There are many things that can influence your decision. This is an outdoor connection, how "free" is the 2.4GHz spectrum there?
SIgnal that is very low indoors, might be there and interfere outdoor. What are the requirements for speed?
Essential characteristic in the wireless PtP solution is the directional antenna. (Groove52 is omnidirectional)
Just as an example ...
What I do for this, is mounting 2 "SXTsq 5 ac" on the outside wall's, pointing to each other and using "bridge" and "station bridge" mode. To serve the clients a hAP/cAP/wAP is used. (e;g. hAP ac2).
The indoor units are 1Gb ethernet wired connections to the SXTsq.
I know this is a luxury solution, with a very high speed connection.
Many alternatives are possible , like a SXTsq 5 Lite, and a hAP ac Lite (with PoE out built in).
Like combining the AP and PtP in one device. (The requirements are a trade off between the 2 functions). Just a wAP ac outdoor at the garage?
Even if your garage is on another circuit the PWR-Line might still work. (Unless it is 3 phase electrical provisioning, with a different phase to the garage.)
