19 In building antennas Low Profile Cell MIMO Antenna Top Hat Great performance Low Ugly Factor Aesthetically Pleasing Lower performance above 1900 Low Profile VHF Aesthetically Pleasing Large Footprint Above Ceiling Mount Good Performance Large Form Factor

20 EMERGENCY RESPONDER RADIO COVERAGE DAS DESIGN CRITERA International Fire Code NFPA 72 NFPA 1221 RSSI

21 ERRCS Requirements Code Section Technical Requirement A minimum signal strength of 95dBm is required to be received within the building A minimum signal strength of 95dBm is required to be received at the PSN radio tower All signal boosters must be FCC certified The system shall be supported with 24 hours of Secondary power.

22 ERRCS Requirements Code Section Technical Requirement All signal boosters shall be installed in NEMA 4 Enclosures All battery systems shall be installed in NEMA 4 Enclosures The signal booster and battery systems shall be supervised an monitored by a supervisory service.

23 CASE STUDY 1 SIMPLE PROJECT La Salle School of Business Location: Size: System: Code: Equipment: Philadelphia 87,000SF 800MHz ERRCS 2012 IFC BDA Only 24 Hour UPS

24 ALL EQUIPMENT IN A SINGLE RACK La Salle RELAY PANEL AND POWER SUPPLY AC UNIT NEMA 4 ENCLOSURE

25 La Salle WIRELESS MODEM BIDIRECTIONAL AMPLIFIER UPS AND BATTERIES ALL EQUIPMENT IN A SINGLE RACK

26 FA MONITOR MODULES La Salle POWER SUPPLY RELAY PANEL ALARMING COMPONENTS

27 CASE STUDY 2 large project Location: Size: System: Trinity Phase 3 San Francisco 997,930 SF 700/800MHz ERRCS Code: 2010 CFC/2009 NFPA 5000 Equipment: BDA + 12 PSN RRU 12 Hour UPS Centralized DC Power

28 ROOM LAYOUT HEAD END TWO NEMA 4 ENCLOSURES WITH AC COMPRESSORS WALL MOUNT BIDIRECTIONAL AMPLIFIER

29 TRINITY PHASE 3 ACTUAL CABINET LAYOUT SECOND AC UNIT TUCKED BACK HERE AC COMPRESSOR FOR THERMAL MANAGEMENT OF EQUIPMENT IN ENCLOSURE TWO NEMA 4 CABINETS REQUIRE FRONT AND REAR ACCESS

30 TRINITY UPS AND DC POWER SUPPLY DC POWER SUPPLY FOR REMOTES UPS CONTROLLER STACK O BATTERIES

31 TRINITY BACKSIDE OF CABINET BATTERY PACKS DAISY CHAIN AT THE BACK

32 TRINITY WIRELESS MODEM FOR REMOTE ACCESS TO SYSTEM

33 FIBER TRANSCIEVER DC POWER SUPPLY FOR REMOTES UPS CONTROLLER STACK O BATTERIES TRINITY SECOND RACK FIBER TRANCIEVER DC POWER SUPPLY AND UPS

34 TRINITY FIBER TRANSCIEVER & SECOND DC POWER SUPPLY (SECOND RACK)

35 TRINITY ALTRONIX POWER SUPPLY TO SERVE RELAY PANEL FOR ALARMING BACK UP BATTERIES FOR POWER SUPPLY

36 TRINITY RELAY PANEL TO SUPPORT NFPA REQUIRED ALARM OUTPUTS WE PROVIDE THIS RELAY PANEL FOR EVERY ERRCS PROJECT THAT ENFORCES NFPA 72

37 CELLULAR COVERAGE SYSTEMS PLANNING

38 CELLULAR DAS DESIGN CRITERA RSCP (RECEIVED SIGNAL CONTROL POWER 3G) RSRP (RECEIVED SIGNAL REFERENCE POWER LTE) DOMINANCE

39 SAMPLE CARRIER REQUIREMENTS SPRINT RSRP =RECEIVED SIGNAL REFERENCE POWER= 98dBm DOMINANCE 6dB STRONGER THAN MACRO RSRP COVERAGE AREA IS 90% OF FLOOR AREA

40 SMALL BUILDING DAS ROOM BASE STATIONS VERY UNLIKELY IN THIS SMALL BUILDING

41 TWO SMALL CELLS MINIMAL SPACE, MINIMAL POWER, NETWORK BACKHAUL VIA UTP CABLE.

42 MEDIUM BUILDING DAS ROOM

43 Location: Size: Systems: CASE STUDY AUBURN MULTICARE 330,000 SF 800MHz ERRCS, 900 MHZ PAGING, UHF RADIO, AT&T, VZW, SPRINT (No T MO)
