The Wide Variety of Internet of Things (IoT) Technologies for Different Situations

For a very long time, Internet of Things or IoT has been promised to revolutionise the world and solve many of the issues with ARPU and Monetization that many operators are facing. Many of the predictions have yet to come pass but nevertheless, IoT is a promising technology. 

While we are now conditioned to just think about 4G & 5G for everything, IoT is a very wide topic and there are a variety of technologies that help solve some or the other issue.

While NB-IoT and LTE-M are catching on, the majority of Cellular IoT is still based on 2G / GSM.

In addition, Sigfox and LoRaWAN are also quite popular non-cellular IoT technologies.

The description says: "By 2023, there are estimated to be ~20 billion connected IoT devices. At the present time, there are already billions of devices connected to the Internet by quite, using evolving wireless technologies like Bluetooth, ZigBee, WiFi, or cellular technologies of the 2nd and 3rd generation. Due to the growing demand for connectivity, the IoT industry is developing and deploying multiple new technologies that are optimized for specific needs."

  1. Thank you for sharing such an amazing article, it was really informative. I'm sure you've heard different misconceptions about LoRaWan, and, like me, you may have believed in one of them. As a newcomer to the Internet of Things, I've discovered one of the most common myths is "LoRa is LoRaWan." While searching the internet for further knowledge, I also came across this interesting article and thought I could help you all to burst this myth too. https://bit.ly/3wlciGA

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
