Around 1981, as you can see, we had 1G, right? It was only cell phones, nothing else.
Norbert HeuserGUEST
10 years later, where 2G, you had cell phone and you could start to text message.
Norbert HeuserGUEST
Then 10 years later, again, 3G, cell phone, text message, and online.
Norbert HeuserGUEST
Another 10 years later, 4G, Everything is above, but with a higher speed and more information.

Steve O'BrienHOST
And then you could just listen to it.
Steve O'BrienHOST
The second generation, 2G as they like to call it.
Steve O'BrienHOST

When mounted inside a moving vehicle, it broadcasts a signal that tricks every nearby smartphone into believing it's the strongest, closest available tower.

It's safe to say Joaquín Tordesilla, now the VP of Software Transformation at Keysight, knows his wireless technology.
Daniel BogdanoffHOST
He's here to break down what's hot in wireless right now: non-terrestrial networks, early 6G efforts, and the growing role of software in test and measurement.

Joaquin TorrecillaGUEST
Yeah, no.
Joaquin TorrecillaGUEST
The, the group that was, uh, acquired by Agilent, we were working in Bluetooth, but we were also working in 2G, 3G, 4G solutions.
Joaquin TorrecillaGUEST
And at that time we had an active, an active, uh, multi-standard, uh, what we call one box tester that is a network emulator, a box that, uh, simulates a whole network so that when, when you put a mobile phone in front of that box, it believes it's connected to a real network.
