The requirements of a 5G network will be real data rates of 1 to 10 Gbit/s, rather than theoretical peak rates, coupled with a 1 ms end-to-end latency, which is a key advantage for IoT developers. The wider network will have to support 1000x the bandwidth of today’s cells and 10 to 100 times more devices connected at the same time, which will again allow for many more connected devices of all kinds in the Internet of Things.
Internet of Race
With 5G, the scope and scale of IoT is going to be so impressive. Imagine a city filled with a swarm of sensors, monitoring everything from traffic to environment and air quality to critical services, and this information can be communicated back to you as you navigate the city’s streets.
Internet of Safety
Think about sensors in our forests that are able to detect fires early and communicate that data to emergency responders or think about sensors attached to buildings which would alarm before building structure is in danger which would save the many. Think heavy manufacturing robots in car factories that can react lightning-quick to safety issues.
Internet of Cars
Send an SMS on a 4G network and it will take at least 40 milliseconds. Do it on 5G and it takes one or two milliseconds. 5G’s low latency characteristic is all about safety. 5G will allow a driverless car to respond to a red light, or exchange data with a nearby vehicle to help avoid a collision. That exchange of information is critically important for autonomous cars
IoT Going Deep Underground
Sometimes a device will be so remote, or so deep underground, that traditional uplink communication won’t be an option, even at narrow, low-frequency bandwidths. It might be something as simple as a gas meter in a basement or as complex as mobile mining equipment deep underground.
5G will optimize the downlink transmissions to ensure deep coverage for these devices. For the uplink transmission, 5G can additionally support the use of non-orthogonal multiple access techniques, such as Resource Spread Multiple Access (RSMA), for target use cases such as sporadic uplink traffic from battery-powered IoT sensors. 5G devices will also support multi-hop communication, managed by the network. This will allow messages to be relayed until direct coverage is available, which allows these devices to use far lower power transmissions.
For all the convenience and efficiency that 5G could bring to the Internet of Things, it’s in healthcare that the most wondrous example of real-time communications could exist.
That low latency will have real-time applications in healthcare, such as remote operations using robotics or even doctors and surgeons could – using a 5G network – examine a patient in real-time using a telepresence unit, and even perform an operation remotely. Think of a patient in a far-flung rural village without permanent medical personnel having a life-saving procedure performed by a surgeon in a remote city. The latter would require haptic gloves attached to a surgical machine, though the swapping of real-time brain scans over 5G – and perhaps even the creation of virtual clones of patients for surgeons to operate on – make 5G healthcare enticing.
The smart city
It’s not just the cars that need 5G, but the urban infrastructure at large.
5G would allow cars, equipped with sensors to talk to other cars, avoiding accidents, even traffic lights would be so smart that would be changing real time as per traffic. Smart education everywhere, monitoring of crimes in the city etc. Thinking of the city infrastructure itself could come alive.
The development of 5G networks is accelerating, delivering significant advantages for IoT networks in the future. The 5G frequency bands with dramatically lower latency and much higher capacity and millions of devices connected to the network which would be used in ultra IOT applications with millions of sensors making IOT feasible. With ultra-low-power and long battery life, wireless nodes can be easily implemented and cost-effectively deployed.
