5GHz point-to-point link targets IoT and 5G

By Nick Flaherty

Broadband wireless equipment maker InfiNet Wireless is launching a software defined radio system with what it claims is record-breaking spectral efficiency.

Quanta 5 is designed primarily for the small home and office market and small service providers to offer backhaul for Wi-Fi and 4G/LTE base stations as well as CCTV and video-surveillance infrastructures. It can also provide Internet access to remote locations.

A key element is mitigation of interference in noisy radio environments, using 14 modulation-coding schemes to dynamically select the most suitable Modulation and Coding Scheme (MCS) to ensure delivery of all packets transmitted, even in high-interference environments. This provides 450Mbit/s in a 40MHz channel via 800,000 packets per second. The latency is a maximum of 3ms.

“Our Quanta 5 solution is designed to address challenges such as limited spectrum availability, growing interference challenges and demands for yet more capacity as we see unprecedented growth in IoT applications and connected devices,” said Kamal Mokrani, Vice President at InfiNet. “This, combined with the move towards 5G, brings new challenges to the broadband infrastructure – and it is vital that service providers have the tools to keep pace with these technology innovations and deliver the fast and reliable connectivity required. Quanta 5 helps service providers do just that, providing a high-performance, cost-effective, easy-to-install and future-proof solution.”

A new design also allows additional features to be implemented remotely via a firmware upgrade, even for units already deployed in the field.
