Depends on what you mean by 'extended'.

That depends entirely on what sort of antennae are used, at either end,
and what obstructions there are between access point and clients.  With
a pair of high-gain directional antennae pointing at one another with
clear line of sight, some tens of km.  High-gain directional antennae
pointing at a high-gain omnidirectional access point antenna, some km.
Indoors or through stands of vegetation (or people :), not far at all. 

The free online book, 'Wireless Networking in the Developing World', at
http://wndw.net/ should provide practical answers to your questions.
