Wireless Distribution System (WDS)
Overview:
Wireless Distribution System (WDS) is a technology that allows multiple access points (APs) to be interconnected with each other. It is commonly used in wireless networks to extend coverage and provide seamless roaming for clients.

Multiple Access Points:
In a wireless distribution system, multiple access points are interconnected with each other. This means that there are multiple APs that work together to provide wireless coverage in a certain area. These APs are typically connected via Ethernet cables or wireless links.

Interconnection:
The interconnection between the access points allows them to communicate with each other and share information. This enables features like seamless roaming, where clients can move between different APs without experiencing any disruption in their network connection.

Benefits:
1. Extended Coverage: By using multiple access points, the wireless coverage area can be expanded, allowing clients to stay connected even when they move away from the range of a single AP.
2. Load Balancing: With multiple APs, the network can distribute the client load across different access points, preventing any single AP from becoming overloaded.
3. Redundancy: If one access point fails, the other APs in the system can continue to provide network connectivity, ensuring uninterrupted service for clients.

Conclusion:
In a wireless distribution system, multiple access points are interconnected with each other to extend coverage and provide seamless roaming for clients. This technology offers benefits such as extended coverage, load balancing, and redundancy. Therefore, the correct answer is option 'A', which states that multiple access points are inter-connected with each other.
