1. Introduction
H808G the advertising sender can send advertising info. to cell phone (GSM/DCS/TD-CDMA/WDMA)without charge.The coverage area is within 1-100m.When the cell phone holder enters into the covered area,the unit can intercept the IMSI code and send SMS automatically.No retransmit to the same IMSI code to avoid disturbance to the customer for repeating SMS.
Component: BPU+ CCU + Client ( computer)
