The Wireless-N WRVS4400N Gigabit Security Router with VPN implements draft IEEE 802.11n (Wireless-N) technology with a Virtual Private Network (VPN) Router that features a built-in 4-port full-duplex 10/100/1000 Gigabit Ethernet switch. By overlaying the signals of multiple radios, Wireless-N's "Multiple In, Multiple Out" (MIMO) technology multiplies the effective data rate resulting in greater than 100 Mbps throughput and at least twice the range of Wireless G.
