Impact of clock drift on wifi
Witryna10 mar 2024 · New Wi-Fi generations have increased the modulation constellation size with 1024-QAM and 4096-QAM, placing an even higher requirement into transmitter … Witryna27 kwi 2011 · 6. If you average 5 drifting clocks, the only thing you get is another drifting clock that's harder to correct. It won't be more precise. NTP uses multiple servers to increase precision because it takes network latency into account. Since all your systems are on a fast local network, you just need one server.
