Open RAN is a hot topic in the telecom industry. The Radio Access Network (RAN) provides the critical technology to connect users, including mobile phones or enterprises, to the mobile network over radio waves. It also acts as a bridge to access all the key applications on the web.
Current RAN technology is provided as a hardware and software integrated platform. The ambition for Open RAN is to create a multi-supplier RAN solution that allows for the disaggregation between hardware and software with open interfaces and virtualisation, hosting software that controls and updates networks in the cloud. Benefits including supply chain diversity, solution flexibility, and new capabilities leading to increased competition and further innovation are expected.
The challenge in the 5G network is to build an infrastructure that can meet diverse service needs cost-effectively, which requires a revolution in network design and architecture. An Open RAN Remote Radio Unit (RRU) is used to convert radio signals sent to and from the antenna into a digital baseband signal, which can be connected to the DU over the O-RAN split 7-2x fronthaul interface. Evolving along with the RAN system, Remote Radio Unit (RRU) technology supporting multiple air interface protocols becomes essential of products.
Comba believes in the value of openness in mobile networks. As an active participant in the O-RAN Alliance and Telecom Infra Project (TIP), we work together with communication service providers and mobile network suppliers to create the foundation for openness, innovation and flexibility in radio access networks. Comba offers O-RAN Alliance standard compliant and TIP qualified high power multi-band, multi-RAT (Radio Access Technology) Remote Radio Unit (RRU) product portfolio for all types of RAN deployment scenarios. With the best performing, cost effective, highly reliable, software upgradable and flexible radio products, our future-proof OPEN RAN solution reduces total cost of ownership (TCO) for operators and neutral hosts.
