What is a Pager? - A Deep Dive into the Technology and its Evolution
Pager Functionality
A pager is a one-way communication tool that picks up signals from a base station. When someone sends a message to a pager, it lights up or makes a noise to alert the user.
Paging Network
Pagers use a paging network made up of transmitters and base stations. They communicate using protocols like POCSAG and FLEX, which help send messages to the devices.
Contrast with Two-Way Communication
Unlike cell phones that allow two-way conversations, pagers only send messages. This feature makes them useful in situations where quick alerts are needed.
Types of Pagers
There are several types of pagers:
- Numeric Pagers: Only show numbers.
- Alphanumeric Pagers: Can display short messages.
- Voice Pagers: Can speak messages.
Reasons for Persistence
Pagers remain in use for several reasons:
- They are very reliable, especially in bad cell service areas.
- They use less battery than smartphones.
- They can work even where cell service fails.
Pager Protocols
Protocols like POCSAG and FLEX help organize how messages get sent to pagers, ensuring they are received correctly.
Security of Pagers
Pager communication usually lacks strong encryption, making it slightly less secure than other methods. Still, they are less prone to hacking due to their technology.
Inside a Pager
A pager includes several basic parts:
- Receiver: Picks up the signal.
- Decoder: Understands the message.
- Display: Shows the message or number.
- Alert Mechanism: Notifies the user with sound or vibration.
