Smart cities, mobility at work, driverless cars, telemedicine and virtual reality. Challenges and opportunities that this technology brings.
Mature 5G networks will operate at higher frequencies and distances shorter than 4G, using a dense infrastructure of ‘towers’ the size of shoe boxes located every hundred feet only. That allows them to support billions of devices, almost without latency, at speeds up to 20 times faster than 4G. The 5G antennas also consume less power, which makes the protocol better for connecting small devices on the Internet of Things that work with batteries .
1. INTELLIGENT CITIES
According to the National League of Cities, two – thirds of US municipalities have invested in technology for smart cities. For example, San Diego installed intelligent lighting systems that automatically dim when no one is nearby, saving almost $ 2 million a year in electricity costs.
Pittsburgh is replacing 36,000 street lamps with LED technology lights that contain sensors to monitor air quality. South Bend, Indiana, installed sensors inside the sewer mouth caps that redirect water flow when levels rise too high.For its part, after installing shooting detection microphones in neighborhoods with high crime rates, San Francisco reported a 35 percent decrease in the incidents where the shooting occurred .
The upgrade to 5G will allow cities to handle more data from millions of IoT devices and install low-energy sensors that can last for years without replacement. This will expand your ability to intelligently manage vehicle circulation, air quality, energy use, public safety and more . A 2017 Accenture Strategy report predicts that the use of 5G networks to manage traffic and energy could save cities $ 160 billion.
2. THE WORLD OF WORK
Perhaps the broadest impact of 5G is on industrial and commercial IoT devices. Location beacons already transform the way goods move from inventory to shipping and delivery. ABI Research predicts that more than 500 million objects will be tracked by 2023. Precision agriculture uses sensors in the ground and cameras from the air to identify diseases in crops, determine when to water and reduce the use of pesticides . Smart factories install connected robots to automate dangerous and / or repetitive jobs.
All these changes will increase exponentially once ultrafast wireless networks are installed, with capacity for approximately 125,000 million IoT devices by 2030.
“The IoT or internet of things will be an important driver of what will be known as ‘the fourth industrial revolution’,” says Greg Bollella, vice president of VMware in the CTO office .
3. CAR WITHOUT DRIVER
According to the National Highway Traffic Safety Administration, nearly 95 percent of traffic accidents are caused by human error. Taking people off the wheel could save up to 1.25 million lives each year .
But for driverless cars to be completely autonomous, they should contact the cars around them to avoid accidents and minimize congestion. They should talk to the sensors integrated in the traffic lights, traffic signs and pavement to navigate more safely. And they will need to get answers instantly, which is where 5G networks of low latency are involved.
“Only fast networks, like 5G, can accept latencies of milliseconds,” says Kevin Curran, a professor at the University of Ulster in Northern Ireland, and group leader for the Environmental Intelligence Research Group. “It is not long before driverless vehicles share our roads and one day they will dominate them, but first we must invest in infrastructure.”
Once the infrastructure for driverless traffic is installed, the streets may become less congested and the air less polluted. With fully autonomous vehicles, fewer people will have their own cars and sharing the trip could become more common. The Boston Consulting Group predicts that this will reduce by 60 percent the amount of vehicles on city streets and emissions from exhaust pipes by 80 percent.
Visits to the doctor’s office may become as rare as home visits, thanks to the virtual tours that low – latency wireless networks and HD quality will make possible.Portable or implanted medical devices will capture their vital signs and transmit them to health care providers, allowing them to detect early warning signs of heart attacks, strokes or other life-threatening events .
High-speed wireless networks will also allow telesurgery, in which specialists located in a hospital will control the equipment in another facility located hundreds of kilometers away . That day may be closer than you think. In January, a surgeon in China who was 30 miles away successfully extracted a part of a pig’s liver using a 5G connection.
5. VIRTUAL SPACES
Thanks to the high bandwidth and low latency of 5G, augmented and virtual reality could finally become a practical reality. Virtual reality telepresence applications will allow colleagues in distant cities to work “side by side,” or sports fans to experience the roar of the crowd in the Super Bowl from the comfort of their sofas. Practically, we can tour the commercial areas of Tokyo during lunch breaks and receive the products in our homes .
All these changes will not happen overnight. Although the main operators are already busy installing limited versions of 5G in cities around the world, devices capable of accessing 5G networks are now starting to appear, and there are still several years left for ultra-high speed implementations.
It took 10G for 10 years to become the predominant cellular technology, and 5G could take even longer . But once fully established, we will wonder how we could live without it.
