The Wireless Monitoring Authority (WMO) of the Department of Telecommunications (DoT) has intensified the monitoring of mobile signal spillage in border areas, including Rajouri and Poonch in Jammu & Kashmir (J&K).

The exercise was conducted in June 2019 in coordination with the Intelligence Bureau. During the exercise, mobile signal spillage from Pakistan-based telecom operators was detected in Uri and Boniyar area of J&K, a DoT note stated.

As per the note, the WMO also detected source of interference reported by China through the International Telecom Union (ITU). China’s administration had reported unknown signals through ITU in the 406MHz frequency band  emerging from Korba area of Chhattisgarh. These signals were causing interference to EPIRB frequencies which operates through CISPAS SARSAT satellite system for ensuring safety of life at sea, the note said.

To search and detect the source of interference, WMO had deputed three teams from Raipur, Nagpur and Bhopal in Korba area. The teams have successfully identified the interfering signals emanating from locomotives of Indian Railways at Korba area and have submitted a report to the DoT for further action, the note stated.
