Describe the two groups that LEO satellites can be divided into.
What will be an ideal response?
LEO satellites can be divided into Little LEO and Big LEO groups. Little LEOs provide pager, satellite telephone, and location services. Using a Little LEO satellite, a user can make a phone call from anywhere on Earth. In contrast, cellular telephone services require the user to be within RF range of a transmission tower. Big LEOs carry voice and data broadband services, such as wireless Internet access. Some satellite Internet services provide shared downstream data rates of up to 400 Kbps but require a telephone connection for upstream data to an ISP. Another LEO wireless Internet service provides two-way data services with speeds of up to 500 Kbps. Two-way satellite Internet users need a two-foot by three-foot dish antenna and two modems (one each for uplink and downlink).
