Open source 5G core network
For those interested, this project seems to be a rewrite of <a href="https:&#x2F;&#x2F;nextepc.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;nextepc.org&#x2F;</a> into Go. Alternative projects include <a href="https:&#x2F;&#x2F;github.com&#x2F;facebookincubator&#x2F;magma" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;facebookincubator&#x2F;magma</a> and <a href="https:&#x2F;&#x2F;github.com&#x2F;openairinterface" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;openairinterface</a>.<p>You can start your own telenetwork with these projects (but of course doing such would be highly illegal without a spectrum license), but first, you need a gNB or eNodeB which is lingo for a base station. It is possible to buy an SDR and use software like <a href="https:&#x2F;&#x2F;github.com&#x2F;srsLTE&#x2F;srsLTE" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;srsLTE&#x2F;srsLTE</a> to make the SDR receive and broadcast LTE&#x2F;5G connections. After this, you need to have blank SIM cards to code. For example, this post instructs how to do so: <a href="https:&#x2F;&#x2F;cyberloginit.com&#x2F;2018&#x2F;05&#x2F;03&#x2F;build-a-lte-network-with-srslte-and-program-your-own-usim-card.html" rel="nofollow">https:&#x2F;&#x2F;cyberloginit.com&#x2F;2018&#x2F;05&#x2F;03&#x2F;build-a-lte-network-with...</a>. You might also consider writing eSIMs <a href="https:&#x2F;&#x2F;github.com&#x2F;bagyenda&#x2F;njiwa" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bagyenda&#x2F;njiwa</a>.<p>After this, you should be able to use a commercial phone to connect to the network.<p>In general, these networks function quite well even on commodity hardware. Some tests I worked on produced end-to-end latency of around 20ms on LTE, and throughput of around 7MB&#x2F;s. This was using NextEPC on a 400 euro computer with a 50 euro router and a Nokia base station. Further, it was possible to make the system to work in a Heroku like manner by exposing PaaS endpoints and running Kubernetes in the access network: <a href="https:&#x2F;&#x2F;www.semanticscholar.org&#x2F;paper&#x2F;Open-source-RANs-in-Practice:-an-Over-The-Air-for-Haavisto-Arif&#x2F;38aa0fcd59646de9cf54fdae812349def01fb02a" rel="nofollow">https:&#x2F;&#x2F;www.semanticscholar.org&#x2F;paper&#x2F;Open-source-RANs-in-Pr...</a><p>I think it&#x27;s quite likely that sooner or later we will have 5G networks with intra-services running as edge-services, providing us low-latency. It&#x27;s worth noting that with the latest LTE versions 5G and LTE access latency is virtually the same. The real latency-optimization would be, at least to my perspective, to allow software to be deployed _into_ these cellular networks to minimize network hops.
