wAP is an outdoor/indoor omnidirectional AP. Good for delivering wifi connection to clients.
I know that different vendors promote their "strong" AP's as links to the next AP, but that is not a very good solution.
(The "strong" TX power might be only there at illegal settings, and being omnidirectional there is a huge loss in the unintended directions)
Even an Omnitik has a better antenna spectrum (and gain) but is still omnidirectional.
The AP to AP link requirements are quite different from the AP-client requirements.
Depending on the distance you must select what you need. E.G. I use 2 "SXTsq 5 ac" and then a regular AP (like cAP, hAP, wAP) for the clients. Advantage is that you can use different channels for the link and for the clients. But many hardware combinations are possible, so maybe one SXTsq will do pointing to the AP in the shed, to make a good link.
Not all the combination are in this list.
But you can count with the antenna gain in the specs for making the link. wAP-wAP would be 2+2=4dBi, SXTsq 5ac + wAP would be 2+16=18dBi, Omnitik + wAP is 7.5+2=9.5dBi
(There are also sector antenna if you need multiple links) I also use "SXT SA 5 ac" with multiple "SXTsq ac".
6dBi more gain will double the supported distance for a certain interface speed (MCS level)
