The launch of the blisteringly fast 5G mobile network over the next decade will not kill the wires-in-ground $84 billion National Broadband Network, according to Telstra executives.

Telstra is embracing 5G technology after launching a trial hotspot area on the Gold Coast in March and announcing plans to begin offering some 5G services by next year.

But the technology has been touted as a potential NBN-killer, even by the outgoing NBN Co chief executive Bill Morrow, because of its 20-gigabits-per-second speed.

That's 20 times faster than the current mobile standard 4G and significantly quicker than the best NBN plans offering 100Mbps.
