att_abstract={{In this paper, we present an  experimental and simulation based study to evaluate the use of full-duplex as a mode in practical IEEE~802.11 networks. To enable the study, we designed a 20~MHz multi-antenna OFDM full-duplex physical layer and a full-duplex capable MAC  protocol which is backward compatible with current 802.11.  Our extensive over-the-air experiments, simulations and analysis demonstrate the following two results. First, the use of multiple antennas at the physical layer leads to a higher ergodic throughput than its hardware-equivalent multi-antenna half-duplex counterparts, for SNRs above the median SNR encountered in practical WiFi deployments. Second, the proposed MAC translates the physical layer rate gain into near doubling of throughput for multi-node single-AP networks. The two combined results allow us to conclude that there are potentially significant benefits gained from including a full-duplex mode in future WiFi standards.}},
