I want to extend the wireless network in my house.
Unfortunately I cannot run cables around so I have to do with WDS.
I have done tests with cAP I have access to, and found out that the only two points I can position them are too far apart. There are three thick brick walls, and the signal goes down to -85/-90 giving me just 3 Mbps of throughput.
I was thinking of using some more directed antennae to establish the point to point link and maybe connect two AP to them without WDS.
You need more powerful radios. Take something with 2hnd. But better is not to use wds. Use cable even if you can’t. Or at worse use some device with two radios, one as client and other as ap and bridge them.
Would I need something with directional antennae? Like the SXT line?
Also I see that many boards only have L3 license. Could I use them to connect point to point or would I need one of them to be L4?
If I could use cable I’d just get 3 AP and that would be it
Seems good. But what devices have two radios? Do they also have dual bandwidth, so I could do the point to point over 5Ghz and the AP on 2,4?
You can use L3 device like sxt as client and other L4 device as ap. You can use two L3 devices as wireless bridge. There is no device with two radios sold as is but you can add second (or even more) radio card to some of them. For example netmetal, basebox, 912, 922, 433, 435, and others. Final solution depends on your throughput needs and local situation. 2.4ghz has better penetration thru the obstacles than 5ghz.
Have you thought about HomePlug AV as a solution to placing AP’s in remote locations within the property without additional wiring.
Use PiggyBack HomePlug units if you can get them (better filtering) and consider using the newer AV2 units which utilise mimo to get the best speeds (or stability with poor cabling/longer runs).
