 So I guess we can then start with today's presentation. So today we're going to be speaking about migration to horns. So we're going to basically divide this topic into two major topics. First we're going to be speaking how to do this hybrid model between the use of previous sectors and horns. We will present a few use cases or typical let's say scenarios of deployment where you can see how the horns will benefit your actual deployment. And then we will also of course speak on the second half of this presentation about the same migration to horns but with a full 100% horns tower. So each of those we have prepared a few use cases that we will present so you can see maybe it will fit to your needs. In any case, at the end of this presentation we will have of course some dedicated time for questions. So please feel free to write to us during the presentation in case something you don't understand or you would like to clarify it even further. So let's commence with the presentation. As you can see well already Mr. Luis introduced me. My name is Jorge Fernandez. I'm the product manager at RF Elements and let's commence with the first slide of today's presentation. Just one more thing, this webinar is being recorded and also live streamed on our RF Elements page on Facebook and on the RF Elements Asia group as well. But after we finish this presentation we will edit the webinar and we will upload the final presentation as a recording to our YouTube channel which of course we will share on our different platforms. So without further ado let's commence. So why we will consider on the first glance like why we will consider migrating to horns, right? Well of course there are several let's say symptoms that your Wisp network is already experiencing indicating that commencing a migration would be a good idea. You're seeing here strong interference which brings of course unstable network throughput which also comes to jumping modulation rates erratic latency issues as well you're seeing on your screen right now or perhaps too many customer complaints. So all of this when they come together might result into more subtle results like for example your inability to grow your Wisp as a business. So your underperforming network simply will keep yourself so busy all the time that you don't have even additional time to think on how to grow your Wisp. So seeing all of these issues you might be interested to try our horn sectors we will explain a little bit in the upcoming slides. Our horn sectors they address the root cause of the problems in the unlicensed 5GHz band which is interference, sorry so because the horn sectors does not have any side lobes. So since the horns do not collect the noise in the first place and this trickles down to the majority of the problems mentioned on this slide. So which are the most typical problems when we are migrating to horns? Perhaps you're sick and tired of all the interference issues and you're ready to give the horns a chance well there can be several issues that you might run into as you want to migrate to horns, right? So that is basically as you see no general instruction on where to start or maybe the execution path is not let's say clearly defined. Perhaps the initial test you do is results they don't give you a good picture of what you're expecting or perhaps you might be confused of the horn technology let's say this way to begin with and all of this is absolutely fine whichever is your case this webinar will address all of these points. So as I said at the beginning we're going to start with two or we're going to basically expand these topics two major topics we're going to speak about how to increase the coverage which means of course the combination of the traditional sectors plus horns and then on the second part of this presentation we will see how to deploy a network with 100% horns on your towers. So before we jump it's good to know beforehand some details there are several things that we should keep in mind and understand before starting the migration itself so our horns are in the market since 2014 so these years already have created a very solid research online base so you have plenty of experiences that you might consider looking into before you start we have of course we encourage the people to find the solution to the problem they actually have so not to deploy for example a bigger degree antenna higher bandwidth in horizontal when you might need perhaps something more less wide so focus on the problem you basically need to solve what you really are facing understand the spectrum limits we understand of course that the spectrum is a limited research so we need to start to think how to use it more properly and then fourth point is this slide let's use it in a way more smart, more wise the spectrum because again it's a limited resource so eventually of course we need to understand the limits of the hardware we are using as well so we need to keep our expectations realistic so now we are going to present a series of let's say use cases where horns will be the right choice to deploy so let's see this example on your screen right now we're seeing for example four sectors let's say these sectors are for example 90 degrees patch array antennas so we are covering 360 we can see of course on the edge of the sectors that the coverage is not really the best you can see that there are some pin on the maps that are red some of them are yellow which means the connection is in a regular state so therefore you need to improve this kind of connectivity to these clients so what can we do? we can do an upgrade so we pick one of the sectors that we already have deployed we change that sector for horns we see the performance, we see how they actually bring the results or let's say positive results to your network so we see that the clients that we are being served by the horns are now having a very good signal which means that the CPs are properly modulating because the antennas of the access points they can provide a better SNR and a better noise rejection so this way for example you can pick one sector, deploy horns this is a way to basically do not commit to a major investment at the very beginning but we can test the water let's say this way first with a minimum risk level another important aspect that we can have because the horns are different from the traditional patcher ride sectors we need to know where our clients are so let's check this example on the screen you are seeing now we have clients that are connected on the back loop of the traditional patcher ride sectors because these antennas they have this enormous back loop and yes you can connect the CPs which of course will result in a very poor connection the point here is we need to know where our clients are because when we switch from these antennas this patcher ride to the horns since the horns they project the signal on the front of the antenna not on the back these clients that were connecting on the back loop of your old patcher ride sectors right now when you migrate to horns they will not have a connection so you might need to place a second antenna to serve these customers so this is just an example we chose to use a 90 degree symmetrical horn on the right side of the picture we also of course one of the points we spoke on the previous slides is that we need to have realistic expectations so we need to understand the hardware we are using the horns yes they solve the problem of noise noise and self interference through the lack of side loops once the issue of the noise is basically solved then we need to be aware that the rest of the hardware in that equation has also limitations as well so we can only expect results within those limitations so in other words the maximum aggregate throughput you can achieve is basically limited by what the radios can handle all the horns what they will basically do is they will get the best they will push the radio to the limit in order to deliver the maximum throughput possible but again the chipset of the radio itself has limitations another very important thing is we encourage people to use the antenna with the right gain so the options of the gain selection let's say that this patch of right antennas the traditional patch of right antennas they bring to us it's very limited so this leads to users basically developing the habit of using a very wide antenna or too much gain in situations that they don't need to so you are seeing for example left of in this picture the left part of course a traditional patch of right antenna we can see that all the red part is area in which we don't have customers and we are just giving too much signal too much gain, too much aperture in the horizontal being with and you can see how it's already covering areas that we don't need so this is also creating problems because it's basically capturing noise from far away solutions so we can see the difference so with one antenna on the left we provide signal to places we don't need with the antenna on the right we see that it's a very well defined shape you are projecting on the terrain itself so you are always covering what you need that's the important thing and it's one of the of course bullet points we mentioned at the beginning let's use the right antenna for the job select the antenna we actually need based on the necessities or the needs of our CPS in the terrain so let's not use a high gain antenna to cover few CPS and basically project signal far away let's use a horn antenna, let's focus the signal what we want and let's achieve a better throughput and better SNR another also thing to keep in mind is the down tilt so with the sectors, traditional sectors the down tilt is very limited what you can do and we can see again that we are projecting signal far away from the tower which we don't need now you can check the horns on the right side so that this is one of the beauties of the antennas of the horn antennas, you can tilt the antenna to basically just give coverage or give service to the people you actually need so you can see we are replacing for example let's say on the left we have a patch a raise of 90 degrees and on the right we have three antennas horn 30 degrees and you see how we are adjusting the tilt depending on the distribution of our clients on the terrain so this is another important thing to keep into consideration the antennas, the horn antennas with the down tilt will help you to optimize the coverage because we are already basically projecting into the terrain so a question can be how we can know the down tilt which down tilt I should use for one antenna specifically, ok, the reply for that is we have a link calculator on our website which you can play with the down tilt and see how the coverage will perform based on the input parameters so it's easy, just go to rflemons.com you click on link calc and then you see basically the simulation and you can play with these parameters and see how it will work the down tilt in your specific scenario, so you can basically for sure check this tool of us, it's free to use so you can plan your links and even have beforehand an idea of the performance instead of using just one antenna for a high dense sector let's analyze this in particular scenario let's say we have three sectors on the left as you can see the sectors are making noise to each other in the tower in the center in the pin you can see that these sectors are really crowded the density of course is quite high so we are going to replace these sectors for different horn antennas in order to provide a personalized coverage you can see on the right side the same basically scenario but now it's served with horn antennas in this case we chose three symmetrical horn 60 degrees antennas and four symmetrical horn 30 degrees you can see how we basically split all these patcherized sectors into smaller sectors to basically give a better service to these clients so the idea is let's use the right antenna based on the needs of the terrain because we know that CPE sometimes can be scarce in the terrain you can have many in different positions so you can choose which antenna to use based on this, again you can use the link calculator to try out which antenna will be the one you should use based on your specific needs now with our filaments you have what we call a tool set, so you have seven antennas symmetrical horns, three asymmetrical and one ultra horn which of course complements everything to give a personalized coverage based on your needs now balance and network is very important of course to keep the customers happy to keep the connections in a very, let's say, good condition so we're seeing here again we start with a use case, we start with traditional sectors, you can see that basically in the center of the sector you have the best coverage but once the CPEs are located in different areas of that coverage of that sector, sorry, you can see how the MCS starts to drop this is a typical, let's say feature of this patch of antennas that you have the best connection in the center and around the areas or in the borders the connections are dropping so we can see also of course the network throughput is really not the best but if you download it's quite high so what we can do well, okay, let's apply a different approach here let's put a horn antenna which again provides stable coverage, well defined radiation pattern with the coverage on the terrain will be also defined and we can calculate and see what we can expect so with the antennas, since the horn antennas the MCS rate will be very stable across all the CPEs and this is one of the features of course of this type of antenna with the symmetrical beam pattern as well so we can see that we replace this horn this patcherite sector with horn antenna we can see now that the CPU load is lower and that the network throughput is higher so of course this is something very positive and it brings us even the possibility of increasing the amount of speed that we actually provide to the customers so let's understand a little bit what is the symmetrical beam of one antenna our customers are sometimes confused with these symmetrical beams patterns of the horns you can see a difference the vertical or the elevation plane being with is very narrow so it's typically few degrees as we can see on the symmetrical horn antennas that it's basically more wide I mean symmetrical means of course the same aperture either on horizontal or vertical planes so this of course has a number of benefits for the deployment of horns to several types of landscapes for example even if it is a high customer scenario density scenario or deep valleys of course they work really well because of the shape of the radiation pattern you can see clearly the difference the patcherite has a very wide aperture in the horizontal plane very narrow aperture in the elevation plane you can see how the symmetrical horn is basically projected horizontal and vertical is exactly the same aperture in degrees now the asymmetrical is a combination it's like we get the symmetrical horn and we squeeze it from the top so we find the asymmetrical horn we can see that the asymmetrical horn they have a narrower beam within the elevation plane it's very good for deployment for example for rural deployments where the clients are far away from the tower but far away in between them as well so the shape of the radiation pattern of these asymmetrical horns is very good for this kind of rural deployment CPs that are far away from the tower and of course with distance between them also quite high so we can see how it looks beam switch the 30 degrees now we're seeing the 60 degrees 60 in horizontal and 25 in vertical and we can see now the asymmetrical 90 is 90 horizontal and 25 on vertical now how can we go or how we can do this increasing the coverage on our X16 network now there are several approaches that we could apply to this of course maybe some people would like to start for example testing the horn antennas to see how they perform by offloading these access points which are really crowded or perhaps extending the capacity of this tower so once you have decided which antenna or you want to use of our filaments well it's smart to consider also which are the necessary ones for the thing you need to complete again we go back and we make emphasis in choosing the right antenna for the job so not more being with that we need focus the radiation pattern where we want to provide the best conditions for a proper link to the CPEs so now you know that you have in your hands the tool set of horns so you have 10 different tools to choose from for example smaller horns for close clients larger horns let's say in gain for like higher capacity or perhaps even distance so if you also want to have the option of providing more speed to your customers like higher packages for premium customers well there is no problem with this the horns will enable you to increase this speed of the customers as well so there are several of bullet points in these slides that we will expand each one of them to explain how you can achieve the completion basically of each one of these so let's start with the first one what is when we speak about of loading or adding capacity so let's say we have four sectors say randomly 90 degree sectors you see that there are two sectors which are really crowded so the throughput is really not the best because the traditional sectors are really incapable of providing this speed to your customers because of the side loops and all the noise issues so let's apply one horn to each of those overcrowded sectors so we can upload CPs from the main sector antennas to the horn antennas therefore we split somehow the CPs and you can see now that the performance is way better we can use the smaller wider horns for close clients let's look at this typical scenario we have a sector we have a bunch of customers at the very close to the tower and they are really suffering because of the poor connectivity with the sectors ok well let's leave this sector already in place and let's add another sector in this case we choose 90 degrees one symmetrical and you can see that now you are releasing these customers from the main access point but you are also giving them a better coverage because you are having a horn tilted for their specific deployment right on the terrain the same goes basically with the larger or narrower with horns for high density scenarios again we have a sector one portion of this sector is crowded so we are going to basically provide a service we will put a horn antenna dedicated for those customers and we are going again to afloat them from the main access point and also give them a service that is better in quality and even in speeds as well depends on what we want to provide how to achieve the higher throughput packages with horns well again we start from the scratch that we have a sector but in that sector we have let's say four clients and these four clients are let's say businesses so for the nature of what they do they will need increased bandwidth because they require so right so what we are going to do is we are going to separate these customers who require very high bandwidth or speeds from the main access point and we will assign a horn to provide them the coverage they need therefore we are going of course to provide be able to supply the needs for speed they have at this point how to improve the edges or the borders let's say this way of the typical patcherized sectors well you are seeing here your screen there are CPEs in red that are in the borders of two sectors therefore of course their connectivity is very bad they have poor signal lower SNR so what we are going to do in this case is ok let's put a horn in between those two sectors and we are going to give a proper service to all of those clients and therefore also releasing them from the main access point improving of course the main access point improving them since they were really in a bad shape of connectivity and you can see that basically it's a win-win scenario right so the sectors are not the end game let's say this way because this will require more channels so on the left side you will need basically 5 channels like you have 4 sectors, 4 channels 1 channel for all the 4 horns now if we replace everything for horns you can see that we will only need 2 frequencies so we will be saving 3 frequencies therefore we will be of course also improving or helping or contributing to improve the local spectrum where we are operating in a specific area so you can see that with horns this is completely able to be done the second part of the webinar as I mentioned at the beginning is let's talk about how to build a brand new tower with 100% horn so there are different ideas, different approaches, you can start with a combination of symmetrical and asymmetrical depending of the let's say the cps where they are located or the terrain, the ground, if it is a valley area, suburban or urban you will choose so you can start playing with our toolset of course to give a proper coverage you can see one of the examples is uniform coverage custom coverage based on the customer layout and the last one is basically add or swap horns as needed so let's see a little bit of each one of these now the uniform coverage I think that the term itself is already very clear so we will start basically covering 360 degrees with pure horns you can see we started for example with 6 horns of 60 degrees but then the density just went up because we were able to provide a quality service to those end customers so now 6 is not enough, we need to replace those 660 for 1230s so density grew, business grew income of course therefore grew as well we were able to provide a good connectivity customers are happy density is growing so it's good for business therefore we need to increase the density so you can use narrower being with horns the custom well it's basically provide coverage where personalized coverage depending on the cps in the terrain so this is a very let's say example we can combine as it says here various degrees of horns depending on the coverage we want to do of course depending on how the cps are located in the terrain another and the last point is how to add and change horns needed so we started 4 horns 90 degrees let's say this way but one of the sectors got so well the clients were so happy we started to increase the amount of clients density grew so we started to replace those 90s for 30s so you can see how we can play so the tool set brings you this opportunity to play with the coverage you can swap you can add here you can get a 60 degree sector and put 230 so you can get a 90 degree sector and put 140, 150 degree horn you can play availability that basically the possibility of playing which with the traditional sectors is not possible like density with horns is super achievable you can get it you can get high amount of cps and you can get all of them served properly by using the horn antennas so I guess maybe you are wondering now how densely I can install the horns for I guess this picture in the screen is already saying to you like many horns all of them working perfectly coexisting together many sectors with excellent and stable performance right so this with horns is a daily reality and keep into consideration that this is our customers pictures not ours so what a few advices we have for you before we wrap up this presentation so use the correct gain of the horn for the required coverage so select the right antenna for the job know where your customers are before deploying very important use the down tilt if you need it to achieve different goals the hybrid antenna solution is not the best approach and very important plan before you deploy successful planning can bring of course successful deployment so it's very important that we see it before we use all the tools we use the data cheats with analyze what we have what we want we make a strategy of roadmap and then we started basically deploying so it's very important to plan ahead where to buy a product we have a store locator and a web page that you can check which product you want and region and will definitely tell you with which distributor is available with this product how far antennas go we already mentioned this before link calculator on our website you can click on it and you can start simulating your links how to become a distributor there is a link at the very end of our web page you can see it here on the image you tap on become a distributor you feel all the information that is there and we will contact you we have communities on Facebook our filaments English our filaments Asia in this group as well which we are sharing this live stream right now and we have of course a forum RFELab where you can also register it's free completely free for use and you can basically communicate with us through that as well we have a playlist on our YouTube channel named Wisp Traveler in which you can see how other people have been migrating their towers to our filaments horns and how it has been the results so it's also another way for you another source of information for you to consult we have of course also the educational videos of the inside wireless this is a very short videos 2-3 minutes with a lot of information presented to you in a way in a very dynamic way that you can easily understand has very topics of our filaments sorry RF engineering so if you are if you want to know a little bit more about these important parameters and explanation we invite you to go to YouTube search for the inside wireless playlist on our channel our filaments and you can of course see them alright well on my end this is all I have for you guys today I want to thank you all the attendees on our social media and on here and also Luis thank you so much for being with us the recording will be published in the coming days and we will of course everything will be posted on our social media so on my end this is everything thank you very much and have a great day
