At the tail-end of June, both AT&T and Swisscom announced plans to outsource their 5G mobile core networks to cloud service providers. AT&T’s announcement was with Microsoft Azure. Swisscom’s was with AWS. With the AT&T deal, Azure will be acquiring IP and engineering expertise from AT&T that it can resell to other operators. It was reported that Azure will offer jobs to current AT&T employees, as well. This move suggests Microsoft understands how critical it will be to retain talent that has deep networking knowledge. Swisscom’s deal does not appear to include AWS acquiring any Swisscom assets or employees, but the operator did say it will be using AWS for its own IT applications.
Mobile operators are racing to upgrade their networks with 5G connectivity while at the same time expanding 4G LTE coverage throughout the world. Though the latest generations of cellular technology offer faster performance and other benefits over their predecessors, they're vulnerable to some of the same security flaws. A report released Thursday by Positive Technologies explains how and why existing 4G and new 5G networks can be hurt by Denial-of-Service (DOS) attacks in particular. For its report "Security Assessment of Diameter Networks 2020," Positive Technologies simulated external attacks against 28 telecom operators in Europe, Asia, Africa, and South America during 2018 and 2019. Specifically, the company looked at 4G and 5G networks using Diameter signaling protocol, a method for coordinating data among different Internet Protocol (IP) network elements.
Everyone understands the need to track and trace and tracking was one of the first apps that kick-started the M2M industry at scale about two decades ago. It now encompasses everything from routine shipments to monitoring of high value equipment and has even further proved its worth in the pandemic, enabling tracking of essential shipments and cold chain logistics for vaccines.
With narrowband IoT (NB-IoT) now rolling out across the world, the technology is powering tracking applications for the mass-market, bringing new capabilities and functions to tracking and opening up new markets and use cases. Four essential attributes of NB-IoT, in addition to the fundamental ability of throughput, were discussed in a recent Quectel webinar
Since my last blog post warning about those who were predicting a "new paradigm" of shortage in the semiconductor industry, the media have been shouting about the "chip crisis" alongside the typical daily news diet of disaster and calamity that we have come to expect in the time of COVID. The chip shortage coverage helped create a sense of national anxiety that we were all too reliant on China for semiconductors and, in general, that semiconductor supply was dwindling. The predictable response from governments around the world was to announce plans to stimulate their respective domestic semiconductor manufacturers into expanding chip production capacity.
Fast forward a few months, and we are now finally seeing some light at the end of the chip shortage tunnel. Yet, in the wake of all the proclamations and commitments about investing in new chip capacity, we also now see manufacturers going forward with actually starting to build new plants that won't come online for another couple of years. The result, as I said in my last post: overcapacity.
