Case Study: City of San Diego transforms mission-critical communications with Nokia's IP/MPLS network

The City of San Diego upgrades its critical communications infrastructure using IP/MPLS and packet microwave technology, creating a next-generation public safety communications system

The City of San Diego faced the challenge of an aging public safety communications network that was nearing end-of-life and lacked the capacity for modern, bandwidth-intensive applications like video. This obsolete infrastructure could not easily scale or incorporate new technologies, and the city needed to improve reliability, reduce costs, and gain flexibility for future agency collaborations. To address this, they partnered with vendor Nokia to deploy a solution based on IP/MPLS and packet microwave technology.

Nokia implemented a new, shared IP/MPLS backhaul network using its 7705 SAR, 7210 SAS, and 7750 SR routers, along with its Wavence microwave solution. This created a highly resilient and secure system with deterministic quality of service (QoS) to prioritize critical traffic. The results included a significantly increased network capacity, a reduced total cost of ownership (TCO) through unified management, and a future-proof foundation ready for 10 Gb/s speeds and advanced applications like LTE, ultimately strengthening public safety and city services.
