SCHNOOR indoor coverage radio systems for the public safety digital radio network

SCHNOOR indoor coverage (inhouse) radio systems for digital radio in accordance with the TETRA standard are available in all common supply variants or combina-tions of these:

• TMO(TrunkedModeOperation)repeater forcon-necting the property to the nationwide TETRA radio network including direct connection to the controlcentre.

• TMO-A (autonomous trunked mode) repeater inTMOmode,butwithoutconnection to thenationalnetwork.Itisnotnecessarytoswitchtheterminals,itworksasanautonomoussolutionnotrelyingonthenationalnetworkandoffersthefullTMOfunctionality.

What is indoor coverage radio?

Comprehensive radio coverage with digital the “BOS” public safety radio system is indispensable for the fire brigade,policeandrescueservices.Thefirebrigadesinparticular need this radio contact in critical applications in buildings and in structures such as tunnels or indus-trial plants. If the radio network does not extend farenoughintoabuilding,thelocalfireservicemayobligethe operator of the building to provide a radio system to extendcoverage.Theterm“indoorcoverageradio”hasbeen coined for this type of radio coverage.

• DMO(DirectModeOperation) repeaterasacost-effective solution for stand-alone operation without a networkconnectionexclusivelyonthepremises,nodirect connection to the control centre is possible,radioequipmentmustbeswitchedtoDMOmodebythe emergency services.

DMO/TMO

• Direct connection to the control centre available

• Requires the national TETRA network to be available

• Onsite command or vehicle need only a single radio

• Autonomous system without connection to the control centre

• Works without the national TETRA network• Terminals do not need to be operated in

DMO mode• There are three call groups in the building• Onsite command or vehicle need two

radios: one to communicate on site, one to communicate with the control centre

• Autonomous system without connection to the control centre

• Works without the national TETRA network• Terminals must be switched to DMO• There is only one call group available• Onsite command or vehicle need two

radios: one DMO to communicate on site, one TMO to communicate with the control centre

Statuatoryregulations,whichmayobligetheownersorusers of a building or structure to install an indoor co-verage radio system, can be found in the various localbuilding regulations. These building regulations, for ex-ample,stipulatethatspecificrequirementscanbesetouttoensureadequatefireprotectioninthecontextofplan-ning permission procedures concerning special structu-res(sportsstadiumsandshoppingcenters,forinstance).

In this context, themeasures that the owner or usermay be obliged to implement could include the installati-on and regular maintenance of an indoor coverage radio system to ensure communication within the building. The
