5G is more than its fast speeds, according to AT&T.

Todd Zeiler, AT&T's assistant vice president of network services, shared six pillars of 5G. Devices, cell site hardware, access software, transport, a next-generation core and content comprise those pillars. Zeiler was speaking to partners at TBI’s Big Event on Monday.

Zeiler clarified that fiber will still play an important role in the 5G world.

"There's a misnomer out there that 5G's going to get rid of the need for more fiber," he said. "Quite the opposite. We have to take fiber further and further to the edges of the network."

AT&T's low-band 5G network hit nationwide status this summer, reaching more than 200 million people. Low-band AT&T 5G speeds pale in contrast its growing millimeter-wave (mmWave) network – which exists in 35 U.S. cities – but provides better coverage.

"Embrace this next generation – the roaring 20's with me – as we go tell a story about six brand new pillars of architecture," Zeiler said.
