Testing Very High Throughput (VHT) 802.11ac Signals
With wireless LAN becoming the primary connectivity choice for a growing array of consumer, commercial and industrial systems, wireless standards keep evolving to provide the data rates needed to support this migration away from wired networking. The next enhancement to the 802.11 standard will be Very High Throughput (VHT) 802.11ac, scheduled to be finalized by the beginning of 2014.
Major changes in 802.11ac
Moving well beyond the 100 Mbit/s speed of 802.11n, 802.11ac specifies a minimum 500 Mbit/s single link and 1 Gbit/s overall throughput, running in the 5 GHz band. And in contrast to the 20 MHz channel bandwidth of earlier variants, 802.11ac mandates an 80 MHz bandwidth, with optional wider bandwidths of 160 and 80+80 MHz. See Figure 1.
