What is the difference between Category 3 and 5e cabling?
Category 3 is specified up to 10 Mbps at 16 MHz and is typically used for voice and slower data applications. Category 5e is faster, specified up to 1000Mbps at 100 MHz. Typically used for high speed data transmission, Category 5e is also acceptable for voice applications. Category 5e can be used with 10Base-T, 100Base-T and Gigabit Ethernet networks.
