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.

TETRA Pilot
I was surprised by the quality of the voice on the system. It even seems to have better quality than our analog system.

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!

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
