l.lVEl~ORE :1':<i6.. f".~' .'., Wireless Communications Consulting RFP I RFQ #6001 MACRO ,~ Task 2: Review and Analysis of Alternative Designs Activities associated with this Task are: Activity 2.a - Review of Alternative Voice Systems Designs Activity 2.b - Consideration of Wireless Data Activity 2.c " Radio Coverage Prediction Studies Activity 2.d - Present System Design Options , Activity 2.e . Preliminary System and Site Recommendations Activity 2.f . Field Coverage Testing Activity 2.g . Report Development The purpose of this Task is to present various system design alternatives and option~ targeted at addressing system deficiencies and/or user needs and requirements identified in the previous Task. This will include continued use of trunked technology, digital technology (APCO Project 25, other digital voice radio platforms), new or additional radio sites, continued use of BDAs, etc. These will be narrowed down to the most appropriate alternatives and options for further consideration. Voice and data networks are converging - to the point where a single network can support both voice and data messaging. There are several wireless systems on the market supporting voice and data _ usually through the use of Voice-over-Internet-Protocol (VoIP). We will consider these options as we focus on our primary objective, which is the voice radio system. Macro will consider up to three conceptual designs - these will be presented with a pro/con analysis and estimated budgetary cost ranges. Impacts on interoperability (positive or negative) will also be addressed for each alternative. Normally, our alternative development efforts begin with a "Baseline Alternative," such as simple replacement with like-kind equipment, with a provision for various "add/delete" options _ such as the addition of new repeater sites, addition of channels (if feasible), upgrade to simulcast technology, digital Project 25 conversion, etc. We will then develop two other alternatives for consideration, with similar add/delete options if appropriate. One likely alternative would consider joint-use of, or interface to, the Alameda County trunked radio system.2 For example, possible configurations could include: ~ Use of the County system as-is (discontinue use of Doolin) ~ Expansion of the County system to serve both Cities (where Countv would own the "system") ,.. Expansion of the County system to serve both Cities (where the Cities would own the additional tower site equipment) ~ Stand-alone radio system, compatible with the County system (the "Status Quo Alternative") 2 Which may later become the Regional Communications System (RCS) comprised of both Alameda and Contra Costa counties. This is currently in the planning stages so limited information may be available. Proposal No. 4763 Copyright@2006 Macro Corporation Communications Services Section 3 - Questionnaire Responses Page 5
