Authorize the Consultant to proceed with the allocation of a new radio frequency for the Police Department. 2. Approve and adopt Resolution No. 7Q /,C:, , authorizing the purchase of communications equipment with an intra-departmental transfer of funds from the Police Department fiscal 82/83 budget. ITEM EXPLANATION During 1982 Staff was directed by Council to evaluate radio communications problems in the Police Department. With the approval of the City Manager, the Police Chief engaged a professional communications consulting firm to prepare an indepth study of the Police Department radio system. The firm, "The Richter Group" was selected to conduct the study at a cost of $3,327., which was funded from existing Police Department operating funds. The dei;a.iled recommendations are set forth in the attached report and memorandum. 'l'he City l:ianager and Police Chief have reviewed the report and recommend the City· approve expenditure of monies from the Police Department budget in order to implement the recommendations. The recommendations propose the allocation of a new police ~'Sl.dio frequency; the change of the present "Simplex" system to a mobile- relay operation, utilizing the present frequency as a back-up tactical frequency, and the purchase of the following communications equipment to accomplish the changes: (1) Mobile relay $6,500 Installation, antenna and cable (2) Satellite receivers $1,800 Installation, antenna and cable (2) Voter -Comparators $5,200 (2) T/R modules for console $2,800 Convert mobile and HT radios $7,000 (2) Call Director console panels $3,600 (10) Dispatch headsets $2,000 (1) Computor printer sound cover $ 400 (1) Battery pack for radio logging $ 250 recorder (2) Call Counters for each Call Director $ '150 $30,000 AGENDA BILL -Police Page 2 The recommended changes would be a one-1:ime changeover that will alleviate present system deficiencies and will at the same time fulfill operational requirements of the proposed system in the planned Public Safety Center. FISCAL IMPACT The proposed recommendations would require the expenditure of approximately $30,000 to purchase the nP. assary communications equipment to accomplish the radio system changeover and improve- ments. After thorough review of its present operating budget, Police Department Staff are recommending an intra-departmental transfer of funds to accomplish the recommendations. The fund transfer is possible due to salary savings and unanticipated savings in several maintenance and operations accounts. The Finance Director has reviewed the proposed fund transfer and concurs with the expenditure. ALTERNATIVES Without approval the Police Department would attempt to implE.iment the recommen1ations through the FY 83/84 budget, if conditions permit. If recommendations a:re not implemented at this time, they wlll be requested for development in the proposed Public Safety Center. EXHIBITS l. 2. 3. 4. /na Consultant's report, dated April 1, 1983.

IN'fROCUCTION This report to the City of Carlsbad describes an engineering consulting stuay concerning two radio problems being experience by the Carlsbad Police Department (CPD). Alternative solutions to these problems are suggested and a recommendation is made. The tw o pr o b 1 em s a r e : C l ) s e r i o u s a n a , a t t i me s , destructive radio interference on the CPD primary dispatch channel from the City of South Pasadena; and (2) dead spots and areas of poo~ coverage within the city of Carlsbad, particularly involving handheld radios. Although these two problems are separate ana distinct, there is some commonality in the possible solutions; the study has therefore taken this into account in the basic investigation as well as i:1 the alternatives c1evelopment. The fellowing sections ot chis report describe the funda- mentals of the problems which created the need for the study; explain the study activities used to understand the cau~es for the problems; explore solutions; present conceptual solutions, with accompanying descriptions ano pricing estimates; and, finally, provide the city with a recommendation. The Richter Group has appreciated the opportunity to work with the city staff ana to begin to develop a relationship. The city staff is to be complimentecl on its willing and businesslike approach to understanding and seeking solutions for the cc~~unications problem. The staff has been most helpful in assisting with field measurements and coverage surveys, and this cooperation is gratefully acknowledged. F.-G 252/1 1 2. srATEM.....'C'NT OF TaE PROBLEM The CPD has had two long-term, serious problems ,,ssociated with its radio system. these problems, but, Several attempts have been made to solve to aate, real relief has not been experienced. This consulting study was commissionea to determine the true nature of these problems and the reasons for them, and to present solutions ana a recorrmendation to the city. The first problera has been one of serious interference occuring on the CPD's primary dispatch frequency, a.,a the second problem involves inadequate radio coverage throughout the cit~{. 2.1 INTERFERENCE The dispatch frequency 058.835 HHz} is a channel that has actually been allocated to the local-government service, and is not a police frequency, per se. Police frequencies receive a great deal more ~rotection than do those in local-government service. '!'here are several other local-901.1ernment users on this fr€<.tuency (used by CPD for aispatching). One of the co-channel entities is the City cf South Pasadena local-government (Public Works} operation. Although one would think that South __ Pasadena is sufficently far from Carlsbad so as to have significant isola- ticm between radio syst:ems, this is not the case and quite strong signals reach the CPD base station, occasionally strong enough to block out CPD mobiles and handheld radios. At the minimum, slgnificant nuisance interference is heard"by the dispatchers. In its extreme, as was j~st mentioned, the trans- missions from CPD police cars are actually overridden ana communication blocked. RG 252/2 2 / ----- _. ........ -----,,.,,-1 ~ --------- R?,D!O COVERAGE The city is.rather long, extending north to south, and is broken up with ridges and rolling hills; apparently, no one radio site will provide total coverage of the city. The problem is especially severe for handheld radios {which have small, inef- fective an_tennas and low power) operating from the northern and southern extremes of the city where terrain and geographical blockages occur. The CPD base station is located at Ellery Reservoir, which provides good coverage of the downtown area and the east-west portions of the city. There were claims that officers are actually out of contact with their dispatcher in certain portions of the city. This ~nd the interference problem r.,entioned above have been the subject of considerable discussion and compiaints by field officers. RG 252/2 3 the problem, all that remained was to develop a solution. 3.2 COVERAGE The seconc problem, the purported radio coverage deficien- throughout the city, requirea more investigation. The first step was to have Richter Group staff spend time riding in the Jehicles during routine patrol operations. This provided 3oi:,e familiarity with the city, with its radio system, and with CPD op~rations. The second step was to ask the patrol force to d~cument coverage deficiencies, as they occurred. Forms and city Raps were distributed for this purpose, and a number of an~~ers were received. The deficient areas did not offer a significant surprise; the worst occurred in the La Costa area (south extreme of the city) when handheld radios were used. There also was an occasional complaint about mobile-radio coverage in this area. A city map was then marked with the boundaries of the deficient area, and plans were developed for conduc-ting a survey of actual field strength and coverage. The coverage survey·was made on March 8, 1983. 'l'he tech- nigue was to calibrate and use actual CPD radio eguipmer,t. The RG 252/3 .~~.~ ~' }I,,'. '. t ·: .. , f •. - ·•~ci~er ana base station at Ellery Reservoir were calibrated .. r J .::. ~cter was temporarily installed to measure incoming signal ~tc~~sth through the actual antenna, transmission line, and =~ceive: used for CPD dispatch. A mobile radio and patrol car ~ ~=~ aimilarly calibrated (a temporary meter-installation, cali- !'r~ti:d in terms of signal strength) and used as the field ~~asurement tools. During the field test, a person sat at ~ll~ry Reservoir taking readings at each one of the check FOintz; the operator of the patrol car similarly recorded all reacings. rr. addition to the tests made on the CPD dispatch i ~1:.,;.uency, tests were made on the Carlsbad Pire Department ( CFD) disp,1tch f reguency at the same time and in the same vehicle. It w.:is felt that one possible problem for coverage deficiency was the location of the CPD base station (Ellery Reservoir). Discussions had established the fact that the CFD system ~fpdrently had had fewer coverage deficiencies {primarily a ,.,oh.!..le system, with minimal handheld use); the CPD base station w~3 located at Squires Darn. Since the CFD radio system operated in the same general frequency region as the CPD system, it was decided to obtain coverage measurements from the Squires Dam site, as well as f row the Ellery Reservoir, and so the CFD radio· sy~tem was used to accomplish this. 1'he receiver in the CFD base station equipment at Sgui res Dam had a temporary strength meter installed and was calibrated with the RG frequency standard. A CFD mobile radio was borrowed from the CPD and temporarily installed in the patrol car, using a magn€tic-mount antenna on the roof cf the vehicle. •rhis receiver also had a temporary signal-sirength meter installed anj was calibrated with the RG frequency standard for the measurement process.

A number of stops were mace and signal-strength readings were obtained by means of the two meters in the patrol car, the meter at Squires Dam, and the meter at Ellery Reservoir. This data was recorded on field survey forms and was subjected to engineering analysis. The results are shown in the following two figures. Figure 3-1 depicts the coverage measured on the CPD frequency, using Ellery Reservoir as the transmit site. Figure 3-2 represents the coverage measured on the CFD frequency using the Squires Darn site. It will be noted that areas of poor coverage were confirmed and, also, that neither Squires Dam nor Ellery Reservoir alone provides citywide coverage. It was also noted that the talk-in leg of the communications was the one exhibifing significant deficiencies; and that the talk-out problem (base to mobile to handheld) was less severe. This condition is common. RG 252/3 6 t' {• t'.' ft ii:' ~ -~-.. ~ ~ ,t ., \\ ' .::; :· 11,,. i: i \ I ~ f ti ;,, ', ' ~'. r i;i' ,., r ~-f,· ~~ ~ j. ., ~-I·• i t"I' j. ,,.

ALTF..RNATIVES AND SOLUTIONS 4 • l INTERFERENCE The only practical solution is to change to a frequency that does not experience severe interference. There are some technical steps that could be taken in Soutr. Pasadena to reduce the fu"ount of radio power that is directed toward Carlsbad, but the city of South Pasadena was not particularly anxious to revamp their system. Even if South Pasadena would be willing to install a new antenna with a directional null toward Carlsbad, there is no good assurance that interference would not come from some other source since the frequency is a local-governmen~ fre~uency and is not subject to the same protection standards employed for police frequencies. The obvious, clean solution is to find a new frequency (much easier to say than to do) for CPD dispatch. A listing of forty frequencies was preparea for consideration. The Southern California Frequency Coordination listing is maintained on the Richter Group computer. There is no unused police frequency in California; the process of selection, therefore, involves ex~~ining all candidate frequencies for interference potential, ranking these, and then examining them in a~tail. It is usually necensary to perform actual field tests to convince a potential co-channel user that the new system can be operated without oestructive or serious nuisance interference. This step is necessary in Carlsbad. Since the only viable solution is a new frequency, a further recommendation is made to the city t~?t t~o frEquencies be obtained so that the CPD dispatch system can operate in the mobile-relay (repeater) mode. A mobile-relay system pro•,ides the capability of talking between units anywhere in thi: city. With the present single frequency ( simplex) system, communica- F:G 252/ 4 9 I i I I ; I tions between units take place only as far as their radios can transmit directly; this is a fairly short distance for handheld units, with their weak power and inefficient antennas. A mobile-relay system usually operates on a hilltop and involves a repeater arrangement; a signal is received from the handhelos (usually quite effectively at an elevated site) and is then rebroadcast by the higher-powered transmitter from this same site. This provides a very effective coverage of the area. A mob~le~relay ~ystem is pref~rable to simplex for police use because any unit within the coverage area can talk with any other unit~ everyone hears everyone else and there is much better knowledge of what is happening on a moment-by-moment basis. The present arrangement means that an officer with a mobile radio in Le1 Costa, unable to hear an off ;.cer at the mall calling dispatch over a handheld radio, might transmit at the sa.'Tle time, effectively destroying the {perhaps crucial) roessnge that the officer at the mall is trying to transmit. With a mobile-relay system, everyone can hear the handhela, eliminating this type of contention. The cost difference between a mobile-relay system and a simplex system is not significant, except for the increased difficulty of obtaining two frequencies that are spaced properly for mobile-relay operation. More details _about how this might be implemented are contained in the · r.ecormnendations section. 4.2 COVERAGE A whole spectrum of possibilities exists for the solution to the coverage-deficiency problems. First, it appears most likely tnat no single site location will provide effective coverage for the entire city. Multiple receivers Cana perhaps transmitt.ers) will be required for any solution. RG 252/4 -----------------~ ------------ The customary solution to the talk-in problem is to locate one or more satellite receivers in poor-coverage areas and bring th~ir signal< s) back in over leased telephone line ( s). To use a satellite receiver effectively requires an additional piece of equipment, a comparator-voter. Having two loudspeakers, each connected to a different receiver Cone with a good signal, one with a poor signal) would be confusing for the operator; instead, the voter system provides a set of electronics that electrically compares the quality of the two signals provided by the two satellite receivers, selects ("votes") the better one, and then connects it to the dispatct console. In the case of a mobile-relay system, the voter also connects the better signal to the mobile-relay transmitter as well as to the console. The measurements show the talk-fo problems would be solved with a base station located at Ellery Reservoir and a single satellite receiver located in the La Costa area. (The interior of the mall will pose a problem for just about any solution that is proposed; this subject is discussed later.) This satellite receiver is not a total solution to the La Costa coverage problem since difficulties exist for hnndheld radios used inside b~ildings in that area; the base station is not always heard, and so a talk-out problem exists. The first alternative was recommended by the city• s service agency, and that is to add another base station in the La Costa area which could be selected by the dispatcher when a unit is known to be there that is having difficulty with reception. AcJding a single satellite-receiver voting system is not u large expPnse; adding an additional base station begins to make the e~pense significant and complicates the control at the console, and still would not produce total citywide communications. RG 252/ 4 11 I I r .I I ..... ' The second alternative would be to locate mobile-relay equipment at Squires Dam. This site has better talk-out characteristics than does Ellery Reservoir; in particular, it talks into the La Costa area sat:sfactorily. Squires Dam is not a per.feet site and has talk-in cover.age deficiencies from the Park-Kelly portion of the city, and so a satel~ite-receiver voting system would be required to make Squires an acceptable site. The thiro alternative would be to perform a more complete engineering study of the city. Temporary base stations would be set up on other hilltops an~ coverage effectiveness over the cit~• would be measured. Such an effort was not costed into this study because examination of a topological map of Carlsbad clearly showed that the city's many rolling hills and valleys created a teirain coverage problem; the likelihood of finding a single good coverage site was determined to be vanishingly small. The fourth option would be to install mobile-radio extenders in all of the Patrol cars. These allow a handheld radio to transmit to the ~ar, the car then repeats the signal (using its own higher-power transmitter) to the base stat.ion. Some departments use these but find them to be quite inflexible (an officer must have a car there with extender capability), the cost ic rather high, and a great deal of operational flexibility is lost. The fifth alternative woula be to ao nothing; in the long run, this could turn out to be the most expensive alternative of all shoul-=I some officer or citizen be injured or killed because of a communications lack. RO 252/ •I 12 5. RECOMMENDATIONS After consideration of the alternatives that could provide solutions to the CPD's raoio problems, a set of recommenuations were developed. These are presented in the paragraphs that follow, and are made with the knowledge that the city will be developing a new Emergency Services Center (ESC). This center will have upgraded dispatch equipment and will need an upgraded radio system; these recommendations should therefore be considered as a first step toward dev~lopment of the new center. On~ of the recommendations is that a new police frequency and base station be obtained, to be located at Squires Reservoir. The Squires Reservoir site would be particularly advantageous because of its ~roximity to the new ESC. If the city decides to adopt the following recommendations and obtain new equipment, the specifications will be such that the equipment will be compatible with the latest, state-of-the-art console equipment with which the new center should be furnished. If the city expends funas to carry out the recommendations, this will be in line with the development of the new ESC, the money will have been well spentr and the city will have taken the first step toward that new capability. 5~1 INTRODUCTION A. OBTAIN.A NEW FREQUENCY PAIR On the radio inte:rference problem, the recommendation is to obtain one (really a pair) new frequency and then move CPD dispatch operations to mobile-relay operations on the new, clear frequency pair. Since the solution for this und for the coverage problem interrelate, only one set of cost projections will oe made, and this solution will be RG 252/5 13 /1../- " ~~ . • ·l .. ·'..{ . 1 folded into the different alternatives proposed for the coverage problem. The only additional cost to that required to solve the coverage problem would be to change the crystal frequency elements in the mobile and handheld radios. Present costs run about $200 per channel, and there are presently about 35 mobile and portable; the budgetary estimate is $7,000. B. RETAIN A BACKUP SYSTEM Coupled with the recommendaiion to seek a new frequency is the suggestion of retaining the present CPD dispatch frequency and base station. The CPD is growing to the size where it could well use a second (tactical) police frequency to keep the dispatch frequency clear for its fun- damental purpose. Although the present frequency suffers from interference, this interference would not be so destructive to tactical operations, which are generally close in, unit-to-unit in nature. The present base station could be left as is, and the present dispatch channel in the mobile and portable radios left as is; this could then be used as a second frequency. If the following recommenda- tion to place the new equipment at Squires Darn is adopted, the present base station at Ellery Reservoir could provide an important degree of geographical redundancy for the city; if something were to happen to the Squires Dam site {e.g., airplane accident, telephone-line failure), the ' Ellery Reservoir installation would serve as a backup. 5 • 2 COVERAGE A. OBTAIN A MOBILE-RELAY ANO SATELLITE RECEIVER A recommendation on the coverage problem is to obtain a mobile-relay station and a satellite receiver, locating the mobile relay at Squires Dam and the satelli_te receiver RG 252/5 14 . ' i (perhaps at Ellery Resecvoir) to co•1er the Park-Kelly por- tion of the city. Cost estimates for Alternatives A and B are listed below. The A alternative is more expensive because a second base station would be required to provide full coverage in La Costa. B. IMPROVE MALL COMMUNICATIONS It must be pointed out that a second base station such as this would somewhat negate the advantage of mobile-relay operation, since coverage from the station in La Costa would be limited and since it would still be possible for a mobile unit to transmit from the other end of the city without realizing that a small handheld radio is using the s:hannel. Coverage from the very interior portions of the mall will continue to be a problem (as it is in almost every mall in the state) • Wi~hout installing equipment directly in the mall, it is very difficult to get signals \nside and outside of these monstrous and well shielded structures. A possible solution might be adapted to Carlsbad, which would be to use a pair of small, parasitic antennas to get tre signals into and out of the mall without the use of any electronics. such has yet to be attempted, but the City of ·•est Covina is funding the Richter Group to attempt an experiment on their mall to establish whether this solution would be satisfactory. If satisfactory, the cost would be that of a pair of antennas, a short run of connecting cable and installation. 5.3 ADDITIONAL ACTION REQUIRED Additional action is required to complete the frequency coordination and application process. Candidate frequencies have been id~ntified for a mobile relay. The application-and- RG 252/5 15 f (,. / r.oordination process has been initiated. The two frequencies selected are both used by the Torrance Police Department for a mobile-relay system: Torrance will undoubtedly want tests to confirm the suitability of Carlsbad as a co-channel companion and arrangements will be made for these in the near future to estabUSh the usability of tbis frequency. After that, if the city so desires, application for the new frequencies will be made to the Federal Communications Commission. Purchase specifications for ~is mobile-relay station, satellite receiver, and comparator-voter will be p~epared. 5.4 COST ESTIMATES PRICE ITEH QTY A. NE\>!

Jimno, Chief of Police~ COMMUNICATIONS RECOMMENDATIONS Dr. Richter's consulting study was received on April 4, 1983. After review and consieration, I believe his recommendations to be a sound alternative to the present communications problems. Subsequently, I would recommend that: 1. The recommendations be approved by the City Council, and that we request allocation of funds from savings in the present police budget. 2. Dr. Richter be given approval by the City Council to proceed with his efforts to obtain a sui.table frequency for the changeover. It appears that these recommendations will fulfill operational requirements of the proposed Public Safety Center, as well as the current Communications Program. It also appears that the recommend- ations would be a final solution to our past problems. In addition to Dr. Richter's recommendations, I have included some changes that were not part of Dr. Richter's study, but that he none the less endorses. The additional recommendations are for the purposes of improving our operational effectiveness. I would there- fore recommend the following: 1. Purchase panel mounts for existin~ Call Directors@ $1800 x 2 = $3600. (These would enhance the 11 911 11 System and will improve the dispatchers' ability to manage telephone and radio traffic.) These would be transferred to the new facility. 2. Purchase dispatch head sets for all dispatchers, and require their use, @ $200 x 10 = $2000. (This coincides with the installation of the Call Directors and will improve dispatcher efficiency.) 3. Purchase of a sound cover for existing C.L.E.T.S. printer. This printer causes interference of both operators and radio dispatch. Cost: $400. 4. Purchase a battery pack for the dictaphone recorder. This will allow continued recording of emergency radio traffic during power failures. Cost: $250. 5. Purchase two (2) Call Counters for each Call Director. These counters will enable us to determine the amount of telephone work loads in the Communications Center. Cost: $225 each= $450. / I -.,,........------------------------ The total cost of the program to solve the problems in the Communications Division would therefore be: Communications Study $ 3,327 Frequency Change-Out $ 23,300 Equipment Improvement $ 62700 $ 33,327 Less previously paid study $ 32327 $ 30,000 (ESTIMATED) I have attached two copies of Dr. Richter's report for your review.
