You must upload documentation confirming use of a Control Channel frequency provided by the Orlando Police Department and a grid report from a Communications Specialist Integrator who possesses an FCC issued (GROL) General Radio/Telephone Operators License. The survey report must include type of analyzer and or technology, (DL) download and (UL) upload calculations for inbound and outbound transmission, DAQ (Delivered Audio Quality) and a grid report of frequencies for every floor.
Signal Strength.
- Inbound. A minimum inbound signal strength of −95 dBm shall be provided throughout the coverage area. The inbound signal level shall be sufficient to provide a minimum of DAQ 3.4 for either analog or digital signals.
- Outbound. A minimum outbound signal strength of −95 dBm at the donor site shall be provided from the coverage area. The outbound signal level shall be sufficient to provide a minimum of DAQ 3.4 for either analog or digital signals. Isolation shall be maintained between the donor antenna and all inside antennas and shall be a minimum of 20 dB above the signal booster gain under all operating conditions.
Critical areas. Critical areas including fire command centers, fire pump rooms, exit stairs, exit passageways, elevator lobbies, standpipe cabinets, sprinkler sectional valve locations, and other areas deemed critical by the AHJ, shall be provided with 99 percent floor area radio coverage.(NFPA 72; NFPA 1221)
General building areas. General building areas shall be provided with 90 percent floor area radio coverage. A spectrum analyzer and/or other comparable technology shall be used to ensure adequate reception and transmission of signal is not violated by other unauthorized carriers. The choice of technology used shall be identified in the report. Use of City of Orlando agencies; Police and or Fire Department to establish the required minimum frequency is not applicable to this test.
In compliance with NFPA 1.11.10 properties who submitted Grid Reports as proof of coverage will be required to demonstrate minimum radio strength annually or at the request of the AHJ. The use of handheld radios as the sole primus to demonstrate compliance with NFPA 1.11.10 is prohibited.
