The bandwidth and application performance you need to support all of your users 802.11ac technology builds on the advances of 802.11n - the 802.11ac radio delivers more bandwidth and faster speeds through technology enhancements such as Multiple-Input Multiple-Output (MIMO). 256 QAM modulation gives the MIMO 802.11ac radio an additional performance boost and increases the bandwidth of the 802.11n radio to 802.11ac speeds. In addition interference from 2.4 GHz devices is finally eliminated. Since 802.11ac operates only in the 5 GHz band Bluetooth headsets microwave ovens and other devices will no longer impact Wi-Fi network performance. The result? Your WLAN can support an unprecedented number of users and applications. More robust wireless connections Your users will experience a wireless connection than ever before thanks to improved beam-forming. Beam-forming creates efficient path for data transmission between an access point and a mobile device. Until now the transmitting beam-former worked alone to define this path. Now the receiver also assists a process known as sounding. The result is a stronger connection that enables faster data transmission. Application throughput and performance is improved along with mobile device battery power. Voice locationing and guest access Support for Voice-over-wireless LAN (VoWLAN) quality of service (QoS) ensures quality even with many simultaneous calls on a single access point. In addition you can leverage locationing services to locate and track people and assets as well as control network and application access. And since you can ensure that users are only able to access authorized networks sites and applications it's easy to provide hotspot and guest access..
