Providing wireless connectivity at remote sites has been a challenge for organizations with distributed locations, such as retail chains and K-12 school districts, as well as service providers looking for a wireless LAN (WLAN) solution to ease congestion on their 3G/4G networks. These enterprises need robust WLAN functionality, including voice and video optimization, high reliability and strong security. They also need a solution that is affordable both to buy and to operate in a distributed environment, one that can be deployed rapidly and configured and managed centrally. Continued growth in BYOD and mobile devices is adding to the need for high-performance WLANs. In addition, hotel operators, restaurant owners, retailers, and other distributed enterprises must comply with data privacy regulations such as the Payment Card Industry (PCI) Data Security Standard and HIPAA for healthcare. Service providers also need a cost-effective wireless solution to increase the capacity and coverage of their cellular infrastructure to ensure a positive end-user experience. All of these organizations need a feature-rich, enterprise-grade WLAN that meets a variety of challenges.
