  8. Recap of Survey Highlights Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  9. Survey: Non-Trunked Systems • BDA Counts: • Waukesha County: approx 42 (known) 800MHz BDAs • Milwaukee County: approx31 (known) 800MHz BDAs • Other Systems: • Waukesha County Siren Control – mainly on VHF but one municipality uses an 800MHz trunked talkgroup • Waukesha County Knox Boxes – mainly through 800MHz trunked talkgroups • Milwaukee and Waukesha County – EMS data primarily through non-trunked systems • Waukesha County – 3 - 800MHz simplex channels for tactical comms • Milwaukee County – Single-site P25 system at Channel 58 • Milwaukee County – North Shore Fire uses Mobex DVRS to relay 800MHz (trunked system) to on-scene VHF tactical comms • Implications: • Replacement of BDA’s would be costly if different band were selected • New system must include some method of passing “analog” signals of siren alerts and Knox Box tones Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  17. COVERAGE DISCLAIMER • The following maps are meant to examine trade-offs and alternatives, they are not based on any detailed design nor are they to be taken as any implication of final-system performance Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  19. Coverage Map Guide (II) Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  20. Coverage Map Guide (III) Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  21. Coverage Maps • Note: Map “W7” is incorrectly labeled “4.3.1” Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  22. Coverage Map Implications • For Waukesha County • The transition from analog to Project 25 Phase I technologies in the Waukesha County portion of a “Two Connected Zones” concept would improve countywide coverage • The impact of changing Waukesha County’s coverage specification to include 15dB, not 12dB buildings, does not significantly affect delivered coverage • The impact of some users in Waukesha Counting transmitting with their portable radio at their hip (not head) does not significantly affect delivered coverage (this is likely due to the fact that the coverage gains due to the increased elevations of “public safety microphones” (which place the antenna at the shoulder/head level) can be nearly entirely offset by the loss associated with the cable used to connect the “public safety microphone” to the portable radio) • The addition of a site at Vernon Town Hall does significantly improve coverage in the area around Mukwonago and in the southeast corner of the County • The addition of the site at Merton Fire Department does significantly improve coverage in the area around Merton and Sussex and along the north edge of the County • The relocation of the site from its current location in Menomonee Falls to Tower Hill has little positive or negative affect Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  23. Coverage Map Implications • For Milwaukee County • The transition from analog to Project 25 Phase I technologies in the Milwaukee County portion of a “Two Connected Zones” concept would have little impact on countywide coverage • The impact of changing Milwaukee County’s coverage specification to include 20dB, not 15dB buildings, does not significantly affect delivered coverage, however, such a change is not recommended • The relocation of the site at Lakeshore Towers to the 440th would likely cause further problems in talk-out coverage along southern portions of Milwaukee County’s lakeshore • The relocation of the site at Brown Deer Park to the Bayside Police Department would improve coverage along the northern portions of Milwaukee County’s lakeshore but it would cause problems with talk-out coverage in areas North of Greater Milwaukee International Airport (GMIA) Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  24. Coverage Map Implications • For Both Counties • The transition from analog to Project 25 Phase II technologies would cause significant coverage problems in both Waukesha and Milwaukee Counties (Note: the maps included in Appendix C do not include diversity receivers and antennas at infrastructure sites, a practice that is recommended by some vendors) • The coverage of the “One Massive Simulcast” system concept, using existing sites, provides good coverage across both Counties, however, the relocation of the site at Brookfield to the site at Vernon Town Hall improved coverage near Mukwonago but introduced coverage problems West of Menomonee Falls Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  25. High-Level Comparison of Alternatives (Tech Issues)

  26. High-Level Comparison of Alternatives (Non-Tech Issues) Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  27. Non-Trunked System Alternatives • To meet the needs of siren alerting, Knox Box, and any other (known or unknown) analog-formatted signaling, a set of 800MHz conventional, analog, simulcast systems should be deployed • Could reuse existing equipment • Could be used as back-up to trunked system • For existing trunked systems and consoles, some vendors offer legacy interfaces which could be used to assist in cut-over Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  28. Budgetary Cost Analysis • Capital Cost • For “1 Massive Simulcast”: • For Waukesha County: $23,536,800 • For Milwaukee County: $27,437,300 • Total: $50,974,100 • For “2 Connected Zones”: • For Waukesha County: $22,475,500 • For Milwaukee County: $26,998,400 • Total: $49,463,900 • Operations/Maintenance Costs • For “1 Massive Simulcast”: • For Waukesha County: Approx $600k/year • For Milwaukee County: Approx$780k/year • For “2 Connected Zones”: • For Waukesha County: Approx $625k/year • For Milwaukee County: Approx$875k/year Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  29. High Level Deployment Plan • Waukesha County has funds to for ‘all-at-once’ deployment • Detailed implementation and cutover plan still TBD • Milwaukee County’s funding requires 5-year phased plan Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio

  30. Impact to Existing Equipment • Records of Waukesha County’s existing fleet of approximately 4,500 user radios show that approximately 2,700 can be reconfigured by software (“flashed”) to support P25 capabilities. • Milwaukee County records show that of the approximately 4,150 total subscriber radios currently in use on the system, an estimated 1,000 could be reconfigured by software (“flashed”) to support P25 capabilities. • For both Counties, those radios than cannot be reconfigured by software to support P25 would need to be replaced. • Other reuse possibilities: • Power equipment at sites • Existing trunked simulcast equipment as conventional, analog overlay (for analog signals) Waukesha & Milwaukee Counties: Consulting Services: Trunked Radio
