The WDS (Wireless Distribution System) is a system that allows the expansion of a wireless network by interconnecting access points of a WLAN (Wireless Local Area Network) network.

This system allows access points to communicate with each other without using a wired network infrastructure as a backup, making it easy to create an extended wireless network that can cover larger areas than a single access point.

The main characteristics and uses of WDS are:

1. Network extension: WDS is used to expand the range of a wireless network, allowing access points to communicate with each other and repeat the signal, thereby extending network coverage to areas that would otherwise be out of reach of a single access point. .
2. Wireless connection: By using WDS, you eliminate the need for cables to connect access points. This is particularly useful in environments where cable installation is difficult, expensive or impractical.
3. Operating modes: Devices that support WDS can generally operate in several modes, such as bridge, in which two wired networks are connected wirelessly; repeater (repeater), where the range of the wireless signal is extended; and wireless client, where the access point acts as a client of another access point.
4. Compatibility: Not all wireless access points support WDS, and the implementation of WDS may vary between different manufacturers. This can cause interoperability issues when trying to connect access points from different brands.
5. Safety: Security is an important consideration when using WDS, as the extended network must be protected from unauthorized access. It is important to ensure that all access points in the WDS system use the same encryption methods and security keys.
6. Configuration: Setting up a network using WDS can be more complex than setting up a traditional wireless network. It is important to carefully follow the manufacturer's instructions and, in some cases, it may be necessary to adjust the settings to ensure optimal communication between access points.

WDS offers a flexible and effective solution for extending the coverage of a wireless network, but requires careful planning and proper configuration to ensure optimal performance and robust security.
