The Jingmen City Economic and Trade Commission of Hubei Province recently issued the "Notice on Strengthening the Coverage of Wireless Communication Signals of Elevators in the City", requiring all localities to accelerate the full coverage of wireless communication signals in elevator cars. All communication companies should verify the current signal coverage, actively strive for funds, increase the investment in elevator wireless communication signals, and ensure that Jingmen City will achieve full coverage of elevator wireless communication signals and most residential communities in major public places such as hospitals, shopping malls, and schools in 2019. Elevator signal coverage, full coverage of elevator wireless communication signals in 2020.
With the increasing number of high-rise buildings, the number of van elevators has increased, and many residents have been unable to leave the elevators for daily travel, and trapped elevators have occurred. If the elevator is stopped in the middle of the elevator and the personnel are trapped, the management personnel are not on the job, and the internal help fails. You need to call the mobile phone for help, and many elevator cars have weak or no signal.
It is understood that the wireless communication signal is transmitted in the wireless state, and the elevator will form a Faraday cage after the car door and the landing door are closed. The Faraday cage has the effect of electrostatic shielding, and also has a better shielding effect on the electromagnetic wave.
At the same time, since the position of the elevator is often located in the center of the building, the loss of the wall is also relatively large, and because of the tunneling effect of the elevator shaft itself, special coverage is required. The signal covers the elevator of the community, and often faces difficulties such as difficulty in entering the equipment and difficulty in coordination between the parties.
The General Office of the Hubei Provincial Government issued the “Implementation Opinions on Strengthening the Quality and Safety of Elevators” in July, requiring the Hubei Provincial Communications Administration, the Provincial Housing and Construction Department, the Provincial Quality Supervision Bureau and other units to gradually promote the full coverage of elevator car mobile phone signals. The elevator use unit is urged to provide assistance for the equipment installation and power supply access for communication operations.
The Jingmen Municipal Government of Hubei Province also issued the “Implementation Plan for Strengthening Elevator Quality and Safety Work in Jingmen City” to deploy the full coverage of elevator car mobile phone signals.
According to statistics, at present, there are more than 5,000 elevators in Jingmen City, Hubei Province. All localities are coordinating the communication companies to investigate the coverage of elevator signals in their jurisdictions, and formulate practical work plans for elevator wireless communication signal coverage.
