Cal OES Selects Nokia to Upgrade Microwave Network
Tuesday, November 12, 2019 | Comments

The California Governor’s Office of Emergency Services (Cal OES) Public Safety Communications office selected Nokia to upgrade the California Public Safety Microwave Network (CAPSNET), which is operated by Cal OES Public Safety Communications and supports the communications needs of many key state and local government public-safety agencies.

The network upgrade is part of a solution to transform the current time division multiplexing (TDM) technology system to support more advanced IP-based networks. This will enable Cal OES to continue providing highly reliable and secure connectivity for first responders while enhancing the network to provide higher capacity and improved availability wherever needed, both now and into the future.

The upgrade is based on Nokia’s Wavence and 7705 Service Aggregation Router (SAR) portfolios and incorporates features specifically designed to address Cal OES’ unique needs. For the project, Nokia is replacing legacy hybrid microwave equipment with new packet-based technology while retaining full TDM interoperability. This approach will enable Cal OES to expand its bandwidth to support new IP-based applications while also increasing reliability and availability of the network, without impacting existing applications.

“For nearly half a century, CAPSNET has consistently provided dependable service to its agencies during disasters,” said Andy Cobb, area vice president, public safety, Nokia. “Nokia looks forward to working with Cal OES to modernize CAPSNET’s capabilities beyond what has historically been provided to what is now required to meet the public-safety community’s needs in the new digital age.”

Nokia Wavence is a packet-based platform that supports legacy TDM traffic and new Layer 2 and 3 services. Nokia’s solution to the state also includes the Microwave Packet Transceiver Plus (MPT-HLC Plus), the latest addition to the Wavence product line, which provides increased capacity by using 4096 quadrature amplitude modulation (QAM) and up to 7.5 dB more in system gain. Higher system gain can reduce the size of antennas required, lessen tower loading and extend the path distance, eliminating expensive repeater sites or just improving the availability of existing paths. The Cal OES network also includes Nokia’s Network Services Platform (NSP), enabling automation to assist in delivering transport services faster and dynamic assurance for operating the network with maximum performance and reliability.
