IlVEl~tCJRr ~)~.J.~.". Wireless Communications Consulting RFP I RFQ #6001 MACRO lU- We note that these possible alternatives are independent of the 9-1-1 radio dispatching function _ in other words, each City could continue to maintain its own dispatch center under each of these Alternatives _ or not. 3 However, we will consider how existing or new dispatch console systems would integrate into each alternative. Macro will characterize the radio coverage provided by each alternative, by producing computer-based coverage prediction maps. These will be helpful in selecting an appropriate alternative system design and technology. We note that it is statistically impossible to provide for 100% coverage inside each building and for all outdoor areas within each City, 100% of the time. While we have not quoted to identify and characterize a coverage solution for each specific type of building, our goal is to design for indoor coverage to the extent achievable given the limits of the proposed scope of work and the normal financial limits of the Cities to construct a robust and reliable network. For the purposes of coverage design for any new system, we have anticipated that the Cities will require approximately the same number of repeater tower and BDA sites as in use today - plus 20% additional to solve any identified coverage deficiencies. Based on the findings from the airtime logging in the previous Task, it may be appropriate to consider expanding the capacity of the radio system. This may require acquisition of additional radio channels, depending on the technology. 4 We will address channel availability in the new 700 MHz and 800 MHz radio bands as required. The culmination of this task will be the publication of the Preliminary System and Site Recommendations Report. This report would specifically identify the most appropriate alternative system design, as well as identify the preferred arrangement of radio sites. A draft report will be issued initially for City review and comment. We will then finalize this document and provide it in electronic form (Adobe PDF) for ease of distribution, as well as in printed form (4 copies). Deliverable #2: Preliminary System and Site RecommendatiollS Report Field coverage testing is the most appropriate method to assess "real-world" coverage provided by a radio tower or BDA site. Macro has quoted to perform drive tests - using our vehicle and our automated GPS-based testing gear - over the entire two-city area, and slightly beyond.' This will measure signal strengths from the recommended site or sites to verify adequate signal strength and quality of service (QoS). A separate deliverable will be provided which presents a geographical picture of our measurement results, as well as our comments and recommendations. We have provided a sample of similar measurement results in this proposal (see index tab marked "Sample Reports"). Deliverable #3: Field Coverage Test Results and Recommendation J The City's RFPIRFQ did not request consideration of dispatch consolidation, and we have not included this in our proposed scope of work. 4 It is not known whether applications for new channels will be required, Macro will quote separately to provide this service if requested. 5 Testing requires that transmitters (i,e., repeaters or BDAs) exist at the tower sites being tested, If a new site is to be tested, we recommend that the County. or other vendor, temporarily install a test transmitter for the duration of these tests (1-2 days). Costs for this service has not been included in our proposal. Proposal No. 4763 Copyright@2oo6 Macro Corporation Communications Services Section 3 - Questionnaire Responses Page 6
