NOAA Claims New 24 GHz Band Will Interfere With Weather Satellites

May 23, 2019, 3:45 PM by Rich Brome

NOAA, NASA, and the Navy have raised concerns with Congress that the new 24 GHz radio frequency band for 5G may interfere with critical water vapor sensors on US weather satellites. The 24 GHz band is one several new mmWave bands the FCC is making available for mmWave 5G service. Verizon and AT&T are deploying 5G this year in the 28 and 39 GHz mmWave bands. The FCC's auction of the 24 GHz band is expected to conclude on May 28th. The weather sensors in question operate at 23.8 GHz. The new 24 GHz band being auctioned spans 24.25 — 25.25 GHz. Even though the frequencies do not overlap, it is possible for adjacent radio signals to interfere due to "out-of-band emissions". NOAA claims the interference could reduce the accuracy of weather forecasts by up to 30%. The FCC and CTIA (the industry group that represents American cellular companies) both claim that such interference isn't possible.

Qualcomm will make a big push to bring high-speed mmWave 5G to more affordable phones in 2022, according to comments made by CEO Cristiano Amon during a Q&A session at the company's Snapdragon Summit event in Hawaii today. For a phone to support mmWave 5G, multiple specialty antenna modules need to be added, which can raise a phone's price by $50 – 100.

T-Mobile Maps its Expanded High-Speed 5G Coverage

Jul 29, 2021
As T-Mobile continues to expand its 5G network, PCMag reports that the company has updated its coverage maps to differentiate between its faster "Ultra Capacity" 5G and its slower but more widely-available "Extended Range" 5G. T-Mobile's 5G Ultra Capacity network uses a mid-band frequency (2.5 GHz, AKA band 41, which was inherited from Sprint) that offers faster data speeds than most sub-6 GHz 5G, and much better coverage than mmWave 5G.
