New high capacity fixed wireless broadband system from Cambium

A high capacity multipoint (HCMP) fixed wireless broadband system from Cambium Networks is now available in South Africa to support video surveillance and other mission-critical infrastructure backhaul applications.
The Cambium Networks PTP 670 system is targeted at service providers, public safety agencies and critical infrastructure operators – such as utilities and energy companies – which require high data throughputs within the confines of regulated radio frequency spectra.
According to Teresa Huysamen, Wireless Business Unit manager at Duxbury Networking – the local Cambium Networks distributor – many of these organisations have experienced significant growth in bandwidth and now demand more capacity as well as secure and reliable broadband connectivity.
“Based on Cambium’s widely-deployed non-line-of sight [NLOS] technology, PTP 670 wireless Ethernet bridges offer an array of features that meet these objectives — together with high-capacity multipoint deployment flexibility and one of the highest spectral efficiency levels in the industry,” she says.
“The PTP 670 system allows up to eight remote nodes to connect to a single master radio. This opens opportunities for new deployment models that enable rapid deployment, simplified planning and – by using the same hardware regardless of topology — a faster return on investment in equipment and operator training,” adds Huysamen.
The PTP 670, which provides up to 450 Mbps of throughput for video, data and voice applications, can be deployed in point-to-point (PTP) or HCMP configurations. It operates in the 4.9 GHz and 5 – 6.05 GHz frequency bands.
Split frequency operation allows separate transmit and receive frequencies. This feature mitigates the negative impact of situations where the interference environment is different at each end of the link.
In addition, Dynamic Spectrum Optimization, a capability offered by Cambium Networks, is designed to enable optimisation of link performance by automatically sampling and changing channels to avoid interference without affecting link service.
From a technical perspective, security is addressed via 128/256-bit Advanced Encryption Standard (AES) encryption, over-the-air rekeying (OTAR), Hyper Text Transfer Protocol Secure/ Transport Layer Security (HTTPS /TLS) and Simple Network Management Protocol Version-3 (SNMPv3) management, Remote Authentication Dial-In User Service (RADIUS) authentication and configurable password rules.
Two Gigabit Ethernet ports and a Small Form-factor Pluggable (SFP) port for an optional fibre interface are standard, together with an 802.3at Power over Ethernet (PoE) output port. Layer-2 bridge implementation supports symmetric and asymmetric time division duplex (TDD) operation, as well as the IEEE 1588v2 protocol and synchronous Ethernet precision timing and frequency.
