Sam Benzacar of Anatech Electronics, an RF and microwave filter company, has published
his July 2021 newsletter that features his short op−ed entitled "Wi-SUN:
The Most Pervasive Wireless Technology You May Not Heard Of," where he
notes "Like ZigBee,
6LoWPAN, Wi-SUN (doesn't even
have a Wikipedia entry yet) is based on the IEEE 802.15.4 standard and employs a
mesh-type rather than star topology, making it inherently self-healing. There is
no need for base stations because each node talks to the others, eliminating a single
point of failure." Not only haven't I heard of Wi-SN, but I haven't heard of WirelessHART
(HART = Highway Addressable Remote Transducer) or ISA100. Sam also presents some
relevant industry news items as well.

Wi-SUN: The Most Pervasive Wireless Technology
You May Not Heard Of
By Sam Benzacar
If you haven't heard of Wi-SUN, it's a good time to learn about it because this
wireless solution may just be the most widely deployed IoT communications technology
in the world. Now, you might be thinking, how can this be, when there are so many
other connectivity standards out there making similar statements? A likely answer
is that because Wi-SUN's primary target markets are field area networks in applications
such as oil and gas and utilities rather than "Industry 4.0" and home automation,
it doesn't get mainstream media attention. Let's take a look.
The initiative to create Wi-SUN began in 2010 with the goal of providing a communication
solution for interoperable smart utility field area networks that can span hundreds
or even thousands of miles with minimal infrastructure and potentially millions
of fixed endpoints. This places Wi-SUN in direct competition with the cellular industry's
Narrowband IoT (NB-IoT) and Low-Power Wide Area Network (LPWAN) solutions. A sponsoring
group called the Wi-SUN Alliance has developed a verifiable test and certification
program to ensure products from different manufacturers and work together. The alliance
has more than 300 member organizations in 46 countries.
Like ZigBee, WirelessHART, ISA100, SNAP, and 6LoWPAN, Wi-SUN is based on the
IEEE 802.15.4 standard and employs a mesh-type rather than star topology, making
it inherently self-healing. There is no need for base stations because each node
talks to the others, eliminating a single point of failure. There are eight main
subsets of IEEE 802.15.4, and Wi-SUN uses IEEE 802.15.4g for the physical layer
and IEEE 802.15.4e for the MAC layer. It operates in the unlicensed ISM bands at
915 MHz and 2.4 GHz and has a range of 4 km, although through the use of repeaters
its range can be expanded dramatically.
As is the case with its competitors, Wi-SUN is designed to allow endpoint devices
to operate with very low power consumption, which in its case is less than 8 mA.
It also has extremely low latency that is essential for mission-critical applications
in which every millisecond counts. When compared to LoRa and NB-IoT, Wi-SUN has
round-trip latency of about 0.02 s versus 1 or 2 s for LoRa and up 8 s for NB-IoT,
and its maximum data rate is 300 Kb/s versus 50 Kb/s for LoRa and 60 Kb/s NB-IoT.
When Wi-SUN was conceived, IoT was simply a concept, but today it's ubiquitous,
which means that Wi-SUN is now expanding its reach into other domains such as smart
cities in any other geographically dispersed environments in which reliable, simple,
long-range communications technologies are required. This is no doubt why the projected
growth of this technology is so strong. In fact, based on data from several market
research companies, its current global market value is more than $1.5 billion and
is growing at a rate of an impressive 25% per year.

Ericsson: 5G mobile subs will reach 580 million by year's end.
The 20th addition of the
Ericsson Mobility Report predicts that 5G will surpass its predecessors in terms
of adoption with about 3.5 billion subscriptions and 60% population coverage forecast
by the end of 2026. So far, more than 160 communications service providers have
launched 5G services and more than 300 5G smartphone models have been announced
or launched. 5G subscriptions are estimated to reach 1 billion two years earlier
than 4G did. During the first quarter of this year, 4G subscriptions increased by
approximately 100 million, exceeding 4.6 billion, equaling 58% of all mobile subscriptions.
It is projected to peak this year at 4.8 billion before declining to 3.9 billion
by the end of 2026.
FCC mandates better emergency alert technology
The FCC has adopted rules
to improve the way the public receives emergency alerts on their mobile phones,
televisions, and radios. The nation's Emergency Alert System and Wireless Emergency
Alerts are of increasing importance because of the increase in emergencies and disasters.
After a false emergency alert in Hawaii in 2018 that mistakenly warned of an incoming
ballistic missile, the National Defense Authorization Act for FY 2021 directed the
FCC and the Federal Emergency Management Agency (FEMA) to adopt rules to strengthen
emergency alerting. The FCC's Report and Order aims to ensure that this never happens
New vulnerability for Wi-Fi
According to a report in
Engadget, security researcher Belgian security researcher Mathy Vanhoef, well known
for detecting faults in Wi-Fi security, has discovered another one falling into
the category of frag attacks that result from faults in the Wi-Fi standard that
date back to 1997. Vanhoef explained that these flaws can be used to inject plain-text
frames into a protected Wi-Fi network that look like handshake messages. This allows
the hacker to intercept traffic by tricking the victim into using a malicious DNS
server. Vanhoef found that two out of four home routers he tested were affected
by this vulnerability, along with several IoT devices and some smartphones. Vanhoef
shared his discoveries with the Wi-Fi Alliance, which has been working with manufacturers
to update their devices.
DARPA wants high-power amplifiers to cook enemy electronics
DARPA is selecting participants
for its Waveform-Agile RF Directed Energy (WARDEN) project whose goal is to develop
high-power RF and microwave power amplifiers that can generate enough power to damage
or destroy enemy electronics. The agency also wants to develop computational models
to describe the coupling of electromagnetic radiation into complex enclosures via
unintentional paths like seams, apertures, and cable entry points, and to develop
agile waveforms that can also damage enemy electronics. It has three technical areas:
a high-power microwave traveling-wave amplifier, rapid assessment and numerical
generation of an electromagnetic response, and agile waveform development.
