, monitor and support their network while keeping costs low.

CARRIER-GRADE RELIABLE HARDWARE by Cambium Networks is constructed from high quality industrial components; it is out door-rated and rigorously tested to satisfy the most difficult environmental conditions. With greater than 40-year MTBF, our equipment standards are unsurpassed in industries requiring fixed wireless broadband.

PREDICTABLE CAPACITY assessment is provided by Cambium Networks’ LINK Planner tool. LINKPlanner enables network designers to accurately predict the capacity and availability of each link by selecting the end points on a map. LINKPlanner is a powerful planning, deployment and support tool.
