Accommodate a large number of users
Large geographic area
Limited frequency spectrum
Large frequency spectrum
Answer is Wrong!
Answer is Right!
The correct answer is D. Large frequency spectrum.
A cellular telephone system is a radio system that uses cells to provide mobile telephone service. A cell is a geographical area that is served by a base station. Base stations are connected to the public switched telephone network (PSTN) by wired or wireless links.
The main characteristics of a cellular telephone system are:
- Accommodates a large number of users: Cellular telephone systems can accommodate a large number of users by dividing the service area into cells. Each cell is served by a base station, which is connected to the PSTN. The base station communicates with mobile phones within its cell using radio waves.
- Large geographic area: Cellular telephone systems can cover a large geographic area by using a network of base stations. The base stations are connected to each other by wired or wireless links.
- Limited frequency spectrum: Cellular telephone systems use a limited frequency spectrum. This is because the radio spectrum is a finite resource. To accommodate a large number of users, cellular telephone systems use frequency reuse. Frequency reuse allows the same frequency to be used in different cells, as long as the cells are not adjacent.
The option that is not a characteristic of cellular telephone system is D. Large frequency spectrum. This is because cellular telephone systems use a limited frequency spectrum.
