The purpose of the Neutral Host DAS is to rebroadcast cellular Carrier signals to achieve a minimum signal strength of -95 dBm RSRP and a Dominance Over Macro of 6 dB for all planned Carrier technologies throughout the building. This shall include at a minimum PCS and AWS frequencies in base bid option one, as well a consideration of -105 dBM RSRP and Dominance Over Macro of 6 db for an additional add-on option of 5G UWB, including 2.5 GHz N41, 3.45 GHz N77, and 3.7 GHz N77. a. Contractor is to assume the provided design meets these standards. b. Additionally, Contractor shall assume that the rooftop RSRP and SINR levels were evaluated and are acceptable to achieve acceptable BDA RF signal source functionality as depicted in the provided iBwave design c. The iBwave design, walk assessment, and supporting Carrier signal walk data will be provided to the winning bidder by Dakota County for their efforts in completing the requested SOW. 2. Provide a complete, Carrier and County approved, and full functional BDA fed Neutral Host DAS. Buildings and structures shall be equipped with an FCC-Part 90 Certified amplification system covering local cellular radio bands as defined in this specification. The head end of this DAS distribution layer shall be located in Dakota County’s desired IDF location as noted in the iBwave design and fed carrier signals via a dedicated Part-90 BDA per each Carrier as well as per each Carrier owned sub-band within shared frequency bands such as 1900 MHz PCS, 2100 MHz AWS, C-Band and as depicted in the provided iBwave design. The RF outputs of the separate Carrier BDA solutions are to be connected to the DAS per the iBwave design documents utilizing a dedicated DAS point of interface (DAS POI) and/or POI port. Each DAS POI or POI port must be dedicated to each Carrier and Carrier owned sub-band with no sharing of POI ports or POIs between multiple Carriers. Distribution active components of the DAS remote amplifier layer shall be located in County IDF rooms identified within the provided iBwave design and utilizing wall space dedicated for this purpose. Contractor shall coordinate with Dakota County to locate cabling, antennas, splitters, and any other edge devices throughout the facility in coordinated and consistent manner ensuring full aesthetic approvals and all applicable low voltage code requirements.
