Cellular Connectivity Technology Landscape and Standards for Industrial IoT

We have covered tutorials on IoT, IIoT and even Industry 4.0 as part of 3G4G. Recently, Cambridge Wireless (CW), the well known international community for companies involved in the research, development and application of wireless and mobile, internet, semiconductor and software technologies relaunched their Industrial IoT SIG. As part of the relaunch, a refresher webinar was held to explain the concept of Industrial IoT. All the sessions as well as the Q&A session were fantastic. You can view the resources here once shared. For this blog post, we are looking at the final talk by Sylvia Lu, FRSA, Head of Technology Strategy, u-blox UK, Member of Advisory Board, UK5G. Let's start with some example use cases on the factory floor that you can see shown in the picture above. Some of the topics that are shown in the picture has been covered as part of other blog posts and are listed at the bottom of this post. This slide nicely summarizes not only the cellular and 5G standards but

Next-generation Wireless LANs in the IEEE 802.11 Working Group

NTT Technical Review Vol. 19, No. 2, Feb. 2021 provided a fantastic summary of Standardization of Next-generation Wireless LANs in the IEEE 802.11 Working Group. Here is an extract from the article : Institute of Electrical and Electronics Engineers (IEEE) 802.11 is a working group (WG) within the IEEE 802 LAN/MAN Standards Committee that helps develop standards related to local area networks (LANs) and metropolitan area networks (MANs). It is responsible for standardization of physical layer and medium access control (MAC) layer technologies of wireless LANs. There are several types of subgroups within the IEEE 802.11 WG. A task group (TG) is a subgroup responsible for developing a technical standard or recommended practice. A study group is a preparatory group to create a TG to discuss use cases, technologies, and feasibilities. As a result of discussion, a study group creates documents called Project Authorization Request and Criteria for Standards Development. There are also a grou

Delivering Next-Generation Connectivity with Evolved Wireless Backhaul

As we have already started talking about the post-5G world, we need to keep in mind that 5G still has a lot of enhancements and new features in pipeline. Many of these new features will require support of an enhanced backhaul, be it terrestrial or in the sky.  Earlier this year, GSMA released a report on backhaul, titled, "Wireless Backhaul Evolution: Delivering next-generation connectivity" that outlines the evolution of this important area. It has been written by ABI Research and details wireless backhaul for 5G era and the role played by new backhaul and existing bands, as well as technologies that improve spectrum efficiency. The summary of the report says: The transition to 5G will need a sizable backhaul evolution to accommodate growing traffic and new network capabilities. Despite the growing importance of fibre, wireless backhaul is set to play a central role in these developments. This means regulators have a vital role as their decisions moving forward will impactfu
