Around the world, 5G speed records continue to fall, as telecommunications firms compete to outdo one another in the race to unlock the technology’s potential.

The predictions around 5G’s potential to offer blindingly fast connections and download speeds in the realm of 10 to 30 times faster than current 4G LTE connections have circulated for years. 

So far, however, most customers who have access to 5G services have only experienced marginal jumps in speed compared to the kind of connectivity offered by strong 4G connections. 

In the US (a particularly dire example) average 5G network download speeds hover at around 70Mbps. AT&T is the fastest at 75.6Mbps and Verizon is the slowest with 67.1Mbps, which is probably why the US mobile network operator (MNO) bid almost double the money put forward by its closest competitor (AT&T) at the latest 5G spectrum auction. 

Those kinds of speeds are hardly the generation leap that customers and enterprises have been promised, and while the US’ 5G speeds are far lower on average than other strong adopters like South Korea - which comfortably embarrasses the US with average download speeds in excess of 351Mbps - and Saudi Arabia, it’s still an issue that, for a large number of new 5G users, the technology isn’t delivering the kinds of speeds that operators have promised. 

Nevertheless, the speeds being achieved under test conditions on commercial devices are continuing to get faster. 

On Wednesday, South Korean electronics giant Samsung announced that its engineers have officially broken a new world speed record for 5G. 

By combining 4G LTE and high-band mmWave 5G, technicians at Samsung’s Korean test lab achieved data speeds of 5.23Gbps on a Samsung Galaxy S20+. The test was carried out using 40MHz of 4G frequency and 800MHz of 5G frequency in the mmWave band. 

Using 4G to support the low-end spectrum needs of such a connection is relatively unique, and points towards a future where 4G and 5G assets can work in tandem to better support users across a finite amount of available spectrum. 

“Mobile operators need to make the most of their finite spectrum assets in order to ensure user experiences that deliver the full value of 5G,” remarked Ed Gubbins, Principal Analyst at GlobalData. “This achievement showcases Samsung’s distinguishing ability to leverage an end-to-end portfolio and broad expertise that spans core, RAN and devices to help operators maximize the return on their 5G investments.”

The recorded speed breaks the previous record of 5Gbps, which was set back in December of last year by Telstra, Ericsson and Qualcomm

It’s worth noting that these aren’t the fastest speeds we’ve seen over a 5G network. On December 7, 2020, Etisalat recorded speeds of 9.1Gbps on its own 5G network, but used a prototype device built for the task, rather than a smartphone that customers can buy on the market.

“Through this demonstration, Samsung is proud to achieve another breakthrough record in 5G data speeds, now spotlighting the power of using a dual 4G and 5G approach, delivered directly to a single user,” said Ji-Yun Seol, Vice President, and Head of Air Technology Group, Networks Business at Samsung. “This reinforces our commitment to delivering the best possible 5G solutions to our customers and our ongoing support to help mobile operators accelerate the benefits of 5G services to their users.”

EDGEMATRIX and NTT DOCOMO deliver AI at the edge

Leading Japanese telecommunications firm NTT DOCOMO, together with startup EDGEMATRIX, is harnessing the power of 5G to support artificial intelligence-enabled video, real-time analytics and, ultimately, the next step in the evolution of the modern smart city. 

Founded under the roof of Silicon Valley tech firm Cloudian, EDGEMATRIX has grown into a cutting edge startup based in Japan. NTT DOCOMO has been a shareholder in the company since 2019, having spent the past two years jointly developing and commercialising EDGEMATRIX's revolutionary edge-AI platform using high-speed, high-capacity, low-latency 5G technology. NTT DOCOMO, together with EDGEMATRIX, launched a world-first edge AI platform for intelligent video analytics, enabling high resolution, high security, and real-time video using AI.

The platform simplifies, manages and oversees the implementation and integration of AI at the edge, which captures, analyses and stores video close to where it is captured in industrial and retail settings, "on location at factories, buildings and other outdoor and indoor locations." The solution is also used in social infrastructure such as roads, railroads, and long-term care facilities for safety monitoring and anomaly detection.

Using Edge AI Box, a compact indoor and outdoor device equipped with a GPU for deep learning-based AI and a communication module (WiFi/LTE/5G) together with various interfaces such as camera connection, it becomes possible to process video streaming from surveillance cameras on-site (at the edge) and in real-time. EDGEMATRIX's Edge AI Boxes can be installed across a site and then monitored using the company's platform. The platform maps the locations of multiple Edge AI Box devices installed on site, monitors their operational status and enables the devices to be controlled remotely. 

EDGEMATRIX's customers can use the platform to pruchase additional AI applications from a rapidly-expanding ecosystem which allow them to implement the right solution for the right situation. This simplifies the implementation and upgrade of edge AI for processing and storing video data captured with video cameras at customer premises either outdoor or indoor. Using "Edge View" feature, it is also possible to simultaneously display on the browser a large number of AI-processed real-time videos from the field.

Partnerships like this are key to NTT DOCOMO’s efforts to integrate 5G technologies into the modern enterprise. 

Zaif Siddiqi, Executive Director and Global Head of NTT DOCOMO’s 5G & IoT Business Department, comments: “When you're approaching digital transformation, there's more to it than just leveraging cutting edge technologies into new customer experiences.” Unless the needs of the customer, and the underlying market forces at play, can be truly understood, “5G doesn’t mean anything,” he explains, adding that in order to find the right contexts for deployment, “Selection of the right partners is extremely important to delivering on the potential value of 5G.”
