The pagers listen to the signal from the transmitter constantly as long as the pager is turned on. The pager listens for its unique CAP code. When it hears the code, it alerts the user and may provide additional information, depending on the pager type. Regional and national paging networks set up towers, like those used for cell phones , to cover large areas.
On-site paging systems like the ones used by restaurants use a small desktop transmitter. In the next section, we will take a closer look at this device. Sign up for our Newsletter!

Today, some pagers like the Spok T5 and T52 support message encryption using the AES encryption algorithm, which is the industry standard.
With these pagers, each device is programmed with a unique encryption key. Messages are encrypted as they enter the Spok network, sent over the satellite network to the transmitters and then sent over the air to the device, where they are decrypted for display to the user. Whether you need to communicate a system-wide emergency message or let one person know that there is a front desk delivery for them, paging is a fast, efficient, cost-effective and unobtrusive solution.

How does a pager work? What is a paging network? There are two types of paging networks: On-site systems use low and high-power transmitters to send local messages or for in-house notifications, similar to the kind used at a restaurant to let you know that your table is ready.
Wide-area networks rely on high-powered transmitters across the country for nationwide coverage. They are often used in hospitals, hotels, restaurants and other organisations where rapid change and accurate and timely responses to them are required routinely. 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.
