Solution
The physical layer technology with the highest transmission rate and lowest bit error rate in practice is the Fiber optic cable. This is because fiber optic cables have a much higher bandwidth compared to twisted pair cables, 4G/5G cellular, coaxial cables, satellite channels, and 802.11 WiFi Channels. They can carry more data over long distances and are less susceptible to interference and signal degradation, resulting in a lower bit error rate.
