Notes from the RCB Meeting earlier this week:
New Primary User: DHS
- Not day-to-day usage
- No dispatch operations
- 4 TGs enabled statewide
- 600 TDMA subscribers
- Important since their home system does not have coverage in the OC area
(notes: FIRST has mostly regional TGs, although some user groups have statewide TGs, like Comptroller)
New Primary User: CPB
- 5 TGs: 1 statewide, 4 regional (Baltimore)
- 100 TDMA subscribers
- Also wants TG sharing w/ MSP, MdTA, DHS, FBI, DNR, TSA, USCG, Air Marshals
(notes: Most Baltimore City subscribers are not TDMA compatible thus rarely use the system. Exceptions are the command bus and Foxtrot units.)
New Interop User: USPP
- 1000 TDMA radios
- TG sharing with MSP, MdTA, and other agencies
- Important for aviation / Eagle helos
New Interop User: Chester Co. PA
- Home system Harris TDMA
- Interops primarily with Cecil Co.
- 204 portable TDMA / 68 mobile TDMA subscribers
- Currently uses C-Comm system for interoperability (Southeastern PA Task Group)
Cecil Co looking at crosslinks for interoperability with New Castle Co DE
DE is slowly beginning to understand that their (janky) FDMA subscribers are a real problem when operating on FIRST, hogging 3 resources. New DE radios will be TDMA capable; reflashing existing radios will take several years
DE helos are TDMA
Newark radios are almost all TDMA
Cecil cutover this coming Thursday, 6am
Ethernet backhaul will be required for system 7.20; some local jurisdictions face a sizable bill. Discussion about who is responsible for the cost. Localities have incompatible equipment that enables local functions that are not directly part of the FIRST system, but will need to be upgraded to work with FIRST.
11 new RF sites are planned to fill in coverage "holes;" planning to fund 3 per year for the next few years
- Tower Road / Camp David ASR
- Cherrytown Chicken ASR (tower lease just signed, Carroll to provide backhaul)
- Table Rock ASR (site cleared, foundation set. Complete by end of year.)
- New Germany State Park ASR (prob use existing site)
- Crisfield ASR (going on county tower at Crisfield VFD)
- Nice Bridge ASR should be complete by October
- TV Hill ASR (fill in dead spot near Falls Road Light Rail) . MTA funds, April-May 2020 timframe
- Cecilton ASR (equipment in place, not enabled - maybe Thursday?)
System 7.18 upgrade March-June 2020
Syste 7.20 upgrade 2H2021, depending on ethernet upgrade status
CEN upgrade contiuing
Cecil move to Zone 3 complete with JFK and North East sites finishing migration
Cecil 2-channel upgrade in place to support GPS
Cecil LEOs - some users already on system; crosslinks between existing Cecil system to FIRST
Montgomery County simulcast cell being redesigned
OC ASR antenna relocation; want to raise transmit antenna, and move to a different tower leg to improve coverage in northwest Worcester. Current height is only 1/2 way up tower, will need to coordinate with Region 42 and new FCC license
Garrett County up and running, but the county needs to buy new radios; state loaning consolettes to enable usage
MTA 2ch upgrade to support Purple line. Discussion about the legality of using 700Mhz freqs for non-public safety users. Dorc hestewr has been denied the use for their MTA funded bus system. MTA Police will use 700; busses use 800Mhz, taken from port operations
McHenry Barrack transition on August 7th
