Service Provider WiFi Presented by: Daniel Person Coyote Solutions Group www.coyotesolutions.com July 24th, 2012 ©Coyote Solutions Group 2012. All rights reserved. 3 What Questions 1. What is the most cost effective manner to handle this traffic? 2. What are the key requirements to handle this traffic? 3. What do we need to take into account in order to maintain a consistent Quality of Experience for the subscribers? ©Coyote Solutions Group 2012. All rights reserved.

Clean air provides unique insight into RF Domain • No single entity responsible for SP WiFi architecture definition 3GPP has defined an architecture for “trusted non-3GPP” – baseline for target architecture • Challenging to deliver seamless experience PMIPv6 based architecture for seamless mobility across WiFi. IP Persistence can be delivered across inter-technology access • Current Bring Your Own (BYO) WiFi approach devalues SP to bit-pipe provider Ability to integrate Consumer CPE into architecture • Diverse range of client requirements Able to leverage client functionality whenever available Source: Cisco, 2012. ©Coyote Solutions Group 2012.
