• Taiping cellular security questioned

  The Coast Guard Administration has failed to prevent service members garrisoned on Itu Aba Island (Taiping Island, 太平島) from using a Chinese cellular network to call home in a national security breach, the Taiwan Statebuilding Party said yesterday.

  The party received an anonymous tip that coast guard personnel on Itu Aba routinely connected to Chinese cell towers due to poor reception from Taiwanese networks, Taiwan Statebuilding Party Kaohsiung chapter executive Yang Pei-hua (楊佩樺) told a news conference in Taipei.

  Using the signal provided by a hostile power is a breach of national security, as China can find the location of devices connected to its networks and intercept communications between them, Yang said.

  Beijing has likely made its 4G network available to local Taiwanese devices to spy on the nation’s service members, she said.

  The party went public with the information not to start a blame game, but in the hope that the authorities would be prompted to address the vulnerability and improve cell service on the islet, she said.

  In 2018, the National Communications Commission (NCC) praised Chunghwa Telecom (中華電信) for successfully implementing a NT$30 million (US$938,262) project to extend its 4G coverage to Itu Aba after dispatching a mission of senior officials to tour the islet, said Lin Yi-ping (林意評), convener of the party’s Yilan County chapter.

  However, Chunghwa Telecom’s Web site indicated that only 2G services are available on Itu Aba, which does not line up with the pronouncements the commission made five years ago, Lin said.

  The use of “enemy cell towers” by Taiwan’s defenders of Itu Aba is a grave security breach that might reduce the nation’s creditability in the eyes of its allies, Taiwan Statebuilding Party Chairman Wang Hsing-huan (王興煥) said.

  The authorities must address the problem immediately or the country might as well lease Itu Aba to the US’ armed forces, which certainly would not compromise the security of the South China Sea for a cellphone signal, Wang said.

  The Coast Guard Administration and the commission separately said that the islet’s telecommunications satellite coverage was not satisfactory, but added that improvements would be be made soon.

  The coast guard said in a statement that safe and secure 4G telecommunications have been available to its bases on the Pratas Islands (Dongsha Islands, 東沙群島) and the Spratlys (Nansha Islands, 南沙群島), including Itu Aba, since the middle of 2017.

  A Mitsubishi Electric-made ST2 satellite is the main enabler of 4G phone and Internet services on those islands, it said.

  Internet, texting and image-sending speeds are slower for civilian users due to the need to prioritize secure military communications over limited satellite bandwidth, it said.

  The coast guard is working with the Ministry of Digital Affairs, the NCC and Chunghwa Telecom to improve telecommunication services at the bases, it added.

  NCC Vice Chairman Wong Po-tsung (翁柏宗) said that the ST-2 satellite’s 4G capabilities are mostly used to convey essential military and government communications, leaving limited bandwidth for other users.

  This means the network can handle voice calls efficiently, but not much more, Wong said, adding that China is known to operate towers within range of Itu Aba.

  The ministry has been working to secure telecom services from OneWeb and Starlink since August last year, he said, adding that a deal could be struck by the end of this year at the earliest.

  Itu Aba is too far from Taiwan proper for microwave boosters to be of use, leaving satellites the only viable option for high-speed Internet and phone services, he said.

  Beijing operates a large constellation of communications satellites, which gives it a significant edge in the reach and speed of its telecommunications, he said.
