CAT5e and CAT6 are commonly used ethernet cables for data transfer, offering speed, reliability, and shielding to protect their copper wiring from interference. Both types support speeds up to 1000 Megabits per second (1 Gigabit per second), significantly faster than most existing wireless connections. The primary distinction lies in their bandwidth capacity: CAT6 boasts a higher threshold, enabling simultaneous transfer of larger volumes of data compared to CAT5e.
