        I was reading today an article on the Washington Post about the annual CES convention on consumer electronics now in progress, largely virtually, that has one I think particularly interesting item there being reported and that sounds more than a mere expression of wish by some developer or group of developers working on a new idea of theirs and trying to create interest on it. Because the Washington Post is very heavily paywalled, I am coping here some excerpts, to give those reading this comment an idea of what the item in question is all about:

        CES is ushering in one of the biggest changes to wireless network tech in years. Called WiFi 6E, it’s technically a new industry standard for routers and wireless gadgets like phones and laptops. For all your apps and devices that want to stream data, it’s the equivalent of adding a whole new lane to your home’s information superhighway.

        How does that work? 6E routers and devices can access a new wireless spectrum that was previously off-limits to WiFi. If you’ve messed around with routers over the years, you might know first came the 2.4 GHz radio, then came dual-band routers that also tapped into 5 GHz (which can carry more data). WiFi 6E adds a third: 6 GHz. This new band isn’t actually much faster, but it’s far less crowded from neighbors and other devices — meaning your connection should be more reliable.

        One downside: 6 GHz signals also can’t travel as far through your house, but they’ll be extremely helpful when devices are closer together.

        To take advantage of WiFi 6E, you’ll need to buy a new router ­— look for the E, not just the 6 — as well as devices that support it. That also means, at least for a while, the 6 GHz band will be mostly used by the devices that really need all that bandwidth, like 8K televisions and new laptops. WiFi 6E could also be very useful for future mesh routers, which work as a team to spread WiFi all around your home.

        At that frequency range, centered at 6 GHz, unlike 5G telephony, E6 won’t interfere with the GPS signals, critical to many aspects of everyday modern life, and also to those signals of similar satellite positioning systems now increasingly more widely used. It is, however, unclear at this point whether they pose or not a problem to the use of radio telescopes for observation of both the nearby and deep Cosmos. As well as other of their applications, such as for Very Long Baseline Interferometry (VLBI), a fundamental technique that combines the signals of several radio telescopes to determine precisely their positions, together with the orientation and rate of rotation of the Earth (basic knowledge for exact time-keeping among other things), along with imaging objects visualizing which is otherwise beyond  any other present day technology, such as black holes and, possibly, “orphan” dark planets gravitationaly expelled from their original star systems, now wandering through interstellar space far from any star.
