802.11n technology for extreme performance & coverage The P-661HNU-Fx Series featuring 802.11n technology provides the ultimate solution for speed & coverage. With data rate up to 300 Mbps, P-661HNU-Fx Series provides stable & reliable wireless connections for high speed data & multimedia delivery. It eliminates dead zones & extends coverage by using IEEE 802.11n technology & is backward compatible with any IEEE 802.11b/g Wi-Fi certified device. Wi-Fi Protection Setup Wi-Fi Protected Setup (WPS) is a standard for easy & secure establishment of wireless networks. With WPS, the device will automatically configure a wireless network with a network name (SSID), strong WPA data encryption & authentication. WPS makes the configuration of secure personal wireless networks as simple as pushing a button or entering a Personal Identification Number (PIN) code. SPI Firewall & IPSec VPN The Stateful Packet Inspection (SPI) Firewall works on the network layer by examining header & footer of a packet, & it also ensures the packet belongs to a valid session. Based on SPI, Denial of Service (Do S) & DDo S features, the P-661HNU-Fx Series provides the first-line defense against hackers, network intruders & other harmful threats. Besides, P-661HNU-Fx Series allows companies to establish Virtual Private Network (VPN) connections with business partners, as well as remote & branch offices. VPN uses data encryption & the Internet to provide transparent, secure communications between two or more sites without the expense of leased site-to-site lines. The P-661HNU-Fx Series provides VPN connection with IPSec technology. TR-069 remote management With TR-069 standard management specifications, service providers are able to manage & configure client devices remotely without manual intervention from end users. This unique feature not only offers true “plug & play” experience but also reduces the complexity of deployment, & therefore saves operating & maintenance costs for service providers. 3G WAN backup support With the built-in USB (Universal Serial Bus) interface for a 3G dongle, the P-661HNU-Fx Series can offer you the flexibility to share either a 3G WAN or a x DSL connection with all users in your network when either connection is available without any configuration required.
