Maximum PC - - WI-FI -

We’ve talked about the 2.4GHz and 5GHz wave­lengths ex­ten­sively, which should be enough for any­one, but there is a third: 60GHz. If you’ve never heard of Wire­less Gi­ga­bit, or WiGig, we don’t blame you. It sprang up about a decade ago, aim­ing to uti­lize the un­li­censed 60GHz wave­length, and de­velop a wire­less gi­ga­bit stan­dard. We thought noth­ing came of it; there were talks and demon­stra­tions of wire­less HDMI and USB, but noth­ing that seemed to catch on.

The at­trac­tion of 60GHz is that it’s freak­ing fast. The 802.11ad 60GHz stan­dard de­liv­ers 4.6Gb/s on one chan­nel, and po­ten­tially four chan­nels can be bonded to­gether. The down­side: 60GHz can’t pen­e­trate phys­i­cal bar­ri­ers, so we’re talk­ing same­room or even samedesk net­work­ing. It could be awe­some for VR 4K wire­less head­sets, but you’ll have to fig­ure out how to get that net­worked.

It’s likely this is what stopped 60GHz prod­ucts be­ing widely rolled out. So­lu­tions have been around since 2014, and the odd Wi-Fi router ap­peared in 2016, but the ad­di­tional con­fu­sion and com­plex­i­ties have seem­ingly put off man­u­fac­tur­ers. Per­haps we’ll fi­nally start see­ing wider use of 60GHz in 2019....

Brace your­self: A new Wi-Fi stan­dard is com­ing....
