While the fundamental concept of pagers remains the same, modern healthcare has given them a digital makeover. Today, pagers can receive not just text messages but also critical patient data, alarms, and even integration with Electronic Health Records (EHR) systems.

Modern paging networks use sophisticated satellite connections between the core messaging network and transmitter towers. This bypasses vulnerable telephone and RF link networks, providing a higher degree of efficacy and security.

A pager or a beeper is a wireless telecommunication device that receives and shows alphanumeric texts or voice messages. It beeps when it receives a signal, and depending on the pager device, you can send back a signal. Even though pagers are no longer famous today, it is still relevant to specific industries like public safety and healthcare.
