What are pagers? Devices used in attack in Lebanon

Very popular in the 1990s, the pagers — also known as beep — are communication devices, created long before cell phones became popular. On Tuesday (17), the explosion of some of these devices in Lebanon caused the death of at least nine people and injured around 2,800.

According to the Massachusetts Institute of Technology (MIT) the telephone pager was an invention patented in 1949 by Alfred J. Gross an engineer considered a pioneer in wireless mobile communication.

After creating two-way radios for personal use, Al Gross discovered that he could adapt the devices for remote wireless telephone signaling. In other words, he built discriminator circuits into a pocket-sized wireless receiver that responded selectively to specific signals.

The first models launched were only capable of indicating to the recipient the number of the person they wanted to communicate with. From then on, the person would have to use a telephone — which at the time was still a landline —, according to the website. Discover Systems one of the pager manufacturers.

Created to fit in your pocket, over the years, technology evolved and gained larger screens, capable of displaying text messages. This way, the recipient would not have to call the sender and find out the reason for the contact.

Even with the popularization of mobile phones, there are still people who use pagers today. Doctors, restaurants, logistics teams, factory and warehouse workers all take advantage of this method of sending a message immediately without requiring Wi-Fi or a telephone network.
