Full Answer

Pagers listen to one radio frequency all the time and have a specific address, called a Channel Access Protocol code, that lets it know which message is addressed to an individual pager. When the pager receives a message that has its unique code, it alerts the user and may provide more information, depending on what type of pager is in use. As of 2014, hospitals and restaurants use pagers to instantly communicate important information to those who need it.

    How do wireless chargers work?

    A:

    Wireless chargers use an electromagnetic field to charge devices without a direct connection. An induction coil in the charger creates the alternating electromagnetic field, and when this field acts on a similar coil inside the electronic device, it creates current and charges the battery. Most chargers have an extremely short range and require the electronic device to be placed directly on the charging pad to function.
