Before the Board of Public Works Tomorrow....

Using Agency: Department of Transportation, State Highway Administration
Description: Supply and install conduit and fiber optic cable to support phone and
internet communications systems for emergency preparedness services.
Location of Work: Prince George’s County, Upper Marlboro City, Off ramp at Water
Street (MD717) and Pennsylvania Ave (MD-4)
Pennsylvania Ave (MD-4) east to Crain HWY (US-301) exit ramp
Crain HWY (US-301) north towards WSSC Treatment Plant Road.
WSSC Treatment Plant Road to SHA Radio Tower.

This is a Cable and Wire DoIT Master Contract project to connect Maryland First Radio
System, Network Maryland, and SHA shops to the MDOT Network. This will connect all
the state agency first responder radio’s to MDOT and some counties to MDOT as well.
This project will enhance a section of the fiber backbone network for the MDOT Enterprise
Network as well as enhance Maryland’s First 700 MHz. The fiber will enable connection
of SHA and MDOT network equipment on WSSC Treatment Plant Road SHA Tower to
the MDOT Enterprise Network. This project will include installing conduit and fiber which
will be terminated at specified end points or/and spliced in the fusion splice tray in the
manholes.
Not a very long segment, maybe 2.5 - 3 miles. Seems a shame this might be holding up the SoMD counties coming online.

The new target go-live date for all Phase 5 counties is November 15, 2021. This date accelerates Montgomery and Prince Georges counties, and delays the SoMD counties by a few months, respectively. The Westminster ASR conversion to a prime site with new subsites in Taylorsville and Sykesville will happen sometime in early-ish 2022, with the simulcast cell initially consisting of Westminster and Sykesville, and the Taylorsville subsite coming online later. The Swallow Falls site in Garrett County will likely be located at a commercial tower site, and the LaVale site has a purchase order for equipment in the approval process at DGS.

The Safety Drive tower site is moving forward with raising the transmit antenna height to improve coverage of the Queen Anne Simulcast in the Grasonville area. There are other tower sites in the system that also have large differences in TX vs RX antenna heights, and some of those are being re-evaluated to improve coverage. I had previously thought that the QAC simulcast cell had sites at Suddlersville, the MSP Centreville Barrack, and at Route 18 Park, but it turns out that the "Safety Drive" site is located at the MSP Barrack, and the site at the park is one of the old UMESC sites. That means that the QAC Simulcast cell consists of only two tower sites.
