Commuters face more BTS Skytrain delays
Bangkok Transit System plc (BTSC) announced that passengers of its Skytrain services will face more delays today as an issue regarding wireless communication signals on its automated traffic control system persists.
BTSC announced on its Twitter page at 8.30am Wednesday that there were glitches in the wireless communications signals for the system that controls traffic on both the Silom and Sukhumvit routes.
The glitches had caused some trains to move at low speed and stop longer at stations, the Twitter message added.
BTSC said its wireless signals that is used for trains to communicate to each other and to the control system were interfered by the radio frequency of a mobile phone operator. The system uses both 2.4 GHz and 5GHz bandwidths.
The National Broadcasting and Telecommunications Commission will hold a meeting of BTSC and TOT Plc representatives on Wednesday to address the interference issue. TOT owns a 2,300 MHz radio bandwidth for its mobile phone operations.
