Smartphone traces Café hotspot Macro cells average traffic in a medium/large size area, while a small cell covers a specific area where traffic is heavily correlated. Example is of a café in a business district, where people get their coffee and immediately fire up their browser or social network page UE RAB map over 9min period Extremely high data activity, some Smartphones are virtually always on RAB map key: HSDPA/HSUPA, Multi-‐RAB, CS, FACH, SRB Mobileusers Time
Backhaul defines small cell hotspot experience Installed in public places: cafes, malls, stores, rail stations, venues etc Multi-technology: 3G, WiFi and LTE in one box Key characteristics High quality mobile experience Small cells provide high-speed, short-range signal with low contentionBut Backhaul is the limiting factorLimited capacity, heavily loaded with 3G/4G/WiFi traffic,highly variable performance
Enter the Smart Cell Edge Cloud PLATFORM Edge Cloud APPLICATIONS Intelligent 3G/LTE small cell Cache and content Hi spec comms-‐tuned CPU Wireless Policy Mgmt. Massive storage and RAM Multi-‐mode WiFi Video adaptation SMART CELL = SMALL CELL + Hi SPEC SERVER + CLEVER APPS
Demo use case: Cache applications 1. Proactive cache First play from cloud Next plays from cache 2. Predictive cache Timed download during low Content traffic periods on backhaul from cache Cuts backhaul traffic Improves user experience
