Life After Nokia

Nitin Dahad
16 April 2019

The demise of Nokia's mobile phone business rocked Oulu in
Finland, but the city reinvigorated itself by becoming a low
power radio technology hub. We examine how the city
recovered, and survey some of the companies that emerged.

Nokia was once the biggest employer in Oulu in northern Finland.
When the company closed its mobile phone business in the 2012-13
timeframe, almost 7,000 Nokia staff suddenly had no jobs and no

This is where the deep radio heritage from the local universities
and expertise in designing and manufacturing mobile phones with
Nokia for many years came in very useful.

Low power and high-performance radio will continue to be key
factors in electronics systems, particularly with "smart things"
that rely on connected devices and the internet of things (IoT).
For example, with 5G the effective use of energy and accuracy of
beam forming will be critical in improving technologies and
systems. ...

KNL Networks

A spin-off from the Center for Wireless Communications at the
University of Oulu which is also leading the country's 6G
research KNL Networks' founders had deep collaboration with
Nokia. It's using shortwave radio to deliver its own independent
mesh network providing reliable worldwide military-grade IoT for
the maritime industry. KNL Networks uses proprietary technology
high frequency (HF) radio to form a global mesh network. Ships at
sea can make a cellular connection with another ship at port with
a KNL device, with a range of roughly 10,000 kilometers. This is
critical in maritime cybersecurity, especially with increasing
risks, as highlighted by the infamous Maersk shipping hack.

The company started when three people met in a sauna very
common in Finland and had an idea that they could utilize
modern communications in the HF band. Two of them were radio
amateurs, the other in military communications research.

Pocket-sized VLF antenna keeps comms open where conventional
radios fail

David Szondy
14 April 2019

The US Department of Energy's SLAC National Accelerator
Laboratory has developed a compact antenna that can transmit
radio signals not only over long distances through the air, but
also underwater, and even through solid earth. The new four-inch
(10-cm) antenna exploits the piezoelectric effect to generate
Very Low Frequency (VLF) waves that normally require antennae
that are miles long.

If you ever travel to the Pacific Northwest town of Arlington, WA
and look toward the Cascade mountains on a clear day, you'll see
12 huge red and white towers set on either side of Jim Creek
Valley. Their purpose is to hold up a cats cradle of cables, each
spanning one to 1.6 mi (1.7 to 2.6 km) from one slope to the

Built in 1953, this is Jim Creek Naval Radio Station and is
designed to allow the US Navy to send one-way messages to
submerged submarines using VLF radio waves at 24.8 kHz. This
gigantic antenna is necessary because in order to send and
receive radio waves the antenna needs to be comparable in size to
their wavelength. In VLF, these are miles long.

Needless to say, this makes the setup not exactly portable, but
it fulfills a very important function. Conventional radio
transmitters work very well over short distances, but not over
long ones, and they are easily blocked by rock or water. However,
VLF radio waves are reflected by the Earth's ionosphere and can
travel through the Earth and even into the deep ocean.

VLF communication doesn't have much bandwidth. For submarine
communications, it doesn't send so much full messages as a "gong"
signal telling the captain to go to periscope depth to use
shortwave or satellite communications. But it is a way to stay in
touch with nuclear submarines while keeping them well out of
sight of hostile sensors.

The SLAC antenna allows for a much more compact transmitter that
weighs only a few pounds, yet is 300 times more efficient than
other compact antenna designs at a test range of 100 ft (30 m),
and with 100 times greater bandwidth.

To achieve this, SLAC says that the new antenna uses the
piezoelectric effect. A rod-shaped crystal of a piezoelectric
material, lithium niobate, is subjected to an oscillating
electric voltage, which causes it to vibrate and send out VLF

This allows it to not only send out very large waves, but to do
so without large tuners. By switching the wavelengths, data
transfer rates can be boosted to more than 100 bps.

"Our device is also hundreds of times more efficient and can
transmit data faster than previous devices of comparable size,"
says SLAC's Mark Kemp, the project's principal investigator. "Its
performance pushes the limits of what's technologically possible
and puts portable VLF applications, like sending short text
messages in challenging situations, within reach."

The research was published in Nature Communications.
