3 Wireless Bridging Explained

1. Understanding Wireless Bridging

Wireless bridging is a method of connecting two or more networks using wireless signals instead of physical cables. This technique allows devices in different physical locations to communicate as if they were on the same local network. Wireless bridging is particularly useful in scenarios where running physical cables is impractical or cost-prohibitive.

2. Key Concepts

There are three primary concepts to understand when configuring Wireless Bridging in MikroTik:

a. Bridge Mode

Bridge mode is a networking mode where devices are connected to form a single logical network. In wireless bridging, this means that multiple wireless access points (APs) or routers are configured to act as a bridge, allowing devices connected to different APs to communicate as if they were on the same local network.

For example, if you have two offices in different buildings, you can use wireless bridging to connect them, allowing devices in both offices to share resources and communicate seamlessly.

Think of bridge mode as a virtual Ethernet cable connecting two networks. Just as a physical cable allows devices to communicate, bridge mode allows wireless devices to do the same.

b. WDS (Wireless Distribution System)

WDS is a technology that allows multiple wireless access points to communicate with each other and extend the range of a wireless network. In MikroTik, WDS can be used to create a wireless bridge between two or more APs, enabling them to relay data between each other.

For instance, if you have a large warehouse and want to extend the wireless coverage to a distant section, you can use WDS to connect multiple APs, ensuring that all areas of the warehouse have reliable wireless coverage.

Imagine WDS as a relay race where each AP passes the data to the next one, extending the reach of the wireless network.

c. Repeater Mode

Repeater mode is a configuration where a wireless device receives a signal and retransmits it to extend the range of the network. In MikroTik, this mode can be used to bridge two networks by repeating the wireless signal between them.

For example, if you have a guest house far from your main house and want to provide wireless internet access, you can use a MikroTik device in repeater mode to extend the wireless signal from the main house to the guest house.

Think of repeater mode as a loudspeaker that amplifies the sound from a microphone, extending the reach of the message.

3. Practical Examples

Example 1: Connecting Two Offices

Two offices located in different buildings need to be connected to share resources and communicate seamlessly. By configuring MikroTik devices in bridge mode with WDS, the offices can be connected wirelessly, allowing devices in both locations to access shared files and applications as if they were on the same network.

Example 2: Extending Wireless Coverage

A large warehouse needs reliable wireless coverage in all sections. By using MikroTik devices in repeater mode, the wireless signal can be extended to distant areas, ensuring that all devices in the warehouse have access to the network.

4. Insightful Value

Understanding wireless bridging and its key concepts is essential for creating flexible and efficient network solutions. By leveraging bridge mode, WDS, and repeater mode, you can extend network coverage, connect remote locations, and enhance communication without the need for physical cabling. This knowledge is invaluable for network administrators aiming to optimize network performance and connectivity in various environments.
