+# RAN resources
+
+This folder contains resources related to running RAN network on top of the frinx containerlab topology
+
+
+## SRSRAN
+
+This is currently using the SRSRAN open-source implementation of a RAN network (software only)
+
+https://docs.srsran.com/projects/4g/en/latest/index.html
+
+
+### BTS
+
+A base station can be built from the provided Dockerfile.
+The dockerfile builds the BTS software that can be run without a real hardware radios. It uses a zero MQ internally.
+It also runs LLDP.
+
+Resources:
+https://docs.srsran.com/projects/4g/en/next/app_notes/source/zeromq/source/index.html
+
+#### How to
+
+1. build the container `docker build -t bts .` (takes a long time)
+2. Add to containerlab topology:
+```
+  nodes:
+    bts1:
+      image: bts
+      kind: linux
+      mgmt-ipv4: 172.20.20.201
+
+...
+
+  - endpoints: ["srsenb:eth1", "R1_PE1:eth4"]
+
+```
+
+
+
+
+
+// TODO add the backend/core services from SRSRAN behind our datacenter PE
+// TODO add a client "device" from the SRSRAN connected to the BTS
