As operators have worked to upgrade 3G networks to LTE-Advanced technology, theoretical (and even real-world) peak throughput speeds have increased to where they vastly outstrip the maximum needed for any current use-case. Real-world speeds above 100 Mbps are common in certain areas, and with a 4K video stream -- barely a realistic mobile use case -- using a fifth of that, average download speed has lost some of its relevance as the overriding statistic used to measure wireless networks.
Instead, a metric of customers’ Quality of Experience provides more relevant insight into the quality of connection. With that in mind, Tutela has produced a set of five key network performance indicators that show the minimum requirements needed to flawlessly perform the most demanding mobile use-cases, including real-time HD video calling, or 1080p video streaming.
Tutela's excellent quality key performance indicators:
Download speeds of 4 Mbps or more
Upload speeds of 2 Mbps or more
Latency of 50 ms or less
Jitter of 30 ms or less
Packet loss ~0%
The mobile excellent consistent quality score measures the percentage of time that a network connection -- whether over 3G or 4G -- meets these requirements, and therefore provides the user with a flawless connection for the majority of real world use cases.
As the chart shows, all four Nordic countries perform well, with consistent quality scores over 80%. However, Norway -- which has the lowest data use per person, and the highest penetration of 4G -- has the best consistent quality of any country.
Denmark has the highest percentage of tests performed on 3G, at 16%, but has the second-best consistent quality. 85% of network connections tested in Denmark exceeded Tutela’s thresholds for excellent quality. Finland, whose population uses far more data per capita than any other country, has the lowest consistent quality score.
