800 MHz IX
Discussion continued about the Nextel sites in Bellingham, near the
YMCA and St Jo hospital, that Jerry Noe has reported about before, with coverage
issues and blanking out taxicab communications, generally about a block from
Holly and State St’s. Steve
Leonard provided Jerry a “project book”, the result of Nextel tests and work
to analyze the problem. Harlan
Ohlson noted very good cooperation from Nextel in working w/ WSDOT issues, some
of their 15 most important concerns list.
Wiz told of monthly meetings he has w/ Nextel concerning the King Co
group of 800 MHz systems and IX problems, and some help Motorola has been w/
radio modifications for Seattle. The
logistics is overwhelming, as 14,000 users to get modifications to all their
radios are not practical. Overall,
Nextel rates and received our sincere thanks for their efforts.
There was discussion about Motorola becoming more involved in
corrections, as Nextel is using Motorola’s equipment, and Motorola has
proposed technical solutions to the 800 IX issue w/ Public Safety 800 users, to
the FCC. Could Motorola “step up
to the plate” and fund some corrections?
Can WWCIC invite Motorola to discuss their engineering solutions at a
meeting? There normally is a cost,
as Motorola’s group charges their time as a consulting body to the Company
like they were an outside contractor. Perhaps
Steve Leonard and Wiz can look into that. Chuck
Zappala mentioned a web link to Motorola containing a “cookbook” on iDen
technology that might be available and a help to get into the details of it.
He will bring the info to next meeting.
Harlan reviewed some details of the EF Johnson gear the State uses on 800
for problems near Nextel sites. (OPEN)
700 MHz Planning
Meetings
Wiz reported. The last meeting was in Wenatchee over 6/24-26.
The conference line wasn’t usable.
There is a new DRAFT version 3 of the plans on the web site, and the
group is striving to get a semi-final version done by Sept.
They want to submit to FCC by Nov. Comments
on the drafts are welcome, and the info on the web site is extensive, w/ pdf
files there to print if desired. Comments
are solicited at the group meetings, and can be considered to incorporate, as
well as those made on the web site, to be reviewed at the next meetings. See the web for the meeting schedule, and consider
using the list-server. Sign up for
that, to receive the info by e-mail. They
meet at 1000, to allow traveling attendees to get there. Recall, they also try to set up the conference phone for each
meeting, to take call-in’s. The
phone number is (253) 512-7310. (OPEN)
The 700 MHz web sites are www.region43.org
for Washington State, and www.region35.org,
for Oregon, respectively. Contact
Jon “Wiz” Wiswell, Pat Buller or Kevin Kearns for more info. Meeting schedules and past meeting minutes are on the web
sites. Be sure to check them
for the latest information in this important planning step for both 700 and 800
MHz use in the future. (OPEN)
WWCIC web site
Alan Robinson will research a counter to be placed on our site to total
the number of visits that are made. What
about placing announcements and IECIC Minutes on the web?
If we do put some of the info we receive by e-mail onto the web pages,
we would need to strip off the personal data.
Our own minutes don’t contain the attendee lists, or much personal
information. Alan only puts the
text info or announcements on the pages.
It may bear further review before a decision.
(ALWAYS OPEN)
They
are: Sept 9, Oct 14, Nov 12 (Wednesday, due to Holiday on the 11th),
and Dec 9, all at WSP in Bellevue. Jay
Schmierer will confirm whether we can use the facility at WSP next year.
Other locations may also be considered.
Bring forth what you may suggest.
(OPEN)
(Sorry,
I can’t seem to get rid of this line below-LHP)
Unlicensed
technologies, Spread-Spectrum systems, and Noise Floor Measurements
Chuck Z told about the “blue zone”, a
concentration of “hot spots”, which he had told about earlier this year.
Using advanced antennas and technology, manufacturers are getting better
coverage by the unlicensed systems. A
“hot spot” was earlier thought to be about 200 ft or so, but now has grown
to blocks, and the “blue zone” adds to get distances up to ¼ or ½ mile
areas. Some active antenna arrays
can operate as 32 sectors, switch automatically, and affect the connected modems
like a cellular system. 802.22 specs cover the backbone to connect 802.11X
(“hot spots”) infrastructure together.
McDonalds have expanded trial systems back East, some hotels offer 802.11
coverage for free, as an incentive to patronize their facilities.
A question was raised about the status of Ricochet.
Wiz told about Seattle’s use of about 200 units on Ricochet before
Metricom went out of business. Everett
used 5 modems for a short time, but only the pole-top units still reside on
their poles, not active as no connection from the former WAP’s.
There are re-started Ricochet systems operating in Denver and San Diego,
but none known of locally. Puget
Sound Energy is using some 900 MHz spread-spectrum systems for meter reading.
Seattle looked at some use for telemetry and water controls, but didn’t
carry it forward, due to IX unknowns. Boeing
experimented with some, but the systems just locked up due to too much IX.
There is so much going on in the 900 unlicensed bands it is hard to
figure out. There are no guarantees
the systems will work reliably, coverage stabilities, and so on.
The line between Communications departments and Information Technology is
getting “fuzzier”. Gerry Broerman, Curt Kyle, and Harlan O, in addition to Chuck
Z, all commented. Wireless
broadband over power lines is another relatively new topic related to this area.
Several entities around the country are using it.
UTC has been promoting the technology, and has seminars dealing with
aspects of BPL. ARRL is strongly
against it.
Search on a number of web sites; look in “Google”
for BPL, or Broadband over Power Lines. (OPEN)
(From the May minutes) John Woodcock talked about
some problems with Quantar repeaters. WSP
has several hundred of the units. PL
frequencies, response problems, and repeater cut-offs due to different response
on PL tones are some of them. He is asking Motorola to help for WSP. Are any other members having troubles? What about phase shift?
He has contacted Fred Radovich, and he may be able to help escalate the
response. Wiz mentioned that
Motorola could be approached as a FRB item.
(Failure Review Board, which has weekly discussion, might get a higher
level of response). If it can get
into FRB, it goes before the VP’s on a weekly basis. The more users that bring the problem to Motorola, the better
the likelihood is, that they will respond.
Motorola may have special people to contact back in PA, but the numbers
are not readily available. Back to
the July meeting- Software Defined Radio, (SDR)- Steve Leonard made some comment
that Nextel has done some testing, worked on design, lab tests looked good, but
when attempted to put on the air, didn’t work that well in “real-world”
use. (OPEN)
FCC
Mike Rothe presented information from FCC.
He covered some infractions issued, and getting license renewal letters
from FCC. They are normally sent
out 90 days before license expiration, but may wander around at agency mail
sorting areas, as often names or positions have changed, and mail isn’t routed
correctly at the end user. If you
are aware of your licenses, be keen on the time periods to expect renewal
notices. Also check the ULS, as web
renewal processes work better now, than when first rolled out.
He told about the new 60 meter Ham band. There is lots of info about the new frequency grant in ARRL
letter, Vol 22, #21. There are very
strict rules for usage. FCC is
still working with tower paint and lighting violations, started back in 1994.
They are also pursuing SLAM, CRAM, and SPAM problems.
Most FCC documents can be found on FCC’s website www.fcc.gov.
If you would like help with documents, please contact Dennis Anderson.
Pat B mentioned more about BPL issues, where the technology is using
frequencies from 2-80 MHz. FCC
seems fairly non-committal on the issue. Great
potential exists for IX and noise on the present band uses, and the like.
Japan tried it, but shut down shortly after starting due to IX trouble.
There are around 12 companies that manufacture BPL equipment, per Chuck
Z, who recently did some web research.
Gerry
Broerman is retiring from Boeing in 38 days.
This is Gerry’s last meeting.
He will be going to Florida.
Thanks for Gerry’s many years of involvement in WWCIC.
Steve Mayes will be back in the area in mid-August.
We look forward to seeing Steve again at future meetings, and returning
to activity as our Member-at-Large #1.
Harlan O introduced Dennis Hausman, with WA State Dept of Information
Services, who will be working in the 700 MHz planning process, State radio
systems planning, and the SIEC, the State Interoperability Executive Committee.
Dennis told a bit about the SIEC focus.
There was a Pat B joke, as we have become accustomed to, and anticipate
at each meeting.
He seems an unending source for material.
(Sec/Treas smiles…)
(OPEN)
Meeting adjourned at 1105.
Next meeting is on Tuesday, Sept 9, 2003, at WSP in Bellevue.
See the WWCIC web page for details about our regular meetings and
directions to the locations. Thanks
to everyone for your interest and support for WWCIC.
Respectfully submitted,
Your most humble
