OpenSignal looked at 5G speeds in isolation and also in combination with 4G use; the company also looked at the amount of time users spend connected to 4G and 5G in the 12 countries/regions studied.
Saudi Arabia, South Korea, Australia, the US, the UK, Kuwait, Germany, Switzerland, the Netherlands and Canada were included in the study as were the two regions of Hong Kong and Taiwan.
As far as the overall download speed was concerned, users in Saudi Arabia experienced 144.5Mbps, much ahead of Canada. This measure covered both 4G and 5G as it was looking at total use. Australia was seventh with 48.7Mbps.
OpenSignal's measurement of the amount of time that users spent on 4G and 5G found Australian 5G users spent only 8.6% of their time connected to a 5G service, with the balance spent connected to a 4G service.
In this category, too, called 5G availability, Saudi Arabian users were at the top, spending 34.4% of their time connected to 5G services.
Commenting on the data, which was obtained through user-initiated tests, OpenSignal's Ian Fogg said: "The US is much higher ranked on 5G availability than on average download speed because the low-band spectrum is ideally suited to enable great 5G reach and allow users to spend more time connected than in countries with higher frequency 5G spectrum.
"In the US, the low-band 5G services of T-Mobile and AT&T have helped drive a high 5G availability result. T-Mobile US’s very recent launch of standalone access 5G — where a phone no longer needs to connect to 4G in order for 5G to work — should help 5G services in future.
"Clearly, smaller geographies like Kuwait or Hong Kong have an advantage over large countries like Australia or the US in offering users high levels of 5G Availability which makes the achievements of operators in both Australia and the US — powering their 5G users’ experience ahead of the UK and Switzerland — all the more impressive."
