Geoverse Provides Managed Services for Tucson CBRS Network
Wednesday, March 24, 2021 | Comments

Geoverse, a private cellular network operator, is the managed service partner for the Citizens Broadband Radio Network (CBRS) network being rolled out across the city of Tucson, Arizona.

The municipal network will enable remote learning and multiple smart city applications in the first phase and new use cases and applications in follow-on phases. The city’s private network is one of the largest municipal cellular deployments rolled out so far in the U.S.

The city deployed the Geoverse GeoCore evolved packet core (EPC) as the critical control element to manage the CBRS radio network infrastructure from JMA Wireless, the spectrum access service (SAS) from Google and the many user devices. Mobile devices and end points will be populated with a Geoverse subscriber identity management (SIM) card, enabling them to securely connect to the private network and utilize capabilities such as roaming if they travel off-net.

With the increasing requirement for remote learning, multiple school districts across Tucson faced an all too familiar problem. Many households did not have the resources to connect their school-age children. With limited resources and budgets, these school districts approached the city’s IT department to see how it could help address this digital divide.

Tucson Chief Information Officer (CIO) Collin Boyce embraced the challenge and quickly developed a strategic plan that started with a school and city-county partnership. Local municipal assets like city fiber and building rooftops and towers, combined with federal grant money, resulted in a viable plan to solve the student connectivity issue near term while also creating a network that could benefit the community elsewhere long-term.

A Wi-Fi approach was considered, but the required equipment, installation resources and related costs to connect the 31 neighborhoods, five school districts and almost 100,000 students proved problematic. Instead, the city evaluated LTE and CBRS, identified key advantages they offer, such as signal reach, performance, proven security and seamless mobility, and ultimately that became the foundation for the municipal solution.

“The resulting CBRS infrastructure footprint and related deployment resources required were significantly much more manageable and therefore more cost effective, which was significant in understanding the tight schedule and limited resources we were managing against,” Boyce said.

The municipal network offers high-performance wireless connectivity with download speeds of 50 Megabits per second (Mbps). In addition, the GeoCore Service platform allows for network slicing across the cellular network, resulting in multiple virtual networks that can each be dedicated to specific functions to help better manage city infrastructure domains.

Use cases include connecting the city’s network of traffic lights, monitoring and managing its critical water systems, serving city parks and recreational spaces with public Wi-Fi, and connecting first responders. It will also be the platform to offer its city staff low-cost, high-performance internet service.

“This is a major deployment both in terms of its coverage area and in its support of use cases, underscoring again the value of what these highly capable networks can now do,” said Geoverse CEO Rod Nelson. “We’re pleased to partner with the city of Tucson on such a critical effort to keep their communities connected and their schools open. This is a model other cities are closely watching.”
