Entertainment What is the truth about 5G? Four Corners spoke to leading experts and anti-5G activists to find out
Iraq forces free German woman kidnapped in Baghdad
A German woman kidnapped in Baghdad earlier this week was freed overnight and is now in the custody of her embassy, officials from the two countries said on Friday. German Foreign Minister Heiko Maas said he was "relieved" that Mewis was freed, confirmed she was at the embassy in Baghdad and thanked the Iraqi government for its efforts. Diplomatic sources told AFP she was in good health. - Hazy circumstances -The details of her release and the identity of her kidnappers remain hazy, with the interior ministry and Supreme Judicial Council saying they were still trying to find the perpetrators.
The global rollout of 5G has spawned wild conspiracy theories, and the coronavirus pandemic was the perfect environment for them to spread.
Four Corners has investigated these claims and examined the science around whether the technology is a threat to our health.
What do the conspiracies claim?
One theory claims 5G's millimetre wave technology is secretly being developed by governments as a weapon to threaten and control us.
ManCity lacked killer instinct
Liverpool's outstanding season was only one side of the coin on the way to the championship. It was surprising how quickly and clearly the team of Jürgen Klopp was able to hurry to the champion of the previous two years, Manchester City. © imago images Raheem Sterling also missed many chances this season. Most of the Citizens had to blame themselves.
Another conspiracy links 5G to the emergence of COVID-19, claiming coronavirus was deliberately released so 5G can be rolled out without opposition while we're all in lockdown.
The viral claims have driven believers to hold protests during the pandemic and attack 5G mobile phone towers around the world, including in Australia — despite the fact that all of these theories are demonstrably false.
Communications and Cyber Safety Minister Paul Fletcher told us that behind some of the conspiracies may be hostile governments, "who have a motive to try and create instability and disorder in democracies like Australia."
What is 5G?
5G is shorthand for the fifth generation of wireless communications technology.
The first generation was mobile voice calls, 2G brought us text messaging, 3G was about data and smartphones, 4G was optimised for video calls and moving video around. 5G will usher in a world where everything is super-fast and interconnected.
S. African anti-apartheid icon Mlangeni laid to rest
South Africa on Wednesday laid to rest anti-apartheid hero Andrew Mlangeni, who faced the death penalty alongside Nelson Mandela and others for plotting to overthrow minority white rule with guerrilla warfare. Flags flew at half mast as Mlangeni, who died last week aged 95, was laid to rest in a state funeral. "We have lost not only a great patriot, but a strident moral voice," President Cyril Ramaphosa said in his eulogy before mourners who included ministers and elite members of the ruling African National Congress (ANC).
You may have noticed that telcos like Optus, Vodafone and Telstra are already marketing 5G plans.
That will bring us data speeds 10 times that of 4G.
But the real game changer comes early next year when Australia's telcos will bid for a slice of what's called millimetre wave spectrum.
Millimetre wave is much higher frequency and promises data speeds more than 100 times faster than 4G.
For example, downloading a full-length HD movie over your wireless connection will take a few seconds rather than many minutes.
Millimetre wave technology is not only faster; there's also far less lag time — known as latency — between when a signal is sent and the device receiving the signal reacts.
Another application 5G is predicted to be particularly useful for is driverless cars.
You can imagine how latency matters with a driverless car when a sensor detects a pedestrian in front of it and the car needs to hit the brakes instantaneously — any potential delay could be catastrophic.
Zimbabwe security forces clear streets ahead of planned protests
Police and soldiers order people trying to enter the capital, Harare, to go home ahead of planned anti-gov't protests.Police and soldiers manned checkpoints and ordered hundreds of people trying to enter the city to return home. In the city centre, security agents ordered people to leave and businesses to close.
Other applications include improved artificial intelligence in robots, super-efficient agriculture and remote medicine.
Why are people scared of it?
Many people's fears about 5G stem from what's known as radiofrequency radiation.
Radiofrequency radiation is emitted at various levels from devices ranging from TVs and radios to microwave ovens, wi-fi and mobile phones.
It's been the subject of health concerns for decades.
Professor Rodney Croft is chairman of the key international body that recommends safe exposure limits for radiofrequency radiation.
He said with every new generation of technology, there's a new wave of concern from the public.
"The radiation that's being emitted by these devices is essentially the same as it's always been, and essentially the same as we've had around with radio, for instance, AM and FM radio for many years."
5G is just another form of radiofrequency radiation. But while our current 4G mobile phones emit signals that can travel long distances and easily pass through walls and other structures, 5G's millimetre waves won't travel as far.

So, for it to work there will need to be more antennas positioned closer together. In areas of high demand like a city centre, the expectation is that there could be a 5G antenna on every street corner.
Anti-5G activists claim this will expose us to a "soup" of radiation from which we can't escape.
But Professor Croft said the radiation from 5G isn't dangerous.
"This is one of the most researched physical agents in the world," he said.
"And that's what I guess gives us the confidence today to be able to say that we really do understand this very well and we know that there aren't any problems."
How did the coronavirus 5G conspiracy theory start?
The first known online appearance of the theory was tweeted on January 19 from an anonymous account that regularly posts pro-Russian government content.
That tweet linked to an article by the Russian state-owned news outlet, RT, formerly known as Russia Today.
It noted that the Chinese city where coronavirus was thought to have originated, Wuhan, also had 5G.
That tweet was barely noticed. A few days later a Belgian news outlet published an interview with a GP who suggested there might be a link between coronavirus and 5G.
The theory then kicked around online to a limited degree, but when it was picked up by notorious right-wing conspiracy website Infowars it jumped to a much larger audience.
"Benzema don't try to be like Ronaldo or Messi"
Rafael van der Vaart, who has been around Karim Benzema at Real Madrid, spoke highly of praise towards Karim Benzema. © Supplied by Football 365 Ballon d'Or: Benzema is not frustrated Rafael Van der Vaart rubbed shoulders with Karim Benzema one year at Real Madrid, during the 2009-10 season, the first of the center forward French in Spain. Like all observers, the Dutchman notes that the attacker seems at his premium, at 32 years old.
It received another massive boost when US singer Keri Hilson shared a video of a controversial US doctor making the link at an anti-vaccination conference to her millions of followers.
Other celebrities also promoted the theory, including rapper Wiz Khalifa, who tweeted about the supposed link to his 36 million followers. It was also shared by Woody Harrelson, John Cusack and singer M.I.A.
Professor Axel Bruns from Queensland University of Technology's Digital Media Research Centre told Four Corners the pandemic was the perfect environment for this type of conspiracy theory to spread.
"There's a lot of rumour going around about what the crisis is, how bad it might be, how it might affect us. Not even the government institutions and others can actually answer at that point because so much is still unknown," he said.
"Rumours end up filling that information vacuum. That's ripe ground for conspiracy theories."
Membership of Australia's largest anti-5G Facebook group surged from about 6,800 to more than 48,000 during the initial pandemic lockdown.
"People were at home and they had time to think, and they had time to ask questions that perhaps they didn't have the headspace to do before that," said Naomi Cook, who helps run the group.
Could 'hostile governments' be spreading misinformation to create division?
Australia's Communications and Cyber Safety Minister Paul Fletcher is concerned that there are bigger forces at play and that hostile countries could be deliberately spreading damaging disinformation.
Coronavirus: anti-containment activists arrested in Australia

The pandemic also continues to spread at full speed in several large emerging countries. While the coronavirus pandemic continues its course in the world , the restrictive measures (confinement, compulsory mask ...) are increasing ... and giving rise to many outcry.
"We'd be naive if we did not recognise the possibility that some of these claims are being generated by hostile governments or by others who have a motive to try and create instability and disorder in democracies like Australia," Mr Fletcher said.
"We know that disinformation and misinformation has been an issue in elections in other countries. That cannot be ruled out in my view as a possible driver of some of these."
Mr Fletcher won't name a particular country.
But among those spreading misinformation has been the US arm of Russian state-owned broadcaster RT, which has repeatedly broadcast widely discredited 5G health fears to its US audience, saying things like 5G "might kill you".
, Global Research, has published numerous articles spouting 5G conspiracy theories, some of which have reached Australia after being posted repeatedly by Australia's largest anti-5G Facebook group.
Professor Bruns said this type of misinformation campaign creates unnecessary fear.
"It creates disruptions. It creates protests. It creates possibly more people disobeying any lockdown orders, any social distancing orders," he said.
"And, of course that then further damages the economy, damages the population in the first place by spreading the virus further. So, it weakens ultimately the countries that they're addressing."
A 5G provider could potentially shut down entire countries
Globally, there's a huge amount at stake with 5G.
It not only promises to revolutionise our lives but is predicted to be a critical component of future defence and security systems.
China is emerging as a leader in 5G, especially via the global tech giant Huawei, which is selling its 5G technology to dozens of countries.
That's potentially a problem because 5G is expected to become the backbone of the "Internet of Things", where everything in a country is connected via 5G, including critical infrastructure like electricity networks, and transport, health and defence systems.
Security experts fear using Chinese-made 5G componentry could allow China to "shut down" an entire country's infrastructure during any potential future conflict.
It's what led the Federal Government in August 2018 to announce a ban on "high risk" suppliers of 5G technology, in effect banning Huawei from Australia's 5G networks.
Australia is one of a minority not using Huawei for 5G
Australia is part of a tiny minority to have banned Huawei from its 5G network, along with the UK, US and Vietnam.
Russian president Vladimir Putin has criticised the US push to ban Huawei, which is supplying 5G technology to Russia's largest telecommunications company.
Huawei said more than 40 countries have signed up to use its 5G technology in their networks.
According to Dr Huong Le Thu, a senior analyst at the Australian Strategic Policy Institute, that could be problematic for Australia's relationships in the region.
"That Huawei ban is seen in many countries as asking to choose sides. Do you want to be with team US or you want to be with team China?" she said.
"Given that Australia and a number of allies and partners in the region are trying to forge a closer security relationship and partnership, this potentially could be an issue."
