What Is a Pager and How Does it Work?

What is a Pager? The Rise, Decline, and Surprising Staying Power of an Icon

Introduction

In today‘s world of smartphones, smartwatches, and omnipresent internet connectivity, you may be surprised to learn that pagers—those clunky, beeping devices from the 80s and 90s—are still around and serving an important role in many industries. Despite largely disappearing from the consumer world, over 10 million pagers are still in use in the United States alone as of 2024.

So what exactly is a pager, how do they work, and why are they still relevant in an age of far more advanced technology? In this deep dive, we‘ll explore the past, present, and potential future of pagers. We‘ll look at how they rose to popularity, the key advantages that have allowed them to persist to the present day, and new technologies like Driver Support One that are giving pagers additional capabilities and relevance.

Whether you‘ve never actually seen a pager in person or you‘re part of the shrinking but dedicated group that still relies on them every day, read on for an illuminating look at one of the most iconic communication devices of the 20th century.

What is a pager?

First, let‘s nail down a definition. A pager (also known as a beeper) is a small telecommunications device that receives messages via radio signals. The most basic pagers can only receive numeric messages, while more advanced models can display text messages and even allow users to send simple responses.

Pagers typically have a small screen to display messages, a notification system (a beeping sound, flashing light, or vibration), and simple buttons or a QWERTY keyboard for user interaction. They connect to a local or regional paging network via radio towers.

Compared to cell phones, the functionality of pagers is very basic. But this simplicity is part of their enduring appeal in an age of information overload and constant connectivity. We‘ll explore more of the advantages of pagers later on.

The rise and fall of pagers

Pagers have a history dating back to the 1920s, when the Detroit Police Department first used a pager-like radio communications system to dispatch police cars. However, it wasn‘t until the 1950s that the first telephone pager was patented, and the 1960s when pagers started to be used more widely by emergency services.

Motorola coined the term "pager" in 1959 and went on to introduce a range of pager models through the 60s and 70s. By the 1980s, pagers had entered the mainstream and were seen as an icon of the nascent mobile communications age. Pager use peaked in the mid-1990s, with over 61 million pager users in 1994.

However, the meteoric rise of cell phones in the late 90s spelled the beginning of the end for pagers as a mainstream device. By 2001, major pager manufacturers like Motorola were already phasing out pager production.

The introduction of SMS text messaging, along with cell phones‘ additional capabilities and continually expanding networks, made pagers increasingly obsolete for most people. By the early 2000s, pagers had all but disappeared from the consumer world.

How pagers work

All pagers rely on a similar system to receive messages. Each individual pager has a unique CAP (Channel Access Protocol) code that identifies it on a paging network.

To send a message, you transmit the receiving pager‘s CAP code along with the message to a terminal. This then gets relayed to a network of radio towers, which broadcast the message across a specific frequency.

Pagers tuned into that frequency listen for their CAP code. When a pager receives a message with its CAP code, it notifies the user via a beep, vibration, or flashing light and displays the message on the screen.

Paging networks can either be localized on-site systems confined to a specific building like a hospital, or wider-reaching systems relying on radio towers owned by carriers.

Different pager types and form factors exist for different use cases:

• Numeric pagers can only receive numbers (no alphabetic characters).
• Alphanumeric pagers can receive numbers and text, and have a small screen to display messages.
• Two-way pagers have QWERTY keyboards that allow users to send replies via a return paging network or over an internet gateway.
• Voice pagers can receive voice messages that users can replay as audio.

While numeric and alphanumeric pagers are the most common, these other types still see use for specific applications.

Who still uses pagers today?

While you‘d be hard-pressed to find anyone still carrying a pager for personal use, pagers remain surprisingly prevalent in a number of industries where their simplicity and reliability offer key advantages:

Healthcare – Hospitals and other healthcare facilities are one of the biggest remaining users of pagers. According to research firm Frost & Sullivan, 80% of hospitals still rely on pagers for communication as of 2022.

The simplicity, reliability, and unobtrusive nature of pagers makes them well-suited to healthcare environments. Many hospitals use on-site paging systems to minimize cellular and WiFi dead zones.

Public safety and emergency services – Pagers are also commonly used by emergency services like firefighters, EMTs, and crisis response teams to relay urgent alerts.

The reliable coverage and signal penetration of paging networks makes them preferable to cell phones in many emergency situations. Volunteer firefighters and EMTs often carry pagers to receive dispatch notifications.

IT and customer support – Some IT support and customer service teams equip technicians with pagers to receive alerts about system outages, technical issues, or customer callbacks without the distraction of a cell phone.

Hospitality – Pagers can be an unobtrusive way for hotel staff, wait staff, housekeeping, or hosts to receive notifications and requests. Some restaurants use pagers to alert customers when their table is ready.

Industrial and manufacturing – In industrial facilities where cell phones may not be permitted due to safety regulations, pagers can provide a way for workers to receive urgent alerts or equipment notifications.

So while pagers have disappeared from mainstream society, they remain an important tool in industries where simplicity and reliability are paramount.

Advantages of pagers in an age of smartphones

At first glance, it may seem puzzling that anyone would still carry a pager in an age of smartphones. However, pagers still offer some unique advantages:

Reliability – Pager systems use stronger radio signals and simpler protocols than cellular networks, making them less prone to dead zones or service interruptions. Pager transmissions can reach further with fewer towers.

Battery life – With much smaller screens and no cellular, data, or WiFi radios, pagers have batteries that can last for weeks or even months on a single charge.

Simplicity – The basic, single-purpose nature of pagers can be an advantage in environments where focus and quick response to messages are essential. There are no distracting apps or notifications.

Low cost – Pagers and pager services are significantly cheaper than smartphones and most cellular plans, making them a cost-effective option for businesses managing large fleets of users who only need limited messaging capabilities.

Coverage – In some regions, paging networks still offer wider and more reliable coverage than cellular networks, particularly for indoor and underground environments.

Pagers also offer a simple and compliant communication method for sensitive industries like healthcare, where privacy regulations restrict the use of devices that store unencrypted customer data.

Disadvantages compared to modern devices

Of course, pagers also come with significant limitations compared to modern connected devices:

Limited messaging – Most pagers are receive-only and can handle only short messages. Composing messages on a pager is slow and cumbersome compared to a smartphone keyboard.

Lack of features – Pagers can‘t make voice calls, browse the web, run apps, or do any of the myriad other things that smartphones can do. They‘re inherently limited in functionality.

Reliance on paging networks – Pagers are tied to a specific paging carrier, and can‘t move between networks like unlocked cell phones can. Coverage may be limited outside of specific geographic areas.

Fewer developers – As pager usage dwindles, there are fewer developers still creating software, applications, and new features for pager systems compared to the massive smartphone ecosystem.

Interfacing with newer systems – Pagers aren‘t natively compatible with modern messaging and alerting systems. They often require extra steps or software to receive notifications from contemporary systems.

Ultimately, while pagers still excel in simplicity and reliability, they lack the flexibility and robust ecosystem of modern mobile devices. It‘s likely pagers will continue to fall out of use except in niche applications as smartphones become even more ubiquitous.

The role of Driver Support One

To keep pagers relevant and integrate them with modern systems, some vendors have developed solutions to bridge the gap. One such system is Driver Support One, a software platform that interfaces with paging terminals.

Driver Support One essentially acts as middleware between paging systems and enterprise software. It allows messages and alerts from operational systems, electronic health records, workforce management platforms, and other software to be composed and sent to pager users.

Messages can be sent to individual pagers or broadcast to groups based on rules and protocols configured in the software. Driver Support One supports sending messages to a variety of different pager types from a range of manufacturers.

For hospital paging, Driver Support One integrates with nurse call systems, patient monitoring equipment, health information systems and other platforms to route alerts to the appropriate staff members‘ pagers based on configurable rules and schedules.

Similar middleware platforms exist for industrial and IT alerting use cases to monitor equipment and systems and automatically page technicians and engineers when issues are detected.

By interfacing with these types of middleware platforms, paging systems can gain additional capabilities and remain a viable communication method for critical industries even as general usage declines.

The future of pagers

While pagers are unlikely to ever return to the mainstream, it‘s clear that they still have an important role to play in critical communication for industries like healthcare and public safety, where reliability and simplicity are essential.

As long as paging networks remain operational, pagers will likely persist in these applications thanks to their core advantages of signal coverage, battery life, and simplicity.

However, the long-term future of pagers will depend on the viability of the paging networks themselves. As carriers consolidate and look to repurpose spectrum for more lucrative wireless broadband services, the availability and footprint of paging networks may start to diminish in the coming years.

Most industry analysts expect pager usage to continue to slowly but steadily decline in the coming decade. It‘s likely that paging systems will eventually be subsumed by the advance of 5G and 6G cellular networks that match their coverage and reliability.

But don‘t write off the humble pager just yet. With their streamlined utility and niche but loyal user base, pagers may still be beeping and buzzing away in specific applications for years to come, just like other "outdated" but useful technologies like fax machines. And as long as there is demand, platforms like Driver Support One will work to keep pagers integrated with the cutting edge.

Conclusion

Pagers may seem like a quaint anachronism in an age where we all carry powerful internet-connected computers in our pockets at all times. But beneath their old-school exterior, pagers still offer some unique and valuable capabilities.

For hospital workers, first responders, IT engineers, and others who need simple, ultra-reliable, immediate communication without distraction, pagers remain a go-to tool. And with platforms like Driver Support One enabling integration with modern systems, pagers may still have an important part to play even as more advanced technologies develop.

So the next time you hear a pager beep in a hospital or see a firefighter unclip one from their belt, remember that you‘re looking at a piece of technology that, against all odds, is still doing its job quite well after all these decades. Not bad for a modest little device with a monochrome screen.
