tions. We see, for example, the emergence of high-performance
coaxial transmission with 12G SDI, or ever faster HDMI
with HDMI 2.1. Connectivity has never been so critical.
Similarly, we also observe a multiplication of protocols supporting
IP networking, completing the standard ethernet offer.
A typical example is Single Pair Ethernet, which aims to bring
ethernet to new applications, where it was previously inconceivable
due to space and architecture constraints.
On the connection front of USB, USB-C is a great example of
the above-mentioned selection process. On top of unifying
many communication standards within one (i.e., HDMI, Display
Port, USB) form factor and supporting power transmission,
USB-C enables larger transmission speed, up to 40 Gbps
(USB 4). The combination of these two factors makes USB-C
the new champion, with other connections slowly losing the
battle, the striking example being Apple's Lightning.
The wireless world follows the same evolution, with Bluetooth
chip manufacturers offering higher data rate products
over short range up to 2 Mbps (Nordic). The evolution of Wi-Fi
toward Wi-Fi 6/6e is no exception, as this new version enables
higher throughput, even in densely populated areas.
IoT and 5G
The well-known statement that " 5G is the ultimate enabler
for IoT " has never been truer, and our thirst for data is ever
increasing. Use of AI is a typical example of cloud processing
capability over 5G. The emergence of new technological capabilities
together with the democratization of existing ones
paves the way for an ever more ubiquitous IoT. There are three
essential aspects in this wave of 5G democratization: interoperability,
increased bandwidths, and private networks.
Interoperability
is key for seamless and high performance
IoT. Many efforts have been dedicated to
making it more accessible and mainstream. An example
is the wider deployment of Open Radio Access
Networks (Open RAN or O-RAN). These
non-proprietary RAN are characterized by a disaggregation
of software and hardware, which makes
them all the more modular.
Another major trend in the context of interoperable
mobile communication is embedded SIM5G
has introduced higher global bandwidths and increased access to cloud-based
processing, e.g. AI, facial recognition, etc.

cards, or e-SIMs, permanently mounted into a
device. Their integration requires less space than
traditional SIM cards, making them accessible to
new devices. In addition, they have been designed
to support interoperability from the outset. On the
one hand, their specifications (data format and security
system) are standardized with that in mind.
