This article talks about 4G bring-up from scratch using the OAI code base. The idea is to collate the data available and provide a sequence of instructions that would help bring up a 4G eNB and a 4G UE in a single linux machine, using namespaces.After the setup is up, i.e, when the UE is able to connect to the eNB, the interface is tested by browsing. The results are recorded. Images are added, describing the LTE architecture, for better understanding.
