The FCC initially held off on the license because of concerns that the signal for EMS’ new PDT-100 terminal unit would interfere with certain communications services using frequencies in the L-band portion of the radio spectrum. The agency had reserved the frequencies for an as yet unused aviation system, Gary Hebb, vice president of engineering and business for EMS’ Ottawa-based Satcom unit, said.
EMS’ system, which, began service in Canada in March 2000, is designed to operate exclusively on the MSAT 1 satellite owned by TMI Communications, Ottawa. EMS has sold 400 units in Canada, Jay McMillian, vice president of sales and marketing at the company’s Satcom division, told Spacenews.com.
While EMS initially will target the U.S. trucking industry, the applications for the technology are "virtually endless," McMillian said.
There are over 77 million large trucks in the United States, and less than 1 percent of those have data links to satellites, McMillian said. In addition, the technology can be applied to smaller delivery trucks, recreational boaters, trains and military vehicles, he said.
