Satellite Phones Used at Inter-Korean Summit by Choi Ji-young South Korean delegates in Pyongyang used cellular phone to communicate with officials waiting in the South Korean capital of Seoul. Dacom announced on June 15 that South Korean authorities used 15 satellite mobile phones that make use of the low-orbit satellite, Globalstar, to communicate between Pyongyang and Seoul. Globalstar consists of 48 low-orbit satellites 1414 km above the earth. The satellites do not require any base stations to transmit signals. In 1994, business groups, including Loral Space and Telecommunications and Qualcom of the United States, and France Telecom, formed the Globalstar consortium and are now providing service to 38 nations. Dacom started its domestic service in April. The preparation of mobile phones for the Inter-Korean summit meeting via Globalstar was secretly arranged by Dacom and Chong Wa Dae for an entire month. Because the cellular phones contain a chip from Qualcomm, which is included as an item that is forbidden to enter an enemy state according to Department of Commerce authorities, the government officials obtained special permission through the Korean ambassador to the United States. Dacom said that Qualcomm and the Globalstar consortium of the U.S. agreed to actively support the Inter-Korean summit due to its historical significance. The biggest stumbling block for the South Korean delegation was in obtaining official permission from North Korea. The problem was resolved when President Kim Dae-jung explained that a means of emergency communication by state authorities was necessary. Dacom modified existing software to prevent interruptions that could occur while in the North, including wiretapping. Mobile telecommunication will be the latest trend in the near future according to Dacom, when more frequent communication takes place between the two Koreas. The company has already asked North Korean authorities through the South's Ministry of Information and Communication to allow selective servicing in the Stalinist state. Other facilities that enable communication between North and South Korea include a 35,000 km high International Maritime Satellite and the Mugunghwa Satellite, which uses a 1.8-meter parabola antenna. Users need a 60- to 70-cm antenna and a cellular phone as big as a suticase to facilitate the Internationl Maritime Satellite. As for the Mugunghwa Satellite, users must accurately match the angle of the antenna to the position of the satellite, while staying in the same location during communications.
