What is C-band 5G? Verizon and AT&T are flipping on the switch in the US

The next-generation of wireless technology is now even faster for 5G users in some parts of the country.

Telecom companies have rolled out 5G networks to various locations across the United States over the last few years, delivering an experience that's arguably only a notch above what 4G offers. But on Wednesday, Verizon (VZ) and AT&T (T) turned on their C-band 5G networks -- an important set of radio frequencies that will supercharge the internet as we know it.

"The impact will be that users will likely consume more data, the connection will be more robust and most likely we may see new types of applications emerging," said Dimitris Mavrakis, senior director at market research firm ABI Research. "5G is also positioned toward enterprise services, so this upgrade may push both carriers' plans to address this domain even further."
