Nokia has expanded its mobile fronthaul solution with new 1830 Versatile WDM Module (VWM) optical platforms, allowing operators to accelerate the deployment of centralized RAN architectures to satisfy the growing consumer demand for streaming video and downloading high-definition movies on mobile devices, as well as traffic demand from IoT-connected objects.
Operators can meet surging data traffic on their networks and offer consumers higher-speed mobile broadband services profitably by moving to a centralized RAN architecture. In centralized RAN architectures, baseband processing is separated from RF (radio frequency) equipment such as remote radio heads (RRHs) and run in a single location, allowing faster mobile broadband, increased capacity and lower operating costs.
According to Nokia, the adoption of centralized RAN has been hindered by an inability to deploy fronthaul networks in a cost-effective, easy to operate and scalable way, with high enough performance to quickly transfer massive amounts of traffic between the remote radio heads and centralized baseband equipment. .
