1.5.1 Definitions concerning deployment
• Coverage area
The coverage area refers to the space within which the user of a mobile must be able to transmit
and receive calls. This area can include coverage both inside and outside a building.
• Base station
The base station is made up of an omnidirectional transceiver. The base station radio coverage
area (called a "radio area") is, in free space, spherical and centered on the base station. A base
station must belong to a trunk group (in the MMCs).
• Overlapping base stations
Base stations with the same radio coverage (3 base stations maximum). Each base station
manages a certain number of mobiles, depending on their distribution.
• Examples:
case 1: B1, B2, and B3 are remote base stations located 30 to 50 cm from each other.
They constitute a single radio area. At any location within the radio area, a cordless
handset sees the three base stations with the same radio level. This configuration
corresponds to three base stations located in the same area.
