BT have made some interesting claims regarding their WiFi, with the latest being that it is the "most powerful".
Now this is a rather odd claim as "power" is not something that is all that relevant - power (measured in Watts) is not that helpful as a measure of WiFi, indeed many smaller APs with lower power can (I believe) provide a better coverage and performance. Saying you have the most powerful WiFi is like saying your house has the brightest street light outside it. The main impact being it will make other WiFi nearby worse.
BT have made all sorts of claims before, all of them (in my view) rather suspect. The claim of most powerful WiFi, when WiFi is a radio data system to strict international and national agreed standards, is rather odd. The WiFi will have the power within the standard and legislation, like any other WiFi. It cannot in practice be more powerful.
They even published a document to justify the claim (here).
First issue: "The BT Smart Hub has superior specifications than the routers of all major broadband providers". So only most "powerful" if you ignore the smaller providers. They only look at "major" providers. AAISP have been offering Unifi APs and packs of multiple Unifi APs for some years now, but that does not count as not a "major" provider.
Second issue: The comparison compared many things but not one of them was in fact "power"! They state: "The most important aspect of wi-fi for customers is their Transmission Control Protocol (TCP) throughput.". Whilst this is actually a quite good metric, it has absolutely nothing to do with the claim of being most powerful. Power is in Watts and is not a measurement of download speed.
Third issue: They actually tested the WiFi. This is good as that is what they are claiming is most powerful, but they are selling an "Internet Access Service" using this. The tests are nothing to do with Internet access (you can tell from the speeds they measured) and for most people any speed on the WiFi that is over the speed of their Internet Access is irrelevant, so no help. Yet the advert is to sell Internet Access, not simply WiFi APs.
Basically, they are simply claiming they have a good 3x3 antennae single AP WiFi system they sell/provide with the Internet access system they sell and that it is somehow more "powerful" than other ISPs. They ignore the other (smaller) ISPs selling systems just as good. They ignore those selling multiple access point solutions which are better. They ignore all of the non ISPs also selling this equipment. And they ignore that the actual "power" is the same on these devices and their claim of most "powerful" is not actually about "power" at all but TCP throughput.
Anyway, yes, consumers want an Internet access service that is good. If BT are "most powerful" in that, why are many ISPs (including AAISP) way higher in ispreview's list? (here)
