Mobile signals to cover Beijing Subway lines 1 and 2 this year

07-05-2010 10:03 BJT

Mobile signals will reach Beijing Subway lines 1 and 2 by the end of this year. According to the plan, authorities involved will continue to encourage communications, radio and television operators to transmit mobile signals to the existing subway facilities by the end of this year.

Subway passengers cannot use their mobile phones

If you often use subway lines 1 or 2, you must be familiar with the inconvenience. Sometimes, you cannot continue your telephone conversation or cannot send out SMS messages due to a loss of signal. Currently, mobile signals at some of the subway stations along the two lines are extremely weak despite the fact that passengers at most of the stations can use their mobile phones normally. On July 1, mobile signals failed between the Guomao and Yonganli stations along line 1, and passengers’ mobile phones did not work normally when trains were on the move. According to Mr. Chen, his mobile phone works normally when he is in the stations but breaks down when he is on a moving subway train.

"One day, I received an important telephone call while on a subway train. When the train began to move, my mobile signal deteriorated sharply and I had to stop the conversation. Moreover, I even could not send SMS messages at that time."

Mobile signals will reach the existing subway facilities by the end of this year

On July 1, the Beijing Coordinating Team for IT Infrastructure Promotion published a plan for 2010 IT infrastructure promotion in Beijing. In order to send communications, radio, television signals as well as government information to all of the subway facilities, Beijing will formulate some necessary policies and standards by the end of this year. At the same time, relevant authorities will continue to mobilize communications, radio and television operators to send mobile signals to existing subway facilities by the end of this year. In the future, passengers using lines 1 and 2 will be able to make or receive phone calls and listen to the radio.

Communications equipment rooms have been built in all 39 subway stations

According to sources close to Beijing Subway Company, upgrading of the civil communications systems on lines 1 and 2 was launched before the Beijing Olympics, and communications equipment rooms have been built at all of the 39 subway stations along the two subway lines.

Subway passengers will have access to wireless internet service

Passengers will be able to make telephone calls and have access to wireless Internet in the future.

According to Beijing Subway Company, the Subway Line 5 has introduced a passenger information system (PSI). This is the world’s first WLAN wireless transmission technology-based passenger information system featuring vehicle to ground data transmission. It enables subway passengers to watch TV programs and sends video information about the train to the control center.

According to sources, in the future, passenger information systems will be installed on the Beijing Subway Line 2, 4, 10, 13, 6, 8 and 9.
