What is the difference between a pocket pager and a cordless phone?

Answer 1

• pager, you cannot make or receive calls, when someone calls you the pager beeps and you can read the caller's number on the pager's display, you then must find a phone and call the caller back. The radio signal that sends the number to your pager and makes it beep is usually transmitted from a single tower for the whole city using medium to high power very narrow band radio.
• cordless phone, an ordinary landline phone with separate base and handset connected by short range radio instead of a cord.
• cellphone, a fully mobile phone using medium range spread spectrum radio to connect to a network of "cell towers" instead of needing any wires.
