China Mobile Deploys Ericsson's Fiber Fronthaul Solution
STOCKHOLM -- China Mobile has collaborated with Ericsson (NASDAQ: ERIC) to adopt a wavelength division multiplexing (WDM) fiber fronthaul networking solution with the PAU 6000 product family for its first commercial deployment of a TD-LTE network, based on a centralized radio access network (C-RAN) architecture. The superior radio network performance provided by this system benefits China Mobile’s bottom line and provides its customers with a better mobile broadband experience. As a result, C-RAN and fiber fronthaul are attracting international attention with several operators conducting investigations and trials of these technologies.
Key to the successful C-RAN deployment of China Mobile’s TD-LTE C-RAN in the Qingdao Development Zone was the low capital and operational cost of the remote radio locations, which have only an outdoor antenna and the RRU [remote radio unit] without an air-conditioned cabinet. The PAU 6000 had to be as simple as ‘plug and play’ for the technicians; it had to be rugged for the outdoors and no bigger than the RRU while consuming very little power.
China Mobile’s C-RAN enables a lower total cost of ownership by centralizing baseband/main units (BBUs/MUs) into one location and through its existing fiber network and the PAU 6000, providing common public radio interface (CPRI) communication to its remote radio units located at a simplified radio site. The C-RAN based architecture with high-speed, low-latency CPRI fiber links enables tighter radio multipoint coordination for better LTE network utilization and reception.
