Boasting about validation of the industry’s first 5G carrier aggregation on 700 MHz and 4.9 GHz might not be the biggest humblebrag but remember who has access to this spectrum.
Most looking at this statement might find it slightly unusual. The 4.9 GHz spectrum is a band few around the world are looking at now or even considering in the foreseeable future. The US is, but that is of little use to state-owned vendor ZTE, but so are a few Chinese telcos.
Looking at the number of base stations which will be needed in China to ensure 5G works as intended, the estimates vary quite considerably. However, they are in the millions, an absurd amount of business should you be lucky enough to be selected as one of the vendors.
With this trial, perhaps ZTE has cast its gaze towards securing additional contracts with China Mobile and China Broadcasting Network, both of whom are trialling 5G in the 4.9 GHz spectrum band.
What ZTE is claiming today is to have validated 5G carrier aggregation on 700 MHz and 4.9 GHz spectrum bands. The team also happens to offer a 700 MHz + 4.9 GHz dual-band networking solution, to allow telcos to make better use of the 700 MHz spectrum licences for 5G connectivity.
In March, the Ministry of Industry and Information Technology (MIIT) approved the release and refarming of certain spectrum bands.
As it stands, only China Broadcast Network has access to the 700 MHz band, though it is in discussions with China Mobile regarding co-construction. China Mobile is also operating around the 4.9 GHz spectrum bands, so will be very interested in the trials being conducted by China Broadcast Network.
Alone, these two spectrum bands aren’t the greatest foundation for a China Broadcast Network assault on the 5G market. 4.9 GHz doesn’t offer the coverage and 700 MHz lacks the download speeds. But a carrier aggregation solution to marry the two is an interesting proposition.
Samsung Electronics says it managed to hit 8.5 Gbps over 5G in a lab, using 800 MHz of millimetre-wave spectrum over a couple of devices.
Using one Samsung 5G access unit, Samsung beamed a fat pipe of data to two test devices, then added up the total data rates to get to the 8.5 Gbps total. The key underlying technologies were carrier aggregation and MU-MIMO (Multi-User, Multiple-Input, Multiple-Output). Samsung is heralding this as an illustration of how great 5G over mmWave is, but let’s see them replicate those kinds of data rates in the wild.
“Samsung will continue to be at the forefront in advancing 5G mmWave technology,” said Hyunho Park, SVP of the Networks Business at Samsung Electronics. “This successful demonstration proves mmWave’s potential to deliver new kinds of business use cases and open up opportunities for mobile operators. We look forward to building on this significant technical breakthrough to fuel our continuous journey towards an innovative and vibrant mmWave ecosystem.”
There’s not a lot else to say about the landmark, other than what it says about Samsung’s competitiveness in the 5G networks space. With Huawei coming under increasing pressure in these fractious times, there will be plenty of opportunities for Samsung to increase its share of the networking market. Here’s a vid to prove it’s legit.
Huawei decided it was time to break some records so it set up a test network that seems to have been designed solely to do that.
The project was undertaken in Istanbul, in partnership with Türk Telekom. The specific record claimed is single-user 5G speed – i.e. to a single device. The two of them managed to hit 2.92 Gbps, which they claim is faster than the previous record-holder, although they don’t how much by.
“We combined two 5G carriers and established a new world record by reaching speeds of above 2.92 Gbps in our live 5G test network,” said Yusuf Kıraç, Türk Telekom’s CTO. “We are also the first operator to experiment with the 5G New Radio Carrier Aggregation Technology (C-Band NR Carrier Aggregation), which doubles the 5G link speed. Türk Telekom will continue to lead the development of all new generation technologies that our country needs in the future, as we do today.”
“In today’s test, what we have achieved is not only a record in Turkey but also a world record for 5G speed,” said Simon Pei, Deputy Country General Manager of Huawei Turkey. “Based on C-band 200MHz IBW and 2CC Carrier Aggregation technologies which only Huawei products can support, the test was performed in Türk Telekom’s test network with Huawei 5G commercial network equipment.”
Huawei seems to be on one of its European charm offensives this week. It also issued a press release about a study into how important Huawei is for the European economy, another about some EMEA certification that it thinks is a big deal and one more about its attendance at the Web Summit in Lisbon. On top of that the Huawei Chairman is going to live stream another of his chats tomorrow, which will presumably feature plenty of talk about how much better off Europe is with Huawei involved.
