China Mobile and Ericsson Complete LTE-A TDD Trial in the 3.5GHz Band

China Mobile and Ericsson have actually effectively utilized the 3.4 3.6 GHz (3.5 GHz) frequency band for screening information speeds, movement and TDD provider aggregation. This LTE Advanced TDD trial, which was collectively performed in January 2015 in China, is making use of Ericsson’s equipment.

The initially stage of the trials was carried out at Ericsson’s laboratory in Beijing. Speeds of DL 223 Mbps were attained by utilizing provider aggregation(20 MHz@3.5 GHz band and 20 MHz@2.6 GHz band ), consequently verifying the capacity of 3.5 GHz TDD innovation to enhance mobile broadband ability.

Handover was likewise effectively carried out throughout the screening, therefore verifying the movement ability and possible efficiency reliability. The 2nd stage is the field trial which has actually been performed in February 2015 making use of China Mobile’s live mobile network and based upon Ericsson’s TDD 3.5 GHz radio devices.3.5 GHz: an essential band to satisfy the mobile web traffic development 3.5 GHz offers 200 MHz of spectrum and addresses more than 50 % of TDD licensees.

With the developing environment, 3.5 GHz has actually been acknowledged as a prospective worldwide balanced band for TDD and will certainly play an essential function in satisfying the traffic needs for the future and enhancing the user experience. Japan has actually just recently appointed 3.5 GHz(late 2014 ), and anticipate to deploy an industrial LTE-Advanced TDD network in 2016 in this band.” This TDD screening showed that the 3.5 GHz band can be effectively made use of both in stand-alone mode and in aggregation with existing office spectrum band to offer sophisticated mobile broadband services utilizing a TDD gain access to plan for high peak information rate applications to boost the user experience and operator’s competitiveness, “states Dr. Guangyi Liu, CTO of Wireless Department of China Mobile Research Institute.

This job has actually supplied a chance to collect necessary experience en routes that future multi-frequency networks might be enhanced from expense and efficiency viewpoints. Among the most satisfying outcomes of the initial step of this trial is the verification that the existing, lower-band network resources can additionally use 3.5 GHz as addition to the tradition network.
