The pager is commonly believed to have gone the way of dial-up internet, the floppy disk, and other outmoded technologies. However, it is no digital dodo. While most people conduct much of their regular communications on smartphones, paging systems remain in use within certain fields and settings. Hospitals continue to rely on these timely tools thanks to their strong network. Business owners assign pagers to employees to quickly touch base in large work environments. Even churches benefit because nursery workers can surreptitiously page parents without interrupting the service.
With that said, there is a kernel of truth to the common misconception about paging systems. The mass-produced beepers of the 1980s and 1990s are mostly gone. In the intervening decades, engineers have developed more sophisticated devices with state-of-the-art technology. If you run a business, volunteer at a church, or work in a variety of fields, you may find a guide to modern paging systems quite insightful.
