Shortly after IEEE 802.3bw was finalized, the IEEE officially ratified the 802.3bp standard, or 1000Base-T1, which enables gigabit-level speeds over shielded or unshielded twisted-pair cables. This standard shares a lot in common with its predecessor, but the frequency is nearly 10 times higher, at 600 MHz. This means that cables are more susceptible to crosstalk, so engineers need to take special care when designing systems to control electromagnetic noise throughout the vehicle, rigorously test them and shield them when needed. This standard will provide enough bandwidth for the next two to three generations of platforms.
