Standards are put in place to make everything work together error free. Because Stability, Consistency, Minimization of packet errors.
Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult.
Hospitals, security systems, PA & recording studios.
The drawback of STP cables is that they will increase the total cost of an installation. STP cables are more expensive due to the shielding, which is an additional material that goes into every meter of the cable.
The shielding also makes the cable heavier and stiffer. Thus, it is more difficult to handle.
