BelFone Provides Subway Wireless Communication Solutions

Project Overview

In recent years, metro projects in major cities across the country have started one after another. Wireless communication equipment has also ushered in new development opportunities as an important tool for metro public security and firefighting users. 



A subway line is 27.8 km long, all underground, with 24 stations, one vehicle section and one parking lot. 


Needs Analysis

The urban subway is a highly concentrated area of human traffic, coupled with many staff in the subway station and the large area covered by communication needs. Therefore, higher technical requirements are put forward for on-site communication security. Considering the special characteristics of the subway environment, BelFone combines years of analysis of user needs in the public security and firefighting industries and its profound accumulation in the field of rail transit. To improve the efficiency of staff better and provide stable communication security, BelFone proposes the following construction requirements. 

1、Wireless communication can provide voice communication, short message and packet data communication between fixed staff and mobile staff inside the subway; the system is mainly group calling, and can also provide optional calling. 

2. Provide wireless means of communication between central dispatchers, station guards, vehicle section/parking lot guards, train drivers and mobile personnel of various departments according to operational needs. 

3、Priority queuing by department or personnel, when the service channel is fully occupied, calls with high priority level can interrupt calls with low priority level to ensure normal scheduling operations and to ensure command and dispatch in emergencies. 4. With the emergency call function, emergency calls have priority over all calls.
