VEXnet vs. 802.11b/g
VEXnet uses 802.11b/g as a low cost radio with worldwide compliance. VEXnet does not implement all the excessive features that 802.11 provides for wireless communication between PCs, through wireless access points, or through the internet. VEXnet simply uses 802.11 for a simple point to point communication system. Future versions will implement multi-robot communication features.
