Some of the biggest hurdles in reaching 6G communications – more data sent much faster on unrestricted bandwidth – could have been unlocked by a team of scientists in Australia.
They say they have developed a polarisation multiplexer that significantly improves current availability that could be key to realising the ambitions of 6G mobile tech.
The multiplexer makes it possible for several input signals to share one device or resource – such as the data of several phone calls being carried on a single wire.
6G – the next generation of wireless communication – expands on the infrastructure of 5G but will also be designed to surpass it.
6G aims to operate at one terabyte – 1,000 gigabytes of data at one microsecond, while 5G delivers 20 gigabytes at 1,000 microseconds.
The scientists from The University of Adelaide, whose work is published in the journal Laser & Photonic Reviews, say their work brings 6G communications much closer.
“Our proposed polarisation multiplexer will allow multiple data streams to be transmitted simultaneously over the same frequency band, effectively doubling the data capacity,” said Prof Withawat Withayachumnankul from Adelaide’s School of Electrical Engineering.
“This large relative bandwidth is a record for any integrated multiplexers found in any frequency range.”
The terahertz frequencies – which can support unprecedented bandwidth – allow ultra-fast wireless communication and data transfer, but there have been problems in effectively managing and utilising the spectrum.
The Adelaide multiplexer could help answer those issues.
The new device effectively doubles communication capacity under the same bandwidth with lower data loss than existing devices.
“This innovation not only enhances the efficiency of terahertz communication systems but also paves the way for more robust and reliable high-speed wireless networks,” said Dr Weijie Gao, a postdoctoral researcher collaborating with Prof Masayuki Fujita at Osaka University.
“As a result, the polarisation multiplexer is a key enabler in realising the full potential of terahertz communications, driving forward advancements in various fields such as high-definition video streaming, augmented reality and next-generation mobile networks.”
The work significantly advances the practicality of terahertz technologies.
“By overcoming key technical barriers, this innovation is poised to catalyse a surge of interest and research activity in the field,” said Prof Fujita, who is a co-author of the paper.
“We anticipate that within the next one to two years, researchers will begin to explore new applications and refine the technology.”

Who was Alfred Nobel?
The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.
- In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
- Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
- Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.

How to invest in gold
Investors can tap into the gold price by purchasing physical jewellery, coins and even gold bars, but these need to be stored safely and possibly insured.
A cheaper and more straightforward way to benefit from gold price growth is to buy an exchange-traded fund (ETF).
Most advisers suggest sticking to “physical” ETFs. These hold actual gold bullion, bars and coins in a vault on investors’ behalf. Others do not hold gold but use derivatives to track the price instead, adding an extra layer of risk. The two biggest physical gold ETFs are SPDR Gold Trust and iShares Gold Trust.
Another way to invest in gold’s success is to buy gold mining stocks, but Mr Gravier says this brings added risks and can be more volatile. “They have a serious downside potential should the price consolidate.”
Mr Kyprianou says gold and gold miners are two different asset classes. “One is a commodity and the other is a company stock, which means they behave differently.”
Mining companies are a business, susceptible to other market forces, such as worker availability, health and safety, strikes, debt levels, and so on. “These have nothing to do with gold at all. It means that some companies will survive, others won’t.”
By contrast, when gold is mined, it just sits in a vault. “It doesn’t even rust, which means it retains its value,” Mr Kyprianou says.
You may already have exposure to gold miners in your portfolio, say, through an international ETF or actively managed mutual fund.
You could spread this risk with an actively managed fund that invests in a spread of gold miners, with the best known being BlackRock Gold & General. It is up an incredible 55 per cent over the past year, and 240 per cent over five years. As always, past performance is no guide to the future.

How Tesla’s price correction has hit fund managers
Investing in disruptive technology can be a bumpy ride, as investors in Tesla were reminded on Friday, when its stock dropped 7.5 per cent in early trading to $575.
It recovered slightly but still ended the week 15 per cent lower and is down a third from its all-time high of $883 on January 26. The electric car maker’s market cap fell from $834 billion to about $567bn in that time, a drop of an astonishing $267bn, and a blow for those who bought Tesla stock late.
The collapse also hit fund managers that have gone big on Tesla, notably the UK-based Scottish Mortgage Investment Trust and Cathie Wood’s ARK Innovation ETF.
Tesla is the top holding in both funds, making up a hefty 10 per cent of total assets under management. Both funds have fallen by a quarter in the past month.
Matt Weller, global head of market research at GAIN Capital, recently warned that Tesla founder Elon Musk had “flown a bit too close to the sun”, after getting carried away by investing $1.5bn of the company’s money in Bitcoin.
He also predicted Tesla’s sales could struggle as traditional auto manufacturers ramp up electric car production, destroying its first mover advantage.
AJ Bell’s Russ Mould warns that many investors buy tech stocks when earnings forecasts are rising, almost regardless of valuation. “When it works, it really works. But when it goes wrong, elevated valuations leave little or no downside protection.”
A Tesla correction was probably baked in after last year’s astonishing share price surge, and many investors will see this as an opportunity to load up at a reduced price.
Dramatic swings are to be expected when investing in disruptive technology, as Ms Wood at ARK makes clear.
Every week, she sends subscribers a commentary listing “stocks in our strategies that have appreciated or dropped more than 15 per cent in a day” during the week.
Her latest commentary, issued on Friday, showed seven stocks displaying extreme volatility, led by ExOne, a leader in binder jetting 3D printing technology. It jumped 24 per cent, boosted by news that fellow 3D printing specialist Stratasys had beaten fourth-quarter revenues and earnings expectations, seen as good news for the sector.
By contrast, computational drug and material discovery company Schrödinger fell 27 per cent after quarterly and full-year results showed its core software sales and drug development pipeline slowing.
Despite that setback, Ms Wood remains positive, arguing that its “medicinal chemistry platform offers a powerful and unique view into chemical space”.
In her weekly video view, she remains bullish, stating that: “We are on the right side of change, and disruptive innovation is going to deliver exponential growth trajectories for many of our companies, in fact, most of them.”
Ms Wood remains committed to Tesla as she expects global electric car sales to compound at an average annual rate of 82 per cent for the next five years.
She said these are so “enormous that some people find them unbelievable”, and argues that this scepticism, especially among institutional investors, “festers” and creates a great opportunity for ARK.
Only you can decide whether you are a believer or a festering sceptic. If it’s the former, then buckle up.
