We can
all breath again now that the official 5G logo has been announced! How many days
and nights have you and I spent wondering what it would look like and when it would
arrive (0 for moi)? Finally, here it is in all its
black and green glory (it actually looks pretty nice).
"The 3GPP has finally released an official logo for the 3GPP 5G specifications from
Release 15 onwards. The logo has a new wave pattern, and is based on the existing
LTE waves, using the green of the LTE-Advanced Pro version. The idea according to
3GPP, was to keep a familiar design aspect with ..."
Although not in the title as it used to be,
this is a "Mac's Service Shop" story by John T. Frye. If Mac and Barney
are the stars of the saga, then it can be none other. The story is about how the
misdeeds of a few dishonest operators can taint the reputation of an entire industry
- nothing new there. Barney is telling Mac about a 'sting' ploy pulled by a consumer
protection group whereby TV sets with a specific easy-to-troubleshoot problem introduced
to see how repair technicians from a suspect company would bill ...

"Scientists at the U.S. Northwestern University
have accidentally created a semiconductor junction with the newly-discovered material
borophene, that might offer a route to determining if it is electronically useful.
Borophene is a molecule made of boron atoms. Like graphene, borophene
is a two-dimensional sheet-like molecule, but thought to be a better conductor of
electrons than graphene. Unlike graphene, it is not thought to occur in nature and
so there are no handy lumps of borophite from which ..."

After spending four years as a USAF radar
technician, I do not recall ever hearing the term 'radician,' which, according to
this article and a few obscure sources on the Internet, is the name given to a radar
technician. OK, so I'm a former radician, but I digress. The DEW Line, or
Distant Early Warning Line, was a string of radar installations
running across the U.S., Canada, and Greenland, just above the Arctic Circle. It
was established to protect against potential attacks and/or surveillance by aircraft
and/or missiles from the U.S.S.R. Although the radar systems were ...
"The FCC's office of engineering and technology
has authorized the first

"Intel, Qualcomm and Samsung have issued
a flood of announcements all apparently designed to show how incredibly
5G-ready they are. Having regularly dropped the ball on mobile
over the past decade Intel is especially desperate to be seen as a viable 5G player
and is bombarding tech hacks with relatively open messaging intended to convince
us of just that. 'Intel is accelerating the 5G future,' wrote Aicha Evans, GM of

If you thought that
custom ringtones have only been around since the mobile phone,
you will be surprised to learn that according to this news brief in a 1956 issue
of Popular Electronics, Bell Telephone Labs was experimenting with such
features. Bell was exploiting the convenience, small size, and relatively inexpensive
transistor to enable customers with deeper pockets to hear something other than
the standard mechanical bell ringer. The irony is, of course, that some people nowadays
use a ringtone in their smartphones that sounds ...
"Semiconductors, as thin as a
single layer of atoms, are no longer a dream of the future: Researchers
in Germany, the United States and Poland have together developed a two-dimensional
material that could revolutionize electronics. Its semiconducting properties make
this material appear suited for advanced applications even much better than graphene.
The new material, introduced to the public in the scientific magazine ACS Nano ..."
Arduino has been a sensation in the techie
world for about a decade now. Not too long ago electronics 'starter kits' consisted
of a battery, a solderless breadboard, a handful of Rs, Ls, and Cs, LEDs, a neon
bulb, a couple simple ICs and transistors, and some jumper wires. Compare that to
this kit with an
Arduino microcontroller and code IDE, LCD, joystick, remote controller,
motion and ultrasonic sensors, stepper motor controller, keypad, RFID module, and
much more PLUS all the
stuff you got with the old type starter kits
- all for a paltry $60 (equiv. to $15 in 1977). Many add-ons available like an
übercool robotic arm ...

"The new antennas – including the 5-6 GHz
Adaptrix CMM200.A – feature a patent-pending,
modular interlocking system to help operators scale capacity –
when more capacity or speed is needed at a location, another module is clipped to
the side of the existing installation. This first-in-the-industry antenna system
means that when you need to add capacity, you simply attach extra panels. You can
build them up vertically or horizontally like Lego blocks. You don't need to worry
about spacing, alignment or ..."

Wireless power distribution has been in the
news a lot for the last couple years. It began with a goal of just
wirelessly charging mobile devices like cellphones, smart watches,
and tablet computers. Next came articles about charging electric cars wirelessly
while sitting in a parking lot or garage, or even at a stop light. In each instance,
the item being charged needed to sit in close proximity to an electric induction
coil to be effective. Just a couple days ago, however, a new item ...

"Now that the world has become addicted to
portable electronics, billions of people have come to see the companies providing
these gadgets as the most innovative, and the people who head those companies as
the most exalted, of all time. 'Genius' is a starter category in this discussion.
But clever and appealing though today's electronic gadgets may be, to the historian
they are nothing but the inevitable

When I first saw this picture of Dr. Martin
L. Klein, I though he was Superman. No, it doesn't take a superman to teach
electronics on television, but the familiarity of George Reeves as the star of the
"Adventures of Superman" series in from 1953 through 1958 would have been a good
reason to use him in the "Wires and Pliers" TV show. Dr. Klein and his techie sidekick
Aram Solomonian performed a weekly show presenting basic electronics to the audience.

When this story was written in 1938,
India was a country of roughly 2 million square miles, while the
48 United States had about 3.1 million square miles. Radio station growth in the
U.S. already had a 3-decade head start in establishing a nationwide network of broadcast
and receiving stations. Manufacturing of the required equipment was well established
within our borders. India, by contrast, relied heavily on outside sources for equipment
and the training of operators and servicemen. The U.S. never has ...

- and the resulting nonlinear junction. Even coaxial cable connectors than have
the same type of plating can develop scratches ...
While looking around the Web for good
job
search and career enhancement articles, an article by The Savvy Intern's Lauren
Kirkpatrick titled "Millennial Stereotype Busted: 'Paying Your Dues' is Bullsh*t,"

naively attitudinal (a 2013 graduate). However, she
does bring up a good point about how the world has changed from even as recently
as the 1980s when I first hit ...

Lasers Give Space Research Its
Broadband Moment
"Thought your Internet speeds were slow? Try
being a space scientist for a day. The vast distances involved will throttle data
