/**
* \brief Ideal rate control algorithm
* \ingroup wifi
*
* This class implements an 'ideal' rate control algorithm
* similar to RBAR in spirit (see <i>A rate-adaptive MAC
* protocol for multihop wireless networks</i> by G. Holland,
* N. Vaidya, and P. Bahl.): every station keeps track of the
* snr of every packet received and sends back this snr to the
* original transmitter by an out-of-band mechanism. Each
* transmitter keeps track of the last snr sent back by a receiver
* and uses it to pick a transmission mode based on a set
* of snr thresholds built from a target ber and transmission
* mode-specific snr/ber curves.
