After site survey by technician, Helios engineers decide to use 2 units of TD-LTE 2.6GHz 17dBm 
Digital ICS Pico Repeater to inject the signal from outdoor TD-LTE 2.6GHz Macro BTS into two 
separate areas / directions in the Retail Store, which it will be SISO solution only.

Before power on the Helios TD-LTE Digital ICS Pico Repeater, the overall TD-LTE signal coverage in

the Retail Store all are very weak, the RSRP is around -97dBm to -114dBm at different spots in the 

Retail Store, average download rate is around 6-12Mbps, average upload rate is around 0.76-3.63Mbps. 

Especially in the deepest area, the Manager Room, the RSRP is very weak as only -114dBm on there, 

high drop call rate, download rate is under 1Mbps, upload rate is around 6Mbps Afte power on the Helios 

TD-LTE Digital ICS Pico Repeater, the overall TD-LTE signal coverage in the Retail Store are improved 

very much, the RSRP is improved to around -85dBm, SNIR is improved to 14.5, download rate is improved 

to 22-25Mbps, upload rate is improved to 8Mbps, and improved much customer’s experience on mobile data 

service through 4G TD-LTE network.
