Approved 3113117 1 Ben Levitan: Ok, do you want me to show... if you could put up this slide please, it's the first 2 colored slide... We can start with the... Ok, let me stop at this slide first. Wireless demand has just 3 started crazy, we all know that. The largest growth is in video, number one. It's just blowing 4 everything away and it's expected to continue so with that in matter understand Mount Carmel 5 Road does not need improvements for video. I think we got enough people driving and using their 6 devices ..... we certainly don't need to improve video performance on Mount Carmel Road. Ok so 7 that aside let's go to the next slide. Ok the two stated goals like I said, there's one we're going to 8 improve coverage over on Mount Carmel Church Road between the Governors Club area and 9 Chapel Hill. Second stated goal is provide an offload for UNC Campus where, yes, the demand is 10 growing, mostly because young people are sitting around watching videos. Ok so let's go on that 11 slide. And we can just stop briefly... When we have gaps in areas there's a couple things we do. 12 We add an extra cell tower. We can go to the next slide. And so that would be the Mount Carmel 13 area. And when we have incredible demand in one area, what we call a macro cell, a lot of times 14 you'll find that there's a very small area within that macro cell that needs extra capacity so we can 15 put in small cells to cover that. Student union, what do you call it? The gathering area. There's 16 certain areas that you can offload by putting in small cells. Ok go on... 17 18 Samantha Cabe: What do you mean putting in small cells? 19 20 Ben Levitan: Ok... There's basically two types of cell towers that exist. There's what we call macro 21 cell, 191 -foot tower. It puts out... A cell tower's just like a radio station. When you're under the 22 coverage of that cell tower, that radio station, that 191 -foot cell tower, it essentially goes out, 23 technically, out to 25- miles. It could cover everybody in a 25 -mile radius, which is no (inaudible). 24 Generally, in an area like Chapel Hill we're only going to go out of like 2 -miles and if you guys 25 remember your algebra from high school and remember pie r squared you thought you, you 26 thought you'd never use that, you get to use it today. A cell tower that goes out 2- square miles 27 to... it covers 12- square miles. So a typical cell tower in like a suburban area like Chapel 28 Hill /Raleigh, it's going to cover about 12- square miles. Ok so that's a macro cell. This is what 29 we're talking about, small cells, which is something that's new, it's not new, it's something that's 30 rolling out very rapidly. It's rapidly going to take over. A couple years from now you won't see a 31 cell tower, this will not even be an issue anymore. The cell tower's are going from those large cell 32 towers to much small cell towers. These are about the size of a Rubik cube. They're very 33 inexpensive, about $400 a piece, and generally we're putting them on every lamppost in town. So 34 instead of covering 12- square miles you're only covering one block, but it's got tremendous 35 advantages because for number one, those little cell towers provide better coverage for smaller 36 areas, obviously you need a lot more of those, sixty to cover the same area that this cell tower is. 37 Overall, they're a lot cheaper for the companies and greater service. So one of the greatest 38 benefits is 911 service. When you call 911, 1 was one of the people who developed 911, 1 have 39 patents in that area... when you call 911 a tall cell tower and get you to about a half a football 40 field. We can locate you 65% of the time to 150 -feet. That's what we're requiring cell towers to do. 41 These new cell towers, since they're only going to be a block, they're going to be able to locate 42 people to a matter of 50 -feet. And so for a lot of reason, one for financial reasons, one for safety 43 reasons, we're all going to these smaller cells. This is going to be more efficient. And the FCC 44 back 2015 just cracked up the accuracy that we need to provide for 911. And these small cells are 45 lower power. The other big benefit for us, a lot of them are using an unlicensed frequency. Think 46 of them as like Wi -Fi. They're totally unlicensed. So instead of doing all the things we have to do 47 for a tall tower to use the licensed frequency... It just makes life a lot easier. One of the greatest 48 benefits is when you're in a high rise. Instead of having one cell tower outside that power is 49 providing coverage to everybody inside. You can put one of these small cells on every floor of a 50 tall structure. And one of the greatest benefits is if someone calls 911 on the 15th floor you know OC Board of Adjustment — 12/12/16 Page 106 of 156
