A Public Land Mobile Network (PLMN) is a terrestrially operated radio network
that provides a public mobile radio service and can be used equally by vehicles or pedestrians. PLMN networks are often connected to and extend fixed networks
such as the public switchedtelephone
network(PSTN) or other terrestrial mobile networks such as the GSM network or the UMTS network. Other networks include Broadband Wireless Access (BWA), Wireless Local Loop (WLL), Wireless Metropolitan Area Network (WMAN) and WiMAX. It is the area where services are provided by network operators
. PLMNs can provide users with diverse services comparable to the services offered by fixed networks. This is particularly interesting for topographically difficult areas where base station maintenance is difficult or where RF emissions impair reception. Since PLMN networks incorporate digital and analogue technology, nationwide communications coverage is ensured.
