I think that that is only to distinguish it from wired access points 
I don’t know about you, but I have my Audience wired … both for PoE and for backhaul. And it only works as AP (no routing or anything else). Which it means Audience is a wired AP
i have a mantbox, am currently using it as a test indoors, but the signal strenght is’nt good at all what could be the issue.
My main focus is to provide out door coverage with the mantbox
mANTbox has a pretty narrow-beam antenna. Have a look at diagrams, published in product’s quick guide. Since Tx power is generally limited by country regulations, this means that decent signal strength is only available in directions with maximum antenna gain and elsewhere signal strength is pretty low.
Grok and ChatGPT disagree. They say “wAP” means wireless access point. I suspect Grok & ChatGPT are wrong as all access points are wireless.
When an esteemed member of MT support team says something and LLMs disagree … then in my mind there’s no doubt who to trust … And your wording (“I suspect”) makes me worry about lack of common sense … as more and more people consider LLM answers more credible than answers from people “who really should know”.
So cAP means ceiling except their own product description says “The cAP ac is a very capable and powerful wireless access point that looks beautiful on both walls and ceilings”. So even Mikrotik’s own documentation isn’t consistent.
The reason a lot of eyebrows have raised is that we’ve been merrily installing cAP ac on walls and now that practise is been questioned if half the radiation is going up to the ceiling. I’ve got one installation where the electrician didn’t put one of the cAP ac on the ceiling, it’s on a wall between rooms. One kind of assumed that the radiation pattern was unidirectional but maybe not.
As to trusting AI, I clearly didn’t trust it but I deferred from correcting it until the truth was out.
It’s the same unnecessary discussion as with the CRS series, which stands for “Cloud Router Switch.” Even though the word “router” is in the name, these devices are mainly switches, not routers. People argue a lot about whether it’s a router or not, but it’s really not important. Just look at the technical specifications and that’s it.
For example: the cAP ac has a 360° radiation pattern, so it’s suitable for mounting on a wall or ceiling. The wAP ax has a 180° radiation pattern, so it’s only meant to cover that specific area — it doesn’t matter whether you place it on a wall, ceiling, floor, or pole.
Unless you use very narrow 
degrees, more like 90-120°.
I agree that MT’s marketing and quick reference documents could be much better. Like not resorting to “poetic” descriptions when technical data doesn’t agree (“access point that looks beautiful on both walls and ceilings” versus antenna radiation patterns). And like publishing all relevant data in product brochure (in case of wireless devices, both WiFi and wireless broadband such as LTE or 5G) even if some marketing idt thinks not many users will appreciate all that info (just because that marketing idt doesn’t understand the info it doesn’t mean that no users will understand it).
But until MT docs improve signifficantly, we’ll have to grab any quality info that floats around even if not published through official channels (and IMO LLMs are not really good at noticing a gem in a heap of poop, they’ll serve poop in most cases).
the cAP ac has a 360° radiation pattern, so it’s suitable for mounting on a wall or ceiling
While it might have 360° radiation pattern in horizontal plane it’s got a very notable hole in vertical plane (along the symmetry axis). So when mounting in horizontal orientation (on a ceiling), it doesn’t matter how it’s oriented (which direction is facing e.g. RJ45 port). Because the hole in vertical radiation pattern will be “covering” ceiling and floor right above and below the device and lack of antenna gain in that direction will be offset by proximity of devices if they find themselves in those directions.
However when mounting the same device on the wall, the radiation pattern in now horizontal plane is now anything but omnidirectional. E.g. if it’s mounted at the end of a corridor on the end wall, then the hole in radiation pattern will cover the corridor itself. This might be good in some cases and very bad in some other cases. But this means it’s not really a wall AP and even if it fits use case it would be super helpful to have all radiation patterns published (all means for both planes and for all bands … ideally for 5GHz for both lower and upper end of spectrum).
I have mounted the cap ac on a wall. For comparison, I sometimes temporarily mount the wap ax instead. In terms of signal direction, the wap ax is ideally positioned to cover my apartment with its 180 degree front angle (since there is exterior wall behind it). However, the 5ghz coverage is no better than the cap ac, and the 2.4ghz coverage is worse. So, I don’t really care what kind of signal pattern the cap ac sends out when mounted on the wall - it just works.
Country regulations - EIRP limitations - won’t allow a device with directional radiation pattern to provide higher signal level than a (high Tx power) omnidirectional one - in the rirection of highest antenna gain. However, directional device will support higher uplink speeds because station Tx power has nothing to do with AP antenna gain … but Rx signal level does get improved by Rx antenna gain. At the same time interference from other directions (neighbouring APs, etc.) will be supressed a bit as well. Which all in all means that bi-directional link will be more stable.
All of the above is true in medium to high signal loss cases. If signal loss is low enough, then antenna gain difference of a few dB won’t make much of a difference.
