Abstract: Logic may transmit or receive communications that hop frequencies in response to trigger events across a large bandwidth. Logic may generate a communication with a contiguous or non-contiguous bandwidth based upon frequency segments of 80 and/or 160 MHz. Logic may generate a communication with a contiguous bandwidth of 480 MHz. Logic may generate a communication with a non-contiguous bandwidth of 480 MHz. Logic may transmit or receive communications with a 480 MHz bandwidth that hop across a 3 GigaHertz (GHz) bandwidth of frequency channels. Logic may determine a channel-hopping pattern. Logic may hop frequency channels after each link transmission. Logic may hop channels after a fixed time interval. And logic may hop frequency channels in response to another triggering event.
