1. OverviewThis RF Report has been prepared on behalf of AT&T for itse lf and on behalf of the First Responde r NetworkAuthority (,,FirstNet,,) in support of its application ro the Town of South Yamouth for the installation and operationof a wireless facility locate d at 1044Route 28 in south Yamouth, MA' The proposed facllity is needed to fiIl acovefag1egap that cufrently exists in AT&T's nerwork, while providing prioritized' preemptive wireless servicesfor first responders,AT&T,s proposal consists of ground-based equipment cabinets and antennas mounted on top of a proposed towerat a height of 100 feet. The proposed Facility has been selectecl by FirstNet as suitable for implementation of theNational public safery Broadband Nenvork (,NpsBN'), while also addressing a substantial gap in 4G LTE coveragefor AT&T's network.This reporr concludes that the proposecl site will provide covefage improvement to areas of south Yarmouth in orderto improve clcficient seryice ur.u, ,long Forest Road, state Highway 2S,LongPond Road and the surroundingroads and neighborhoods in the proximity of the proposed site'Included in this report is: a brief summafy of the site's obiectives, maps showing AT&T's neighboring sites' andpredicted Radio Frequency coverage maps of the subiect site an<i the surrounding sites in AT&T's network'2. IntroductionAT&T is licensed by the FCC to provide wireless communications services throughout the Northeast Regionincluding the Town of south yamouth, MA. AT&T provides rtigrtal voice and daa serviccs using 3rd Generation(3G) UMTS technology in the 800 MHz and 1900 MHz frequency bancls, and is deploying advanced 4th Generation(4G) voice ancl data services over LTE technology in the 7c0 MHz, 850 MHz (Cellular), 1900 MHz (I)CS)' 2100 MHz(A\flS), and,2300MHz flJfCS) bands, u. u[o.uJ by the FCC. The 4G LTE net'work builds on the existing 3G dataservices that utilize uwrs technor.gy. These data networks are used by mobile devices for fast nrcb browsing, mecliastreaming and other applications that require broaclband connections. As part of AT&T's network expansion andenhancement in Massachusefts and elsewhere in the United States, AT&T is filling in existing covefage gaps andaddressing capacity,interference, and high-speed broadband issues. The mobile devices that beneftt from theseadvanced data nerworks are not limited to basic hanclheld phones, but also include devices such as smaflphones'pDA's, tablets, ancl laptop air-cards. rwith the evolving rollout of 4G LTE services and devices' AT&T customefswill have even faster connections to people, informat-ion, and entertainment'FirstNet is a fecleral agency with a mandate to create a nationwide, interoperable public safety broadband nerwork forfirst responders. First responders across the country curtently rely on rnofe than 10,000 separate radio networkswhich oftentimes do not interoperate with one another. By deploying a nationwic{e broadband public safety netw<;tkbuilt specifically to meet the cornmunicadons needs of first responclers, the FirstNet nefwork q'ill provide a solutionto the decadesJclng interoperability and communications .hull"tg.s first responders have experienced' and whichwas highlighted by the 9/1'7 Comrtission's 2004 Final Report'F-irstNet selected AT&T to burlcr, manage and operate the National public safety Broadband Network ('NPSBN')usingFirstNer's Band 14 spectrum (ca[signwQ QE234,20MHz of the700 MFIz spectrum)' togetherwith AT&T',sown wireless nerwork, Using a combination of new ancl existing wireless facilitics, AT&T provides prioritized,preemptive wireless services for first responclefs across Massachusetts, New lingland and nationwide' while als<;C Squatecl Systems, l-LC 1 July 6' 2020
improving 4G LTE coverage for AT&T customers. AT&T works closely with local' state, and federal first respondersin designing the FirstNet network and selecting each nerv site'AT&T's network requires the strategic deployment of antenna sLructufes throughout the atea tcl be covered' whichare connected to receivers and transmittefs that opefate in a limited geographic area known as a "cell"' Mobilesubscriber handsets and wireless devices operate b)'tr^t"miming and receiving low power radio frequency signals toand from these cell sites. The srgnals afe tfansfeffecl through gound telephr:ne lines (or other means of backhaulffansport) and routed to their clestinations by sophisticated electronic equipment' The size <sf the atea served by eachcell site is dependent on sevefal factors inclucling the number of antennas used, the height at which the antennas afedeployed, the topography of the surroundifig land, vegetative cover' and natural or man-made obstructions in thearea. As customers move throughout the service area, th.transmission from the portable device is automaticallytransferred to the AT&T facility with rhe best reception, without interruption in service, provided that there isovedapping coverage between the cells'In order for AT&T,s netuvork to function effectively, there must be adequate ovedapping coverage between the..serving cell" and "adioining cells". This not only allows access to the net'work, but once connected allows for thetransfer or ,,hand-offl, of calls from one celi to another and prevents involuntary disconnecdons or "dropped calls'"AT&T,s antennas also must be located high enough above ground level to allow uansmission (a'k'a' propagation) ofthe radio frequency signals above trees, buildings and other nahual or man-made structufes that may obsttuct ordiminish the signals. Areas without adequate ,udiu fr"q.r"rrcy coverage have substandard service characterized by poorvoice quality, clropped and bbcked calls, slow data connections and transmissions, or no wireless service at all' Thescareas arecommonly referred ttl as "coverage gaps'"r*e have concluded that by instailing the proposed wireless communication facility <;n the proposed towet at 1'044Route 2g at an ^ntennacenteline height of 100.0' AGL (above ground level), AT&T will be able to provide additionalcapacityand coverage improvement to residents, businesses, and tafftccorridors within Yamouttr that are currentlylocated withir-r deficient servtce areas of AT&T's network'2C Squared Systerns, LI-,CJ:u/ry 6,2020
3. AT&T Mobility Coverage and Capacity ObjectivesIn order to expand and enhance their wireless services throurghout New England' AT&T must fill in existing coveragcgaps anci acldress capacity, interference, and high-speed broadbancl issues' As part of this effort' AT&T hasdetermincd that significant gaps in service exist in and around sections of the town of Yamouth, MA, as describedfurther below.AT&T currently operates wireless faciliues similar to the proposed faciliry within Yamouth and the surroundingcities/towns. Due in large part to the distances betwecn the exrsting sites, the intervening topography, and voiumeof *ser traffic in the area,these existing faciliries do not provide sufficient coveragc to porrions of South Yamouth'Specifically, AT&T determined that much of area known as Sourh Yamouth is without relable service in the followingareas and town roads, including but not limited to:r Forest Road;r State Highway 28;. LongPondRoad;r The surrounding roads, neighborhoods ancl businesses in the proxirriry of the prop<lsed site and theabove-mentir-rned road,4.
