AT&T i~as several ways to connect custorners to our network to provide quality and reliable wireless service including macro <br />cells, small cells, and distributed antenna syster-n (DAS) facilities When it comes to choosing the type of technology there <br />is no one size fits all solution. AT&T carefully weighs a number of factors, like population density, capacity needs, <br />topography and variability of traffic, when deciding which option is best for an area <br />Macro Cells: <br />The most common type of wireless facility is frequently referred to as a "macro cell", or simply a "macro." Macro <br />cells form the core of wireless networks, enabling wireless service providers to deliver voice, Lext and broadband <br />communications. Macro cells have been constructed in many different sizes, con fig~_irations and heights. Some macro <br />cells may incorporate techniques to hide the antennas from normal view or be camouflaged as trees or other structures <br />to blend in with the surrounding area. Macro cells are effective for covering large geographic areas, especially in rural <br />situations, v/ith relatively high capacity, and do so because the antennas transmit radiofrequency (RF) signals at higher <br />power levels than smaller cell architectures, such as metro cells, micro cells or pico cells. <br />In urban areas, macro cells are often placed on existing structures, such as building rooftops or water towers. Although <br />not in all cases, macro cells are generally on structures over 30 feet in height and placed at locations with higher ground <br />elevation, utilizing a set of larger panel antennas to achieve this broader geographic reach. Based on their reach, macrc <br />cells provide the most effective coverage for a ~niireless network with the fewest number of sites. <br />Small Cell Technology: <br />A small cell is a flexible, innovative, new technology that <br />improves network performance and provides users with <br />capacity and coverage in areas that can't effectively be <br />served by a traditional cell tower. Small cells help <br />extend the capabilities of ATBeT's macro network by <br />placing stand-alone radios throughout a building, facility <br />or neighborhood and connecting small cells with cabling <br />or fiber to a transport circuit. <br />Serves up to <br />Serves up to <br />Serves up to <br />32 <br />Simultaneous <br />Simultaneous <br />Simultaneous <br />Calls <br />Calls <br />Calls <br />Indoor <br />Home & Small <br />Business <br />41 <br />Indoor& <br />Outdoor <br />i <br />Big Office & <br />Neighborhood <br />Indoor & <br />Outdoor <br />X 8 <br />Public <br />Venue <br />r4IGIL M <br />3G <br />L!iZ!~ <br />Small cells are low profile, compact, scalable and unobtru- <br />sive. Depending on the need, small cells can be placed in <br />buildings or outdoors. 1Nhen placed outdoors, small cells <br />can be attached to existing utility poles, light poles or to <br />the exterior of a builcling. Indoors, small cells can be placed <br />above ceiling tiles, attached to drop ceiling mounts or <br />placed in telecom closets. <br />Small cells are most often used in dense urban <br />environments where capacity is an issue or in places with <br />particularly difficult geographical challenges where <br />coverage is an issue. The size _and flexibility of small cells <br />helps AT&T target unique capacity and coverage areas, <br />ho~n~ever, small cells do not replace the need to add to our <br />network with new macro cell sites. <br />Small cells are a resourceful network solution that AT&T is <br />deploying W provide consumers r,~~ith rlexible capacity and <br />coverage where it's needed most <br />
