 Hi guys, I'm Luis of i2warehouse, we're the sole distributor of RF Elements here in the Philippines and Aside from RF Elements, we carry other brands like Microtik, Youpequik Team, PeopleLink, Comfast and many others. You can talk to us on our Facebook page and Our Lazada and Shopee stores. I'll link it somewhere here Now Everyone likes value for money also known as bound for your buck and that's one of the main reasons Why we believe in RF Elements? Why we applied for a distributorship for their items? A lot of products from a lot of other brands work. Yes, but RF Elements products They offer so much more. You get so much more in the long term. You get reliability, co-location, customizability and durability All these characteristics you can put into one word which is future proof Now, I'm sure you'll learn all about this later, but I guess my point is this As business people and as humans, we have the responsibility to look as far forward into the future as we can And right now, I'm sure you're all aware that there's a problem with RF toys with spectrum with reliability and all that and it will only get worse RF Elements helps prevent that Now Enjoy the webinar and I hope we'll all learn something today I hope that you find the value in RF Elements like we at Highity Warehouse do Now some words from my fellow Filipinos Hi guys, and I'm at the park at 10. Enjoy it. Of course, you won't be able to ask questions in the Q&A And then join us guys in our Facebook group RF Elements Asia and RF Elements Philippines. They are there Our speaker right now is RF Elements in Slovakia And he's also in Trident Networks of Evil. Check it out guys. And that's all Again, enjoy and thank you. All right. So Thank you. The ones who confirm that the presentation is properly shared with you on your screen and I once again thank everyone who joined us today So first of all, as you're seeing here on the screen My name is Jorge I am product manager at RF Elements and today we will be Presenting a very interesting topic About noise reaction basically How we deal with this? What is our approach? How? You can make your Wisp Thrive your Wisp grow with RF Elements antennas by rejecting noise So without further delay once again, good morning to the people who are joining and thank you very much for being with us today So let's uh comments with the first slide of this Of today's presentation. So at RF Elements We have a main goal which is to help the Wisp grow or thrive by Enabling them to run stable and fast wireless networks through our noise rejection technology With near zero loss radio connection The noise reaction Is a stepping stone towards massive scalability of wireless networks provided by our wide range of antennas I'm very sure that you have seen this kind of spectrum analysis, perhaps in your local deployment areas therefore The number one challenge that wisps are facing today Is the that of RF noise in the on-license on-license spectrum, right? so wisps commonly see Spectral graphs with high to very high noise floor That prevents the wireless networks from optimal functioning And sometimes even to the point of giving up on the on-license spectrum and the business all together As we know the spectrum is quite limited and therefore Should be preserved as one of the most valuable resources in on-license Wisp networks The main cause of the spectrum congestion Is the huge amount of wireless devices deployed The very advantage of these on-license frequency bands became one of its main Downsides and on top of that these devices are Based on technology directly adopted from other industries, which is unfortunate because the Pacha Rai antennas are completely unsuitable for Wisp on-license networks So the main issue here is the antenna side loops Which are almost never mentioned when talking about antennas People usually talk about gain. They talk about being with And perhaps even from front to back ratio, right as parameters commonly discussed But people don't usually speak about the side loops, which are the root cause of the problems with noise in on-license Wisp networks There for example this case, right Of the directional antenna This is an antenna that it radiates equally in all directions in the azimuth plane And nothing in the vertical directions making the radiation pattern kind of like a donut, right So omnis are the least suitable antennas in on-license bands Since they spread the signal everywhere and receive it from anywhere. So Basically, it's a full 360 degrees circle Now for the vast majority of scenarios The wisps deal with is probably the worst antenna since it pollutes The spectrum in every direction and makes any network Extremely sensitive to any noise sources in the area, right Now, uh, Pacha Rai antennas Cover a sector right a slice Let's say this way of this whole asomith azimuth circle of the 300 of the omnidirectional antenna So a typical radiation pattern of a Pacha Rai Our antenna looks like the one you're seeing your screen nevertheless The side loops despite being quite a bit smaller than the main loop They still cause problems with the noise and on top of that the size of the side loops And therefore the performance of the antenna Changes with the frequency which is extremely undesirable feature, right The frequency dependence of the radiation pattern causes the RF radio will see different spectrum. So you cannot reliably trust That you'll see the same performance when you switch the channel This makes this kind of antennas or the networks that are based On a Pacha Rai antennas like a house of cards Because even the slightest change can throw the whole network off making your life quite difficult These antennas are commonly used for point-to-point deployments. They also have many side loops as you can see in the animation The physics of these antennas dictate that you cannot fully avoid the side loops So the result is of of having one of these antennas Uh, it's basically the same as with a Pacha Rai sectors, right huge amount of side loops And these side loops they collect and transmit noise from unwanted directions eventually Showing up as a slow network leaving you scratching your head wondering Where is the promised, let's say a gigabit throughput that the radio manufacturer declares on their data sheet The problem with side loops Uh causing high noise levels in whisper networks multiplies When we introduce more sectors, right? So the side loops of the neighboring sectors interact with each other and despite all devices on a tower might be your own devices Uh, and let's not even count the potential competitive whisper networks So despite all of these devices can be yours the interference problems keep growing until you hit a limit We're adding even more Or even one more sector can make the whole network completely dysfunctional The same is valid for for back holes links regardless if you use addition antennas or a directional Pacha Rai antenna the side loops of these antennas, uh, that the side loops they have are inevitably Will lead to consistent degradation of the wireless network throughput and even more In the case of unlicensed 5 gigahertz networks where your competitors use the same antennas or the same type of antennas as you So what is the solution then? Well, let's use right, uh antennas without side loops and uh the beam uh beef the beam width that we need Feeding the coverage scenario is the true solution to the problem of interference because when you don't collect the noise You don't have to deal with it. And if you only cover the area necessary, you're doing the best thing you can do for your customer's satisfaction So let's take this example one more time If you replace even one Pacha Rai sector with a horn antenna You will see how horns really work, right? You will see significant change in the performance Not only the horn sectors will perform very well, but also the Pacha Rai sectors or the remaining Pacha Rai sectors will improve and this is counterintuitive and sometimes confusing thing about horns, right? They provide better performance because they lack something and in this case they lack side loops But we can go even further taking the same example and let's replace the whole network with horns uh because the biggest gains uh of the Total network throughput and stability are visible when all Pacha Rai's are removed and are replaced by horn sectors, right? So we remove all the Pacha Rai's we remove all sources of noise So we will stop worrying every day about For example, let's let's not touch anything so that the network doesn't crash and switch to wow I have little to no noise And I can still keep adding customers with no problem This is a real possibility within the within your reach with the horn antennas Taking the point-to-point example Replacing also the dish antenna with a highly directional horn antenna in high-nose areas The overall throughput will increase and you'll introduce huge stability to the network the modulation rates will not only be high But they will also be consistent so Horn based point-to-point links are very stable. That is how the horn antennas work Unlike the traditional Pacha Rai sectors or ditches Now the real magic here happens When we only use horns in our point-to-point links this case, right? So no silo equals no noise equals maximum performance, right? and also happens that sometimes the wisps who are Who start to use horns are very happy with them and they want to keep these two themselves, right? They don't want to share The what they found out that works for them And because they think that this is an advantage over their competitors The fact is though that if your competitors also use horns as well It will be good for you because the less noise everyone generates Our overall result is the better, right? If you wonder how you know, we can install the the horns how densely Horns can be installed in one tower We believe that these pictures speak out, right? Basically, it's many Many sectors co-existing on one tower and with excellent and stable performance at the same time, right? Which is very unbelievable because with horns. This is a daily reality and and please take into consideration that These pictures are from our customers. They're not our own pictures, right? Now horns Are the toolset that allows you to respond and adjust your network to any situation? Optimally, right? So on the left side And on the right side, you can see a group of ultra horns antennas, right? They are covering Distant narrow sectors with 15 degrees being width and each antenna is covering one sector In a specific area so in the middle We can see a cluster of different being width horns, right? So the versatility of scenarios you're able to cover with horns is practically unmatched You can really sense why we have seven different symmetrical and three different asymmetrical horns, right? Plus a high gain narrow beam being with ultra horn Um, basically the variety of the gain allows you to plan your network depending on what you actually need Because every situation is asking for a specific tool, right? Every every Zone or every area of deployment can be different from the other. So For example, if we have a dense customer base close to the site, you know, a low gain horn should be used If we have a group of customers Clustered far from the site or then ultra horn would be the way to go because has a high gain In a narrow beam So for every, uh situation, you know, we have A tool for it. You have the uh variety of horns to choose from to deliver the customers Quality service that they can rely and you don't have to constantly worry about If you want to know more about our Basically all of our product portfolio or antennas, including the adapters Uh that you need to to use with the radios different radios for a wisp networks Please check the recording of our product introduction webinar on our youtube channel In the recorded webinars playlist We have also a link calculator This one you can use you see how is the interface you can plan your links You can introduce all the data the more accurate the better and you can basically see how the performance will look like So we encourage everyone to please go ahead enter our website our flamans.com Go to the calculator plan your link see what expected results you can get and that's a very good starting point To you know consider before you even buy any of the products Now adjusting the transmission area uh wisps commonly use The radio output power adjustment to control the coverage area and in this way They also control the amount of noise transmitted to any neighborhood neighboring links, right? Which makes perfect sense and helps with the noise That a given link produces but as you can see Decreasing the output power of the radio does nothing to the noise received by the access point from other competitive Links and this is an important point to understand, right? That adjusting the radio output power will only get you limited improvement To deal with the noise in a more efficient way You need to adjust the reception area as well by using an antenna with lower gain doing that Then well the reception area basically shrinks becomes smaller Which mitigates the noise the access point sees and this is another Strength of the horns, right? We offer as well low gain horns As well as high gain horns, so you can react right and accommodate To the surrounding interference situation Adequately and optimize the performance of your network So far We have talked about, you know an antenna have a lot of silos doesn't have silos or This kind of topic of terms, right? But this can sound rather vague We might wonder, okay, you know Is there actually an antenna parameter that can give us a quantitative measure Of the amount of silos an antenna have well Yes, and the answer is basically a beam efficiency Beam efficiency is an antenna parameter that again Quantifies the amount of silos. So What is it? Well, beam efficiency is the ratio of the main low energy to the total energy an antenna radiates So maximum beam efficiency you can achieve is 100 percent In this case, it means the antenna has zero silos, right? So 100 percent of the energy that the antenna is radiating It's in the main lobe, which is of course what we want it to be Now the closer the beam efficiency to zero percent is The more silos an antenna has Practical example here is a radiation pattern of a generic parabolic dish You can see the beam efficiency is 40 percent This means that 40 percent of the energy is contained in the main lobe 60 percent of the energy is wasted and it's going everywhere else So basically these are the silos, right? With the beam efficiency the comparison of antennas in terms of silo performance You know becomes extremely simple because the higher the number Wins, right? So ultra horn here as you can see has 99 percent again meaning 1 percent is wasted Versus Genetic parabolic dish antenna has 40 percent beam which have been With right be a beam efficiency, sorry and it means then that The antenna is only using 40 percent of this energy in the main lobe and is wasting which is silos 60 percent of the energy, right? Which is in this case a huge amount in this case 99 percent versus 40 percent I mean is clear that the ultra horn is better antenna in terms of noise suppression and probably the best on the market and here's an example of Different antennas from the market. You can see antennas that are used for Coverage sector coverage in wisp networks. You can see basically our patch array antennas or horns You can see that the values of the beam efficiency Are around 60 percent Of course it depends on the manufacturer and design quality now The thing to notice here is that the RF elements horns In this case Both the symmetrical and asymmetrical Have a beam efficiency around 90 to 95 percent So you can compare basically all the horns in the market versus our horns. I guess the Basically is clear and the king of all is the ultra horn with just 99 percent, right? That's the best antenna in terms of noise suppression in the market Same goes for the point-to-point antennas Point-to-point antennas Some of them also use the patch array design, right? And we can see basically they are at the very bottom. Then we can see ultra dishes And you know ultra dish here behaves a little bit better Generally the bigger the dish the better the beam efficiency is but again, it will depend on the Design and manufacturing quality again notice the ultra horn is really The best performing antenna on the market in terms of noise suppression has 99 percent beam efficiency Now if you want to see all the beam efficiency numbers or You know values for each of our antennas you can download the data sheet in In our website and you can see that This number is printed that right so We encourage you to Look at this if you really want to know Now there are three rules of successful noise rejection. First of all use high beam efficiency antennas You know the higher the beam efficiency The less the silos the lower the noise floor and eventually higher network throughput Secondly choose the right beam width and gain for the job We offer the wide selection of horns with different beam width which makes it very easy to pick and Use the right antenna for the job right and the last one Adjust the gain of the access point antenna to the scenario right the adjustment of the radio output power has only very limited result and We also have community RFE lab You can enter there and register At this forum is where you can ask anything about our antennas or perhaps you want to search through the questions That other people ask in the past So anyways, you can register here for free You can here's the link rfe lab.com and we we're looking forward to interacting with you We have a youtube channel called RF elements inside of it We have a playlist called wisp traveler where wisps like yourself talk about their experience with horns Like what problems they were facing how horns helped them deal with these problems So we have customers from all over the world So I encourage you to check out your fellow wisps how they're using the horn antennas another playlist In our youtube channel is inside wireless.
