Satellite Personal Communication Services (S-PCS)
نویسنده
چکیده
Satellite personal communication services (S-PCS) are one of the recent systems available to global mobile user. The benefits with using satellites are greater coverage, especially in remote areas such as the poles or in the middle of the oceans. However, satellite communication is expensive and for personal use still in its infancy. Today there exist a number of operators delivering more or less global S-PCS.
