CP210 or CP510 radio directionality
CP210 or CP510 radio directionality
I'm planning to set up two CP510 devices to connect a barn to my house. I was planning on setting up the house CP510 as an access point, but I'm unsure about the mode for the barn. I'd like to be able to connect devices in the barn both with wired ethernet and wirelessly, without using an additional wifi router. From the documentation, it appears that the correct mode for this use is AP Client Router.
However, I'm concerned about the directionality of the radio. I know that the primary radio and antenna are very directional, which allows the CP510 to communicate over long distances to the house access point. But the documention is unclear about how the local wifi access in the barn will work. Is there a second radio in the device that provides omnidirectional local access to the CP510? Or does the local wifi network share the same radio and antenna, which would mean that wireless devices in the barn would have to be in the directional path towards the house?

Note that in your first diagram, which I've seen in the manual, it shows "User Network" and has wifi symbols indicating a local connection to wifi devices. This is what I was finding confusing. According to that diagram, and the documentation, the device IS designed to support a local wifi network.
Yes, Pharos supports MASTER mode in addition to STA mode in Bridge, Repeater, AP Router and AP Client Router operation modes.
But it's not a »local wireless network«, it's still a directional long-range wireless network, albeit the CPE is in MASTER (AP) mode. Setting this mode doesn't change the antenna. What's more, a CPE in AP mode is not necessarily »repeating« what the CPE receives wirelessly in STA mode from another AP.
Also keep in mind that CPEs are not the only Pharos products. There are WBS, too, and they have all kinds of antennas, omnidirectional, directional, sector, dish etc.
There are situations where directional AP mode could make sense, e.g. to get around a corner, albeit a more common trick in directional RF deployments is the use of a metallic structure or a building to have them reflecting the wireless signal into a desired direction.
But it is still a directional signal in case of CPEs, not a local (omnidirectional) WLAN suited for feeding standard clients.
You can't beat physics with software.
