A little more info on the above schema and why it works better than "Wi-Fi".
When properly configured, the radios communicate with each other using proprietary protocol and a frequency width that optimizes throughput, increases range and minimizes interference.
Your everyday 2.4GHz and 5Ghz wireless routers and access points do not utilize such methods because of lack of compatibility with laptops, smartphones, TV's, IoT devices, etc.
Other vendors of such radios (TP-LINK, Engenius, MikroTik, Cambium and many, many more) offer similar radios with competitive performance and prices that also use proprietary protocol for the same reasons as the Ubiquiti and primarily in PtP Layer 2 Transparent Bridge or PtMP (Point to Multi-point) scenarios. I use Ubiquiti because they have been very dependable and affordable.
I know that most of the Ubiquiti radios can be re-configured to also be compatible with the aforementioned laptops, smartphones, TV's, IoT devices, etc. but the performance and integrity of the wireless bridge would be degraded. Besides, one can install a wireless access point or a wireless router configured to "AP" mode (static IP, DHCP disabled) at the station (remote) end to provide compatible "Wi-Fi" for those laptops, smartphones, TV's, IoT devices, etc.
