CDPD channel is _________a)Simplexb)Complexc)Duplexd)ExpensiveCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Each CDPD channel is duplex in nature. The forward channel serves as a beacon and transmits data from the PSTN side of the network, while the reverse channel links all mobile users to the CDPD network and serves as the access channel for each subscriber.

Answer

Explanation: CDPD is a data service for first and second generation US cellular systems and uses a full 30 kHz AMPSchannel on a shared basis.

Answer

Cellular digital packet data (CDPD) is a secondary packet-switched data service which uses radio channels from advanced mobile phone standard (AMPS) cellular networks. The CDPD service is completely invisible to the AMPS service which maintains priority.

Answer

Understanding CDPD Channels
CDPD stands for Cellular Digital Packet Data, a technology primarily used for mobile data transmission. The nature of a CDPD channel is significant in understanding its functionality.
What is a Duplex Channel?
A duplex channel allows for two-way communication. In the context of CDPD, this means that data can be sent and received simultaneously between devices. This capability is essential for efficient and faster communication in mobile networks.
Features of Duplex Channels:

Simultaneous Transmission: Both parties can send and receive data at the same time, enhancing communication efficiency.
Improved User Experience: Users can interact with applications and services without delays, making it ideal for real-time data transmission.
Increased Throughput: The ability to handle multiple data streams concurrently maximizes the use of available bandwidth.

Why CDPD is Considered Duplex?
CDPD is designed to support mobile computing with continuous connectivity. The duplex nature of the channel is crucial for:

Real-Time Applications: Applications like video calls, online gaming, and live streaming require two-way communication.
Data Efficiency: Efficiently utilizing network resources by allowing simultaneous data flow enhances overall network performance.

Conclusion
In summary, the CDPD channel is classified as duplex due to its capability to facilitate two-way communication, which is vital for modern mobile applications and services. Understanding this aspect helps in grasping the importance of CDPD in the realm of mobile networking.
