FIVE QUESTIONS TO BE ANSWERED (1) 1. Does average customer know what is
Broadband?
2. Does average customer understand the difference between wireless (mobile) and wire (fixed) connection to internet?
3. Does average customer expect another quality of his/her access to internet switching from wire technology to wireless?
4. 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?

5. IF ALL THE ANSWERS ARE NO ,
WHY DO WE NEED DIFFERENT
QoS MEASUREMENT PRINCIPLES,
REQUIREMENTS AND
PARAMETERS FOR WIRE AND
WIRELESS SOLUTIONS?

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.lvVisualware platform allows to measure more
parameters

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 each place • 3 GSM/UMTS (BITE, LMT, TELE2) and 1 CDMA
(Triatel) mobile internet access providers in Latvia were tested
ADDITIONAL MEASUREMENTS PROVIDED IN 2012

Regular tests are provided 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 hours a day 7 days a week
− all modems operate via Ethernet switch − measurement tool will be placed in post offices

RESULTS PROCEEDING AND PUBLISHING (1)
14
• Average results for every measurement place for every operator are calculated• All results are divided into speed groups:
< 256 kbps256 kbps – 1 Mbps1 Mbps – 2 Mbps 2 Mbps – 4 Mbps 4 Mbps – 6 Mbps 6 Mbps – 10 Mbps
> 10 Mbps
RESULTS PROCEEDING AND PUBLISHING (2)
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 the first week of April
