In the US, Samsung’s Galaxy S20+ and Galaxy S20 Ultra, launched in March, both support millimetre-wave frequencies. But telcos AT&T, Verizon and T-Mobile had rolled out the network even before the millimetre wave 5G-capable smartphones were released. Meanwhile, individual customers and businesses in Australia are still limited to 5G in the sub‑6 GHz range.
The higher-frequency 5G technology is currently only available in the US, but has also been assigned in Italy and Finland. Several other countries are planning to upgrade soon, including Singapore, Japan, Taiwan and South Korea. Local licenses are also available in the UK.
According to a European Commission report, 15 of the European Union member states, as well as the UK, have already completed at least one 26GHz spectrum auction. And at least one spectrum auction was scheduled for this year for 25 countries, as well as the UK.
On the other hand, the Australian government is planning to auction off the use of the 26GHz frequencies in March next year, for the first time ever.
This leaves us trailing behind. The longer the delays in bringing the millimetre wave spectrum to Australia, the longer we’ll have to wait before benefiting from it.

Sold to the highest bidder
Following next year’s scheduled auction, Australians may not be able to experience any 5G millimetre wave connectivity until late 2021, or even early 2022.
The result will depend on the best business cases put forth by mobile companies during the auction, as well as how they allocate the bandwidth between individuals and business customers. The spectrum will likely be prioritised for industrial use first, before it’s rolled out to residential customers.
That said, if businesses such as manufacturers, sports stadiums, shopping malls, offices and high-rise residential buildings benefit, then individual customers are likely to benefit as well. This is because costs would likely drop and prices would follow.
This was the strategy followed in the US and which Optus has indicated it’s also likely to follow.
What speed tests in Australia reveal
During isolated tests in Australia, non-millimetre wave 5G speeds were recorded to be at least 3.9 to 4.6 times faster than 4G, for Optus and Telstra. But this is still slower than the 1Gbps speeds usually associated with 5G.
According to a Telstra report from last month, millimetre-wave tests conducted by the company promised speeds of 4.2Gbps. While this was for a data call, as opposed to wifi access, these results are positive and on par with what Apple is promising for new iPhone 12 users in the US (but not yet the UK).
Telstra claims it already has live mobile sites that can support millimetre-wave frequencies on its network, ready for deployment. It says it has spent the past 18 months laying the foundations for a millimetre-wave 5G network to come into use once the frequencies become available.
