Quality of Service Evaluation in Mobile and Broadband Networks

This presentation by Aleksandrs Čerņakovs-Neimarks, Deputy Director of Electronic Communications and Post Department at the Public Utilities Commission in Latvia, discusses the importance of understanding the difference between wireless and wire connections, the customer's expectations of quality when switching from wire to wireless, and the need for different QoS measurement principles for both technologies. The presentation also provides information on the ISPTest measurement system used to evaluate broadband networks.

  1. MOBILE/WIRELESS BROADBAND • QUALITY OF SERVICE EVALUATION, SPRK EXPERIENCE • Aleksandrs Čerņakovs-Neimarks • Deputy Director of Electronic Communications and Post Department, Public Utilities Commission, Latvia • Marciena, 29-30 August 2013

  2. Does average customer know what is Broadband? • Does average customer understand the difference between wireless (mobile) and wire (fixed) connection to internet? • Does average customer expect another quality of his/her access to internet switching from wire technology to wireless? • Do mobile operators explain to their customers that they will never have the same quality of service using wireless connection as they have using fibre? • FIVE QUESTIONS TO BE ANSWERED (1)

  3. 5. IF ALL THE ANSWERS ARE NO , WHY DO WE NEED DIFFERENT QoS MEASUREMENT PRINCIPLES, REQUIREMENTS AND PARAMETERS FOR WIRE AND WIRELESS SOLUTIONS? • FIVE QUESTIONS TO BE ANSWERED (2)

  4. Download/Upload Speed TEST Packet loss ratio Latency • PARAMETERS TO BE MEASURED Jitter

  5. ISPTEST MEASUREMENT SYSTEM EXISTS FROM 2007 • Measurement platform is based on Visualware measurement platform (www.visualware.com) • User interfaces and access tools are designed by two Latvian companies • This is a common measurement platform for both wire and wireless types of broadband • Access to measurement tool http://itest.sprk.gov.lv • Visualware platform allows to measure more parameters • MEASUREMENT PLATFORM

  6. ISPTEST CONNECTIONS

  7. REGULAR TEST • Modems available in operators service centres in current year January were used • During the year 2012 in 200 placesand during year 2013 7 months in 95 places measurements across the country were provided • 5 measurements in every mobile internet access providers network were made in eachplace • 3 GSM/UMTS (BITE, LMT, TELE2) and 1 CDMA (Triatel) mobile internet access providers in Latvia were tested • MEASUREMENTS PROVIDED

  8. TOP 20 MEASUREMENTS • Modems available in operators service centres in August were used • Measurements in 20 largest cities in 3-10 places • 3 GSM/UMTS and 1 CDMA mobile internet access providers were tested • 5 measurements to every mobile internet access providers network were made in any place • ADDITIONAL MEASUREMENTS PROVIDED IN 2012

  9. REGULAR AND TOP 20 MEASUREMENTS

  10. MEASUREMENT PLACES 2012

  11. MEASUREMENT PLACES 2013, 7 MONTHS

  12. Regular testsareprovided according to the same requirements as in 2012 • 24 hours tests will be provided in 10-15 places where: • will be measured QoS parameters values for all mobile internet access service providers 24 hoursa day 7 days a week • all modems operate via Ethernet switch • measurement tool will be placed in post offices • MEASUREMENTS PROVIDED IN 2013

  13. 24 HOURS MEASUREMENTS

  14. Average results for every measurement place for every operator are calculated • All results are divided into speed groups: • < 256 kbps • 256 kbps – 1 Mbps • 1 Mbps – 2 Mbps • 2 Mbps – 4 Mbps • 4 Mbps – 6 Mbps • 6 Mbps – 10 Mbps • > 10 Mbps • RESULTS PROCEEDING AND PUBLISHING (1)

  15. Average results for every measurement place for every operator are included in Annual QoS Report in comparable way • Measurement results divided into speed groups are included in Annual QoS Report in comparable way • Map with specified measurement places is included in Annual QoS Report • Annual QoS Report is published in SPRK website at thefirst week of April • RESULTS PROCEEDING AND PUBLISHING (2)
