The router's MIMO (Multiple Input, Multiple Output) technology makes it a natural choice for multimedia fans, minimizing errors and optimizing data speed through multiple antennas for both sending and receiving. It's compliant with Draft 802.11n, for the best possible wireless technology available today offering greater range and data speeds than the older 802.11b/g standards, (when used with compatible Draft 802.11n wireless adapters) while still being fully backwards compatible with them—perfect for mixed-mode environments. You'll find advanced firewall and intrusion prevention (IPS) features to secure your network from external threats, including worms, DDoS attacks, and viruses and the ability to create virtual-private-network (VPN) so mobile workers can securely connect to your business network. Combine security and speed into a sweet expereince!
