2. White-Fi: What are the Applications ? By Akshay Sharma Research Director Communications Service Provider Technology - Gartner Feb 2012

3. Opportunities Trends in 3G/4G - WiFi Offload, Hotspot 2.0 - SIPTO, LIPA standards Can this occur for White-Fi ? White-Fi, this is a Wi-Fi like system that uses white spaces in the UHF (Ultra High Frequency) band.

4. Adoption Drivers – Newer Solutions Needed - Hotspot2.0 WiFi offload, will soon emerge as a carrier-grade offload solution White Fi ? - WISPs are looking at solutions for better in-building coverage like Femtocells, White Fi has better in-building penetration ? - Telecom Equipment vendors should build combined Femtocell with WiFi / White Fi capabilities and localized routing to save on bandwidth for shared content. - Chipset vendors like Picochip have announced converged gateway solutions integrating 802.11 b/g/n Wi-Fi with 21Mbps Release 7 HSPA+, and soon Hotspot2.0 and LTE support will occur. Newer White Fi chipsets need to occur…

5. Adoption Needs - Possibilities around utilizing White Space spectrum in a campus setting for broadband access, - Promising data rates exceeding several 100-Mbps. WISPs: - Deploy policy-based control of the network including seamless exchange of authentication certificates for both WiFi and cellular. Plan for Policy Exchange with WiFi ISPs leveraging peering relationships as needed with White Fi ISPs in the near future - Plan now for newer WiFi offloading functions in the core such as IMS VCC Applications Servers, Session Border Controllers with Mobile IP Support, and newer functions providing traffic shaping and optimal redirection to White Fi in the near future Telecom equipment vendors: - Support the ecosystem of WiFi AP functions with White Fi gear - Support combined Femtocells with WiFi / White Fi AP functions, with Data Session continuity with Mobile-IP standards.

6. Adoption Inhibitors Competition from WiFi, 4G, 3G Femtocells Interference, QoS, and capacity issues Complexity and cost to solve interference problems – Geo Location DBs Powerful TV broadcasters will continue to fight White Space – especially when Web-TV runs over it White spaces only support fixed or semi-mobile users (roaming is not yet possible). Can be mitigated via Mobile IP standards. LTE is on the horizon to allow offload from 3G to Wi-Fi networks.

7. White Fi with Ads/Billing Targeted ads, Demographics, Location-aware, Search-aware, Policy-aware, Network-aware, Session-aware, App-aware, Content-aware, Cache-aware, Context-aware

8. White-Fi Potential Applications Wide area coverage Low-power broadband Backhaul for WiFi Smart Grid, Smart Cities Cellular Offloading VoIP/Unified Communications Vehicular Communications Healthcare Communications Mesh Networks Crowd Computing ? TV Video Spectrum will kill the Cellular Radio Star ?
