Wireless system integrator bridging the digital divide



The City of Aurora is a Home Rule Municipality located in Arapahoe, Adams, and Douglas counties, Colorado. Aurora lies immediately east of Denver. It is one of the principal cities of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area and a major city of the Front Range Urban Corridor.

The City trusts Castle Rock Microwave to help them overcome their wireless connectivity challenges. As a result, they turned to CRM when they were looking to upgrade connectivity at several community locations in late 2020.

Castle Rock Microwave suggested wireless solutions from Cambium Networks in 60 and 80GHz. These millimeter wave frequencies are ideal for achieving fiber-like speeds at a fraction of the cost of building new fiber infrastructure.

We recommended the PTP850E for 80GHz and cnWave v5000 and v3000 for 60GHz. The PTP850E is an ultrahigh capacity, all-outdoor backhaul that delivers up to 20 Gbps capacity. The cnWave uses Terragraph, Facebook’s new terrestrial connectivity technology.

Terragraph opens up a new way to use the large amounts of unlicensed spectrum available in the 60 GHz millimeter Wave band, using a mesh architecture that can be used for many FWA, backhaul, smart cities and IoT use cases. With the increase in demand for gigabit connectivity and the availability of commercial equipment, Terragraph has become a hot technology, with the first large commercial deployments expected in 2021.
