RoIP

[DS0038]

Has anyone had experience with using RoIP for in building issues? We are a PD on an 800MHz, encrypted, repeater network, P25 non-trunked system. The schools in our town find a DAS cost prohibitive. I need to help get the officers radio signals out of the school building dead zones to hit the nearest receive site. I was told Motorola's Smart Connect is only available for trunked systems. I have seen some Rayethon RoIP products, wondering if anyone has experience with RoIP in this application. Thank you

They could put remote receivers in the schools and use ROIP as the “wireline” back to the comparator if it’s a voted system.

Another option would be low power repeaters at the schools that would act like smaller sites or cells that could be part of the larger system. If simulcast , could make timing a bit challenging. But can be done.

There are many ways to skin that cat, but ultimately the school or the system AHJ should be bringing in professionals to look at every aspect and come up with solutions.

If it’s a serious concern, then the funding should be made available and done correctly.

I agree, they build nice buildings and should consider DAS as part of life safety, but they don't. Thank you for the information, it helps.

It is a voted system.

Another option is a “raven blade”

What is a raven blade/where can I get info on it?

Thank you

That is correct.

They could easily put a dedicated RCVR , or even a mobile using a ceiling mount antenna in the problem spots of the schools, tie it into one of the many gateways on the market , and feed it back to the comparator for whatever channel on the system.

As for the backhaul from the school to the site, they could do an air mux, one of the many microwave links available if there is line of site, they could use a T-1 from the school to site, cradle point or another cellular type, a tunnel over public internet ( that would be last resort).

There are many ways to do it , but all will cost something.

Thank you, I appreciate it.
