Paging systems are still used in various sectors, including healthcare, public agency, retail, school, and hospitality. A cordless telephone or portable telephone has a portable telephone handset that connects by radio to a base station connected to the public telephone network. The operational range is limited, usually to the same building or within some short distance from the base station. A cellular telephone system is a mobile phone network that is made up of many signal areas, or cells. These cells overlap to create a large coverage area, allowing users to move between cells without losing connection.
