1 unacceptable service, and using an application called "Mark the Spot" which automatically notifies <br />2 AT&T of unacceptable quality of service in a specific geographic area. <br />3 1 compiled the complaints that were made during 2014 and 2015, and geo-coded the locations <br />4 of the complaints onto a map which is attached as Exhibit 3 to Littlefield Declaration. As you can see, <br />5 AT&T's customers' complaints also show that there are significant gaps in coverage in the general area <br />6 around the proposed site. The geo-coding process is accurate to within two or three city blocks, taking <br />7 into consideration the delay in reporting an incident, and the difference in performance among <br />8 handsets. <br />9 Microcells. AT&T offers a product called a "microcell" or a "femtocell" that is designed to <br />10 improve the quality of AT&T's service while indoors. Customers purchase the microcell when they are <br />11 experiencing an unacceptable level of service while indoors. When the microcell is powered "on" and <br />12 connected to the customer's home/office Internet connection, and the microcell uses GPS signals to <br />13 identify the precise location of the microcell (for E911 location purposes) and registers its location with <br />14 AT&T's E911 database. When there is a high density of microcells in a geographic area, it is a strong <br />15 indicator that AT&T's network is not providing an acceptable level of indoor service in that geographic <br />16 area. I have attached as Exhibit 4 to Littlefield Declaration a copy of a map that shows the location of <br />17 microcells registered with AT&T in the area surrounding the proposed EG46 site. The large number of <br />18 microcells in the area is another clear indication that there is a significant gap in AT&T's coverage <br />19 throughout the area. <br />20 1 have determined that AT&T must improve the quality of AT&T's service within this significant <br />21 gap in coverage. Based on my education and experience described above and my comprehensive <br />22 analysis of the data associated with this proposed site, I hereby certify that my RF Justification and the <br />23 project narrative are true and accurate, to the best of my knowledge, and form the basis of my analysis <br />24 and opinion. <br />25 3.
