Why Migrate to ac Wireless AC is faster Wireless AC provides greater range, even for N devices via beam forming 70% of smartphones will be ac ready by 2015 As of June 2014, over 600 devices were certified ac by the Wi-Fi Alliance with over 375 of these being client devices Due to higher and more efficient data transmission, battery life actually increases on AC devices

How is CFCC Deploying ac Slow integration of ac into existing n infrastructure First integration points have been high volume user areas – Libraries – Cafeterias – Commons / study areas – Wireless computer labs Currently have 24 high density model ac access points deployed (Aruba AP225) All new construction will be exclusively ac
