It will never replace the lower bands as the range is so much less.

I don't expect 11ad will replace 11ac given the short range of 60 GHz. What I wonder is if 11ad support will someday become a check box for mainstream Wi-Fi chips--or not.

Rick, if you mean by the dominant use future , i don't think so. this search for consumer bandwidth has diminishing human performance returns. As individuals we only need 50 Mega bit second data rates, for an individual. some of us don't want to turn into data idiots. Cheers.

802.11ad will probably emerge as a complementary technology to 802.11ac ; Problem with 60 GHz is the range issue. If I remember correctly, Wilocity only claimed in-room communication with WiGig. In order to cover the whole household, 60 GHz doesn't seem to fit the bill right now. That said, 60 GHz does enable much higher bandwidth, so it is definitely useful for connecting 'wireless' peripherals to mobile workstations / ultrabooks. The big task for Wilocity (who happen to be a bit early to the party right now) is to convince the market to adopt this technology.

Is 60 GHz the future of Wi-Fi?

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
