The Project Coordination Group (PCG) of 3GPP recently approved a new logo for use on specifications for 6G, during their 52nd PCG meeting, hosted by ATIS in Reston, Virginia. As with previous logos, surely people in general will use them not just for 3GPP 6G compliant products, but for all kinds of things.
Over the years many people have reached out to me to ask for 3GPP logos, even though they are available publicly. All 3GPP logos, from 3G to 6G is available in the Marcoms directory here. In addition to the logo, each directory also lists guidance for use of the logos. For example, 3GPP does not allow the use of the logo as shown on the left in the image on top of the post while the one on the right is okay.
Surely there isn't an issue for general use but for anyone wishing to use the logos for their products, equipment, documentation or books, they will have to strictly comply with the rules.
I am fascinated by and have previously written blog posts about transparent antennas. Back in 2019 NTT Docomo announced that they have been working with glass manufacturer AGC to create a new transparent antenna that can work with a base station to become an antenna. Then in 2021, NTT Docomo and AGC announced that they have developed a prototype technology that efficiently guides 28-GHz 5G radio signals received from outdoors to specific locations indoors using a film-like metasurface lens that attaches to window surfaces. Transparent antennas/lens are one of the pillars of Docomo’s 6G vision as can be seen here.
I succeeded in my quest to find a wow product finally at #MWC24. Wavethru by AGC is an amazing solution for densification by providing coverage inside-out. Lookout for a post on the Telecoms Infrastructure blog in a few weeks time #3G4G5Gpic.twitter.com/RmuD1NQ7nS
Every year at Mobile World Congress I look for a wow product/demo. While there were some that impressed me, the suite of products from Wave by AGC (WAVEANTENNA, WAVETHRU and WAVETRAP) blew me away. Let’s look at each of them briefly:
WAVEANTENNA is the transparent glass antenna which is generally installed indoors, on a window or a glass pane. It can be used to receive signals from outdoors (as in case of FWA) or can be used to broadcast signal outdoors (for densification based on inside-out coverage). In the newer buildings that has thermal insulation films on the glass, the radio signals are highly attenuated in either direction, so this solution could work well in that scenario in conjunction with WAVETHRU.
The WAVETHRU process applies a unique laser pattern to the glazing with 30 µm laser engraved lines that are nearly invisible to the naked eye. Treatment is so gentle, it does not affect the physical properties of the glazing, which remain the same. This radio-friendly laser treatment improves the indoor radio signal by around 25 dB, to achieve almost the same level of performance as the street signal. Just 20% to 30% of the window and floors 0 to 4 need to be treated to improve the indoor signal on all frequency ranges under 6GHz.
In case of coverage densification by providing inside-out radio signals, WAVETRAP can be used for EM wave shielding by stopping back-lobes within the building.
This video from WAVE by AGC explains the whole densification solution:
Now the question is, why was I impressed with this solution? Regular readers of this and the Telecoms Infrastructure Blog will have noticed the various solutions I have been writing about for mobile network densification in downtown areas and historic cities with listed buildings where limited space for infrastructure deployment presents several challenges.
In brief, we can categorise these challenges as follows:
Physical Space Constraints like lack of space or strict regulations as in case of listed buildings and heritage sites.
Aesthetics and Visual Impact could be an important consideration in certain historic city centres. Deploying large antennae or towers can clash with the architectural character and heritage of the area and may require concealing antennae within existing structures like chimneys, bus shelters, phone boxes & lampposts, or using disguised designs like fake trees to minimize visual impact.
Technical Challenges can arise in dense urban environments due to interference from neighbouring cells, unreliable backhaul connectivity, interruptions in the power supply due to siphoning, etc.
Community Engagement and Perception is another important area to consider. There is no shortage of NIMBY (Not in my back yard) activists that may oppose new infrastructure due to health concerns, aesthetics, or fear of property devaluation. Engaging with the community, providing accurate information about EMF exposure, and addressing misconceptions are crucial.
Regulatory and Permitting Hurdles that may arise due to many cities and councils imposing zoning and permits requirements. Obtaining permits for infrastructure deployment involves navigating local regulations, zoning laws, and historic preservation boards. There may also be height restrictions that may hinder optimal antenna placement.
Finally, Cost and ROI are important consideration factors as all of the above increases the costs as well as the time required. Customized designs, site acquisition, and compliance with regulations are one of the major factors that not only increase costs but also delays infrastructure rollouts. Operators often weigh the benefits of improved coverage and capacity against all the expenses and headaches of infrastructure deployment and then decide on what to deploy and where.
A solution like WAVEANTENNA in conjunction with WAVETHRU and WAVETRAP can significantly reduce the hurdles and improve coverage significantly.
While I have talked about the solution in general, it can also be applied indoors to Wi-Fi, in addition to 4G/5G. This may be useful in case of Enterprise Networks where appearance is of importance and probably not of much use in case of warehouses or Industrial/Factory Networks.
It's been a while since we covered V2X as a topic on this blog. If you are not well versed with CAVs and V2X, we recommend you to watch our tutorials on the 3G4G page here.
The networking channel hosted a seminar on 'Vehicular networking' last month. Quoting from the webinar preview:
Looking back at the last decade, one can observe enormous progress in the domain of vehicular networking. Many ongoing activities focus on the design of cooperative perception, distributed computing, and novel safety solutions. Many projects have been initiated to validate the theoretic work in field tests and protocols are being standardized. We are now entering an era that might change the game in road traffic management. Many car makers already supply their recent brands with cellular and Wi-Fi modems, also adding C-V2X and ITS-G5 technologies. We now intend to shift the focus from basic networking principles to open challenges in cooperative computing support and even on how to integrate so-called vulnerable road users into the picture. Edge computing is currently becoming one of the core building blocks of cellular networks, including 5G, and it is necessary to study how to integrate ICT components of moving systems. The panellists will discuss from an industrial perspective the main research challenges for the advancement of vehicular networking and the novelties that we can expect to see coming in the short term. Panellists with extensive experience in Internet measurements, networks related to sustainable development goals, and highly-localized earth observation networks will discuss these topics and participate in a Q&A session with the audience.
The presentations were not shared but the video of the panel discussion is as follows:

Peter Rysavy is the president of Rysavy Research LLC, the consulting firm that he has led since 1993, focusing on computer networking, wireless technology, and mobile computing. Recently he did a presentation for Oregon Chapter of IEEE Communications Society (ComSoc). The abstract of the talk states:
Wireless communication is fundamental to our digital society, with radio spectrum the key enabling resource. Understanding the critical role of spectrum provides deep insight into how wireless technologies function and how they will evolve. This enlightening talk delves into the ingenious advancements in Wi-Fi and cellular networks to harness spectrum, including increasing efficiency, deploying new bands, aggregating channels, and dynamically sharing spectrum. Despite huge progress, formidable challenges remain in meeting soaring demands for capacity, achieving global harmonization, and ensuring coexistence with existing services.
Key takeaways:
There is increasing demand for wireless spectrum from technologies like WiFi and 5G cellular networks, but the amount of usable spectrum is finite.
Different spectrum bands have tradeoffs between coverage, capacity, and ability to support new technologies. The mid-band spectrum between 2 and 6 GHz is well-suited for 5G.
Technologies are evolving to use spectrum more efficiently through techniques like carrier aggregation, advanced modulation, massive MIMO, and puncturing in WiFi 7.
The US lacks a clear long-term national spectrum strategy and roadmap, putting it at a disadvantage compared to countries like China, which plan spectrum allocations years in advance.
Spectrum sharing is complex with no one-size-fits-all solution, though approaches like beamforming, dynamic spectrum access databases, and sensing show promise if challenges are addressed.
Harmonizing spectrum use globally through conferences helps drive economies of scale in devices and supports roaming, though the US diverges in some bands like 6 GHz assigned solely to WiFi.
Critical infrastructure requires precise timing to operate. This reliance makes the infrastructure vulnerable to disruptions in timing that can be either intentional or unintentional. Intentional disruptions can be caused by GNSS jamming or spoofing or network attacks.. Unintentional disruptions are usually caused by equipment failures or acts of nature.
Back in April 2022, Alliance for Telecommunications Industry Solutions (ATIS) hosted a webinar on this topic, a precursor to the Annual Workshop on Synchronization and Timing Systems (WSTS). The webinar featured top industry experts delivering insight into the latest techniques for adding resilience and robustness to timing infrastructure. It covered the most critical topics in timing resilience, including:
Redundancy
Holdover
Management
Monitoring
Alternative reference time sources
Examples address networks used for critical industry applications such as:
Power grids
Telecommunications
Finance systems
Broadcast/media

Experts participating in the webinar and their presentations are as follows:
I have been asked about the UE Assistance Information (UAI) RRC message a few times before. Generally I have always pointed people back to the LTE/5G specifications but here is a concise video that the telecoms technology training company Mpirical have shared recently:
If you want to dig further into details then please see the RRC specifications: 36.331 for LTE and 38.331 for 5G.
Over the years I have added quite a few short tutorials from Mpirical on this blog, do check them out below.
I have been meaning to share this video/presentation by Patrick Scannell for quite some time now. Pat Scannell is a technology and telecom industry consultant who is a world leader on 5G and the co-evolution of technology and cognition, specializing in innovation and commercialization of emerging technologies across a wide range of industries.
At the IEEE International Symposium on Digital Privacy and Social Media 2022, Pat gave a talk titled 'The Return of Magic: Technological Complexification'. The outline of the talk says:
Today’s tech is characterized by rapidly accelerating complexity, both in the densely layered technology itself but also in the increasingly hyper-specialized people who are needed to build it. But each person who builds it, and certainly most people who use tech, have a diminishing ability to understand how the whole of the techno-ecological niche we have created for ourselves (what I term ‘the return of magic’).
The case for this argument is outlined and then shows that the problems associated with this phenomenon are amplified by an inherent characteristic of a complex system - the lack of ability to know, understand, and predict system outcomes.
Against the broad scope of human history, the result of these forces could represent a reversal of a trend that started in the Enlightenment, but it also has very specific and actionable consequences on the day-to-day work of the tech industry and on Digital Privacy of our customers.
This talk aims to frame the problems, but in a constructive way that allows us to begin to build and adopt better technology, which could scaffold a better human experience.
The 3G4G Blog is our most popular blog, running for over 16 years with over 15.5 million views. With 2023 coming to an end, here are the top 10 most viewed posts from 2023 as well as top 5 most viewed videos. These posts/videos were not necessarily posted this year, so I have added the month and year each of them was posted.
5G Forum, South Korea organises Mobile Korea conference every year. Mobile Korea 2023 had two conferences within it, '6G Global', looking at 'Beyond Connectivity and New Possibilities', and '5G Vertical Summit', looking at 'Leading to Sustainable Society with 5G'.
I often complain about how organisations working in 6G often lack social networks skills, in this case, even the website is not very user friendly and doesn't contain a lot of details. Full marks for uploading the videos on YouTube though.
