New Public Safety Radio Repeater Law for 2019?

A 50 watt vehicular repeater with receiver diversity could provide a solution for the high rise fireground.

The problem is not going to be spraying RF into a building it's the low power portables getting back to whatever command site you are running. Plus just because in one incident you can use the lobby, maybe next time it could be the lobby is on fire.

You totally missed the receiver diversity part. With 3 RX antennas on the vehicular repeater you can improve the portable talk back easily 6 dB or more. You can even park support vehicles on the other side of the structure and link additional receivers with IP.

Heck, with equipment available today you can have a transportable two or three site simulcast system that could be set up in minutes.

I never implied incident command would be inside the building lobby. That was proven to be deadly in 9/11.

I did not realize there was a PS radio on the market with that feature. Very cool. Thanks!

The Hytera PD982 can record 572 hours of both TX and RX audio.

At the vehicle. Our local FD uses Icom F7510 P25 radios for IVR's, they record something like 500 hours of radio traffic to a micro SD build into the unit.

How does this method meet your agency/state requirements under open records? While these features are nice, they usually don't pass the sniff test if there is an incident and those recordings become part of an investigation. Reason being, their stored on media that can easily be tampered with by an end user. Not something I would rely on for logging of IDLH or any public safety communications.

The micro SD card is located in a locked cabinet, it is not easily accessible. It is not located on the front face of the radio. There is a dept policy for handling such media and only authorized personal are allowed to.

It is no different than in-vehicle DVR's that record to a storage device in the vehicle. Some systems upload to the server automatically but many small towns and city's can't afford that feature. It's actually a very effective way to record fireground traffic, especially simplex. I'd rather have it than have nothing at all.

Sorry to ignore the OP, but some the comments in this thread are comical. NFPA doesn't set regulations, they only make recommendations. Fire Marshal's and Building Departments enforce laws that City Council's adopt. In building systems are being pushed by NFPA, Fire Departments and Police. City Council's enact laws.

Work in a City that has 400++ BDAs pointing at one of your simulcast cells, and tell me its "easy" Adding more sites will never cover 80 story buildings, heavy construction, low E windows, buildings that are a block big.

DVRS/IVR---- Ha possibly, but how do make sure it shows up with the first due? What about a police response. Which one of the 350 police cars do you put it in? Only engines? What about the 10 Tiller trucks? How about the 50+ ambulances?

City of Trenton NJ was one of the first, it's requirement was less about the foot print of the building, more concerned about height and placement interfering in PS communications, like a large tall building blocking the path to an antenna.

Back in the early 1993 when they were switching to Motorola's first digital, 800 meg smart zone trucking system, they realized after a complete system design, but before the completed install, a building was built that blocked the signal to a portion of the City. So they passed an ordinance requiring any new building that interfered with PS communications was required to rectify the situation at the building owner's expense. Additionally, new building had to install at their expense whatever equipment was necessary to have PS communications work within their building.

Some buildings being planned adjusted their plan and/or materials, others installed equipment to boost or repeat the signal to outside the building.

Most outfits that were building new building and were required to comply with regulations just contacted the vendor that installed the City wide system for Motorola and let them install whatever was needed. That way there was never finger pointing that the system would not work because of someone else's equipment.

I am not a tech person, tried to explain in my terms.

We were the first that had the plain language requirement in our bid specs that if a hand held unit could speak from inside a building to a unit on the street outside the building, then the unit in the building MUST be able to communicate with the communications center. So if a walkie talkie in the 3rd level sub basement could talk to a walkie talkie on the street in front of the building, then central dispatch had to be able to communicate with the unit in the basement as well.
