Which technique is used to allow multiple users to share the same bandwidth in wireless communication?

• A. Coding
• B. Modulation
• C. Multiplexing
• D. Filtering

Answer: (C)

Multiplexing is the technique employed to enable multiple users to share the same bandwidth in wireless communication. This is achieved by dividing the communication channel into several separate channels, allowing simultaneous data transmission. Different forms of multiplexing, such as Time Division Multiplexing (TDM) or Frequency Division Multiplexing (FDM), manage how and when each user accesses the shared bandwidth. For instance, in TDM, time slots are allocated to each user in a rotating manner, while FDM assigns different frequency bands. This efficient use of the available bandwidth enhances the capacity of the communication system, allowing multiple connections without interference, which is a cornerstone of modern wireless communication protocols.
