7 1. INTRODUCTION Th Broward County radio communications systm is a countywid ntwork that srvs most public safty agncis within th County, with th citis of Fort Laudrdal, Hollywood, Coral Springs, and Plantation oprating thir own systms. Motorola manufacturd th systm, which oprats in th 800 MHz frquncy band. Th systm bgan its volution in 1992 as a six-sit, 20-channl SmartNt systm. Sinc thn th systm has rcivd numrous upgrads as additional agncis incrmntally joind th systm, including Drfild, Hollywood, Fort Laudrdal, and Plantation. Th xpansion includd radio sits to add additional covrag and th addition of radio channls to improv capacity. With thos additional agncis, th systm volvd to its currnt stat, which is a 28-channl SmartZon systm with ight transmit-and-rciv sits and two rciv-only sits. In 2012, th County s cntral controllr rachd nd of lif. In ordr to xtnd th lif of th systm, th County ntrd into a las agrmnt with Motorola Solutions to oprat on a hostd mastr sit (HMS) locatd in th company s manufacturing facility in Plantation. Th systm is now facing numrous imminnt nd-of-support dats for critical componnts. Most notably, th sit and prim controllrs ar no longr supportd, and th systm consols and rpatrs will b approaching nd of lif within th nxt thr to fiv yars. Supporting systms, including th microwav backhaul systm, th fir station alrting systm, and th alphanumric paging systm hav all rachd nd of lif as wll. Basd on th numbr of componnts that soon will rach nd of lif and th substantial invstmnt that would b rquird to furthr xtnd th lif of th systm, th County dtrmind that rplacmnt of all four systms is ncssary. Th County hird Mission Critical Partnrs, Inc. (MCP) to assist with th rplacmnt of th radio, microwav, paging, and fir station alrting systms. Spcifically, MCP is taskd with assssing th xisting systm, valuating usr nds for th nw systm, and conducting a comptitiv procurmnt for a nw Projct 25 (P25) systm to rplac th County s xisting radio systm, as wll as its microwav, paging, and fir station alrting systms. MCP has compltd th assssmnt phas of th projct. Th assssmnt dtrmind that thr primary dsign options ar availabl to Broward County: a P25 Phas I systm; a P25 Phas II systm; and a hybrid P25 Phas I and Phas II systm. Basd on th strngths, waknsss, and cost stimats associatd with ach option, th County lctd to procd with th P25 Phas II option. This rport dscribs th functional systm dsign associatd with a Phas II solution. Th information containd within this rport will hlp to furthr rfin th cost stimats idntifid in th assssmnt and provid th information ncssary to support a procurmnt of th nw systm. Whil this rport idntifis spcifics rgarding potntial radio sit locations and layouts, th ultimat goal is to dfin functional rquirmnts. Functional rquirmnts rquir vndors to guarant how a systm prforms, allowing thm to tak crativ librtis rgarding how thy will achiv th functional rquirmnts. This placs th onus for systm prformanc on th quipmnt vndors. Mission Critical Partnrs 5

8 2. METHODOLOGY This sction provids a dscription of MCP s approach for th functional dsign of th various Broward County communications systms. CANDIDATE SITE SELECTION MCP and Broward County staff collaboratd to idntify altrnat radio sits to xpand radio covrag within th nw systm dsign, in ordr to achiv th covrag rquirmnts idntifid by systm usrs. Candidat radio sits idntifid ar a combination of nw raw-land sits that would b ownd by th County, in addition to xisting radio towr sits ownd by othr ntitis that would b lasd. Radio towr locations wr idntifid taking into account, in larg masur, aras within th xisting systm dsign that rciv insufficint covrag givn currnt usr nds. Within ach ara, MCP valuatd county-ownd proprtis that potntially could b utilizd to construct nw towr sits without rquiring land-las or land-purchas agrmnts. Whn proprtis wr idntifid as having sufficint spac to accommodat a nw towr, radio covrag was validatd using propagation modling. For aras whr nw towr sit construction was not fasibl, MCP valuatd xisting radio structurs ownd by othr ntitis that potntially could b lasd by Broward County. Towr spac was prliminarily valuatd using imags from Googl Earth Strt Viw and thn validatd with a sit visit. Covrag for ths locations was valuatd to nsur that th radio sits will provid th dsird covrag improvmnts. A priority list of radio sits was dvlopd basd on th combination of xisting sits, nw raw-land sits, and lasd sits. RADIO PROPAGATION MODELING MCP prformd radio propagation modling utilizing EDX SignalPro softwar. Link budgts wr compltd with paramtrs utilizing critria rcommndd by th Tlcommunications Industry Association (TIA) TSB-88 standard. Ths link budgts provid th signal strngth lvls to which th systm must b dsignd, in ordr to provid th dsird lvls of in-building covrag. Using th radio sits idntifid through th candidat sit slction procss, MCP dvlopd propagation studis. Various itrations of propagation studis wr conductd using altrnat radio sits until an optimal sit configuration was idntifid. MCP has providd propagation studis dmonstrating mobil, portabl outdoor, and portabl in-building covrag lvls. COVERAGE REQUIREMENTS Basd on th covrag lvls idntifid through propagation modling, MCP idntifid th quivalnt functional rquirmnts that will b providd to systm vndors within th rqust for proposal (RFP) spcifications. Ths functional rquirmnts dictat a rquird lvl of covrag (mobil, outdoor portabl, and in-building with attnuation) to which vndors must dvlop accptabl dsigns. To account for th fact that an quivalnt lvl of covrag is not rquird throughout th county, MCP Mission Critical Partnrs 6

9 dvlopd boundary fils outlining th portions of th county that will hav diffrnt in-building covrag rquirmnts. Aras with a mobil covrag rquirmnt ar dsignd for rliabl communications to vhicls and srvic boats quippd with mobil radios. Aras with an outdoor portabl rquirmnt ar dsignd for rliabl communications to usrs oprating outsid any structurs. Aras with an indoor portabl covrag rquirmnt ar dsignd for rliabl communications within buildings of a spcific attnuation lvl. Bcaus vry building rsults in diffrnt signal losss basd on th building construction, numbr of floors, and th usrs location within th building, covrag dsigns ar basd on an avrag. Th highr th in-building attnuation lvl covrag rquirmnt (.g., portabl covrag in 20 db buildings), th gratr lvl of systm-wid covrag. Whil an nhancd covrag rquirmnt will incras th liklihood of buildings bing covrd, thr is no guarant that a spcific building will b covrd. Covrag can b nhancd in spcific buildings through th propr implmntation of bi-dirctional amplifirs (BDAs). MICROWAVE DESIGN Using th complt list of radio sits idntifid to mt covrag nds, MCP dvlopd a prliminary microwav dsign to dtrmin th liklihood of achiving a fully rdundant loop-protctd ntwork. MCP compltd microwav path studis to dtrmin if a rliabl microwav path can b achivd btwn two radio sits using assumd hights for potntial obstructions, such as trs or buildings. Microwav paths showing claranc of trrain and assumd obstructions wr idntifid as fasibl. Microwav paths claring trrain but not claring assumd obstructions wr idntifid as marginal. Microwav paths failing to clar trrain wr idntifid as unfasibl. All microwav paths validatd through studis will nd to b confirmd by physical path survys during th implmntation phas, in ordr to validat th actual hight of obstructions along ach path. TOWER LOADING STUDIES For ach radio sit, MCP idntifid th rquird numbr of antnnas and thir various locations on th structur. Basd on ths prliminary loading hights, MCP subcontractd with Paul J. Ford & Company to conduct crtifid towr structural studis to dtrmin if th towrs will handl th load of additional antnnas within thir currnt configurations. SHELTER SPACE REQUIREMENTS Basd on th amount of spac rquird for th quipmnt at ach location, MCP idntifid prliminary spac rquirmnts. For ach xisting radio sit, MCP dtrmind if sufficint spac xists for th nw quipmnt and idntifid any rquirmnts for th rlocation of xisting quipmnt. For thos sits whr insufficint spac xists to accommodat both old and nw quipmnt simultanously, MCP idntifid tmporary solutions to hous quipmnt during th transition priod. Mission Critical Partnrs 7

10 CRITICAL INFRASTRUCTURE LOCATIONS For ach of th primary systms (radio, microwav, fir station alrting, and paging), MCP idntifid th locations of critical infrastructur. Locations wr idntifid basd on th scurity and rliability of ach location, as wll as whthr th location could continu to function if th backhaul systm wr to fail. Spac and powr rquirmnts for supporting th quipmnt also wr idntifid at ach location. 3. FUNCTIONAL DESIGN P25 PHASE II 700 MHZ TRUNKING SYSTEM Th P25 Phas II trunking systm will provid th primary communications capabilitis for first rspondrs in Broward County. This sction dtails dsign considrations rlating to th trunking systm, including sit slction, covrag rquirmnts, rdundancy, and critical infrastructur locations. Sit Slction MCP basd its analysis of candidat sits on filling in covrag in aras whr covrag dficincis wr idntifid on th xisting systm. From th fdback rcivd during th assssmnt phas, MCP focusd on xpanding covrag in th following aras: 1. Ovrall improvmnt to in-building covrag throughout th populatd portions of th county 2. Improvd covrag in high-ris buildings 3. Improvd covrag in Drfild Bach 4. Improvd outdoor portabl covrag wst of th Sawgrass Exprss along I-75, and in th Evrglads 5. Improvd covrag in Hollywood to allow convrsion to th County systm Basd on ths critria, MCP idntifid sarch polygons for th idntification of nw radio sits. Th following graphic dpicts th sarch polygons that wr valuatd. Mission Critical Partnrs 8

11 Figur 1 Towr Sit Sarch Polygons Within ths aras, MCP valuatd a combination of raw-land sits and xisting towrs ownd by othr agncis for which Broward County could ntr into a las agrmnt. Whn considring th two altrnativ approachs for towr sit locations, raw-land sits rquir a gratr capital xpns and mor lad tim during construction, but provid a lowr long-trm cost and th potntial for rvnu gnration from othr intrstd partis. MCP s priority was thus focusd on raw-land locations on county-ownd proprtis, although som commrcial proprtis wr considrd as wll. Th following map shows th county-ownd proprtis that fall within th sarch polygons. Mission Critical Partnrs 9

20 MCP nots that in-building covrag critria ar basd on avrags for typical buildings. Th gratr th in-building covrag rquirmnt, th gratr th probability that a building will b covrd. Howvr, du to th larg numbr of variabls within any on spcific building, it is impossibl to guarant covrag within any on structur. Factors that influnc in-building covrag includ placmnt of narby towrs rlativ to th building, building construction, and th numbr of walls th signal must pntrat to rach a usr at any possibl location within a givn building. Basd on ths factors, som buildings may nvr b fully covrd without supplmntal in-building radiating systms. Functional Capacity Rquirmnts Th amount of radio traffic anticipatd on th radio systm during th busist usag tims drivs capacity rquirmnts. In addition to supporting th load of th xisting systm, th nw systm must support sufficint ovrhad to account for usr agncy growth, as wll as incrasd introprability traffic and th potntial for additional agncis to join th systm. Spcifically, thr is a good possibility that both Hollywood and Fort Laudrdal will join th County ntwork. Functional capacity rquirmnts ar dtrmind basd on achiving a dsird Grad of Srvic (GoS), which is a masur of th probability that a usr will b placd in a busy quu bcaus all availabl talk paths ar in us. This probability is dtrmind using Erlang C calculations basd on th likly amount of usr traffic ovr a givn priod of tim.

Fort Laudrdal and Hollywood vntually switch primary oprations to th County systm 3. Thr ar 170 in-county usrs and 500 out-of-county usrs activ on th systm for an introprability vnt 4. Thr is an ovrall growth of 10 prcnt for primary usrs and introprability usrs Critical Infrastructur Locations Th locations of critical infrastructur is crucial to dtrmining th lvl of th rliability that th systm will provid. Basd on th functions of systm componnts, stratgic locations provid improvd capabilitis whn various systm backhaul and quipmnt failurs occur. Th following summarizs th critical infrastructur componnts and th vnts that ar triggrd whn various failurs occur. Systm Controllr Th systm controllr is th cntralizd control cntr for th systm. Audio routs through th systm controllr to coordinat traffic btwn various simulcast clls, multicast sits, and dispatch locations. Th systm controllr also valuats systm accss prmissions to rstrict accss to authorizd systm idntifications (IDs). To improv rliability, MCP has rcommndd co-locatd backup systm controllrs as wll as gographically sparatd systm controllrs, providing four lvls of rdundancy. In th vnt of a failur to th primary controllr, th systm will divrt traffic to a backup controllr. In th vnt connctivity is lost to both controllrs, all traffic within a givn simulcast cll will continu, and th systm will oprat in a backup mod. Th only impact to th dsign for Broward County will b th loss of wid-ara communication btwn usrs oprating on th rmot multicast towr sit in th Evrglads and usrs oprating on th primary simulcast cll, and th loss of primary connctivity to dispatch consols. Dispatchrs will continu to oprat utilizing backup control stations or portabls, just as thy do today. In ordr to minimiz th liklihood of losing dispatch consol connctivity, colocation of th systm controllr at dispatch facilitis is common practic. Simulcast Controllr Th simulcast controllr coordinats all traffic within a givn simulcast cll. Bcaus Broward County primarily will b srvd by a singl simulcast cll, this controllr rprsnts prhaps th most critical lmnt of th Broward County ntwork. MCP s rcommndation includs colocatd and gographically rdundant prim controllrs for th simulcast cll. In th vnt that th primary and rdundant controllrs xprinc a failur, th systm switchs to a third backup mod, rsulting in ach channl oprating as a convntional rpatr. This mod of Mission Critical Partnrs 19

22 opration rsults in a significant impairmnt to systm oprations, thus th high lvl of rdundancy of controllrs and ntwork quipmnt is imprativ to th ovrall rdundancy of th systm. In ordr to minimiz th risk of this scnario, it is a bst practic to co-locat simulcast controllrs with radio sits, thus minimizing th liklihood that a simulcast controllr will los backhaul connctivity to th radio ntwork. Sit Controllr Sit controllrs ar locatd at ach radio towr and consol sit, coordinating sit activitis with th simulcast controllr and systm controllr. Th sit controllr is accompanid by sit routrs and switchs, which provid th Intrnt Protocol (IP) connctivity back to th radio ntwork. Co-locatd rdundant sit controllrs, routrs, and switchs ar rcommndd so that th failur of any on componnt will not rsult in a radio sit failur. If primary and rdundant sit controllrs, routrs, or switchs fail, th radio sit will b disconnctd from th ntwork. This will rsult in a rduction of covrag, maning fild units will hav limitd ability to communicat with ach othr and dispatch within th aras immdiatly surrounding th sit. Givn th sit dnsity, th loss of any on sit will limit in-building covrag within th affctd ara, but still prmit portabl outdoor and mobil covrag. Basd on th facilitis availabl within Broward County, Tabl 8 blow summarizs th rcommndd locations for critical infrastructur. Tabl 8 Rcommndd Critical Infrastructur Locations Critical Infrastructur Location Justification Componnt Systm Controllr Cntral Dispatch Cntral dispatch is a hardnd facility with an quipmnt room to support th controllr. By colocating th systm controllr at cntral dispatch, thr is a gratr liklihood that connctivity to dispatch will not b lost to du to backhaul failur. Du to spac limitations, rconfiguration within th quipmnt room will b ncssary to accommodat additional quipmnt. It is stimatd that 2 to 3 quipmnt racks will b rquird for th systm controllr Backup Systm Controllr Emrgncy Oprations Cntr Th Emrgncy Oprations Cntr is a hardnd facility ratd for a Catgory 5 hurrican, providing a high liklihood that th facility will not b impactd by a major wathr vnt.

23 Critical Infrastructur Componnt Location Justification Simulcast Controllr Cor By locating th simulcast controllr at a radio sit, opration of th co-locatd radio sit will continu vn aftr failur of th backhaul ntwork. Th Cor location is cntrally locatd within th county, and will provid a mobil covrag footprint with continud trunking opration in th vnt of a backhaul failur. Backup Simulcast Prim Controllr Davi Again, by locating th backup prim controllr at a radio sit, opration of th co-locatd radio sit will continu vn aftr failur of th backhaul ntwork. Th Davi sit will b locatd on on of th backup systm sits, and will thrfor hav rdundant Ethrnt connctivity. Dispatch Cntrs Rplacmnt of th dispatch consols is rquird for compatibility with th nw systm. Th procurmnt must includ a on-for-on rplacmnt of ach consol position. Whil th P25 standard dos provid a mchanism for third-party dispatch consols to connct to radio systms manufacturd by othr ntitis, th intrfac costs oftn xcd th potntial cost savings that may b ralizd by provisioning quipmnt from a third-party vndor. Howvr, som P25 systm vndors do not manufactur thir own consol quipmnt; thus, an intrfac btwn such systms and third-party consols is rquird. Gnrally, th fatur sts and capabilitis offrd by P25-compliant consol systms ar consistnt. Th following fatur sts ar idntifid as nds and ar rcommndd for inclusion within th spcifications: Accss to any talkgroup within th systm from any dispatch cntr Unit privat call capability Call alrt (radio pag) Instant rcall rcordr Intrcom btwn positions and cntrs Unit ID and alias Buttons for alrt tons Mission Critical Partnrs 21

With modrn IP-basd radio ntworks, consol systm backroom quipmnt is significantly rducd compard with th currnt circuit-switchd systm. Th consol control quipmnt is limitd to primary and backup sit routrs and switchs, which occupy approximatly on-half of a standard 19-inch quipmnt rack. This quipmnt must b dployd in paralll to th xisting consol systm to allow for a smooth transition. Tabl 9 blow summarizs th numbr of dispatch consols rquird at ach cntr. Tabl 9 Rquird Numbr of Dispatch Consols Dispatch Cntr Dispatch Positions Backup Consoltts North Dispatch (Coconut Crk) Cntral Dispatch (Sunris) South Dispatch (Pmbrok Pins) In addition to th primary trunkd connctivity that will b providd through th microwav ntwork, backup consoltts ar rcommndd to provid a convntional intrfac to th trunking systm in th vnt th systm gos into sit trunking mod which usually occurs whn connctivity is lost btwn th simulcast controllr and th systm controllr or connctivity is lost to th dispatch cntr. MCP rcommnds on consoltt pr dispatch position, with th ability to chang th consoltt channl rmotly from ach consol position. Backup Voic and Data Systm It was dtrmind during th assssmnt phas that a fixd backup systm is a high priority for Broward County. Balancing covrag, cost, and capability, MCP rcommndd a four-sit, svnchannl P25 Phas II 700 MHz systm, offring portabl outdoor covrag and som in-building covrag. MCP rviwd th availabl sits and considring both a covrag and th availabl spac within th xisting quipmnt shltrs dtrmind that th EMS, Coconut Crk, Channl 2, and Davi sits provid th bst availabl locations. To maximiz th liklihood that th backup systm will rmain oprational vn in th vnt of a failur to th primary ntwork, MCP idntifid th following rquirmnts: Mission Critical Partnrs 22

25 1. Rdundant Ethrnt backhaul in addition to microwav primary connctivity 2. Primary cntralizd controllr locatd at a radio sit not usd on th primary ntwork 3. Systm opration not dpndnt on dactivation of th primary systm, which would rquir sparat frquncis and systm rsourcs 4. Expansion of th Rgional Domstic Scurity Task Forc (RDSTF) introprability projct 5. Dispatch backup accss via control stations In addition to ths primary goals, MCP idntifid th opportunity to lvrag th trunkd backup systm for data applications. Data applications occupy idl voic paths, but los systm accss whn all availabl voic paths ar activ. By lvraging th backup systm for data applications, thr will b a high liklihood that th ncssary rsourcs always will b availabl for data usag. Usr agncis indicatd that it would b dsirabl to hav th following data applications lvrag th backup systm: 1. GPS/Automatic Vhicl Location (AVL) 2. Ovr-th-air Programming (OTAP) 3. Ovr-th-air Rkying (OTAR) In addition to th trunkd backup systm, a convntional ovrlay was idntifid that rquirs no widara dpndncis for opration. It was dtrmind that a four-sit ntwork with two convntional channls locatd at ach of th EMS, Coconut Crk, Channl 2, and Davi locations would provid accptabl covrag. Such a systm would oprat on th 700 MHz introprability channls, prsrving gnral-us channls for th primary trunkd systms. Opration would b in P25 convntional mod in complianc with FCC and Stat of Florida rquirmnts for 700 MHz introprability channl usag. To support communications at any location that may xprinc a failur, a mobil communications platform was idntifid as a solution that could b dployd to any undfind locations. Th following rquirmnts hav bn idntifid for th mobil communications platform: 1. Trailr with sufficint spac to accommodat all idntifid quipmnt foot-minimum xtndibl mast with prmanntly mountd antnnas 3. Total of 10 rack-mountd control station radios oprating on various rgional systms, introprability channls, and public safty frquncy bands intrfacd to a graphical usr intrfac (GUI)-basd gatway 4.

26 ISSI/CSSI Th Intr-RF Subsystm Intrfac (ISSI) is a P25 standard fatur that allows for th intrconnction of P25 systm infrastructurs, allowing talkgroup traffic to b carrid across systms. Th ISSI was idntifid as a bnficial fatur that could b utilizd to nhanc introprability within Broward County. Spcifically, MCP has idntifid th following systms to b prioritizd for ISSI connctions: 1. Motorola HMS srvicing th Fort Laudrdal, Coral Springs, and Plantation systms 2. Miami-Dad County 3. Palm Bach County 4. Collir County ISSI connctions rquir a combination of infrastructur and softwar to b implmntd by ach of th intrconnctd agncis. Thrfor, coordination will nd to occur btwn th partnr agncis to obtain thir commitmnts for purchasing th rquird componnts for thir half of th connction. Th Consol Subsystm Intrfac (CSSI) allows for th intrconnction of P25-compliant dispatch consols with othr systms, ithr from th sam or diffring manufacturrs. CSSI connctions allow P25-compliant dispatch consols to connct to multipl P25 systm controllrs, prmitting talkgroup accss without th us of convntional intrfacs. CSSI is ssntial to nsuring that Broward County has dirct accss to Fort Laudrdal talkgroups without rquiring control stations with convntional intrfacs. CSSI connctions to othr systms also will nabl consol accss to any numbr of appropriatd talkgroups. CSSI connctivity is rcommndd for th following systms: 1.
