KEY BENEFITS
(CONTINUED)
STANDARDS-BASED FOR INTEROPERABILITY
The 3Com Wireless 11n Cable/DSL Firewall Router uses IEEE 802.11n
draft 2.0 technology to deliver significant wireless speed and range
improvements over IEEE 802.11g networks. With two external and one
i
nternal antennas and advanced Multiple Input Multiple Output (MIMO)
technology, the enhanced wireless range of this router helps provides
single point coverage in small office and home networking environments,
and can eliminate dead spots common with other wireless LANs.
HIGHLY-EVOLVED SECURITY FEATURES
A
dvanced wireless security and multiple firewall features offer high
levels of protection for the network. To help shield wireless connections,
this router provides 128-bit WPA/WPA2 with TKIP/AES encryption that
encodes and protects information, providing maximum security. For
legacy clients, WEP encryption is also supported.
URL filtering, a Stateful Packet Inspection (SPI) firewall with hacker
pattern detection and other security features help protect the entire
network from attacks and other Internet security risks. Support for
initiation and termination of Internet Protocol security (IPSec) tunnels
helps enable security between business sites.
ADVANCED QUALITY OF SERVICE (QOS) FOR QUALITY-SENSITIVE
INFORMATION TRANSFER
A unique combination of features helps assure reliable delivery—with
no interruption—of delay-sensitive information like voice and video.
RELIABLE, SIMPLE TO USE AND GREEN
Designed to meet 3Com’s proven standards of quality, reliability is
assured and supported by a two-year hardware warranty. A browser-
based user interface and simple setup wizards ease installation,
configuration and administration.
All-in-one design integrates four functions— .11n access point, 4-port
switch, firewall and routing—into one product, simplifying deployment.
With the push of a button, Wi-Fi Protected Setup
™
(WPS) is easily
enabled, automating and simplifying the creation of a secure wireless
network. Other features like a Wi-Fi “on-off” button make this product
easy-to-use while also reducing power costs.
