Performance Analysis of a Hierachical Cellular Mobile Communication System

Calls, primarily cal manner. Microcells are primarily used to serve handsets in slow motion. Handoff calls in microcells can overflow in- to regular cells or macrocells. Likewise, regular cells are used mainly to su ort handsets in moving vehicles. Handoff calls long distance or international, can also be launched directly to the satellite. Performance ineastires such as call blocking rate, call drop rate, and channel utilization are succcessfiilly derived. Numerical exaniples are also provided to demonstrate several interesting phenomena.
