The National Broadcasting and Telecommunications Commission (NBTC) has warned that it will launch legal action against illegal community-radio operators who transmit signals that interfere with aeronautical radio-navigation and mobile communications.
From January till last month, the NBTC received 441 complaints from Aeronautical Radio of Thailand (AeroThai) regarding this issue, while last year it found more than 1,780 cases across the country.
NBTC commissioner Taweesak Ngamsanga said yesterday that such illegal radio transmissions could disrupt the communication between pilots and the officers at the flight-control and aeronautical radio-navigation centres in the nearby airports. That has an impact on aviation safety and threatens many lives.
The NBTC has already launched legal action against 18 illegal community-radio operators in Uttaradit, Nong Khai, Lampang, Nan, Khon Kaen, Maha Sarakham, Chiang Rai, Phrae, Udon Thani, Nonthaburi and Chon Buri.
"We will take immediate action against those who are operating [illegally] if we find them," Taweesak said.
In a separate issue, the NBTC also threatened to file a lawsuit against real-estate developers or building owners who have not registered with the watchdog to use radio frequency identification (RFID) readers at the entrance of condominiums and residential projects, because it found that radio signals used for RFID readers of some non-registered operators had disrupted communications on 900MHz-band mobile-phone services.
Given this disruption, mobile-phone users, particularly customers of the largest telecommunication operator Advanced Info Service, cannot be connected by either voice or data in an affected site.
After conducting a survey on this matter, the NBTC found at least 10 residential projects in Bangkok that caused such problems. Those include the U Delight condominium in Chatuchak, Metro Sky condominium at Intramara47, Park Venture Building on Phloenchit Road, and Sathorn Square Office Building on North Sathorn Road.
Under the Communication Radio Act BE 2498 (1995), those who violate this law regarding both cases will face five years in jail and a Bt100,000 fine if found guilty.
