DOCOMO's Advanced C-RAN Delivers 240 Mbps using 35 MHz

NTT DOCOMO has achieved 240 Mbps downlink performance using 35MHz of bandwidth in a live field trial of Advanced C-RAN technology.

Advanced C-RAN leverages carrier aggregation (CA) technology to enable users to receive data simultaneously over small cells for localized coverage deployed in congested areas, and macro cells that provide wider area coverage. The carrier said Advanced C-RAN will prove especially useful for improving radio capacity and transmission speed in train stations, large-scale commercial facilities and other high-traffic areas.

The successful field trial paves the way for commercial deployment of the technology together with the launch of DOCOMO's LTE-Advanced network in March.

A previous verification trial last November used category-6 mobile devices capable of download speeds up to 300Mbps in the Yokosuka area of Kanagawa Prefecture, south of Tokyo.

"Advanced C-RAN represents an important contribution to the evolution of LTE and will be a key technology for the realization of 5G in the future," said Seizo Onoe, DOCOMO's Executive Vice President and Chief Technology Officer.
