GSMA IoT WebTalk 'Clear Skies Ahead for Mobile-Enabled Drones'

One of the biggest challenges with UAVs and Drones is that there are no harmonized regulations allowing aerial UEs worldwide. While different countries may have different regulations, work like the LTE Aerial Profile is intended to standardize on an approach to remove concerns of interference with ground based users. When it is implemented by the MNOs, the policy will adapt to using LTE for drones. 

In Europe there are efforts from European Union Aviation Safety Agency (EASA) to enable Beyond Visual Line of Sight (BVLOS) in a safe and secure manner. The operators can help supporting in this area by, first of all, having a conversation with the national authorities and demonstrate the performances of the network. Also it is highly recommended to participate to the Aerial Connectivity Joint Activity (ACJA) work tasks to help define the right KPIs, the more mobile operators participate the better is the result.

In this GSMA IoT WebTalk (embedded below) the theme of partnership is explored as the GSMA introduces the ACJA who build communication and cooperation between the mobile and aviation industries. It contains the following:

  • Introduction
  • How to develop enablers for aviation in 3GPP standards? by Stefano Faccin, Qualcomm
  • How cellular can enable BVLOS operations? by Gerry Libunao, Verizon
  • What data can MNOs offer for BVLOS flights? by Thomas Neubauer, TEOCO
  • How to integrate cellular enabled UAS into aviation? by Boris Resnick, GLONASS Union
  • Panel and Q&A, moderated by Barbara Pareglio, GSMA

The slides are available to download here. The Q&A has been extracted and is available here.

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. The

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 Bj√∂rnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Link√∂ping 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
