1 1.3 Current Radio Systems General Question Can the Klein ISD verify if the repeater frequency pairs used at the high schools and intermediate schools would be available for the system if they can be relicensed appropriately? KISD intends to continue use of the frequency pairs used at the high schools and intermediate schools during the transition to the new trunked radio system. Vendors should assume the aforementioned frequencies will not be available for use on the new trunked radio system Regulatory Considerations 1. Klein ISD desires a radio system operating in the land mobile radio (LMR) UHF frequency band with microwave radio links for system connectivity. Klein desires that the proposed UHF channel frequencies all be Exclusive Use (FB8)" FCC licensed channels New System Cutover A well thought out and detailed design and system cutover plan must be developed by the selected Vendor in cooperation with the District to ensure the continuous operation of both the new and current systems throughout system cutover Future System Expansion Though the initial system will be configured with 7 talkpaths plus the control channel, it is still necessary for the Proposer to explain what will be required if the system needs to be expanded in the future and how such expansion would be accommodated. Does the KISD anticipate FB2s non-exclusive channels to be allowed anywhere in the proposed system? Could the KISD further define their desire regarding the FB8 channels? Does KISD prefer cutover activities to occur during the school year or summer break? Would there be a timeframe preference for transportation or facilities? Can the KISD confirm that it is requesting a minimum of (4) FB8 channels per site, depending on vendor technology? It is KISD s desire to have licensed frequencies free of all interference for co-channel licensees. Exclusive use channels are believed to be the best way to insure the new system will be free of interference. Note that KISD is eligible for both Industrial/Business Pool and Public Safety frequencies. It may be possible to use frequencies for both pools provided that the FCC grants permission. Vendors will be required to obtain permission from the FCC to allow such operation by KISD. Cutover for the KISD Transportation Department will need to occur during the summer break to allow adequate time to install all the mobile radios in the school busses but the remaining radio users could be cut over to the new radio system as soon as final system acceptance is successfully completed. Yes it is still necessary for the Proposer to explain what will be required if the system needs to be expanded in the future and how such expansion would be accommodated. Should KISD elect to implement additional channels after the initial system is installed they need to know what additional hardware, software and licenses would be required to do so. For example, if KISD want to add one additional channel they may need a new transmit combiner, receiver multicoupler, power supply, router, switch and additional software and licenses to do so, or the proposed system configuration may accommodate one additional channel by merely installing another transceiver. Vendors should clearly explain exactly what is required for each stage of system channel expansion and also explain exactly what is needed to add more repeater sites in the future.

2 2.4 Trunked System Features and Functions 2. Individual or Private Call: Selected users and dispatchers shall have the ability to selectively communicate privately with another individual on the system regardless of what talkgroup either unit is in. The call shall allow the two users to utilize a single channel resource to communicate without the participation of other units in their respective talkgroups. 9. Call Alert: Selected users and dispatchers shall have the ability to selectively alert another individual user on the system regardless of what talkgroup either unit is in. The call shall allow an individual to alert another user with a distinctive tone and their individual ID/alias (on display radios only). The alert shall be accomplished over the signaling (control) channel and should not affect any voice channels on the system. Initial mobile and portable count is 2029 subscribers, depending on how many subscriber units are equipped with these features it could possibly busy out a system. Can the KISD confirm the actual number of subscribers that would require these features? KISD understands that Individual or Private Call will have an impact on system performance. This feature would only be available to a few select users on the system. The Call Alert feature may be used by all 2029 subscriber terminals on the new system. If this feature is limited to a specific number of terminals or you believe it will have a detrimental effect on system performance please state why and at what point the impact would occur. 2.5 System Manager/Information Mangement System 2.5 System Manager/Information Mangement System 4. System Configuration: System Configuration shall enable the control all of the programmable features of the trunking controllers, radio infrastructure, and network components. Diagnostic Management: Diagnostic Management shall allow an operator to view current status and status history of the system, its sub systems or system components. It shall also allow for diagnostics to be performed on the system's network devices. Can the KISD confirm this would exclude the Microwave Equipment, as it is part of the network? Can the KISD clarify the definition of "sub systems or system components" regarding transmitters and receivers? Is the ISD requesting specifications such as receiver sensitivity, etc.? KISD does not require the proposed Radio Management equipment to control the programmable features of the Microwave Equipment. Diagnostic Management shall allow an operator to view current status and status history of system controllers, site controllers, routers, switches, repeaters, UPS, generators, HVAC, tower lighting controllers, shelter alarms etc. KISD understands that diagnostics capability may not be available on all components of the system. Specifications such as receiver sensitivity, etc. shall be provided in other sections of your proposal?

3 3.3 Baseline Coverage Goals Proposers shall use only the repeater sites listed in CSP section 4.1 in their Baseline design. Klein ISD recognizes that there may Can the KISD clarify 3.4 as 3.3 seems to conflict? As the KISD has determined tower site locations, can the KISD will not be providing their initial coverage results. Coverage results will vary greatly between system technologies, individual link budgets, propagation models, antenna selection, be areas within the District boundaries where KISD provide documentation showing their initial proposed antenna height and terrain and LULC modeling data guaranteed In Building coverage may not be achieved. Nonetheless, Proposers shall provide coverage maps which depict the coverage results? KISD has indicated there are areas within the district sets. Proposers should optimize their design to meet the coverage requirements to the greatest extent possible. System design and guaranteed coverage will be taken into account by KISD in the areas where they will guarantee and test to boundaries where desired in-building coverage may not be proposal evaluation process. the 20 db In Building level of coverage, and achieved. Can the ISD verify the "DAQ 3.4 for 95% of its the 10 db In Building level of coverage. test locations" is required for all (54) mandatory buildings? Has the KISD determined and defined where the inbuilding coverage is not achieved? 3.4 Portable Coverage in Mandatory Buildings 4.1 Preferred Communications Sites In building portable radio coverage is required within all the KISD facilities listed in Table 3.4a below. These facilities will be tested separately. Each building at each of these facilities shall have a minimum DAQ 3.4 for 95% of its test locations. Klein ISD has 6 potential new tower site locations. Five of the six sites shall be used as trunked repeater sites in the Proposer s system design Can the KISD provide further details on testing environments within the mandatory buildings? Can the KISD confirm they require a minimum of (5) sites constructed, or may the final site count be dependent on the contractor s design? Baseline Coverage Goal: The baseline coverage goal is to provide reliable head level portable radio coverage inside all the KISD facilities at the campuses listed below in table 3.4a Mandatory Buildings. A DAQ 3.4 for 95% of the test locations" is required to the greatest extent possible for all (54) mandatory buildings? Klein ISD recognizes that there may be areas within the District boundaries where guaranteed In-Building coverage may not be achieved. System design and guaranteed coverage will be taken into account by KISD in the proposal evaluation process. Yes KISD requires the (5) sites identified as repeater sites be used in the proposed primary system design. If proposers have an alternate system design that meets the requirements for guaranteed coverage but uses fewer sites, they may provide an alternate system design solution in addition to the primary design with the 5 sites. Pricing and all other information must be included with the alternate system designs.

Proposers shall provide all costs associated with equipping the system with GPS location capability, along with a complete description of their system, its capabilities, and monitoring point equipment. Can the District provide a list of expected licenses and anticipated coordination fees? Will the contractor be reponsible for all coordination fees related to tribal, NEPA, etc? Can the District confirm if all system users will require GPS location monitoring? The KISD expects licenses to permit operations on either four (12.5 khz) channels per site for a DMR system or eight (6.25kHz) channels per site for an NXDN system. Vendors are also be required to license the proposed microwave system. Coordination Fees will depend on the coordinators used. Yes, the Contractor will be responsible for all coordination fees related to tribal, NEPA, etc. The KISD will initially be implementing GPS location monitoring on the District s school bus fleet and the Maintenance Department s portable radios. The Transportation Department s system deployment will require GPS monitoring of 350 school buses. GPS location monitoring for the Transportation Department is needed at both the north and south Transportation Dispatch Centers. The Maintenance Department will also require location monitoring of 150 portable radios at the Maintenance Office only. All proposed subscriber units should include GPS hardware for future GPS location monitoring.

Proposers shall provide in their proposal a summary table of their analyses, stating whether or not a supplemental coverage method is being proposed for each location and the method being employed (BDA, DAS, etc.) District facilities may exceed 20dB loss. The KISD does not have information on specific building loss values. Vendors are required to make that determination. Vendors were provided the opportunity to visit all the KISD facilities in order to make the necessary assessments. BDAs are an acceptable method of providing supplemental coverage into heavy loss buildings. Coverage maps shall not include any coverage provided by BDAs. Proposers shall provide in their proposal a summary table of their analyses, stating whether or not a supplemental coverage method is being proposed for each location and the method being employed (BDA, DAS, etc.). Proposers shall also provide costs individually for any supplemental coverage methods in their Pricing Proposal.

7 Section 3 - Radio Coverage Requirments Radio Coverage Maps to be Provided Simulcast Time Delay Interference: All coverage maps for simulcast coverage must account for (display) any harmful time delay interference (TDI), AKA delay spread, which may occur in the proposed system configuration if such interference falls within the coverage footprint shown on the map even if it occurs beyond the required coverage contours. This means that forecasted areas of TDI must be clearly shown on the coverage maps in (grey) or be shown as non covered areas. Additionally, a separate TDI map shall be provided solely depicting areas with potential TDI in (grey). The KISD CSP # references simulcast in several sections. Will the District consider a simulcast solution? Yes, the District will consider a simulcast solution. Section 4 - Communications Sites General Question Can the District provide property/boundary surveys of the project sites? Section 4 - Communications Sites General Question Regarding the South Transportation Center site at TX-249: Will access to the radio tower be provided through existing development or through one of the existing but undeveloped driveways on TX-249?
