I come across a lot of technical literature that talks about a device being a "wireless access point/client/bridge", or "AP/client/repeater", or "AP/Client".

I understand that bridging and repeating functions are not always available for every device. But is there such a thing as a wireless access point that doesn't also serve as a client? It seems to me that the only difference between "client" and "access point" is a hard-line connection to the network, which is a question of topology and configuration, not of actual device capabilities or specifications. Thus, it seems to me that if one were to say "This is a wireless access point", prattling on about "and it's also a client" is redundant.

"Access point/bridge", that I can understand. But "AP/Client/Repeater"? or "AP/Client/Bridge"?

This is an explanation "as how I understand it" so if this is wrong please say so or edit.

In my eyes, a wireless access point can fuction as a router or such normally, but in access point mode it will only accept/distribute wireless connections and not provide any services such as DHCP or DNS. This is done over a wired connection. In "Access Point/Client" it is connecting, via wireless, to a main station and then distributing that wireless as an access point itself as well. I do this at home, in a form. We have the main family wireless device and then I have a router in Client Mode in the attic, so to the main wireless device the router appears as a normal "client" but once in the attic it re-distributes the connection (not over the wireless, however, my device is limited in that it can only act as a bridge or a normal wireless router before, it can't use the wireless to link to the main one and also can't extend the wireless network).

Yay for MS Paint!

"client" is used ambiguously by a lot of AP vendors. This is what they typically mean. –  MDMarra Dec 20 '11 at 12:16

Note that "Bridged wireless" is also called "Mesh networking" by the large enterprise wireless products. –  pauska Dec 20 '11 at 14:03
