What is NEMs?
NEMs (Network Equipment Manufacturers) are companies that design, manufacture, and sell the hardware and software infrastructure used by mobile network operators to build and operate their networks. In the 5G era, major NEMs include Ericsson, Nokia, Huawei, Samsung, and ZTE for RAN and core equipment, with emerging Open RAN vendors like Mavenir, Parallel Wireless, and Fujitsu providing disaggregated alternatives. NEMs are central to the 5G ecosystem, driving standardization, innovation, and deployment.
How Does NEMs Work?
NEMs supply the complete range of network equipment: radio units and massive MIMO antennas (RU), baseband units / distributed units / centralised units (BBU/DU/CU), core network elements (AMF, SMF, UPF), transport equipment (routers, switches, DWDM systems), and network management and orchestration platforms (OSS/BSS). In the Open RAN era, the traditional NEM business model — where a single vendor supplies the entire end-to-end RAN — is being disrupted by disaggregation, allowing operators to mix components from different vendors. NEMs are also expanding into system integration, managed services, and cloud-native network solutions.
Use Cases
