What every wireless network has is a WAP (Wireless Access Point). A router is the best choice and you only need one computer (a laptop with a wireless Network card will do just fine)...The WAP in turn, hooks up to either your phone line or cable and then off to your Internet Service Provider so you can get Internet access. So I guess to answer your questioin, no you do not need a desktop. Just a Wireless Access Point (router) and your laptop with a wireless network card is it.

a "wireless card" is a network card that receives a high frequency signal from a wireless router or wireless access point. Same as an Ethernet Card/Network Interface Card(NIC), only wireless. A wireless Card is a network card which connects to a radio-based computer network, unlike a regular network interface controller (NIC) which connects to a wire-based network such as token ring or ethernet. A wireless Card, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A wireless Card is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A wireless Card in a desktop computer usually is connected using the PCI bus. Other connectivity options are USB and PC card. Integrated WNIC's are also available, (typically in Mini PCI/PCI Express Mini Card form).
If you possess specialized software, you can do what ever you want if you have access to the network's router.
