Off late the UC Berkeley TIER Project studied the need to deploy network infrastructure to emerging regions. Their goal was to "Address the challenges in bringing the Information Technology revolution to the masses of the developing regions of the world". Out of that work came plans for WiFi Based Long Distance Networks (WiLDNet) that leveraged commodity 802.11 wireless parts to preserve cost savings. WiLDNets were specifically intended for deployments where station separation far exceeded normal 802.11 use (e.g. 30-100 kilometer station separation). A key component of the WilDNet design was the use of a Time Division Multiplex Access (TDMA) MAC in place of the standard DCF MAC that is part of the 802.11 specification.
