According to this article below, 160mhz or (80+80) is a requirement of wave 2. http://www.cisco.com/c/en/us/solutions/collateral/enterprise-networks/802-11ac-solution/q-and-a-c67-734152.html
*"However, given that 160 MHz of relatively unused contiguous spectrum is difficult to find, there is an 80+80-MHz mode, which is simply the 160 MHz waveform split into two different 80-MHz frequency segments, enabling them to be placed more flexibly."* Would imply that adjacent channels is not necessary. You could bond a UNII-1 (80mhz) and a UNII-3 (80mhz) to create a 160mhz channel.
