Benefits
Simple, flexible deployments
CMU simplifies your private wireless network deployment by combining all the essential mobile packet core functions either into a pre-integrated appliance comprised of two HP DL325 Gen11 rack-mounted servers that can fit easily into an IT cabinet or data center or as a containerized network function (CNF) deployed in a Red Hat OpenShift private cloud platform.
High availability
To support your business-critical communications you need a network that delivers high reliability and performance. CMU meets your high availability requirement with hot-standby stateful redundancy and supports edge network configurations for low-latency applications.
Comprehensive IIoT support
CMU helps your business put the Industrial IoT to work. It provides the scalability, performance and the 3GPP cellular IoT (CIoT) feature you need to support LTE-M and narrowband IoT (NB-IoT) applications efficiently and cost effectively.
How does Compact Mobility Unit work?
CMU is responsible for the core network functions of a private cellular network implemented in an integrated single appliance. The respective CMU architectures contain the following elements:
In LTE and 5G NSA architecture:
- Home Subscriber Server (HSS)
- Policy and Charging Rules Function (PCRF)
- Mobility Management Entity (MME)
- Serving Gateway (SGW)
- Packet Data Network Gateway (PGW)
In 5G SA architecture:
- Authentication Server Function (AUSF)
- Unified Data Management (UDM)
- Policy Control Function (PCF)
- Access and Mobility Function (AMF)
- Session Management Function (SMF)
- User Plane Function (UPF)
ICMU performs end point profile repository, identification and addressing via HSS and AUSF/UDM, policy control via PCRF and PCF, end point authentication, registration and mobility management via MME and AMF, routing, packet forwarding and session management through S/P GW and UPF/SMF.
Customer success stories
Use case: Finland’s Posiva was the first company in the world to build a safe disposal facility for spent nuclear fuel. Its latest process innovation involves transporting waste through underground tunnels with remote-controlled vehicles and autonomous robots to keep human operators safe. This required a highly reliable network that could function nearly half a kilometer below the surface of the Earth.
Using Nokia Modular Private Wireless, Posiva now benefits from advanced automation for its underground nuclear waste disposal process, leveraging mission-critical connectivity powered by the latest private 5G technology. This allows Posiva to ensure maximum safety in its hazardous nuclear waste disposal process.
Results:
- Minimized human presence in a hazardous operational area to meet safety requirements
- Enhanced productivity and operational efficiency
- Improved brand, company reputation and trust
Use case: Brazilian electric power utility, Elektro, wanted to increase grid reliability and sought a robust solution to connect the necessary IoT devices to enable grid automation.
Nokia's MPW solution has allowed Elektro to connect 78000 smart meters, 1300 load balancers and 850 concentrators leveraging nationwide private wireless network coverage.
Results: Elektro implemented grid monitoring to prevent illegal tapping and to increase grid reliability by up to 50% reducing revenue leakage by up to 80%.
Use case: Sempra, a leading US developer of renewable energy, wanted to connect sensors to monitor data and the health of wind turbine pitch mechanisms and assembly.
Leveraging the Nokia CBRS-based MPW solution Sempra now benefits from reliable connectivity across the 40 square miles of its 75MWh windfarm allowing the company to implement predictive maintenance of wind turbines.
Results: Sempra now has access to an efficient early warning system that allows it to perform predictive maintenance and save up to 90% of effort associated with turbine pitch assembly repair.
