Base stations enable radio communication between the radio exchange and cordless phones. A base station communicates with the radio exchange via two 2B+D interfaces, requiring a two twisted pair cable. The two 2B channels provide eight 32kbit/s speech path between a base station and the radio exchange, enabling a base station to handle eight simultaneous calls. Except for data communication these two twisted pairs can also be used to distribute power to the base stations.
Base stations can be powered either via a local power supply or via the modular cabinet. With the first method, an AC-adapter or another power source that is not routed via the cabinet powers base stations. The maximum cable length between base station and radio exchange is only data limited and may reach up to 3500 metres. With the second method, power is distributed via the cabinet and base station cabling. The cable length between base station and cabinet now depends on the number of twisted pairs used for power, the type of cable and environmental noise.
The number of base stations used in a system depends on the area to be covered and the traffic density. Typical in-house coverage is a 20-metre radius. In practice the cell size may vary between 10 metres indoors in worst case situations, up to 300 metres outdoors in free space.
The Ericsson BS3xx range of base stations offers a variety of coverage patterns to suit different situations. By choosing the right mix of base stations and the appropriate antennae quality coverage and sufficient traffic capacity exactly where needed can be ensured.
