Ericsson researchers have set a new record for mmWave 5G, hitting 4.3Gbps download speeds.

mmWave is the fastest variety of 5G, and offers revolutionary speeds compared to 4G. Speeds are so fast that experts have long said it could disrupt entire industries, making things possible that could never be done with previous technology. Artificial intelligence, autonomous cars, mobile gaming, virtual and augmented reality are just a few of the industries 5G stands to have a major impact on.

Ericsson’s researchers have just displayed some of that promise, achieving a whopping 4.3Gbps downlink with mmWave 5G.

“This is a fantastic achievement,” said Per Narvinger, Head of Product Area Networks. “To put 4.3Gbps in context, that is the equivalent of downloading one hour of ultra-high-definition, or 4K, content from a streaming service in just 14 seconds. Ericsson is taking the next steps in ensuring service providers can deliver the best capacity and data rates over millimeter wave 5G. The 8CC aggregation solution we have successfully tested will enable not only higher speeds but also large-scale 5G deployments and new business opportunities.”

In the U.S., T-Mobile, Verizon and AT&T have all deployed mmWave 5G in parts of the country, although rollout is slow as a result of the frequency’s extremely short range. This has led T-Mobile and AT&T to complement their mmWave service with low-band 5G, which has far better range and coverage but offers speeds similar to 4G.

Ericsson’s announcement also lends weight to CEO Borje Ekholm’s recent comments that his company is at the forefront of 5G, both in terms of technology and scalability. In that interview, he said: “I find it’s a bit difficult to say that we’re behind when I see no one ahead of us.”

When it comes to download speeds—he’s right.
