Which method connects two or more wireless networks together?

Wireless bridging is a method used to connect two or more wireless networks. This technique allows different wireless networks to communicate with each other, essentially extending the range of the original network or integrating multiple networks into a cohesive system. Wireless bridges typically connect to access points of each network and can facilitate network traffic between them, allowing resources and services to be shared effectively across the connected networks.

This method is particularly beneficial in scenarios where running physical cables between networks is impractical or cost-prohibitive. By utilizing wireless bridging, organizations can create a more extensive network infrastructure without the limitations imposed by wired connections.

The other methods listed serve different purposes. Ad hoc networking refers to a temporary network setup where devices connect directly with one another without a centralized access point. Repeater technology amplifies signals to extend the range of a wireless network but does not connect multiple networks together. Signal routing pertains to directing data packets through a network via routers, which is essential for network communication but does not specifically address the connection of multiple wireless networks.
