Telstra and Ericsson double LTE range

Australian operator Telstra and vendor Ericsson have announced that they have successfully managed to increase the range of an LTE cell from 100 km to 200 km. The announcement is available on Telstra exchange here and on Ericsson's website here.

No technical details are available and the range assumption would be that while the existing cells can cover up to 100 km radius, the enhancement would increase the radius up to 200 km.

Telstra blog states:

Until now, global wireless 4G standards have managed to achieve a range of only 100km from the cell. While that’s still impressive, we’re always looking to push our network capabilities further for our customers. Working with our partner Ericsson, we have deployed a solution that enables standard 4G phones to work at a distance up to 200km from the mobile base station.

We recently completed an extended call using one of our sites at Mount Dowe, east of Narrabri in New South Wales, Australia. Further testing and refinement is underway and we expect that it will become commercially available later in 2020 across select locations, further boosting network coverage as demands continue to grow.

This is a big win for our regional and remote customers. We live in a vast nation and providing 4G coverage in more places is critical in ensuring that we are providing the best coverage to our customers both in the city and the country.

This isn’t necessarily a solution for everywhere – the location of the mobile base station and the surrounding topography need to be right for the mobile device signal to get back to the base station  – but this will certainly be another deployment option in our 4G coverage toolkit when we are expanding and improving our network.

We continually work with our partners like Ericsson to provide innovative solutions to our customer needs. This achievement builds on previous mobile world firsts, including when Ericsson and Telstra again achieved another world’s first when we extended the 3G cell range to 200km in February 2007.

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.

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose Study Gro

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
