19 Wi-Fi Client Capacity- Reality = 2.4GHz = 5GHz 300Mbps 65Mbps = 2.4G and 5G 300Mbps Max 65Mbps 300Mbps = 2.4G and 5G 65Mbps Max 13Mbps 52Mbps = 2.4G only 65Mbps Max 52Mbps 45Mbps 13Mbps 6.5Mbps 120Mbps 13Mbps In a Wi-Fi network, the user data rates varies with distance, device type, Wi-Fi band, and interference

20 Advantage of 11ac Its all about Improving the high end Gigabit speeds (1-7) and growing HD Video, Imaging, Backhaul, Offload, backup Its all about improving the Low End Improved link speed Mbps Improved overall network aggregated performance Up to 6x more power efficiency Its all about improving BYOD service (handhelds) Carriers (MWC) pushing for 11ac capabilities- move to 5Ghz (Wi-Fi offload) Apple is expected to "rapidly deploy" in APs And notebooks later this year.

23 Hotspot 2.0 NGH, Passpoint, Wi-Fi Off-load

cellular access, authentication and roaming methods Output of the Hotspot 2.0 task group is the Hotspot 2.

24 What is Hotspot 2.0? Task group formed in 2010 by the WFA Goal of Hotspot 2.0 initiative is to develop a set of standards that will simplify the Wi-Fi end-user experience by emulating cellular access, authentication and roaming methods Output of the Hotspot 2.0 task group is the Hotspot 2.0 Certification Program which is intended to insure authentication and roaming interoperability among equipment vendors and service operators

25 Hotspot 2.0 Objective Make Wi-Fi as seamless and secure as Cellular Cellular Hotspot SP subscriber turns on his phone 1. Wi-Fi subscriber comes to AP of Home SP 2. Gets cellular service automatically 3. Secure connection Cellular Device Cellular Tower (Home SP) 2. Gets Wi-Fi service automatically 3. Secure connection Hotspot 2.0 STA (single or dual-mode) Hotspot 2.0 AP (Home SP) 1. SP subscriber comes to roaming partner 1. Wi-Fi subscriber comes to AP of Roaming Partner 2. Gets service automatically 3. Secure connection Cellular Device Cellular Tower (Roaming Partner) 2. Gets Wi-Fi service automatically 3. Secure connection Hotspot 2.0 STA (single or dual-mode) Hotspot 2.0 AP (Roaming Partner) Automatic and Secure Automatic and Secure

26 How Hotspot 2.0 Works

27 Hotspot 2.0 FEATURE Requirements IEEE u Network Discovery Generic Advertisement Service (GAS) Access Network Query Protocol (ANQP) WPA 2-Enterprise Encryption EAP-Based Secure Authentication

28 Hotspot 2.0 FEATURE Requirements Provides network discovery and selection Both the client device and Wi-Fi APs must support u for it to work Uses GAS (Generic Advertisement Service) to advertise which Wi-Fi networks are available to the mobile device prior to authentication Note: with GAS, the Wi-Fi AP is responsible for relaying the mobile device s query to a server in carrier s network and for delivering the server s response back to the mobile device Uses ANQP (Access Network Query Protocol) enables mobile device to discover hotspot operators domain name, roaming partners, credential type and EAP method used for authentication, IP address type (IPv4 or IPv6) and other data that can be used by the mobile device to select the best available network

29 WPA-2 Enterprise WPA-2 Enterprise certifies that wireless equipment is compatible with the IEEE i standard WPA-2 Enterprise formally replaces Wired Equivalent Privacy (WEP) and the other security features of the original IEEE standard WPA2-Enterprise certification is required to support the additional mandatory security features of the IEEE i standard that are not already included in WPA.

30 Extensible Authentication Protocol (EAP) EAP is a general protocol used for authentication between a mobile device and a WLAN With EAP, a user requests connection to a WLAN through an AP, which then requests the identity of the user and transmits that identity to an authentication server such as AAA RADIUS The server asks the AP for proof of identity, which the AP gets from the user and then sends back to the server to complete the authentication Hotspot 2.0 requires the following flavors of EAP to be supported: SIM USIM Credential Type EAP Method EAP-SIM (RFC-4186) EAP-AKA (RFC-4187) X.509 certificate EAP-TLS (RFC-5216) Username/Password EAP-FAST (RFC-4851)

31 Summary Wireless devices and traffic is doubling yearly BYOD Newer Technologies and Protocols on Horizon Need to Intelligently address bandwidth and # of users Need to understand and address handheld capabilities Solving the capacity crunch requires: More radios Higher data links More efficient operation Need upgradable solution that can last 5-7 years

32 Wireless Future By 2015, 80% of newly installed wireless networks will be obsolete because of a lack of proper planning. Top Wireless Issues That May Derail Your Mobile Strategy. Paul DeBeasi, October 2011

33 The Modular Wireless Switch Modular Wireless Switch Dense radios (2 to 16 per Array) Directional, high gain antennas Distributed Intelligence 75% Less Equipment Cable pulls Switch ports
