 Okay, what's a lot of time thing? I'm sorry. Today I want to introduce you to CubeSat satellite. Everyone, every certain people heard about this. What is CubeSat? I will show you this. It's a Cubic. It's based on Cubic. So when you fly over the space, just that small. So you can have your embedded system, including onboard computer. And ADCS is an auto tilt adjustment control system. I will show you some of these problems like this. It's an onboard computer. It will mount in this Cubic structure. Also, we have ADCS because it can adjust the CubeSat attitude. Because when the CubeSat is deployed on the outer space, it will be auto-controlled. So based on the, you know, the Earth has a magnetic field. So we will use the top. You will see the X axis and the Z axis. And in the back in the back, we will have an air coil. So it will be the three axis, SYZ axis. To be the best to control the CubicSat out of foundry. But follow the magnetic field. Finally, it will be stable. And follow the field from the Earth. Okay. How do you see this? Since the video is out of focus, I will show you the EPS system. Our CubeSat name is Why You Set. Because I come from Taiwan. So the highest mountain is called Yuzan. So we have the CubeSat is Yuzan. The final date will be launched. It will be 2019. So we are now doing this project. You can see the, our EPS, the power system for the power from solar cells. And you are doing the energy harvesting. Also, you will see that OVC is, I mean, on-board computer. And the ADC is just an altitude determination and control system. So you, I just introduce you. Depending on these ADCs, you can control your attitude in the space. So this is our PCB layout and the circuit. So you will see the X axis, V axis. And the background, you will see the Y axis. So at the end, the topics will be three. Because my topic is talking about SDRT for the IoT QB communication. You know, we know many kinds of businesses are going. About the 4G in the outer space, SIGFAST in space. Everyone is doing that there. So why we are doing the 4G LOT on outer space? Because we all know 4G LOT has a feature, it's a money hop. So the constellation will be the core in our nature. Okay, the first I just want to introduce you. Because not everyone knows about the LOT. So I will simplify it. Let you know what is LOT. So you can see the 1G, 2G, 3G, 4G. The progress is about this. So everything is about packing. IP, that's the best for 4G using. You can see the progress speed is about 1G, 1G gigabytes. So you will know, in our system, the 4G LOT, we will use the 4G LOT advanced version. For our ground station and QB, mounted in our QB set. The data array is about LOT of R8. The bandwidth is about 20 MHz. And the modulation is using the 16 QAN and 64 QAN. The evolution of UMTS. You will see, you will hear about what is, maybe what he is talking about. 3G, PPP, R10, R11, R12 and R13. You will hear about LOT. Because this year, they have SIGFAST, LORA and MPLT. So MPLT is based on, the new sequence are 13. So you will see. But my cell life, we are using non-land advanced. We were using the release 9 or release 10. Because we want a stable and the communication speed is our basic. So you will see, the LOT world map is very, everyone is using it. But everyone is forgetting, basically it can be used on the outer space. So the recent news, you will see. Nokia and other company doing the moon communication based on 4G. You may be heard about that news. So that's why we are using it. But actually we are doing that plan years ago. And you will heard about using the 700, 800 MHz and you will heard about, hey, what is this band? What is this band? The band definition is here. So you can, in Singapore you may check your operator. What is your link signal? What is your downlink signal? And you plus mode, what is this? Basically it's based on FDD, Frequency Division. So 2G and 3G, 4G network architecture. We all know, in 2G and 3G, we know Peggy switch and circuit switch. So in 2G and 3G we will know, if you want to call a voice call, you will base on the circuit switch. So it's on circuit switch. So the signal is different. But when you want to use the GPIS, you will use the Peggy call. So in 2G and 3G, base is total different. But the 4G structure will be simplified. Why? Because from the UEN we will also, this is enough, I will address it later. After that, this place is always digital and Peggy. E-norm B is involved, norm B. The capacity is high. The coverage is about 2km and even to 10km. The power is about 50 watts. So the call is 2G and 3G as you can see. Wow, so complex. So why we are doing the base version 4G? Because we want everything to be simplified. So you can see the EPC call has evolved. Peggy call has been EPC. So the EPC is this. This is EPC. So you know the EPC and later I will show you how to use SPR. So you have the basic information for this. So I have introduced this. EPC is involved with Peggy call network, SGSN and GGSN. These two words are for 2G and 3G. So EPC is an old Peggy call network from 3GPP release. You can see this is the EPC here. So the basic will be the involved Peggy system. So this is an old new network. You can see the service gateway SGW, Peggy data network PTN and mobile mobility management element and PCI. So it's the basic for the EPC. Alright, next topic. What is SPR and SPR can do? I want to introduce this. This is our logo for our QCEN. We decided this for our Yu-san QCEN. Sorry for my advertisement. SPR is a non-new concept. It's a very old traditional. Everyone may play that before. You will know what is very powerful. You can use it to do anything you want. You can create a crack or even a new idea. Or even you want to do a Lora-based or Sycfax-based protocol. If you want to do your protocol, you can design. This is SPR Proc. We all know that the core is... You have to have an FPGA-based. You have a digital front-end. You have a front IC to receive and the ADC and the DAC. So based on this, you can use the software algorithm here. Here is our core. You can use a GNU radio companion to use the basic widgets or flow to be your basic... Alright, what do you need? I just simplified because there are many kinds of STI in the world. You can buy it, but actually I use it always. I like this very much. It's an open source hardware. So you can customize with your version. If you have a hardware experience, you can do your version. Version, sorry. Make your hardware for fun, for hackers. If you want to do this, contact me. We're also doing something like IoT device, make your own protocol like Sycfax or NBLT, just like I said. So if you really have a hard work for the hacker best, you can do new product. Really, I just mean it. You can do it. Just mean the French are the French making a new product. Just mean we all know Sycfax, right? They control everything. Sycfax station. If you want to do this kind of business, you have to cooperate with them and they will sell you the Sycfax chip. This is just a transmitter. Not a center receiver. It's a transmitter. So you just can send out a signal just like that. But you have based on the Sycfax station. All right. The core is J-Radio. You can see the right side. They are always rigid. So if you do not know about the core, there's no matter. You just have to read about it. How to use the logic or the algorithm. What's the meaning for the STL? So when you have a Linux, you can deploy, you can compile it. If you have Mac, you can compile. If you have Windows, you can compile in your desktop. It's OK. So everything is rigid. Everything is closed. So you can combine your idea into your new idea. So that's the flexibility. Very good. So you can see the variable. You have a really synchronized source. You can add and put. You have input, you have output, just like this. You can use it. If you have the basic Macs, you just know that. Because the iPhone, you know, radio frequency, it is based on the basic carrier. So you can make some noise on it, make some signal on it. And it will be very interesting. It's an interesting thing. OK. Let's say hello. In these models, you can put your file. This is hello world. And I put the hello world in the file source. OK. Your file source can be anything. Test file, image file, anything you want. So put it on. And the output will be there. So you can have a hacker in one building. And the next, hang on, in the next building, if it is far away, it's no matter. But you have to decide your basic frequency. OK. This is the best for decoding the LTE. This is the call we want to use. We want to use it on our Qt set. Let's just show you the call. OK. But because we know what we are doing there. So I'll just show you part of that. All right. You do not want to know more about this. You just can use the company name. It's called Eurocom. Eurocom has just finished some 4G or T spec. They have implemented everything you want. We just know 3GPP released 8. They just implement the whole set. So you can use the OAI. The OAI is over there interface. So you just see all file of 3GPP EPC. I just told that before, a few minutes ago. So they have implemented the EPC spec and fully supported. And OAI, UE, and EMP. I will say UE is a user equipment. UE is maybe your mobile phone is a user equipment. Or UE will be my Qt set, mark in Qt set. So you just know UE. And E0V is a, we just know it's a evolved node. It's a station. It's a small-cell station. Because 4G, LTE is a small-cell, small-cell, small-cell. So we all know that ENV is here. It's an ENV. So you can do your soft ENV. So when you back home, you download this. You can compile it. But you have to buy HCI first. So finish your experiment. All right. I want to introduce what is office space. And how to involve this. It's not very easy to enter. But if you want to go inside, you will feel very funny and have fun at least. Because you can do anything you want. You can do hardware. You can do your embedded system. You can do everything you can. So I will introduce this is Earth. This is orbit plane. And we always choose our satellite to fly. And how to choose your orbit. This is our equator. The equator is the basic line. So you have to decide your degree. All right. So the orbit plane is your design, the degree. All right. Sorry. I will keep saying you said it will be launched in 2019. We have AIS and APIs. AIS is a universal ocean. We will collect the AIS. When we fly over the region, we will collect. And finally, we will put the AIS signal into our cloud. Finally, and there will be the big data in the ocean. All right. Because AIS has some information. But it's only GPS and direction. All right. Almost. Thank you. Thank you very much. No problem.
