Question

WLL is used in the areas where telephone connection cannot be provided. (true or false)​

Answer 1

Answer:

PSTN stands for Public Switched Telephone Network, or the traditional circuit-switched telephone network. This is the system that has been in general use since the late 1800s.

Using underground copper wires, this legacy platform has provided businesses and households alike with a reliable means to communicate with anyone around the world for generations.

The phones themselves are known by several names, such as PSTN, landlines, Plain Old Telephone Service (POTS), or fixed-line telephones.

PSTN phones are widely used and generally still accepted as a standard form of communication. However, they have seen a steady decline over the last decade.
