Model 5363 combines a Comcast and Time Warner Cable certified 343 Mbps DOCSIS 3.0 8x4 Cable Modem with a very high-performance 1900 Mbps 802.11ac Wi-Fi Router with 4 GigE LAN ports. The 5363 is certified for money-saving own-your-cable-modem programs by Comcast and TWC. The 5363's wireless networking features are the best in the industry and include 3x3 internal antennas for both a "1300 Mbps" 802.11ac/a radio operating at 5 GHz and a "600 Mbps" 802.11n/g/b radio operating at 2.4 GHZ. Speed and range are supercharged by wireless beam forming for both 2.4 and 5 GHz radios. Beam forming focuses Model 5363's wireless energy on each wireless device. 11ac beam forming is used when connecting to 802.11ac clients. Even better, Broadcom Any Beam is used when connecting to ANY other 2.4 or 5.0GHz wireless client even if that smartphone, computer, tablet, smart TV or other Wi-Fi compatible device doesn't have beam forming technology. Wireless performance is also boosted by Broadcom TurboQAM technology to increase maximum wireless-N data rates at 2.4 GHz to 600 Mbps, 33% over competitors without this feature. Beam forming, dual wireless radios, and 3x3 antennas for both radios provide a significant advantage, especially in locations with interference from nearby wireless networks. Model 5363 is certified by Comcast, TWC, and Cable Labs to support DOCSIS 3.0 and IPv6, operating at 343 Mbps downstream, 123 Mbps upstream. DOCSIS 2.0 and 1.1 are also supported.
