ATTACHMENT 1—Project Narrative AT&T's Application—HIL03306 Volcano Village East Page 10 of 17 The Property is in Flood Hazard Zone X: "Areas determined to be outside the 0.2%annual chance floodplain"(see Attachment 12—Flood Hazard Report). 2.3.7. Community Engagement Majority of the surrounding properties are undeveloped. Adjacent property owners within 500' will be notified of the proposed project. (See Attachment 9—List of Property Owners). 3. AT&T NETWORK COVERAGE AND SERVICES 3.1. Overview—AT&T 5G and 4G LTE AT&T is upgrading and expanding its wireless communications network to support the latest 5G and 4G LTE technology. 5G and 4G stand for "51h Generation" and "4th Generation" and LTE stands for "Long Term Evolution." These acronyms refer to the ongoing process of improving wireless technology standards, which is now in its 51h generation. With each generation comes improvement in speed and functionality-4G LTE offers speeds up to ten times faster than 3G and 5G offers speeds up to 1-gigabit per second (See Attachment-3 RF Justification). This technology is the next step in increasing broadband speeds to meet the demands of uses and the variety of content accessed over mobile networks, and is necessary to facilitate capabilities that are being designed into the latest devices (i.e. Samsung Galaxy S22, iPhone 14). 5G, specifically, is the next generation of wireless technology expected to deliver latency and capacity enhancements that will help enable revolutionary new capabilities for consumers and businesses. There are several components of 5G wireless technology and separate bands of wavelength spectrum used to build a 5G network: • Low-band 5G. Low-band 5G frequencies (generally below 2GHz) are the oldest cellular (and TV) frequencies and are being used by AT&T to provide widely-available 5G service in residential, suburban, and rural areas. This is the same spectrum used for 3G and 4G today. The low-band 850MHz 5G frequency is proposed for this Facility. Low-band 5G frequencies are a tradeoff of download speed versus distance and service area—they are slower than the high-band mmWave and mid-band frequencies, but they travel the farthest and can pass through more obstacles to provide a better, more reliable indoor and outdoor signal for a larger service area (i.e., miles, not feet). • Mid-band 5G. Mid-band 5G frequencies (generally 3-10GHz) cover most current cellular and WiFi frequencies and provide broader coverage than high-band mmWaves (typically a half a mile), but with slower speeds. Use of these frequencies is not as prevalent for building a 5G network as much of the bandwidth in this range is currently unavailable.
