Product
Sigwell
Device:System
Vendor: China Mobile
Overview
To improve indoor coverage, China mobile has developed a product named sigwell. Sigwell enhance the signal of GSM/TD-SCDMA/TD-LTE by wireless backhaul simultaneously. It is a perfect solution for blind spots or weak coverage scenarios, such as underground garage, ground floor shops, and private residence. Coverage can be improved about 25dB, uplink throughput can be improved more than 100%, downlink throughput can be improved significantly

|
synchronization scheme |
synchronize with donor eNodeB automatically, even the subframe configuration is changed. |
|
|
|
Lock the cell after the first synchronization. Will not reselect other cells unless the original cell level is lower than a given threshold. |
|
|
interference reduction |
|
|
|
|
power down the UL when no UE signal is detected, to avoid the UL interference with donor cell. |
|
|
self-excitation protection |
reduce the gain or power down when self-excitation is happened. |
