It is possible to connect a "wireless bridge" (i.e. a wireless router or access point set to the "bridge" mode) to the wired NIC of a PC. The PC then netboots through the wired Ethernet NIC as usual, but the data is then transmitted from the NIC to the wireless AP/router connected to it and then wirelessly "across the bridge" to a central wireless access point/router.

This solution works reasonably well but requires two wireless access points/routers (one on each side of the "bridge") making it a more expensive solution. It is sometimes, however, easier than running extra Ethernet cables throughout a building.
