1. Trial test of TD-LTE Integrated eNodeB in Guangzhou

From Dec 2012 to Jan 2013, China Mobile Research Institute, China Mobile Guangdong and ZTE Corporation finished the field trial of the TD-LTE Integrated Micro eNodeB. The test items investigate the effect of coverage enhancement of Micro eNB for coverage hole and hot spot in the urban area.

- For coverage hole: Significantly improve RSRP, SINR and throughput by the Integrated Micro eNodeB.

- For hot spot: Increase the throughput by 105 percent after introducing the Integrated Micro eNB. Different frequency deployment is better than using the same spectrum.
The test results demonstrate that TD-LTE Integrated Micro eNodeB can effectively improve the coverage for dead zone and increase the throughput for hot spot, and has the value to be commercialized in large-scale.

2. Trial test of Relay in Guangzhou

A. Completion of field trial of Relay:

In Feb 2013, CMCC and ZTE launched and finished the first trial test of preliminary commercial TD-LTE Relay product in Guangzhou, in order to explore and verify the advantages of Relay in the practical network.

B. Findings from Relay trial test:

· Features of current Relay product:

- Small size (<10L), no need for machine room, easy & flexible to deploy

- Support LOS /NLOS wireless backhaul

- No need for isolation between backhaul antenna and access antenna

· Benefits for the network from Relay deployment:

- Remove coverage hole in urban area without harm to cell throughput

- Improve indoor coverage for indoor users demanding high speed service

- Effective in the area where difficult/expensive to deploy wired backhaul
