While running 5G on these lower frequencies is still possible, that’s not its ideal home. Low-band 5G will only offer incremental performance gains over 4G/LTE for various reasons.

5G in the C-band frequency range can interfere with aircraft altimeters, which help pilots see better when visibility is low. For that reason, a new rollout of the wireless technology caused ...

Eventually, carriers could use a much larger range for C-band 5G networks. Currently, lower frequencies are used by T-Mobile for mid-band networks, as well as some 4G networks.

The speed and range trade-off Before we discuss the frequency ranges used by 5G, it’s essential to understand why so many different frequencies are needed.

On the opposite end of the spectrum, high-band frequencies, especially mmWave bands, are excellent at providing screaming-fast speeds, but terrible at reaching very far or penetrating buildings.

So 5G Plus is the equivalent of 5G Ultra Wideband. T-Mobile meanwhile uses Extended Range 5G to describe low frequency 5G, and Ultra Capacity 5G (also known as 5G UC) for C-band and mmWave.

After all the talk of possible interference with aircraft, still, for AT&T and Verizon users, C-Band 5G on the ground can actually be a good thing.

The U.S. Army of the future may move away from the traditional radio frequencies toward little-used spectrum in part by using card-based radios, liquid metal antennas and laser communications. Today’s ...

Governments that assigned broadband wireless frequencies in the extended C-band thought the problem could be limited by frequency segmentation. This has proven to be ineffective in real-world tests.

The Federal Communications Commission has overseen Verizon's and AT&T's careful deployment of 5G in the midband C-band frequency range to temporarily limit coverage around airports, giving ...
