7-4 Wireless Bridging Explained

Wireless bridging is a technique used to connect two or more networks using wireless technology. This method allows devices in different networks to communicate with each other as if they were on the same local network. Understanding wireless bridging is essential for the MikroTik Certified Network Associate (MTCNA) certification.

Key Concepts

1. Wireless Bridging Overview

Wireless bridging involves using wireless devices to create a bridge between two or more networks. This bridge allows data to be transmitted wirelessly between the networks, enabling devices in different locations to communicate seamlessly.

2. Types of Wireless Bridging

There are two main types of wireless bridging:

• Point-to-Point Bridging: Connects two separate networks using a direct wireless link between two devices.
• Point-to-Multipoint Bridging: Connects one central network to multiple remote networks using wireless links.

3. Wireless Bridging vs. Wireless Repeater

While both wireless bridging and wireless repeaters extend network coverage, they serve different purposes:

• Wireless Bridging: Connects separate networks, allowing devices in different networks to communicate.
• Wireless Repeater: Extends the range of a single network by repeating signals, but does not connect separate networks.

4. Configuration Steps

Configuring wireless bridging on a MikroTik router involves several steps, including setting up the wireless interface, defining the bridge, and configuring the security settings.

Detailed Explanation

Wireless Bridging Overview

Wireless bridging creates a wireless link between two or more networks, allowing devices in these networks to communicate as if they were on the same local network. This is particularly useful for connecting networks in different physical locations, such as buildings or campuses.

Types of Wireless Bridging

Point-to-Point bridging is ideal for connecting two networks that are within range of each other. Point-to-Multipoint bridging is useful for connecting a central network to multiple remote networks, such as in a campus or large office environment.

Wireless Bridging vs. Wireless Repeater

Wireless bridging is used to connect separate networks, while wireless repeaters are used to extend the range of a single network. Bridging allows for more complex network topologies and can be more secure, as it does not expose the entire network to the extended area.

Configuration Steps

To configure wireless bridging on a MikroTik router, follow these steps:

1. Navigate to the Wireless menu and create a new wireless interface.
2. Set the mode to bridge and define the SSID and channel.
3. Create a bridge interface and add the wireless interface to it.
4. Configure the security settings, such as WPA2, to secure the wireless link.
5. Apply the configuration and test the connection between the networks.

Examples and Analogies

Example: Wireless Bridging Overview

Think of wireless bridging as a wireless bridge connecting two islands. Just as the bridge allows people to travel between the islands, wireless bridging allows devices in different networks to communicate.

Example: Types of Wireless Bridging

Consider Point-to-Point bridging as a single bridge connecting two islands. Point-to-Multipoint bridging is like a central island with multiple bridges connecting it to several smaller islands.

Example: Wireless Bridging vs. Wireless Repeater

Imagine wireless bridging as building a new bridge between two towns, allowing residents to travel directly between them. Wireless repeaters are like adding more roads within a town to extend its reach, but they do not connect separate towns.

Example: Configuration Steps

Configuring wireless bridging is like building a bridge. First, you need to lay the foundation (create the wireless interface). Then, you construct the bridge (define the bridge interface). Finally, you secure the bridge (configure security settings) to ensure safe travel between the networks.

By mastering wireless bridging, you can effectively connect separate networks using wireless technology, enabling seamless communication and expanding network coverage.
