ATTACHMENT 1—Project Narrative <br /> AT&T's Application—HIL03306 Volcano Village East <br /> Page 11 of 17 <br /> • High-band SG+ mmWave. High-band millimeter wave (mmWave) frequencies (generally <br /> 20-100GHz) are the new FCC-approved frequencies most associated with 5G service— <br /> "5G+" is AT&T's name for 5G service delivered using high-band mmWave spectrum.AT&T <br /> offers an enhanced wireless experience on 5G+with mmWave service though with more <br /> limited coverage. Results continue to be impressive, with peak download speeds up to 1 <br /> gigabit per second (Gbps) — fast enough to stream 4K movies. High-band mmWave <br /> frequencies deliver this unprecedented performance by transmitting a large amount of <br /> data more efficiently than 4G LTE, but can only travel short distances (-1,000ft). <br /> Accordingly, high-band mmWave sites need to be in close proximity to one another and <br /> are typically used in dense, high trafficked areas such as urban areas, stadiums/arenas, <br /> airports, manufacturing and healthcare centers, etc. <br /> 5G wireless technology also includes enhanced network radio protocols and other <br /> improvements in data transmission that allow the network to more efficiently use the <br /> same frequencies currently used today for 4G. <br /> As noted, AT&T is proposing to deploy low-band 850MHz 5G at this Facility. Upon completion, <br /> the Facility will become part of AT&T's statewide and nationwide communications networks. <br /> 3.2 Statement of Objectives for Proposed Facility <br /> This proposed Facility meets AT&T's service objectives (providing outdoor, in-vehicle, and in- <br /> building wireless coverage) by filling a gap in AT&T's 4G LTE network coverage experienced by <br /> its customers between Glenwood and Old Volcano community area. As well as, along the main <br /> highway between these areas. The Facility also meets AT&T's objective to provide expanded <br /> FirstNet coverage for first responders (as further detailed in Section 4, below). In addition to <br /> expanding the 4G LTE network, this site will also expand AT&T's 5G network in support of the <br /> next generation of wireless technology using low-band 850MHz 5G . (See Attachment 3—AT&T <br /> RF Justification). <br /> AT&T has determined a need for service in this geographic area through a combined analysis of <br /> market demand, service requests, radio frequency engineering design, and input from public <br /> safety officials. This proposed Facility will provide all AT&T/FirstNet customers with reliable <br /> wireless service in the Targeted Service Area, including fewer dropped calls, improved call <br /> quality, and emergency 911 calls. The FirstNet network will allow the utilization of the priority <br /> and preemption feature and wireless applications (Computer Aided Dispatch (CAD), Records <br /> Management System (RMS), Geographic Information System Mapping (GIS), etc.) for faster <br /> response and situational awareness, especially during emergency events. <br /> 4. FIRSTNET <br /> FirstNet is the country's first nationwide communications platform dedicated to public safety, <br /> representing a giant leap in communications capabilities for public safety personnel that will <br />
