DRAFT <br /> <br />OC Board of Adjustment – 11/9/15 Page 106 of 156 <br /> <br />Ben Levitan: Ok, do you want me to show…if you could put up this slide please, it’s the first 1 <br />colored slide… We can start with the… Ok, let me stop at this slide first. Wireless demand has just 2 <br />started crazy, we all know that. The largest growth is in video, number one. It’s just blowing 3 <br />everything away and it’s expected to continue so with that in matter understand Mount Carmel 4 <br />Road does not need improvements for video. I think we got enough people driving and using their 5 <br />devices ….. we certainly don’t need to improve video performance on Mount Carmel Road. Ok so 6 <br />that aside let’s go to the next slide. Ok the two stated goals like I said, there’s one we’re going to 7 <br />improve coverage over on Mount Carmel Church Road between the Governors Club area and 8 <br />Chapel Hill. Second stated goal is provide an offload for UNC Campus where, yes, the demand is 9 <br />growing, mostly because young people are sitting around watching videos. Ok so let’s go on that 10 <br />slide. And we can just stop briefly… When we have gaps in areas there’s a couple things we do. 11 <br />We add an extra cell tower. We can go to the next slide. And so that would be the Mount Carmel 12 <br />area. And when we have incredible demand in one area, what we call a macro cell, a lot of times 13 <br />you’ll find that there’s a very small area within that macro cell that needs extra capacity so we can 14 <br />put in small cells to cover that. Student union, what do you call it? The gathering area. There’s 15 <br />certain areas that you can offload by putting in small cells. Ok go on… 16 <br /> 17 <br />Samantha Cabe: What do you mean putting in small cells? 18 <br /> 19 <br />Ben Levitan: Ok… There’s basically two types of cell towers that exist. There’s what we call macro 20 <br />cell, 191-foot tower. It puts out… A cell tower’s just like a radio station. When you’re under the 21 <br />coverage of that cell tower, that radio station, that 191-foot cell tower, it essentially goes out, 22 <br />technically, out to 25-miles. It could cover everybody in a 25-mile radius, which is no (inaudible). 23 <br />Generally, in an area like Chapel Hill we’re only going to go out of like 2-miles and if you guys 24 <br />remember your algebra from high school and remember pie r squared you thought you, you 25 <br />thought you’d never use that, you get to use it today. A cell tower that goes out 2-square miles 26 <br />to… it covers 12-square miles. So a typical cell tower in like a suburban area like Chapel 27 <br />Hill/Raleigh, it’s going to cover about 12-square miles. Ok so that’s a macro cell. This is what 28 <br />we’re talking about, small cells, which is something that’s new, it’s not new, it’s something that’s 29 <br />rolling out very rapidly. It’s rapidly going to take over. A couple years from now you won’t see a 30 <br />cell tower, this will not even be an issue anymore. The cell tower’s are going from those large cell 31 <br />towers to much small cell towers. These are about the size of a Rubik cube. They’re very 32 <br />inexpensive, about $400 a piece, and generally we’re putting them on every lamppost in town. So 33 <br />instead of covering 12-square miles you’re only covering one block, but it’s got tremendous 34 <br />advantages because for number one, those little cell towers provide better coverage for smaller 35 <br />areas, obviously you need a lot more of those, sixty to cover the same area that this cell tower is. 36 <br />Overall, they’re a lot cheaper for the companies and greater service. So one of the greatest 37 <br />benefits is 911 service. When you call 911, I was one of the people who developed 911, I have 38 <br />patents in that area… when you call 911 a tall cell tower and get you to about a half a football 39 <br />field. We can locate you 65% of the time to 150-feet. That’s what we’re requiring cell towers to do. 40 <br />These new cell towers, since they’re only going to be a block, they’re going to be able to locate 41 <br />people to a matter of 50-feet. And so for a lot of reason, one for financial reasons, one for safety 42 <br />reasons, we’re all going to these smaller cells. This is going to be more efficient. And the FCC 43 <br />back 2015 just cracked up the accuracy that we need to provide for 911. And these small cells are 44 <br />lower power. The other big benefit for us, a lot of them are using an unlicensed frequency. Think 45 <br />of them as like Wi-Fi. They’re totally unlicensed. So instead of doing all the things we have to do 46 <br />for a tall tower to use the licensed frequency… It just makes life a lot easier. One of the greatest 47 <br />benefits is when you’re in a high rise. Instead of having one cell tower outside that power is 48 <br />providing coverage to everybody inside. You can put one of these small cells on every floor of a 49 <br />tall structure. And one of the greatest benefits is if someone calls 911 on the 15th floor you know 50 <br />108
