 So we're here with the open EPC, so who are you? So I'm Dragosh Vingerzana, I'm co-founder and city of a spin-off company of a big research institute in Germany. And what are you showing here? Yeah, here we have an entire mobile core network on a simple raspberry point. So we're thinking everything that big operators are having in big data centers. And we're showing that actually we can have it on a very efficient platform and power it over USB in practice. So what is it that you have? That's like LTE broadcasting solution or what is it? Yeah, so it's actually you can establish a small mobile network on remote islands or for public safety purposes and so on. And here's the whole mobile network, here we have the base station. So here's the LTE base station. It also works with 2G, 3G and Wi-Fi base stations. And this basically connects to a phone that is inside of this Faraday box. And yeah, we close it up so we don't need to use the local mobile networks. Inside there actually we have a standard Galaxy S4 device. And yeah, we're just putting it outside of the box. What is it? You know when they have real LTE radio we're not gonna use the networks here. And this is another Raspberry Pi actually. That just shows us what happens inside the box. So we don't have to open it and what's inside stays isolated from an RF perspective. So the Raspberry Pi is an ARM 11 CPU right? It's not even a very high performance. I think it's actually an ARM 7. ARM 7, yeah. So yeah, no actually it's really really low power and everything. And how do you make it work? Efficient software. Efficient software? Yeah, efficient Linux software. You rewrite everything or you just use the same software that's used on big machines? Exactly. So we took a team of 10 researchers and we gave them a challenge. And yeah, they did what typically big network equipment providers would do with hundreds of engineers. So what is OpenEPC? It's the entire platform, the entire software platform. So it's open? Is it open source? No, unfortunately it's not open source but we do license the source code. So who are your customers? Here it is. Here it is what we have. These are the components that we have in the core network. And in this Raspberry Pi actually we implement the entire mobile network as you can see here. So that we have all the functional elements that we have in the normal network. In this demo we are using just FTE but it's capable also of 2G and 3G at one point. And has the latest sort of 5G core network features. So who are your customers? Our customers are the special purposes guys. So public safety, IoT operators that make something really different from the standard equipment providers would give you. So what do you think about ARM, the ecosystem? Oh it's great, I mean we're typically running this on a cloud platform but to be able to go down on such a very low platform and to demonstrate that even such a very very small and USB power device can provide 10 to 15 Mbps it's just awesome. So you could optimize for any of these ARM networking solutions coming out, 64 bit, stuff like that right? Well with that are you working on this? I think a bit per second and the wire speed performance, this is really just power efficiency at its best. It's just a demo right? Yeah, it's just power efficiency at its best and if you need it it's basically it goes into... Let me just turn it on a little bit so that actually it will attach to the network. So this goes into the direction of creating mobile mobile networks because we can bundle the core network with the cell and put it for example in every vehicles and so on. So for disaster relief this would be an ideal and cost efficient and energy efficient solution.
