+In general, user-level MAC algorithms are connected to the underlying hardware via [wiki:WARPMAC WARPMAC], which provides MAC feature commonalities to the user. For derivatives of common random-access algorithms, the user may not need to modify any of the underlying layers. However, for more clean-slate designs, additional hardware functionality may be required. The [wiki:WARPMAC WARPMAC] framework and [wiki:WARPPHY WARPPHY] interface were designed with this in mind. Modification of these sublayers to support additional features is welcome. The relationship between user-level MAC algorithms and the WARP platform support is described in more detail in [wiki:Asilomar2006_WARPMAC our publication].
 
 == Requirements for MAC ==
-In general, it is impossible to specify in full generality the information that must be shared between any possible MAC layer with any possible PHY. For example, novel cross-layer designs will require much more sharing of state information than present in the [wiki:OFDMReferenceDesign reference design]. However, a large class of PHY-MAC interfaces will share certain behaviors like triggers to begin transmission and header copy commands. With that in mind, we have created  [wiki:WARPPHY WARPPHY] as an additional layer of abstraction to the drivers of our custom peripherals. New PHYs need to recreate this to provide a common interface to existing MAC layers.
+To use the existing infrastructure as-is, the MAC layer must be random-access. That being said, scheduled-access MAC algorithms are very possible and have had some success already on WARP ([wiki:OFDMAReferenceDesign OFDMA Reference Design]). The primary example of a MAC layer that is well-matched to the underlying infrastructure is [wiki:CSMAMAC CSMAMAC], our carrier-sensing random-access MAC layer. Derivatives of this MAC are found in the lab exercises.
