In today's dynamic business environment, employees are becoming more mobile and collaborative than ever. To stay productive, they need dependable, business-class access to network applications throughout the office. The Cisco Small Business 500 Series Wireless Access Points provide a simple, cost-effective way to extend secure, high-performance mobile networking to your employees and guests, so they can stay connected anywhere in the office. This flexible solution lets you connect dozens of employees, and can scale to accommodate additional users and changing business needs.

The Cisco 500 Series access points use selectable or concurrent dual-band radios for improved coverage and user capacity. Gigabit Ethernet LAN interfaces with Power over Ethernet (PoE) support flexible installation and reduce cabling and wiring costs. Intelligent quality-of-service (QoS) features let you prioritize bandwidth-sensitive traffic for voice over IP (VoIP) and video applications. SmartSignal Antenna technology enables you to extend the reach of your wireless network by optimizing coverage, reception, and performance.

To provide secure guest access to visitors and other users, the Cisco 500 Series access points support a captive portal with multiple authentication options and the ability to configure rights, roles, and bandwidth. A customized guest login page lets you present a welcome message and access details, and reinforces your brand with company logos.

The Cisco 500 Series access points are easy to set up and use, with intuitive wizard-based configuration to get you up and running in minutes. An attractive design with flexible mounting options enables the access points to smoothly blend into any small business environment.

To enhance reliability and safeguard sensitive business information, the Cisco 500 Series access points support both Wi-Fi Protected Access (WPA) Personal and Enterprise, encoding all your wireless transmissions with powerful encryption. In addition, 802.1X RADIUS authentication helps keep unauthorised users out.

Designed to scale smoothly as your organization grows, the access points feature controllerless Single Point Setup that simplifies the deployment of multiple access points without additional hardware. With the Cisco 500 Series access points, you can extend business-class wireless networking to employees and guests anywhere in the office, with the flexibility to meet new business needs for years to come.
