Reliable, high-capacity, point-to-point wireless broadband for the most difficult real-world situations.

Cambium Networks leads the industry in spectral efficiency and performance with the Point-to-Point (PTP) 650 wireless backhaul. With up to 450 Mbps aggregate throughput in a 45 MHz channel, and operating from 4.9 to 6.05 GHz, PTP 650 systems let you reliably and securely handle today’s needs with scalability to meet future requirements.

Dynamic Spectrum OptimizationTM (DSO) is a unique capability offered by Cambium Networks that enables a system to automatically sample and change channels to avoid interference to optimize link performance without affecting link service. Full details on DSO are in our White Paper.

PTP 650 PERFORMANCE GUARANTEE – The PTP 650 is the highest performing, most reliable sub-6 GHz PTP radio on the market. Cambium Networks stands behind this claim by offering your money back if you find something that works better. Customers can deploy a PTP 650 link with confidence that it will be the best performing, most reliable product they can find. If proven otherwise, they can receive a full refund.
