Notes from yesterday's RCB Meeting:
Limited Primary User Applications:
- US DHHS: 2 tgs for coordination of its disaster response mission set. 100 SUs. Approved.
- US DHS CISA: 1 tg for COOP / PACE resiliency (enc of course; this is CISA, lol)). CISA already has access to all NCR radio systems. Stated that IWIN doesn't work very well. 20 SUs. Approved.
- WSSC: 1 tg for coordination, but I got the impression that they want to operate on this tg primarily, rather than their 2 separate tgs on the MC and PG systems (which apparently are patched together). It seems to make sense as they operate in MC, PG and HoCo. 25 SUs. Approved.
- NCRCIG: The Communications Interoperability Group maintains a regional cache of 1,200 radios, portable BDAs and several SOWs that are available upon request to support contingencies in Region 20. FIRST will be testing one of the SOWs this spring. Requesting 1 tg for their techs, 100 SUs. Approved.

MoM - Manager of Managers software initiative. The FIRST system leverages infrastructure from jurisdictions and agencies throughout Maryland, and also owns its own equipment. The MoM will be a software "dashboard" that combines data from different management software packages used by all the players into a single view that can be accessed from a browser or front-end.

The current sole-source system maintenance contract with Motorola ends in November 2025, coinciding with the implementation of the MPLS backhaul network conversion. The state intends to have a new mx contract(s) in place by spring of that year. Note that there may be multiple contracts with multiple vendors - awaiting the inevitable responsibility finger-pointing...
---
Likely will be adding channel capacity at several sites as there has been a large increase in PPTs as a consequence of Zone 5 going live. 116K RIDs authorized on the system.
---
Staging for the MPLS backhaul equipment was completed in a warehouse in NC, and is being shipped to a FIRST warehouse in Baltimore County. This is where all the equipment was hooked together and tested for performance and compatibility (minus real-world paths). The NC warehouse lacked the electrical power to run Zones 1 and 3 at the same time, thus the Zones were tested seperately.

MSP has completed 2 of 6 barracks console installs needed to move their operations completely to FIRST. The completed barracks are LaPlata and Leonardtown. I'm guessing that Rockville, College Park, Forestville (or perhaps another barrack), and Prince Frederick remain, to be completed in early 2024.

Coverage improvement Program. FY2023: Sang Run scheduled to complete January 2024; Davidsonville and Greenbriar State Park in December 2023 - before Christmas. The Elmer School Road site has been dropped for now. A new Oakland site will be developed instead, also on an existing tower site.
FY2024: Patapsco State Park (greenfield) - planning phase. Queenstown SHA (greenfield) - planning phase, but may need to be re-sited. Looking for alternate real estate. Cumberland (greenfield) - planning phase. Located a site adjacent to I-68 that has a good "view" of the city. DC ASR is funded by a MWCOG Grant, working with DC peeps to get access for installation, hopefully to be completed by next Inaguration.
FY2025: Barton (Allegany); New Germany State Park - West (Garrett); Fire Station 30 (Cabin John VFD); St. Michaels (Talbot).
FY2026: Bretton Woods (Montgomery), Burtonsville (Montgomery), Accident (Garrett).
FY2027: Ourisman (Car dealer?, lol), New Germany State Park - East (Allegany), Harvey Gummel (Carroll).
Future / TBD: Charles, St. Mary's Dorchester, Flintstone (I already though there was a site here?), Montgomery County - West (replaces Elmer School Road.)
BDAs: FY2024: Talbot / Cordova ES. Two fire stations in Kent County that are having issues with simulcast distortion.
Geo-redundant Prime Sites. FY2024: Baltimore County. FY2025: Anne Arundel County.
Fiber. Ideally there should be two network paths to each tower site for resiliency. Some of these redundant paths were not constructed to save money, to be added at a later date when funding became available. FY2024: Cherrytown from MD97; Assateague to Ocean City; Denton to Federalsburg. FY2025: Sudlersville to Massey to Galena. Carole Highlands. Kent EOC to Still Pond. Mt. Savage.

FIRST infrastructure uses lots of batteries and lots of batteries need replacement.

The Dundalk MPA site is experiencing interference from an unknown source at tower top level, but is not observed at ground level. The FCC brought out their fancy monitoring truck but could not pinpoint the source. FIRST is considering a tower climber to go up with test equipment. In the meantime, some adjustments to site equipment were made to mitigate affects on the system. They will also replace site antennas to rule them out as a cause. Antennas are designed to last 15 - 20 years; these are about 12 years old.

Coverage issue in Baltimore. Apparently back in early fall there was an coverage issue with the Baltimore cell and MTA tunnels - the tunnels have BDAs that use leaky cables to distribute RF. There were reports of pockets of simulcast distortion that started above ground and later extended into the tunnels. The issue was traced to a bad TRAK GPS at one of the subsites that caused a timing issue. The GPS unit's status indicators did not show a fault nor did it trip an alarm. Motorola is investigating.
---
St. Michalels interference. The FCC did observe the interference and is soliciting more data / reports from those who experience the issue. The initial cause was traced to a BWC that transmits data over cellular data in a band space adjacent to the PS 700 band.
