Walking for five minutes behind Qualcomm's main office in San Diego, you will find an unlikely laboratory. In an empty conference room, previously used to store office furniture and boxes, it has become a new wireless technology for the mobile chip giant's experimental field. You may not expect to focus on 5G. Although 5G means super-high speed for smartphones, it's just the beginning.

Inside the door, a tall 5G antenna transmits signals to the other side of the room. The net is on the side of the test area so that people do not accidentally step on the blue foam pad on the floor. Deep in the room, there are two cars equipped with modems and cameras, which can detect whether pedestrians are blocking the road and promptly remind drivers.

In a distant corner, hidden behind large wooden boxes and metal carts, Qualcomm has set up tests for automated robots in factories. The wall-mounted antenna uses the building's dedicated cellular 5G network to send 5G signals to the factory. Qualcomm showed me a demonstration in the video, a forklift driving back and forth, blocking a beam of light. However, signals from other antennas will seamlessly cover the whole connection process and will not miss the beat.

Yes, it's a mock warehouse in a real warehouse.

Patrik Lundqvist, director of technology marketing at Qualcomm, showed me around the demonstration and said, "We moved the lab to the most realistic environment possible."

Robots and cars are just a few examples of machines and devices that could benefit from the rise of 5G, which will change the way we live and work. This highly publicized technology runs 10 to 100 times faster than the current typical 4G cellular network connection, and it responds much faster than 4G and Wi-Fi. 5G provides more network capacity, allowing more devices to connect at the same time. And it's more reliable than other wireless connections.

Once the 5G network is built. Early tests showed that the coverage of 5G was uneven and inconsistent.

The initial promotion of 5G seems to be all about mobile devices. Ultra-high-speed wireless networks will allow us to download gigabytes of data in seconds and play real-time video in ultra-high definition. We'll be able to do things on mobile devices that we've never done before -- almost instantaneously. Just as 4G brings services such as Ultimate taxi and Facebook Live, 5G will also bring services that we never imagined.

But as I saw in Qualcomm's warehouse lab, 5G has the power to change more than just mobile phones. It has a huge impact on robotics, automobiles, medical equipment, retail and almost every industry you can think of. 5G can connect street lights to other devices that were not previously connected to the Internet, and ubiquitous sensors can constantly communicate with each other. Emergency responders will be able to do more at the scene of the accident, and farmers will be able to monitor their crops and livestock. Even cattle can be connected to the Internet.

Some of these functions can now be implemented in 4G. But what's really important about 5G is the critical moment when the network has to respond faster and carry more data. Robots that operate or build cars cannot be disconnected from physical cables unless the signals are very fast, stable and responsive. Although you can now connect smart watt-hour meters with old wireless technologies, you can't connect the entire grid. If a tree falls on the wire, you can't instruct it to automatically adjust the power supply. With 5G, you can do it.

"When you can move information on a large scale, new things become possible," said Gordon Smith, chief executive of Sagent, a telecom equipment distributor. "[5G] becomes a powerful promoter."

Qualcomm Chief Technology Officer said last Friday that if Qualcomm did not have to launch independent modems for Apple, it would not invest time and money in updating them every year.

James Thompson, who testified in court on behalf of Qualcomm, said it costs about $250 million a year to adjust its modem for Apple.

"Apple requires us to launch a new product every year," Thompson said. "But if you look at our other customers who use these products, such as data card business, they don't even want us to make a new design every year."

Having the fastest modem allows us all to access websites or streaming videos faster. Each generation of wireless technology has brought us a leap in the previous generation of technology. This year, 5G modems will begin to appear on mobile phones, providing download speeds that are 10 to 100 times faster than the current average mobile phone connection speed.

Apple has designed its own application processor, the brain of the iPhone, but it relies on third-party chips for network connectivity. From 2011's 4S to 2015's 6S and 6S Plus, the only supplier of these chips is Qualcomm.
