Blog Re-Launch!

Hello Everyone,

Wow.  A lot has happened since we last updated the blog!  Some of the bloggers had new children, a pleasant but time-intensive situation that removes creativity time to blog.  We have also been off learning more about TETRA, have gone to Europe in 2012 for training, and we have seen the FCC rule in favor of TETRA as a viable communications technology for US companies to evaluate.

In the next coming days, we will explore major happenings with TETRA.  I'll enjoy writing them, and I hope you enjoy reading about our experiences.

Quick Update - TETRA Events

Hello Everyone,
Summertime was full of vacations and TETRA activity, and we are excited to bring everyone up to date on TETRA happenings here in Green Bay – so check back soon.

Quick Update:

1)  I am currently attending a TETRA Association sponsored event in Fort Worth, TX.  Shortly, I will be presenting information on our TETRA Pilot here in Green Bay. I will be covering both technical and business reasons on why TETRA is so exciting to work with. I look forward to meeting and chatting with other people interested in TETRA.

2)  Upon returning to Green Bay, I hope to next week integrate data
communications onto the TETRA network. We know that TETRA can support
data communications, such as SCADA on the network, but we want to prove
it to ourselves that the process works.

Take care, and have a good rest of the week!
Christian

Webinar Complete, TETRA Demonstration Forum Next

Hello,
First, I'd like to thank those who attended our Webinar on Tuesday.
Thanks to those who asked some good questions, and I hope that you found
the presentation informative and relevant to your communications needs.

We will be having our TETRA Demonstration Forum in a couple weeks, and hope that many
will come and see TETRA first hand. PLEASE REGISTER HERE...Seating Is Limited.

We will be expanding on the material presented during the Webinar with more detailed information
about the equipment and performance options. We will also explore business concerns, such as what the system can do for a user, and things to consider before purchase.

But the big treat surrounding the Demo Days are the ability to put a radio in your hand, and use it. Make some calls. Setup a Gateway or repeater, and see how it works. We will even take a trip to the tower, if you would like to see how the system was installed at the tower site. Having a hands-on session really demonstrates the power of this system.Take care, and have a good one!

TETRA and Narrowbanding

Hello,

At the UTC show, we discovered that several companies that still had 25
kHz UHF licenses were about to "narrowband" them to 12.5 kHz to satisfy
FCC requirements. There is more to the story than just turning in those
valuable licenses!

TETRA uses a 25 kHz channel, and digitally divides that channel into 4
separate conversations, each 6.25 kHz wide. Thus, a TETRA signal on
your 25 kHz channel qualifies as a narrowbanded emission, and it is
fully legal and compliant with the FCC Narrowband requirement.

With TETRA, your channel will allow 4 separate conversations, depending
on the configuration of the system. Each base station has to have 1 time slot/conversion for administration and texting functions.

The goal of the FCC is to replace older FM-Wideband 25 kHz conversations
with more efficient 12.5 kHz emissions, meaning that the space 1
conversation used to consume will now allow 2 conversations. With
TETRA, you can double that efficiency, with 4 possible conversations
ongoing at the same time. That's quite a deal, when you consider the
cost of filters, repeaters, and antenna space.

So, if you have 25 kHz licenses, and would like to find out more about
TETRA, please give us a call or an email: 920-494-1828 or
tetra@nielsoncom.com
Thanks,
Christian

UTC Show

Hello,
We had a wonderful time at UTC! Thank you to all of the folks who
stopped into see us at Booth 853 for discussion. We found out there is quite an interest for TETRA concerning utilities, and it felt wonderful to talk with excited representatives from various companies.
Thank you for stopping in to see us.

The show went well, and we were able to demonstrate TETRA with a live
connection to our pilot system in Wisconsin. Visitors in California
were able to hear traffic in Wisconsin, and able to talk with our
employees as they drove about their daily tasks.

We demonstrated telephone functions using a VoIP telephone installed at the booth. We
also found that a base station transmitting 600 mW (milliwatts) was able
to talk to a portable radio through several feet of steel and concrete
-- the base station was in a basement, and we were walking around
outside testing the signal ranges.

I wonder if a full watt would have reached the hotels where people were staying. We also demonstrated AVL
and Dispatcher technologies.

Take care, and catch you soon!
Christian

TETRA Waiver Granted

Hello,

Very exciting news came forth from the FCC concerning TETRA -- the
waiver is granted, and we can now present the technology that 114 other
countries use to interested people in the United States. No longer a
"science project", we now have the ability to form a business
relationship, and work with perspective customers to try out the
equipment, and see if it solves their problem.

Frequencies authorized include the 450 - 470 MHz band, and 817-824 and
862 - 869 MHz bands. Because TETRA audio is all digital from the moment
a Microphone catches it, it should be possible to talk in on 450 MHz,
and also reach people on 800 MHz. I want to try it, as there are places
where 800 Mhz would be useful, such as building penetration. More to learn!

In the early days of the pilot, we did show some interested parties the
radio system, but we had to disclaim that the system is not available
for sale. It's hard to show a superior technology, and generate
interest, but not being able to deliver the interest to the customer.
The customer can also now try the product, and know that it is not a
waste of time, as there is a means now to obtain the system and upgrade
what is presently in use.

Time to get ready for the UTC show coming up in a little over a week.

Christian

Preparing for the UTC Show

Hello,

After a very enjoyable Media Day presentation to communications users in
Green Bay, we are busily preparing for the UTC show in May being held in
Long Beach, California. I am preparing items for the booth, and working
with Suzzan, our creative media genius, to prepare the charts and make
sure all of the pamphlets are in order, ready to go. We are going to
bring some hardware to the show, and hope that interested folks stop in
and see several types of radios, and identifying how TETRA can solve
their communications problems.

In the last week or so, we also modified the home network to accept
incoming group calls. This is an exciting feature of TETRA -- allowing
a person on a land or cell phone to call into a radio system, and talk
to a group of people at the same time. Thus, if I was a supervisor, and
needed to dispatch someone from home to take care of a problem, I could
pick up my telephone, and call the radio system, and interact with a
group of employees. That's very useful!

Looking ahead, I am building a System Manual of our setup, to bring
together all of the related commands and programming of the TETRA system
that we have running here in Green Bay. I'd like it to be a one-stop
reference for anyone who would like to know the details of the system.

US TETRA Pilot Seminar - Media Day Slideshow

Media Day - April 5 and 6

It was an extreme pleasure to welcome members from the TETRA
Association, along with partners Rohde & Schwarz and Sepura, to Green
Bay, for two days of incredible TETRA discussion with guests new to the
technology.

We began our presentation around 11am, and after some
introductions and high-level material, broke for lunch, and returned to
the meeting room for afternoon demonstrations of the technology. I
never had Texas-Toast grilled cheese before; that is quite a treat.

I am professionally elated that all of the technical subsystems, such as
the VPN, Dispatcher, and AVL solutions, functioned properly out of the
box, and we were able to demonstrate TETRA features without interruption.

On Wednesday, we invited everyone to our Green Bay facility, where we
went into technical detail about the TETRA system. We explained how
TETRA worked internally on Rohde & Schwarz hardware, and how we
configured the Sepura terminals. We also gave hardware to our guests to
turn the radios on, and get a feel for them.

This week, we are preparing our presentation for the UTC conference in
Long Beach, California. If you are coming to UTC, please stop in and
see us!

Tetra helps Work From Home

Hello,
Winter struck back at us here in Green Bay, and I was snowed in on
Wednesday. But, I had Tetra with me, and returned several support phone
calls to test the radio - telephone interface.

I was able to call other staff that was working at home, and troubleshoot their computer
questions. People I called said that I sounded just fine, and they
could not tell that I was on a non-telephone. I am going to coin this
process as "Tetraphone" and am glad that I could use the system in this
fashion.

Tetra work continues on with verifying the range of the system within the Green
Bay metro area. We are also preparing presentations on the system, and
preparing for our first major outside vendor to try the system out.

We had a positive experience at IWCE, and are looking forward to the Media
Day coming up in April.

Next Tetra Related Goals

Hello All,
During the second week of March, we have set some goals for our Tetra Pilot.

1) Successful demonstration of Tetra Dispatcher console at IWCE. We
took the special laptop to the show, and would like to demonstrate for
show exhibitors what the system can do from the show.

2) Incorporation of the Tetra telephony into the Office telephony.
There are two Asterisk boxes involved, and I would like to setup a trunk
so that a Tetra terminal can call an office extension. We have
dedicated phones working now, but how about a complete integration with
an existing office phone network?

3) Incorporation of the tetra telephony and an outside telephone line,
full time. I tested this a couple weeks ago using the fax line, but I
had to give the fax line back. I would like to install a full-time
connection to the outside telephone network, and examine calls working
in both directions. I don't think outbound calls will be a problem. It
should be "dial the number, and go." Inbound calls could be a
concern... the Asterisk box will need help routing the call to the
proper radio terminal. It is my gut guess that I will need to setup an
IVR (computerized dial 1 for this, dial 2 for that, dial 3 for someone
else) and route the call from there.

Lots of good stuff ahead!
Christian

First Week of March

Hello All,
Tetra system evaluation continued this week, building on the successes
of Feb 23.

Because full-duplex calls utilize more system resources, they are ideal
for detecting system range from the base station. We drove out to
fringe areas, and made some phone calls to voice mail to record
ourselves, listening for any drop outs or system failures. We didn't
detect anything out of the ordinary.

We also installed external antennas at our main office to work with the
Tetra radios. We are inside a completely metal building about 8 miles
from the tower, and that was causing some signal loss. This too is
expected, as the analog system suffers from the same RF rules and
constraints... an analog radio has the same challenges getting into the
repeater as the Tetra does.

On March 3, I built a VPN circuit so that the Dispatch laptop could now
be used outside of the local network, allowing for a demonstration
anywhere internet connectivity is available. We tested the setup with a
full duplex telephone call, and walking around the office listening to
it via a wireless network.

Finally, we welcomed Alexander from Rohde and Schwarz to Green Bay. He
is a Product Manager for Accessnet-IP, the large-scale Tetra system, and
he visited our installation of the pilot system.
Until Later,
Christian

Very Successful Day - Feb 23

Today was a very good day for our Tetra pilot in Green Bay.

1) We resolved the telephone interface problem with the Tetra system.
Put simply, the testing phones I was using had extension numbers 800 and
801, and the Asterisk interface was told to send calls beginning with an
82xx or 83xx to the Tetra computer. I fixed the problem by changing the
extension numbers to 400 and 401, and the problem vaporized. We now
have bi-directional calling internally available. I will be working on
a full-time POTS connection in the near future, but for now, people on
the radio can call the people in the office, and the office can call
people on the radio. The audio levels were clean with outstanding
clarity! Tomorrow, we will work on a video demonstration of our success.

2) We setup and activated the Dispatcher station on the Tetra network.
Working with a software vendor, we obtained trial copies of a Dispatcher
solution that works over an IP network to interface with Tetra. Using a
headphone and microphone solution, we can now make "calls" onto the
radio network, and interact with radios in the field. We performed full
duplex (like a normal telephone) and half-duplex (like walkie talkie)
calls with the system, along with sending SDS (text) messages through
the interface. The Dispatcher logs those messages.

Take care, and I'll write more soon.
Christian

Very good week!

Hello Everyone,
Last week, we had some wonderful things happen with our Tetra pilot.

1) We performed the analysis of Tetra vs. Analog performance at extreme ranges from the towers, and found several instances that when the Tetra digital first began to break down, that the Analog at that range was very scratchy and unstable to almost unusable! This is rather incredible, as the Tetra systems were transmitting about 10 Watts, and the analog was in the 25Watt range. One would think that more power is always better, but we have found cases where we have similar performance without the power penalty and exposure. As this is rather unbelievable, we are going to make a video of our observations to share with you all.

2) We took some portable radios and removed them from the Tetra base stations. We put them into DMO mode (direct without a repeater or base station) and performed conversations. This coming week, we want to work with a mobile in Gateway and Repeater modes, and see how well the signals replicate through the radio. Because this is all digital, the replicated signal should be much closer to the original source. Let's try it!

3) We assembled our real-world driving data, and compared it to a
propagation study, and found that the two data sets are quite similar. The real-world tests were better than the calculations, but then again, it is winter time here in Wisconsin, and the leaves are off of the trees. Signals will be dampened once the leaves return.
Take care, and I'll write more soon.

Christian

Goals for Week of Feb 14

1) We are continuing work with the integration of the telephone system.
I am sending the configuration files to the manufacturer for analysis on
why phone calls cannot be made from a landline to a Tetra radio device.
I feel that I am very close to cracking this puzzle, and once it is
done, I plan on installing a couple phones in the office so that people
in the field may call into an office person and talk.

2) Real-world drives continue. One person on Monday took a mobile unit
to Marinette / Menominee, and we are collecting data on that travel, so
we may investigate our range to the North of the tower, over the Bay of
Green Bay. We are also starting the model analysis, and I hope to
report more details on that mid-week.

3) Backup systems are made, however I have not scripted them yet for
automatic execution. I am glad to have a snapshot of the setup, but a
complete and refreshed backup remains the goal of the system.

I also had the pleasure of testing a Tetra portable at the reception of
the Super Bowl Champion Green Bay Packers on Monday. As our office is
located near the stadium here in Green Bay, when the team flew into the
airport, I took a walk to the stadium, and with a large collection of
fans, welcomed the bus parade into the stadium parking lot. Portable
coverage worked really well, and it was windy, with 20 or so mph winds
(the flags were rather extended, but not rigid) and temperatures in the
mid-teens.

More on TETRA Voice Quality

After having had a chance to use the TETRA equipment in my service van
while driving around the Fox Valley, I have to agree on the audio quality.
I have operated most digital modes like P25, TRBO /DMR, NXDN / IDAS,
even D-STAR.
TETRA has by far the best recovered audio I have heard from any digital
mode.
For those of you familiar with those other digital modes, you are
probably used to hearing a lot of digital "artifacts" and occasionally
"gargling" or metallic sounding recovered audio. TETRA seems to do a
superior job of reproducing a more natural sounding voice than any of
the other digital modes. I am impressed.

NCI and TETRA in Radio Resource International

The TETRA system will comprise three IP-connected base stations from Rohde & Schwarz and more than 30 Sepura TETRA radios. The network will demonstrate the features and functionality of TETRA technology, along with showcasing vendor interoperability and the power of TETRA-enabled applications, a Sepura statement said.
Three local utilities have expressed interest in the technology, said Rick Nielson, president of Nielson Communications. He plans to supply the utilities with mobiles and portables and allow the utility staff to test the coverage. "Basically I’ve been watching this technology for 10 years, and it’s really interesting. It’s amazing actually," Nielson said. Complete Article: Link to Radio Resource International

Goals for Week of February 7

Work continues well for our TETRA Project, and we have some goals for this week.

1) Continue working on hardware integration with the telephone system.
One of the valuable features of the TETRA radio environment is that it will interface with the telephone system, allowing authorized radio users the ability to make a phone call through the radio system. We have radio to landline working, and are in the process of finalizing the configuration of a landline
person calling a radio device.

2) Continue real-world drive tests documenting signal strength.
We have data collected and will continue to gather and document additional signal strength test as well as verifying our RF plots with ground truth reports. I hope to analyze these details later this week and compare them with the analog system already installed at the base station locations. This means we can compare the radio styles, as the analog system uses the same antenna system as the TETRA systems.

3) Collect our documentation, and generate backups.
Want to demonstrate that with light effort the system is robust and can tolerate equipment failure.

Tetra Blog

I am Christian, the IT Network Engineer at Nielson Communications, and I
am excited to be working on the Tetra program here in Green Bay. I am
the Project Manager for the program, and I am also responsible for the
infrastructure design and implementation of the base station units. My
goal is to deploy the units (which we have done), and configure tools to
measure their performance, creating a baseline that we will build upon.
I am also heavily involved with the RF propagation analysis, so that we
may accurately predict where the system will work, given an arbitrary
distance from a site.

Tetra voice quality

I am impressed with the voice quality of the Tetra system.

Very clear and crisp.

1st United States Press Release for the Green Bay, WI TETRA Demonstration

Sepura, Rohde & Schwarz Professional Mobile Radio and Nielson Communications to play major role in first US TETRA demonstration project.

Sepura, Rohde & Schwarz Professional Mobile Radio and Nielson Communications announce their participation in the very first TETRA demonstration project to take place in the US. 

The project is a pilot for TETRA being carried out under the auspices of the TETRA Association, and will be a close collaboration between Sepura, a global leader in the supply of TETRA radios, Rohde & Schwarz Professional Mobile Radio, a subsidiary of Rohde & Schwarz and leading TETRA infrastructure provider and Nielson Communications, an American mobile communication specialist organization.  It will demonstrate the extensive features and functionality of TETRA technology, and will also showcase vendor interoperability and the power of TETRA-enabled applications.  The TETRA demonstration will be open and accessible to potential PMR (Professional Mobile Radio) users in the US.

The TETRA system will comprise three IP connected base stations and more than thirty Sepura TETRA radios, and will go live in Green Bay, Wisconsin on 19th January 2011. Prospective customers will be able to attend seminars on the technology and its benefits throughout the six months of the demonstration. 

TETRA is the most successful digital trunked radio standard in the world. Phil Kidner, CEO for the TETRA Association, said: "We are delighted that this TETRA trial in the US will enable potential users to experience and evaluate the technology. As the worldwide industry representative for TETRA, we are committed to bringing the benefits of TETRA communications to the widest possible user base."

Rick Nielson, President of Nielson Communications, said: “TETRA is a proven, open standard, quality driven, advanced digital radio technology which exceeds the US narrow banding requirements (6.25 kHz equivalent) and embodies the FCC’s goals for increased spectrum efficiency.  Since the first generation of TETRA networks were deployed in 1997, hundreds of TETRA networks have been implemented across the world supporting hundreds of thousands of TETRA radios. TETRA has proven to meet and exceed customer needs world-wide in a broad variety of sectors, from public safety to transport, utilities and military. To date TETRA has been adopted by 114 countries around the world. We are excited to be able to show TETRA’s capabilities to our local, regional and national clients”

Steve Nielson, VP of Nielson Communications added: “TETRA will have a significant impact on the PMR industry in the US by providing a digital solution to the thousands of current analog radio users, offering features and applications not currently available in the US at cost effective pricing. It is because of the open standard developed by the European Telecommunications Standards Institute (ETSI) that innovation has been able to flourish between TETRA manufacturers throughout the world, while at the same time driving down user costs. We are extremely excited to be part of this project and to be able to work with the TETRA industry leaders Rohde & Schwarz and Sepura”.

Dr. Georg Haubs, Managing Director for Rohde & Schwarz Professional Mobile Radio, added: “We are extremely pleased about the opportunity to support this TETRA demonstration initiative and to introduce our TETRA infrastructure products live to US users. Mobile communications systems have to be designed around customers’ needs.
