Power Relay will allow you to power up another rooms, Resistance Comms will increase the overall number of contacts, which will make establishing connections with the resistance a lot easier, and in turn increase your influence zone and supplies given to you by the Council. To construct Resistance Comms you will need to complete the Resistance Communications research, which is why that should be your priority. Those are: Power Relay, Guerilla Tactics School and Resistance Comms. The order in which you must construct the facilities on the Avenger is mainly optional (as every player likes a different approach to the game), but there are a number of facilities that you should construct as quickly as possible.
