Answer 2

Answer:

Option C - Only ii and iii is the correct answer.

Explanation:

• Time Division Multiple Access (TDMA) is a cellular phone communication system that uses digital signals.
• It allows multiple users to share the same frequency without interfering with one other.
• Its technology separates a signal into multiple time slots, allowing for more data to be carried.period
• Because it necessitates precise synchronisation between the transmitter and the receiver, Time Division Multiple Access (TDMA) is a complicated technology.
• In digital mobile radio systems, TDMA is employed.
• Individual mobile stations assign a frequency for the exclusive use of a time interval on a cyclical basis.
• In most circumstances, a station is not granted the entire system bandwidth for a given period of time.
• However, the system's frequency is divided into sub-bands, with each sub-band using TDMA for multiple access.
• Carrier frequencies refer to sub-bands.
• Multi-carrier systems refer to mobile systems that employ this method.

Hence, regarding TDMA, the transmission time are always separated in time and the more users cannot use the single frequency, these statements are true.
