The coverage overlap, combined with use of satellite communications, can make paging systems more reliable than terrestrial based cellular networks in some cases, including during natural and human-made disaster. [4] This resilience has led public safety agencies to adopt pagers over cellular and other commercial services for critical messaging.
Consumer Cellular uses towers from two other cellular networks: T-Mobile, and AT&T. It’s an MVNO, which means it borrows the technology of other cellular providers to provide expansive coverage.
(Reuters) -As mobile phones became the world's main communications tool, pagers, also known as beepers because of the sound they make to notify users about incoming messages, were largely rendered ...

An emergency communication system may be composed of a product and its associated hardware and software, as owned by the entity using it (e.g., an on-site paging network), or as a service owned and provided by a third-party (e.g., a cellular carrier's SMS network). Each have their own advantages and disadvantages; however, despite perception ...
Described in more commercial terms, PCS is a generation of wireless cellular-phone technology, that combines a range of features and services surpassing those available in analogue- and first-generation digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
Without knowing exactly how the attackers modified the pagers, it is hard to know for sure that our consumer devices are safe. But experts advise that there is no need to worry.
Different cellular companies in the same region may use different levels of cellular technology and different parts of the radio spectrum. In addition to radio frequencies used to connect handsets with cellular base stations, other parts of the radio spectrum are used to interconnect base stations and the wired telephone network.
