How does beepers work

In simple terms, a wireless paging system transmits messages to one or more pagers, but a message can only be received by the pager that the message is intended for. Each pager has a specific address and each message is addressed to one or more specific pagers. Think of a pager as the thing that receives and displays a message. There are several devices that can do this. For example, the main ones are:. Dedicated wireless personal pagers Smartphones with a special app software application or program WiFi digital phones Tablets Blackberrys.

A personal pager must be small, robust, reliable and secure. Each uses wireless technology. The message is carried by Radio Frequency RF energy transmitted by the paging controller. However, other devices such as Smartphones can not only receive a message, they can also transmit an acknowledgement indicating 'message received' back to the paging controller. The antenna captures some of the RF radiation transmitted by the paging transmitter and feeds it to the receiver.

Yet even today, no mobile communication technology is more reliable, survivable, and affordable than the pager. In fact, pagers are filling a crucial role in the response to COVID—you can learn why pagers are still so crucial in healthcare today in this previous blog post. A pager is a small telecommunication device that receives radio signals from the paging network.

In the case of two-way pagers, radio signals may be sent from the device as well. Transmitters in the paging networks broadcast signals over a specific frequency.

Pagers that are physically in range of the transmitters listen to the signal from the transmitter. Learn more about how pagers work in this infographic. Paging networks are superior to cellular networks in a lot of ways.

Notably, paging transmitters use high frequency radio signals with antennas that are typically located high off the ground so they can extend farther with fewer transmitters and less interference. Paging networks also use multiple towers simultaneously , providing overlapping read: more reliable coverage. 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. Not all paging systems are created alike. The most secure and reliable paging networks rely on a checkerboard pattern of transmitter sites. How do you say I love you on a pager? Do pagers still work? Can you activate an old pager?
