Beyond Hyper-Connectivity


Dr. Dong-Seung Kwon, ETRI spoke at the 1st 6G Wireless Summit in Oulu back in March. His talk was focussed on beyond hyper-connectivity.

According to PCMag:

In general, hyperconnected refers to the high-tech communications of the 21st century delivered primarily by the Internet, all of which is 24/7 and never ceases. It encompasses radio, TV, phone and video calls, texting, email, blogs, forums, chat rooms, instant messaging and social media, as well as access to corporate data. The smartphone has been a major catalyst, connecting more people to more things than any other electronic device.

The following is the summary of Dr. Dong-Seung talk:

We are now moving toward hyper-connected world by 5G mobile technology, which is to extend the market to vertical market and the true personalized service keeping privacy. While recently we have experienced the various intelligent services based on massive big data coming from the current 4G technology, I would like to mention the several technical future ways to enable intelligent digital transformation, such as unlimited connectivity, trustworthy networking, network intelligence.


The slides are available here. The following is interesting regarding 6G research and directions from IEEE magazine

CSI-RS vs SRS Beamforming

In an issue of Signals Flash by Signals Research Group (SRG), they talked about 2 different types of MIMO. Quoting from their journal, "CSI-RS versus SRS. Those operators that have tested or made token use of MU-MIMO leverage a flavor of MU-MIMO that is based on CSI-RS. The MU-MIMO network we tested was based on SRS, which makes it far more likely to observe sixteen spatial layers (versus eight)." I reached out to Emil Björnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Linköping University to see if he has explained this in any of his videos. Here is what he said: " I'm not talking about 3GPP terminology in any of my videos. But you can listen to the slides that starts around 12:40 in this video (embedded below) . If you are looking for CSI-RS vs SRS based MU-MIMO, then jump to around 12:40 in this video where you can see CSI-RS being referred to as "grid of beams" and SRS is similar to the other option, which is t

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation.
