It also offers better value for money (kbps per US dollar) when compared to similar offerings by SLT, the dominant fixed line operator, and its Mobitel mobile phone subsidiary.
In its latest QoSE report, LIRNEasia compared download speeds of three similar broadband packages in Sri Lanka.
These were Dialog's post-paid broadband (1Mbps), Mobitel’s Zoom890 (1Mbps) and SLT’s Office (2 Mbps).
The underlying technologies of the different packages would most certainly impact their performance, said Shazna Zuhyle, research manager at LIRNEasia.
But the focus of LIRNEasia’s broadband QoSE benchmarking was on the comparison between what is promised or advertised versus the actual speeds delivered by the operators and how they measure up on other measurements.
These include round trip time (RTT), or the time delays in data transfer, as well as jitter, the variation in time between the arrival of data packets, and packet loss thresholds.
"In this light, the Dialog broadband package performed above expectations, while both SLT and Mobitel, below the advertised speeds," the LIRNEasia statement said.
"However, on other measures SLT performed considerably better than the Mobitel and Dialog packages on Round Trip Time as well as jitter."
The QoSE methodology compared upload and download speeds of data transfer to different server locations, within the Internet Service Provider, within Sri Lanka and internationally, as well as other important indicators of quality.
LIRNEasia said the tests were done at six time intervals on two weekdays in eleven locations across seven countries in South and Southeast Asia.
Rather than comparing download speeds between packages in different locations, LIRNEasia analyzes package speed compared to what was promised by the operator, as well as the "value for money" or Kbps per US dollar.
"LIRNEasia’s QoSE methodology offers much needed independent information for consumers to make informed decisions on broadband packages," said Zuhyle."The (telecom regulator) should promote such transparency in order to boost competition in the broadband market and improve service quality."
