High-Speed Wireless Access That Extends Network Connectivity


• Supports high-bandwidth applications with the 802.11n standard; backward compatible with 802.11b and g devices

• Connects to Power over Ethernet devices, simplifying installation and eliminating the need for and cost of installing external power supplies

• Protects business information with enhanced security, including rogue access point detection, advanced encryption, and select access filters

• Increases wireless throughput and range and expands the range to reduce "dead spots" in the wireless coverage area with MIMO technology

• Simplifies installation and configuration with easy-to-use web interface

Product Overview

With the growth in high-bandwidth applications, such as storage and video, in the workplace, network performance is essential. Wireless technology is no longer lagging behind wired performance. The Cisco ® WAP4400N Wireless-N Access Point (Figure 1) answers the growing business need for access, speed, and security.
The Cisco WAP4400N uses the latest wireless networking technology, Wireless-N (draft 802.11n). By overlaying the signals of multiple radios, Wireless-N's multiple-input, multiple-output (MIMO) technology multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area.
The Cisco Wireless-N Access Point lets you connect Wireless-N (802.11n), Wireless-G (802.11g), and Wireless-B (802.11b) devices to your wired network, so you can add PCs to the network with no cabling hassle. Power over Ethernet (PoE) support makes the access point easy to install - you can mount it anywhere, even without ready access to a power plug. With appropriate PoE support at the other end, you need to run only one cable to the access point to deliver both data and power. Of course, you can also use the included AC adapter if power is available nearby.
Moreover, the integrated quality of service (QoS) features provide consistent voice and video quality on both the wired and wireless networks, enabling the deployment of business-quality voice over IP (VoIP) and video applications.
To protect your data and privacy, the Cisco Wireless-N Access Point supports both Wired Equivalent Privacy (WEP) and the industrial-strength wireless security of Wi-Fi Protected Access (WPA), encoding all your wireless transmissions with powerful encryption. The MAC address filter with advanced logging lets you both control and stay apprised of who accesses your wireless network. Configuration is a snap with the web browser-based configuration utility.
The Cisco WAP4400N Wireless-N Access Point is the best way to add wireless access to your existing business network.
