Question: Hi, I just had a general question about small, at home, wireless routers and their interference with satellite signal. I live at Snowshoe, WV, about 25 minutes away from the satellite and observatory in Green Banks, WV. Before buying a router for myself, even though friends both north, south, east, and west of me have them, I wanted to clear up any questions I had about them first and make sure that there was no way it could interfere with satellite signal. Thank you. – Jesse
Answer: For those readers who might not know, what you are referring to is the restrictions on radio transmitters within the National Radio Quiet Zone (NRQZ). The NRAO Green Bank telescope facilities are within this NRQZ, which helps to limit the interference that the radio telescope facilities can experience when a man made transmitter is used near the observatory. I believe that home wireless routers that are located many miles away from the observatory are not a source of harmful radio frequency interference to the telescope operations. If you were to use one of these routers near the observatory, though, then the potential for them being a source of interference is much higher.
