When Was the Pager Invented
Long before email and long before texting, there were pagers, portable mini radio frequency devices that allowed for instant human interaction. Invented in 1921, pagersââ¬âor beepers as they are also knownââ¬âreached their heyday in the 1980s and 1990s. To have one hanging from a belt loop, shirt pocket, or purse strap was to convey a certain kind of statusââ¬âthat of a person important enough to be reached at a moments notice. Like todays emoji-savvy texters, pager users eventually developed their own form of shorthand communications. The First Pagers The first pager-like system was put into use by the Detroit Police Department in 1921. However, it was not until 1949 that the very first telephone pager was patented. The inventors name was Al Gross, and his pagers were first used in New York Citys Jewish Hospital. Al Gross pager was not a consumer device available to everyone. In fact, the FCC did not approve the pager for public use until 1958. The technology was for many years reserved strictly for critical communications between emergency responders like police officers, firefighters, and medical professionals. Motorola Corners the Market In 1959, Motorola produced a personal radio communications product that they called a pager. The device, about half the size of a deck of cards, contained a small receiver that delivered a radio message individually to those carrying the device. The first successful consumer pager was Motorolas Pageboy I, first introduced in 1964. It had no display and could not store messages, but it was portable and it notified the wearer by the tone what action they should take. There were 3.2 million pager users worldwide at the beginning of the 1980s. At that time pagers had a limited range and were used mostly in on-site situationsââ¬âfor example, when medical workers needed to communicate with each other within a hospital. At this point, Motorola was also producing devices with alphanumeric displays, which allowed users to receive andà send a message through a digital network. A decade later, wide-area paging had been invented and over 22 million of the devices were in use. By 1994, there were over 61 millionà in use, and pagers became popular for personal communications as well. Now, pager users could send any number of messages, from I Love You to Goodnight, all using a set of numbers and asterisks. How Pagers Work The paging system is not only simple, but its also reliable. One person sends a message using a touch-toneà telephoneà or even an email, which in turn is forwarded to the pager of the person they want to talk to. That person is notified that a message is incoming, either by an audible beep or by vibration. The incoming phone number or text message is then displayed on the pagers LCD screen. Heading for Extinction? While Motorola stopped producing pagers in 2001, they are still being manufactured. Spok is one company that provides a variety of paging services, including one-way, two-way, and encrypted. Thats because even todays smartphone technologies cant compete with the reliability of the paging network. A cell phone is only as good as the cellular or Wi-Fi network off of which it operates, so even the best networks still have dead zones and poor in-building coverage. Pagers also instantly deliver messages to multiple people at the exact same timeââ¬âno lags in delivery, which is critical when minutes, even seconds, count in an emergency. Finally, cellular networks quickly become overloaded during disasters. This doesnt happen with paging networks. So until cellular networks become just as reliable, the little beeper that hangs from a belt remains the best form of communication for those working in the critical communications fields.
