Wireless Livestreaming Over Long Distances

hello there in this video we're going to explore how to create long distance wireless uplink for live streaming video to YouTube are the platforms so you might find yourself out here in the middle of nowhere just somewhere where you can't get a reliable wyott Ethernet connection to a camera or your broadcasting rig and sometimes you might be able to use cellular data but often that won't cut it as well because of the low upstream bandwidth available so what do you do we're going to use two of these to create a high bandwidth wireless uplink that we can transmit our live stream true now you can use these to create a link of say just 50 meters or less if you need to but right now I've got one set up here and one set up of the silo out there in the distance and that's actually about seven hundred meters away so we're going to see how to set it all up and get a live stream going from here and up to the internet connection I have up there seven hundred meters away let's go now the unit itself here is an integrated radio and high performance directional antenna all-in-one so I've already got this one set up to connect to the other one I've got up there on the silo but later in the video I'll show you how to do the configuration so you have a matching pair that you can just set up and use right now we're going to take a look at how to wire it all up and get it connected to your camera and your computer ok so the first thing you want to do is plug in an Ethernet cable into the radio so we can get the network connection that we get from the wireless link into a camera and into a computer and we're going to plug in the other end of this cable into a switch and I've brought an Ethernet switch with me here that will allow me to connect both my computer and the camera to the network connection I'm getting from the radio so what I'm going to do is I'll just plug in the other end of the cable right here and this which actually has the added benefit that it will that's going to power up the radio as well so I don't need a separate power break it's sending the power out over the ethernet cable and the radio supports that that's really really nice in handy so that's one device plugged in and now we're just going to plug in the the camera and the computer to these two other poles right here and we're about ready to go okay so we have both the camera the radio and the computer all connected together through the Ethernet switch and I'm just going to log into the web interface of the radio right now so we can see how good the connection quality is so I've locked into the web interface here and we can see that the radio has actually already synced up with the radio and the other end they are connected and right now we have a link capacity of about 140 megabits per second so that looks like it's going to be plenty for us to send a live stream and I always recommend that you did you go and do a speed test so you also test out the actual internet connection speed because this is obviously only D is the speed of the link between this radio and the radio and the other end so the internet connection speed might vary as well and you should definitely check out that before you start transmitting now it is very important to keep in mind that these antennas are extremely directional so it's very important to get them aligned perfectly towards the antenna and the other end and that might seem a little bit complicated but it's actually quite easy because there's some really good tools built directly into the radio software that will help you achieve this easily and I'll also show you later in the video how to use those tools alright so we've got an uplink oven running we have our camera powered on the computer is connected and everything is ready so let's get the stream set up and start streaming to YouTube so I'll start up the Institute 360 pro control software and my computer here and I'm going to type in the IP address of the camera on the network and you can always see that on the little display on the camera okay so I've already pasted in the parameters for streaming to YouTube here and set the settings as I want them so let's just go ahead and start sending some data and we should be able to see YouTube's receiving the states in a few seconds so let's jump over to the YouTube streaming control panel and see what's going on so we can see that YouTube is receiving data and we have a good quality stream here 20 megabits per second so let's just start up the stream and it'll be live on YouTube brilliant so with the livestream oven running I'm going to head back indoors and we're going to take a look at how to configure two of these as a pair so you can just connect them and have a link between two of these radios let's go take a look at it the radios I've been using in this setup are the ubiquity networks nano beam AC radios ubiquitin networks produces a lot of different radios and antenna systems and there are hundreds of valid combinations you can use for different situations here we're going to use two of these Nano beam radios to create a general purpose and really good all-round setup that you can use in a lot of different situations and I'll leave links down in the description to all of the gear that I used in this video before we start configuring the radios let's quickly recap what we're doing we're creating a setup where we get a wired internet connection and plug this into one of our radios we'll call this radio the access point the internet connection is going to be transmitted wirelessly to another radio closer to our equipment we'll call this the station an Ethernet switch connects the station to all the equipment we need like cameras and computers furthermore we're going to configure the station to create an isolated network force so people on the other end of the wireless link can't access our cameras and computers that's the basic overview so let's get started configuring the radios first I'm going to log in to the web interface of the first radio and kinda want to select the country that um and so we're getting a warning that we're using the default password and we might as well change that now so let's hop in the password and I'll just go ahead and grab a random password that I've generated and paste that in so we're going to set up this first radio as the access point and that means that this is the radio we're going to plug in to wherever we're getting the internet connection from so to do that let's go to settings and we're already on the wireless tab right here and the first thing I want to do is go up here and set it to access point PTP and that means that this is going to act as an access point in point now if you had multiple radios that you wanted to connect to the same access point you would choose access point P TMP so that is part to multi-point and that would allow you to connect multiple radios up to the same access point here but for now we're just going to keep it simple and stay in point to point mode so that is what we're going to choose and you'll want to select an SSID for your network here it doesn't really matter what you choose but I'm just going to type in one here so the next setting up here is D channel width and this is actually a really important setting you can see that we have a variety of different options to choose from here and you might intuitively think that going with a high channel width of 80 megahertz would be a good idea because you wouldn't be able to stuff more data through that channel but in most cases it's actually much better to go with a low channel width because it will give you a much more stable communication link and you will still be able to get plenty of data true so unless you really really know what you're doing and you have a very ideal I of environment don't go anywhere about 40 megahertz actually I would recommend you go with 20 megahertz or 10 metres in some circumstances it's much better to have a very stable link than one that might give you a lot of true but sometimes but a lot of fluctuations and paths through good and other times for doing live-streaming it's really important to have a very stable link so drop that channel width down as low as you can where you still get the amount of capacity on the link that you need and for most cases at 20 megahertz channel width will be plenty to even get a 30 megabit per second stream going so start out with a 20 megahertz channel is probably going to be plenty if you can drop it down to 10 megahertz even and you'll get a more stable link but start with 20 that's a good starting point these two next options allow for some advanced tweaking of the channel parameters and we're not going to worry about that for now so let's just have a look over here where you can set the output power of the radio and this is something you want to do as well I can't give you an exact number for what you should set this to but again you set it as low as possible and you can see that in most cases we can go all the way up to 17 dB and for short links and here I mean links that are under a kilometer you should probably drop this way down actually these radios are designed to do links of tens of kilometers so this output is very high and if you go with such a high output on a short link you risk just overloading the radio and you'll just get a lot of distortion and you'll actually get a worse signal so drop this down to something sensible you can probably start out at around 9 or 8 DBM if you have a shortening and see how the signal reception on your radios are you can then adjust it up or down from there but 8 DBM is probably a good place to start on a short link and there's one more option here that might be worth changing and that is the max transmission data rate the radios will always try to use the highest modulation rate they came to get the highest speed of the link but sometimes you might find the radio trying to go with a little higher modulation rate that is actually feasible in the environment you are in and in that case you might want to manually lock it down a step again to make sure that you have a more stable channel so often you might even want to consider just setting this to 64 km from the start so all of the basic parameters out of the way we obviously want to enable encryption on the link so no one else can just connect and miss with our network and I'm just going to paste in another random key I've generated here and that is actually all of the wireless parameters that we need to change to get the access point up and running next we're going to go over here to the network section and make sure that these settings are set correctly for our purposes now you can operate these radios in a variety of different Network modes but for the access point we're going to stick with the bridge configuration here and that means that whatever is coming in on the Ethernet cable plugged into the radio will just get transmitted out over the wireless link and that is what we want we want to just transport that internet connection we're getting to the radio and the other end so leave this at bridge mode and you can optionally change the IP address of the radio down here if you want to give it a new address for management and stuff like that I'm not going to mess with that right now I'm actually just going to save these changes and at the same time with disabling the management radio so other people can not log in and change the settings in this radio so let's go ahead and do that is just going to reconfigure itself now and that is actually all there is to this heaps of other settings you can change in here there's lots of things that these radios can do I'm not going to go into details with that right now we're just going to stick with the basics so while this radio is applying the changes we're going to jump over to the next one and configure it as a station to connect to this one and we are almost ready to go okay so here we are I have already locked into the second radio here and we're going to configure this to connect up to the access point radio that we just configured so let's just go ahead and go into settings here and we can set this to station p2p is actually already set and you can actually click the select button to have the radio scan for the SSID you created earlier and you can select it from a list of all the wireless networks that it finds but I'm just going to manually type it in right here that and we're going to paste in the encryption key that we specified and actually I'm going to drop the transmit power way down to minus 40 p.m. because I have these two radios sitting more or less right next to each other right now so we're going to drop it down as far as and I'm also going to lock this to 64 crane and that's actually all that we need to do here now if you had configured the access point radio to use a 10 megahertz channel you would have to manually go in here and specify this 10 megahertz because right now it's set to auto select between 2040 or 80 megahertz so just leave it at that if you configured your access point for 20 megahertz now we're going to do the network configuration for this radio a little bit differently than the first we configured the access point radio as a bridge so it was just retransmit everything that came in over the ethernet cable to the other side of the link but we want to create an isolated network here for our computer and our cameras so that we won't have anyone on the outside of this network being able to come in and miss with the camera or the computer or anything so here I'm actually going to select router and what this will do is make the radio operate as a totally normal internet router and we'll be able to give our IP addresses to on your side of the network and to provide Internet access to all state equipment so there's a few things we want to configure first of all we want to enable net that is what will enable all the equipment on the inside of the network to actually gain internet access apart from that we want to make sure that the wall network settings are configured according to the type of internet connection you're getting and mostly you'll just need to leave the set of DHCP if you have a static or pppoe connection you'll probably know what that is on how to configure it so if you don't know leave it at DHCP I'll probably will work apart from that we're just going to do a little bit of configuration for your side of the network so here we want to specify an IP range that your equipment will operate in and the IP address right here is a very common IP range that a lot of Internet routers are using for the internal networks so to make sure that we're not getting any conflicts with the network on the other side of the wireless bridge we'll just change this to a network that is a little bit less common so we could just go with something like one ninety two dot one sixty eight dot one fifty-five fix for example there's lots of possibilities here so this is just an example wouldn't data set up we're going to enable the routers DHCP server so that equipment on our side of the network will automatically get an IP address and be connected to the Internet the interface should also configure all of these fields so you actually don't have to change anything here just make sure that UPP is disabled unless you know what you're doing and you really need it and that's actually all we need for now so let's go ahead and save these changes but remember we are also changing the IP address of the radio here so if you have to log back into the management interface you're going to use this new address right here so let's save the changes and see if this radio connects up to the access point that we just configured earlier okay the change is being applied and we should be able to log into the new IP address in just a second all right the radio is back online and we're just going to log in and we can see that the radio has connected to the access point we have a stable connection and everything is looking good so we have a wireless link going between these two radios and that is actually all there is to it is really simple to get a basic wireless link like this going and you can now use these two radios to create long distance wireless uplink for your equipment so I'm going to go ahead and a few more tips to get a good connection quality first of all let's have a look at the antenna alignment tool right here this is really really helpful when you're trying to align your antennas to a radio that's far away and you can see there's actually two antenna chains inside of the radio now what you want to do is to get the signal levels of these two chains as close to each other as possible generally you'll want to have it within 2 or 3 dB it's not always possible to get it that close but the closer you can get the signal levels the better the quality of your links will be so definitely do pay attention to this the second tool I want to show you is the a view tool this is a great tool for having a look at how congested or utilized the wireless spectrum is so you can see here that we have all of the frequencies that the radio is able to operate in list it out from left to right and down here is a so-called waterfall view that will show you the amount of radio communication on all of these various channels over time so the bottom part of the waterfall view here is right now and this is a little bit in the past and you can get a pretty good overview of where there is traffic and where there's clean channels just by looking at this waterfall view you can see that all of the blue places are relatively free of interference and traffic so while you might let the radio just also select the channel like we configured it to do right now you can actually take a look at this waterfall view and find a channel that is free about the traffic and go in the wireless settings and manually choose that channel other than that you can also get a more clear view of how clean the quality of your wireless signal is by going into the constellation 2 this will show you two so-called constellation diagrams and what you ideally want to see here is these darts clustered as close together as possible in all of the dots here in the grids are spread out really far that means that your signal is not as good as it should be for operating at the modulation rate you're currently running at in that case you might want to look at reducing obstacles between the two radios or if you can't do that you'll have to drop your modulation rate down even further to get a tight constellation diagram it's really important for a high quality stable link to have a good tight constellation diagram yes so also don't miss this it's a great step to actually verify that the quality of your link is up to the standard that you need there's also a built-in speed test that you can use to test the speed between the two radios just keep in mind that this will not test the actual internet connection speed you should use an external tool like speedtest.net for that but it's really good to also test that you can actually push a lot of data through the wireless link before you start doing that so as you can see there's plenty of tools built into these radios that will help you get a really good connection going and I know this has been a lot of information and maybe it seems a little bit daunting at first but once you try it out and get the hang of it it's really quite easy to get a basic good quality link set up and you can use these in so many situations to make your life so much easier when you're doing live streams so I hope you enjoyed this I hope you learned something and if you have any question let me know down in the comments I'll try to answer everything as good as I can thanks a lot have a great time bye
