    E R I C S S O N R B S 2102 / 2ior F O U R - G A BI N E T O P E N S Y S T E M I N S TA L L A T IO N SAt your reqiiest, this letter provides noise planning information for a Cinguiar cellular systemutilizing four outdoo r BTS EB S 2102/2106 cabinets. This rep or t prese nts the analysis base d on an"open plan," where the facility is surroinided by a chainlink fence and is located at the minimuminstallation distan ces vSpecified in the rep or t from any pro pe rty line or onsite building.Noise and S ound Level DescriptorsAll noise level or sound level values presented herein are expressed in terms of decibels (dB), withA-weighting, abbreviated "dBA," to approximate th e hearing sensitivity of humans. Tim e-ave ragednoise levels are ex pressed by the symbol L^Q, for a specified duration. Short duration peak noiselevels are exjDressed by the symbol L^AX- '^he Community Noise Equivalent Level (CNEL) is a24-hour average, where sound levels during evening hours of 7 p.m. to 10 p.m. have an ad ded 5 dBweighting, and sound levels during nighttbne hours of 10 p.m. to 7 a.m. have an added 10 dBwe igh ting . This is similar to th e D ay-Ni gh t sound level, Lp,M, which is a 24-hour average with 10 dBadded weigh ting on the sam e nighttime hours but no added weighting on the evening hou rs. So undlevels expressed in CN E L ar e always based on A-weighted decibels. These data un it met rics areused to express noise levels for both measurenient and municipal noise ordinances and reg ulat ion s,for land use guidehnes, and enforcement of noise ordinances. Some of Uie data may also bepresented as octave-band-filtered and/or -octave-band-filtered data, which are a series of soundspe ctr a cen tered about each state d frequency, with half of th e bandw^idth above and half below ea chstate d freque ncy. This da ta is tyi:)ically used for machinery no ise analysis and bar rie r effectivene sscalculations. (Pvn-ther explanation can be pvo^nded upon req ue st.)Noise emission data is often sup phed per the industry stand ard form at of Sound Power, which is th etotal acoustic power radiat ed from a given sound source as rel ate d to ai-eference power level. SoundPow er should not be confused w ith Sound Pressure, which is th e fluctuations in air pr es su re causedby the presen ce of sound waves, and is generally the format tha t describes noise levels as h eard bythe receiver.

    Applicable Noise Stand ardsThe applicable regulations for these projects are contained within the relevant comm unity or Countyof San Diego'municipal code (noise ordinances). These ordinances tyiMcally provide t h a t the hourlyaverage noise limit for any noise source impinging on a single-family residential zone is n o t to exceed45 dBA between the hours of 10 p.m. to 7 am. (nighttime hours). However, some municipalities,including the City of San Diego, have a more restrictive nighttime noise Umit of 40 dBA . Daytimenoise limits are normally less restric tive, allowing 5 dBA higher noise levels during th e hours of 7a.m. to 10 p.m. Noise hmits are also less restiictive in commercial and induatrial land u se zones.Potential Project-Related Noise Source(s)These installations propose to install four RBS 2102/2106 telecoimnunicationa cabinets (these arefunctionally sumlar units and nearly identical for noise emission and noise planning pur-poses),within planned equipment enclosures. The predominant noise sources from each equipment cabine tare the intake and exhaust louvers, located on the front side of each equipment cabinet. Theequipment cabinets are expected to operate 24. hours per day, 7 days per week, 365 days per year.-Similar Equipment N oise Emission M easurementsTo accurately assess th e expected equipment noise levels from the proposed installation, no ise levelsof similar operational equipment cabinets were measured at 10:30 a.m. on October 17, 2002, at aCinguiar wireless installation located at the "Strouds" store in Mission Valley, Saa Diego. Theequipment cabinets were installed inside an enclosed second-floor room. Access to the equipmentenclosure was via a ladder and hatch from an outside entrance.The2n-footby 14-foot equipment room containing the operational cabinets had a 10-foot hig h ceiling.The i oom was highly reverberan t, due to the plywood floor, three sheet-rocked walls and ceiling,and thefourth wall which appeared to have originally been a sprayed stucco exterior wall. Installedin the room were three RBS 2102 cabinets, all in operation. The equipment was situ ated in an "L"shape around two walls, ^dth tl)e ventilation louvers (noise sources) facing toward the cen ter of theroom. Outside noise sources were negligible.The similar equipment noise emission levels were measured with a Larso n Da\ds Model 824, Type1 Sound Level Meter, Serial #342 (with windscreen), and Larson DaAus Model CA200, Type 1Calibrator, Serial #2181. The sound level meter was field-cahbrated immediately prior to th e noisemeasurements and checked aftenvards, to ensure accuracy. All sound level measurementsconducted and presented in this report , in accordance with the regulations, were made with a soundlevel meter tha t conforms to the Ameiican National Standards Institute specifications for soundlevel meters (ANSI SL4-1971). All insti-uments are maintained vith National Bureau of Standardstraceable calibration, per the manufacturers' standards.

    The Lai son Davis 824 sound level meter was mounted on a tripod in the approximate c en te r of theroom at a distance of approximately six feet from the two end (of the "L") cabinets an d eight feetfrom the corner cabinet. The measured overall noise level for a one-minute measurement was56.8 dBA., The octave d ata is summarized in Table 1; the full-octave data table is provided asAttachment 1. The Ericsson RBS 2106 data sheet is provided as Attachment 2.

    Due to the reverbe ran t room effect on the noise measurements, th e measured noise levels of theoperational equipment provide a maximum worst-case noise emission level for the equip mentcabinets. Thus, when these measurement data are utihzed "as is," the resultant analysis will beconsei'vative.Project-Related Equipment Noise LevelThe measured noise data for the three-cabinet installation has been multiplied by 4/3, to pro\ddeanalysis for the future proposed Cinguiar four-cabinet installations.The calculated noise level of the proposed four-cabinet installations is 58.1 dBA LEQ, as shown inTable 2.

    Distan ce A ttenimtionAtten uation due to distance ia calculated by the equation SPL^ - SPL^ - 20 * Log (Dg/Di) where:SPLi = Calculated sound pressure level at distanceSPLg = Kno^m sound pressure level at known distanceDi Distance from source to known sound pressure levelD2 = Distan ce from source to location of calculated sound pressure levelThis is identical to the more commonly used reference of 6 dB reduction for eveiy doubling ofdistan ce. This equation does not take into account reduction in noise due to atmospheric absorption.Tables 3 and 4 presen t calculated distances for the targe t nighttime noise levels (40 an d 45 dBA),for soft-surface and hard-surface environmeiits.In a hard-surface environment (pavement or concrete suiTOunding surfaces), the noise level at anygiven location will be a maximum of 3 dBA higher than in a soft-surface environm ent, due to thereflectivity of the ground between the source and receiver. The noise level calcidationa in Table 3account for this difference.

    Required Distances for 45 dBA Nighttime Property Line Noise Lim itWhen the area around the proposed facility consists of soft surfaces, such as loose dirt or grass, th eequipment must be placed at a distance greater than 27.1 feet from the nearest impacted location,to provide a noise level below 45 dBA L^Q.If the proposed facility is surrounded by hard surfaces, such as hard packed dirt, pavement, orconcrete, the equipment m ust be placed at a distance gre ate r th an 38.3 feet from the neare stimpacted location to provide a noise level below 45 dBA L^Q.Required Distances for 40 dBA Nighttime Property L ine N oise Lim itWhen th e a rea around the proposed facility consists of soft surfaces , such as loose dirt or grass, theequipment must be placed at a distance greater than 48.2 feet from the nearest impacted locationto provide a noise level below 40 dBA.If the proposed facility is surrounded by hard surfaces, such as hard packed dirt, pavement orconcrete, the equipment must be placed at a distance greater than 68.1 feet from the nearestimpacted location to provide a noise level below 40 dBA.On-Site Residences or B uildingsThe above described distance limitationsmustalso pertain to on-site residences and other buildings,both to provide quality of life for residents and to preven t noise reflections (which would increasethe required distances for property line noise limit compliance).LimitationsTills analysis is based on the noise emission for the fan side (front) of eacli cabinet, to present aworst-case analysis, since the fans are th e loudest noise source. A ccordingly, it is safe to assume thatthe orientation of a planned installation will not cause the projected noise level to be highe r thancalculated in this analysis.Since the measured noise levels of the other three sides of the cab inets will be lower, the minimumrequired distances from the remaining three sides may be somewhat less than indicated above.However, a separate analysis of the specific installation would be required to determine thesedistances, which may b e useful in proposed locations with space limitations.Tlie analysis and results presented in this report are based on the best data available for theEricsson RBS 2102 / 2106 cabinets only; the results are not valid for other t pes of units or inconjunction -v ntli air conditioning equipment. There may be minor variations in noise emission fromsimilar units.

    Part o f t he g row-on -s i te conce p tSince il is becoming increasingly difficult to find newbase station sites, it is of great Interest to remain onexisting sites as long as possibie. Site space Is oftena limiting factor for capacity growth. Uie powerful RBS2"! 06 , Inc luded in Ericsson's grow -on-s ite loo lbox,addresses this problem.On many sites, two or more existing cabinets canbs replaced by one RBS 2106, thereby solving the siteapace problem by making room for another cabinet.This is of major importance, since it makes It possiUato reuse and collocate GSM and WCDt^A equipment.Furthermore, the plug-ln WCDMA transceiver unit(W-TRU) can later be direcliy housed in the RBS 2106.

    Doubled capaci ty- super io r per formance - same footpr in tThe 12-transGeiver RBS 2106 cabinet has the samefootprint as RBS 2102 but has doubled capacity, thanksto new double-capacity transceivers and combiners.

    The double transceiver unit (dTRU) lias some powerful features. The R BS 21 (16 has better outpt i t powerthan cuirent RBS 2000 products, wt^ich are the best onthe market today. The improved radio performancesmean increased slte-to-slte distance, and therofora,fewer sites. Another example of a cost saving feature Is121 km Extended Range.

    The RBS 21 OB comes with two new, extremely flexible combiners. Examples of configuralions for 900 andiaoo tyll-tz, supported by the filtar combiner (CDU-F),are 3x4, 2x6, 1 x12 and dual band'8-i-4 or 4-1-8 in onecabinet. CDU-F supports up to 12 tr-ansceivers. Theother combiner (CDU-G) for 900, 1800 and 1000 MM2can be configured In two modes; capacity mode andcoverage mode, making It very flexible. In coveragemode, the output pow er from the C DU-G Is increased,malclng it perfect for rural sites or when fast rolloutis required at a minimum cost. To build a 3x4configurat ion, one RBS 2106 cabinet is equippedwith three CDU-Gs.Prepared fo r the fu tur eThe RBS 2000 family is prepared for GSM data seivices,including General Packet Radio Sen/ice (GPRS), HighSpeed Circuit Switched Data (HSCSD) and 14.4 l;blt/stimes ots.

    To meet the operators' need for faster datacom so lu t ions, RBS 2106 supports 6D GE. A powerfu l Distr ibut ionSwitch Unit (DXU) and fast Internal buses guarantee fullEDGE support. This new DXU Is also prepared for IPbased Abis transmission.

    With the opt ional BSS feature RBS 2000 synchro nizat ion, It Is possible to have up to 32 transceivers In oneceil. With the opt ional BSS feature RBS 200 an d RBS20QQ in the same cel l , i t is possib le to expan d an existing RBS 200 cell with RBS 2106, and thereby IntroduceEDGE and WCDMA through plug-in units.
