Logic may determine a first frame comprising a hopping pattern value and a target hopping time (THT). The hopping pattern may indicate a pattern of channels to which to hop. Logic may determine a clear-to-send (CTS) frame comprising a duration value indicative of a duration of a data transmission. Logic may transmit the first frame on at least a primary channel of the channels. Logic may transmit the CTS frame prior to transmitting the data transmission on the one or more channels in accordance with the hopping pattern, each channel having a bandwidth of at least 450 megahertz and being within in a 6 gigahertz to 10 gigahertz frequency band. Logic may receive a frame on at least a primary channel of the channels. Logic may receive CTS frames at the THT in accordance with the hopping pattern.
