What is a wireless WiFi bridge?

What is a WiFi bridge? A WiFi bridge replaces ethernet cabling. It is set up in a fixed configuration to have one purpose. In a point-to-point configuration, typically in outdoor environments the bridge will be designed to span a distance to carry data from a point to another as if you had a cable joining the two.

A wireless WiFi bridge is a device or system that connects two separate networks (or network segments) wirelessly, using WiFi signals, to effectively extend a network's reach or connect devices that are not easily wired. Think of it as creating a wireless "bridge" between two networks, allowing them to communicate as if they were directly connected.
Here's a more detailed explanation:

How it works:
Two Access Points:
A wireless bridge typically involves two wireless access points (or routers configured in bridge mode).
Point-to-Point Connection:
These access points are configured to communicate directly with each other, forming a point-to-point wireless link.
Network Extension:
One access point connects to the main network, and the other connects to the remote network or device. The bridge then relays data between the two networks.
No Cables Needed:
This eliminates the need for physical cables to connect the two networks, especially useful when they are located far apart or in areas where cabling is difficult.

Key Features:
Extends WiFi Range:
A wireless bridge can significantly extend the range of a WiFi network, allowing you to access the internet in areas where the main router's signal doesn't reach.
Connect Remote Devices:
It can connect devices or networks in separate buildings, offices, or locations, allowing them to share resources and access the same internet connection.
Security:
Wireless bridges often use encryption to secure the connection between the two access points, protecting data transmitted over the wireless link.
Point-to-Point or Point-to-Multipoint:
Some bridges can connect multiple remote networks to a central one (point-to-multipoint), while others are designed for a single connection (point-to-point).
Applications:
Wireless bridges are used in various scenarios, including connecting buildings on a campus, providing internet access to a guest house, or linking security cameras in a remote location.
