Hi guys,

Since the new RB953GS-5HnT is a single-chip QCA9558 solution, it supports 3-chain 802.11n at 5GHz:

In many access points, the QCA9880 chip is paired with this to give 3-chain 5GHz 11ac, and clearly when Mikrotik supports it on a mini-PCIe card, we can upgrade to dual-channel 11n + 11ac.

The obvious question is, can we run the QCA9558 at 2.4GHz? If so, what is the performance impact of the onboard antenna connector spacing being 15mm, when the half-wavelength is ~60mm at 2.45GHz; this would obviously multi-path diversity. It's just a pity to not use the ample spacing on the side to optimise diversity as in other designs.

I'm ordering as soon as available, so what casing will it use?

Many thanks!
Daniel

RB953GS-5HnT has only 5ghz onboard radio, so no support for 2.4ghz.
You can put additional mini-pcie 2.4ghz card like R11e.

Can you answer why did you change connector to SMA not RP-SMA ? or even MMCX ? how to connect this board this days - i can't find any reason to do this.
