Editing Co-channel interference (section)

== Bleeding of adjacent bands ==
{{Undue section|date=May 2022}}
Even with frequency planning, bleeding of signals from adjacent [[Radio spectrum|bands]] can lead to [[Electromagnetic interference|interference]]. This can impair passive [[remote sensing]] used for [[environmental monitoring]], such as by [[weather satellite]]s. The advent of [[5G]] may significantly increase deleterious effects on satellites which would impair [[numerical weather prediction]] performance, resulting in substantially adverse economic and public safety impacts.<ref name="Misra">{{cite conference  |first = Sidharth  |last = Misra  |title = The Wizard Behind the Curtain?—The Important, Diverse, and Often Hidden Role of Spectrum Allocation for Current and Future Environmental Satellites and Water, Weather, and Climate  |book-title = 15th Annual Symposium on New Generation Operational Environmental Satellite Systems  |publisher = American Meteorological Society  |date = January 10, 2019 |location = Phoenix, AZ  |url = https://ams.confex.com/ams/2019Annual/meetingapp.cgi/Paper/357736  }}</ref><ref name="Lubar">{{cite conference  |first = David G.  |last = Lubar  |title =  A Myriad of Proposed Radio Spectrum Changes—-Collectively Can They Impact Operational Meteorology?  |book-title = 15th Annual Symposium on New Generation Operational Environmental Satellite Systems  |publisher = American Meteorological Society  |date = January 9, 2019 |location = Phoenix, AZ  |url = https://ams.confex.com/ams/2019Annual/meetingapp.cgi/Paper/352154  }}</ref> Due to such concerns, US Secretary of Commerce [[Wilbur Ross]] and NASA Administrator [[Jim Bridenstine]] in February 2019 urged the FCC to cancel proposed spectrum bidding, which this was rejected.<ref name="Samenow">{{cite news  |last = Samenow  |first = Jason  |title = Critical weather data threatened by FCC 'spectrum' proposal, Commerce Dept. and NASA say  |newspaper = The Washington Post  |date = March 8, 2019 |url = https://www.washingtonpost.com/weather/2019/03/08/critical-weather-data-threatened-by-fcc-spectrum-proposal-say-department-commerce-nasa/  |access-date = May 5, 2019 }}</ref><ref name="Witze">{{cite news  |last = Witze  |first = Alexandra  |title = Global 5G wireless networks threaten weather forecasts: Next-generation mobile technology could interfere with crucial satellite-based Earth observations  |newspaper = Nature News  |date = April 26, 2019 |url = https://www.nature.com/articles/d41586-019-01305-4 }}</ref><ref name="Brackett">{{cite news  |last = Brackett  |first = Ron  |title = 5G Wireless Networks Could Interfere with Weather Forecasts, Meteorologists Warn  |newspaper = The Weather Channel  |date = May 1, 2019 |url = https://weather.com/news/news/2019-04-30-5g-networks-interfere-with-weather-forecasts  }}</ref> Unlicensed operations or poorly regulated bands also can lead to interference.
