FDMA (Frequency Division Multiple Access) - (BCA / B.Tech)

FDMA (Frequency Division Multiple Access) in Computer Networks:

FDMA (Frequency Division Multiple Access) is a multiplexing technique used primarily in telecommunication systems. Its purpose is to divide a single channel among various users so that all users can use their communication service without interference. FDMA is mainly used in mobile networks, satellite communications, and other wireless systems.

Structure and Working of FDMA:

In FDMA, the available bandwidth is divided into different frequency channels, and each user is allocated a specific frequency. This means all users have different frequencies for communication. This process ensures maximum utilization of the communication channel.

Advantages of FDMA:

Simplicity and Reliability: The structure is simple, and communication is reliable due to dedicated frequencies.
Real-Time Communication: Allows for real-time data transmission as all users can communicate simultaneously on their frequencies.
Low Temporal Variation: Leads to better communication quality as each user has a fixed frequency.

Disadvantages of FDMA:

Bandwidth Wastage: If a user is not using their allocated frequency, that bandwidth is wasted.
Lack of Flexibility: Frequency allocation is static, making it difficult to allocate more bandwidth to a user if needed.
Increased Complexity: Managing the system can become complex when implemented for many users.

Uses of FDMA:

It is used in satellite communication, mobile networks, and television broadcasting.
