  2. 3G Mobile Data: Empirical Data Measurements Les Wu August 2010

  3. 1 Test setup

  4. Test Setup • Client • Win7 netbook running Anue Profiler • Ping test to www.alcatel-lucent.com mirrored by Akamai • Wireless Devices • Cradlepoint/MiFi Device for USB data modems • Nexus 1 Phone

  5. HTC Nexus 1 Phone • Goggle Android Development Phone now discontinued • Android 2.2 (Froyo) • Quadband GSM Phone • 2 Radio Configurations for US Data Services • Native wireless and USB tethering • GPS Support • Apps: • iperf • Speedtest (from okla) • Antennas • RF Signal

  6. Protocol Generic • 1350 byte ping test to www.acatel-lucent.com (mirrored by Akamai) • 1 ping per second • 15 minute duration Mobile Tests • Drive tests taken over successive days and similar drive routes • GPS Routes captured where possible Additional Ad Hoc Data • Bandwidth tests

  7. 2 3G Fixed Wireless

  8. Geography • 1 Hong Kong Service Provider • 3 US Service Providers • www.alcatel-lucent.com served by Akamai

  9. Tale of 4 3G Service Providers (Fixed Mobile)

  10. PDV Comparison

  11. And then there’s bandwidth • Notes: • US1-3 were conducted sequentially at a single location in Everett, WA. Signal strength appeared to be good for all carriers. • The US based Akamai server appears to be in Cambridge, MA • US1-3 was conducted during the afternoon of Saturday 7 Aug. • AP1 conducted on an ad hoc basis in Hong Kong. The Akamai server was apparently located in Dingxi, China

  12. Same Location / Different Day Wed 12 Sat 7 US1 US2 US3

  13. PDV Comparisons

  14. 3 3G Mobile Characteristics

  15. Tale of 2 Service Providers Run 17a / 2.8% Run 18a / 6.6%

  16. RSSI Strength for 2 3G GSM Providers

  17. Area Drive Test • 1 256-byte ping every second to an akamai server in Boston • First 5:00 were “fixed” • RF Map from a different carrier and shows multiple drives including current trace • Packet Loss of 6.2% over 25 minutes • Notice jump in delay from 125ms -> 800ms

  18. 4 4G Requirements

  19. Longer term 4G/LTE Standardized QCI characteristics Source: 3GPP TS 23.203 v9.3.0 table 6.1.7 QCI = QoS class identifier

  20. Except … LTE Radio Access Network IP Network • Access network separated from core network with a packet gateway as a demarcation point • Radio network is VPN tunneled through the P-GW • There is additional magic in the LTE Network • Scheduling for eNodeB complex and proprietary • Healthy radio network is allegedly running at 10-2 BER with retransmission

  21. 5 Backup Data
