If they’re anything like the Verizon 5G gateways in the US that go in the window, then yes they’re great. So long as they use mmWave ultra wideband, and you have direct line of sight to the tower, they’re as good as a wired connection IMO. I get 1400Mbps both ways; literally maxes out my gigabit lines and I have to use wifi to hit those speeds. Latency is good enough to play competitive shooters too. I absolutely love it. And for only $50/mo it’s literally twice as fast as cable for half the price.
