+## Legacy 1 Bench
+
+**Purpose** : FDD Band 7 and Band 13, LTE-M  
+**Note** : Legacy1 and Legacy2 are duplicated so that they can run in parallel, thus avoiding a CI bottleneck  
+**Note** : Faraday Cages 1 and 2 are physically the same cage

+## Legacy 2 Bench
+
+**Purpose** : TDD Band 40, TM2 2xTX 2xRX  
+**Note** : CN can run in a container, could also run on Massive
