The Ellipso™ user terminal is very similar in form and operation to those used for cellular telephony. There are three primary types of Ellipso™ user terminals: handheld, mobile, and fixed. Handheld Ellipso™ terminals resemble present cellular pocket phones in size, radiated power, battery life, weight and operation. Mobile terminals are designed for vehicular use, fixed terminals are designed for public or private installed use. Both the mobile and handheld terminal types use omnidirectional antennas, fixed terminals use more directive antenna designs for greater efficiency. Ellipso™ terminals will be dual mode terminals, capable of operating either on the Ellipso™ system or on the local terrestrial cellular system. Ellipso™ will also support other more specialized terminal designs. These can include data-only terminals, personal digital assistants, and paging/polling terminals, as well as packages with application and features for specialized markets, such as fisheries or trucking.
