802.11ac Wave 2
Channels for wave 2 products would mostly move from 80-MHz (at the high end for Wave 1) to 160-MHz (80+80) bonded channels. Moving up to 160-MHz is good for bandwidth since it is similar to adding more lanes on a highway. Theoretically using 160-MHz bandwidth means more users can be supported with better performance. However, operating at 160-MHz requires a clear channel and may mean that most AP’s continue to use both 80-MHz and 40-MHz, even through the wave 2 switch.

Data rates for wave 2 products are expected to average around 2.5 Gbps, but real life may even be lower.
