The main objective of IEEE 802.11ac is to increase the throughputs of the previous IEEE 802.11 standards. Compared to IEEE 802.11n, the draft of IEEE 802.11ac allows for eight antennas (11n: four), 256-QAM modulation (11n: 64-QAM), and channel bandwidths of up to 160 MHz (11n: 40 MHz). The changes in the standard allow for a theoretical throughput of up to 7 Gbit/s. The LDPC codes are the same as in IEEE 802.11n.
