 The last challenge that we had is to provide better services without replacing the customer CP. We choose to use RF Element Horns, creating small sectors, micro sectors, and four years ago I plan to use 10 degree sectors, let's see, what we can do in the future to bring more bandwidth. Micro sector, so 10 degree sectors where I can put inside 10 no more 20 customers, micro sectors, so 30 sectors in a tower, imagine that, and I plan to do that using panel antenna that use usually the 23db panel antenna, but even like directional one, not the sector, just the direction. The panel antenna for the CP for example, the standard square 30 cm wide usually have a gain of 20-23db and the aperture vertical and horizontal is 10 degree, was perfect for my idea, but I never did because to mount the 36 panels is not easy, first, and second, because this antenna use patch array system on the printed circuit board on the PCB and the diagram, the polar diagram is not uniform, have lot of micro sector together, then one years ago I start to watch a new sector, isometric one, the 2030 from RF elements that if you mount in horizontal is 20-60db and is 15-3db, okay, is not 10 degree, but can be a starter before we are using the ubiquity sector with 30 degree on side, so we are working with 30 degree antennas, but they have not so much insulation each other, we know that, but they work for a while. Your hordes is for us 15 degrees, have a good gain is 20.5, remember, and a good elevation aperture is 22 degrees at minus 3db, is the opposite, so I am able to cover more people than the standard sector that have 8 degree or vertical aperture, and okay, the 15 degrees wide, 22 degree height is perfect to cover people under the tower and in front of the tower, let's see, and the diagram, the diagram is just one main giant loop, it's perfect. We design all the sectors, we load the antenna profile of the RF elements hordes that we was able to download from the website and we was able to upload all our customer location, these are the customers that we had attached to this tower before upgrading, that's the coverage. With this cover, for example, this one will be difficult, not this one, it's inside, so this is a different point, and most of them, everybody is inside and with good signal, see the horn shape, and we increase people from 10 megabits probably because they have some signal problems or they are in some side lobe, you know, in the patch array antenna, you will never know what happens, from 10 to 60 megabits on 20 MHz channel, and you can see we was able to increase the signals between only 6 dB, a lot 6 dB, and we will be able to switch to 40 MHz channel now because we have a good signal, we don't hear interferences between our horns and the competitors, and with 40 MHz we are able to bring up to 120 megabits to the customers using market devices, and you know, on the market there are better wireless products today with better technology.
