Wireless Connection Future Challenges : Office: Multiple Gadget. 10Mb per user. Home: Home Automation, UHDTV, Multiple Gadgets Schools: K-12, E-Learning Hospitals: IP based Equipment. Centralize Hospital Records. E- Consultation. Utility/Agencies: IP Based devices, Real time HD video reporting. Wireless CCTV Convention: 1000’s of users with tablets, smartphones, laptops,… Airport: Crazy

Shannon’s Law states that the maximum attainable error-free data speed, in bits per second (bps), is a function of the signal-to-noise ratio and bandwidth. C = B log2< (1 + S/N)
17
MIMO How fast is 2x2 and 3x3 11ac? 2x2 = up to 867Mbps data rates per radio 3x3 = up to 1.3Gbps data rates per radio 11ac is about 3X faster than 11n
18
Wi-fi performance is limited by the device Most BYOD clients are 1x1 or 2x2 and cannot take advantage of 3 streams in a 3x3 Wi-Fi infrastructure Device2.4GHz5GHzAntennasMax Rate Media Players (iPod Touch)XSome1x165-150Mbps Smartphones – low endX1x165Mbps Smartphones – high endXX1x1150Mbps Tablets – low endX1x165Mbps Tablets – high end (iPad)XX2x2300Mbps Laptops – low endXMost2x2300Mbps Laptops – mid/high endXX3x3450Mbps Most BYOD clients are 1x1 or 2x2 and cannot take advantage of 3 streams in a 3x3 Wi-Fi infrastructure
