Mobile Broadband Performance Measuring Broadband America Measuring Broadband America • Focused on Wireline ISP performance in 2011 • Established Measurement Infrastructure consisting of – Software to administer testing • Scheduling, Software updates, measurement collection – Test nodes distributed across nation for performance testing Collaboration • Measuring Broadband America (Wired) demonstrates advantages of collaboration – Increased expertise – Identification of carrier issues – Balanced perspective – Higher integrity in final product • FCC would prefer collaborative model for MBA Wireless SamKnows • Ofcom funded client software and platform enhancements for mobile testing • Two Variants for testing – White box capability supporting multiple data dongles • Stationary or fleet placement • Multiple carriers measured simultaneously – Android software to support crowd source application • Work has been completed and is available for application in 2012 • Work based on SamKnows platform structure previously developed for wireline testing Potential Performance Information Test Duration Web browsing Est. 3 seconds Voice over IP Fixed 10 seconds at 64k Download speed 3MB fixed size Upload speed 3MB fixed size UDP latency Continuous UDP packet loss Continuous DNS resolution Est. 1 seconds Video Streaming Fixed 10 seconds at 2Mbit/s Potential Infrastructure Data • • • • • • • • Location of test Active cell tower ID and signal strength Visible neighboring cell towers (IDs/RSSI) Active network operator ID SIM network operator/ID Bearer Channel (CDMA, GPRS, EDGE, etc) Roaming state (True/False) Other usage data of potential interest Measurement Controls • Volunteers required for test – 90,000 solicitations received for terrestrial trials – Carrier participation provides more efficient means for solicitation • Platform allows control over – Nature of tests – Scheduling of tests – Measurement points included in testing infrastructure • We can control impact of tests • Carrier participation could – Lessen impact on consumer (no data billing) – Allow more use of white boxes (data port contribution) Assessment • Through a combination of work implemented in MBA program and interest in other regulatory jurisdictions opportunity exists to undertake mobile measurement study – We have opportunity to evaluate this approach against more traditional metrics • Infrastructure data describing tower/service coverage is available – Potential benefit to other efforts • This type of data is increasingly collected but eclectically – E.g. OOKLA, but tests contain consumer bias – By Content providers: e.g. Google, but kept confidential – In short “it’s out there” but we can obtain in a more public and statistically valid method • Two regulatory jurisdictions pursuing similar paths – England/Brazil – Others likely to follow Benefits • Short Term – First statistically valid study of cellular performance of major and other service providers – Independent view of cellular coverage • Long term – Move towards common standard for measuring performance Preferred Structure • Potential exists to go forward without active cooperation of carriers • Preference to extend MBA model to wireless carriers – Industry input into approach and greater acceptance of results Immediate Steps • Contract issues force quick start – Need to announce start of program July/August • Need determination on how to proceed – Collaborative/Independent model • If Collaborative model – Engage service providers on testing of software – Establish planning structure
