Sure, the more precise term is Point-to-Point (PtP Bridging). It's basically where one specialized access point talks to another access point. It's used for nothing else other than that purpose.
Nowadays, we have companies like Ubiquiti that make very affordable outdoor bridges. The main purpose of these is to provide an alternative to running direct lines between locations that need site-to-site capability. Before it was around, people used to just have T1 lines or more. Really expensive.
