Introduction
The coming of 5G and the foreseen future of even faster networks are massively changing the world of wireless connectivity. Ultra-fast networks will obviously power IoT applications from smart cities through to healthcare and industry. But what exactly is it about 5G, and the technology that follows, that makes this network so transformative for IoT?
In this blog, we see how 5G and beyond enable the new era of connected devices, potentially impact different sectors, and what future holds because of continued network evolution.
What’s so special about 5G for IoT?
First of all, the differences between this generation and the previous ones should be understood to figure out the impact:
- Speed and Low Latency: 5G networks are up to 100 times faster than 4G, featuring download speeds that top 10 Gbps. But perhaps the most game-changing thing it is that its very low latency—that is, situations when data transfer between devices happens without noticeable delay—response times may go down to as low as one millisecond.
- Higher Device Capacity: As compared to 4G, the typical capacity of this network could handle a very large number of connected devices. That makes all the difference in IoT applications. This capacity, in essence, enables the deployment of millions of IoT sensors and devices over a small, concentrated area, which could be an urban city hub or an industrially developing area without causing congestion over the network.
- Network Slicing: 5G introduces the concept of network slicing, where network operators can create ‘slices’ of network resources that are dedicated to specific applications. For IoT, this opens up the opportunity to run parallel, specialized slices for applications of various different needs—for instance, high-speed versus low-power applications—without mutual interference.
These features make 5G ideal for IoT applications where speed, responsiveness, and scalability are key issues.
5G and Its Effect on Major IoT Vertical
1. Smart Cities
The whole concept of a smart city is basically to utilize IoT to make urban life more efficient and qualitatively superior. With its capabilities, cities can deploy millions of connected sensors across infrastructure, public spaces, and transportation systems.
IoT sensors on 5G can manage traffic flow, diligently adjust the traffic light controls, and reroute cars in real-time to avoid congestion.
- Public Safety: High-speed, low-latency these networks would enable the rapid sharing of data between video surveillance cameras, sensors, and public safety agencies to support improved emergency response times and enhanced public safety.
- Energy Management: Smart grids use real-time data on electricity demand to improve the management of the distribution of economical and ecological energies in the city, including renewable sources.
It allows for dense sensor networks, which will enable cities to scale their IoT solutions much larger and open the way toward smarter, safer, and more sustainable urban areas.
2. Healthcare
It will also greatly benefit healthcare as it would facilitate real-time data transfer and analysis, which is so crucial in patient care.
- Remote Surgery: With the ultra-low latency of 5G, the dream of remote surgeries over distance is becoming a reality where a surgeon, located somewhere else, conducts an operation on a patient with robotic arms and high-resolution video.
- Telemedicine: 5G will enhance telemedicine capabilities, like enabling high-quality video consultations; these are going to revolutionize access in both rural and remote areas where connectivity has been poor.
- Wearable Health Monitoring: Wearable devices, such as heart rate monitors and glucose sensors, can continuously stream patient data to healthcare providers for real-time monitoring and proactive care.
5G networks guarantee reliability and speed at which health data will be delivered and acted upon in real-time; thus, opening an entire world of innovations in patient monitoring, diagnostics, and treatment.
3. Industrial IoT (IoT)
IoT has been driving efficiency and productivity in manufacturing and industry. In fact, with it, full capabilities of IIoT are realized.
- Smart Factories: Factories can monitor equipment in real-time with 5G-enabled IoT sensors and devices by fault detecting and maintenance needs forecasting well before any failure of equipment occurs. This reduces downtime and improves operational efficiency.
- Automated Robotics: 5G enables autonomous robots and vehicles to be used within an industrial context, with real-time control and coordination again being essential to safety and productivity.
- Supply Chain Optimization: IoT devices run on 5G enable location tracking of goods for improved logistics and decongest the supply chain.
Ultra-reliable and low-latency communication in 5G means IIoT devices will be able to operate both safely and effectively, even in a complex environment where split decisions are part of the process.
4. Agriculture
IoT-driven precision agriculture will improve yields per unit area with reduced use of resources in agriculture. All these are helping to make the vision a reality, and foremost among them is 5G.
- Real-Time Crop Monitoring: Sensors on farms can monitor, detect, and track soil moisture, nutrient levels, along with many other variables to continuously feed a computer analyzing the data to attain optimal crop health and productive yield.
- Drones and Autonomous Vehicles: It can enable such drones to provide high-resolution images, conduct other day-long pesticide applications and irrigation. It will allow autonomous tractors and harvesters to act more efficiently.
- Livestock Management: IoT devices can track the health and location of livestock and send an alert to the concerned farmers about any health issues or concerns. With this, it will be analyzed there and then itself.
Due to their speed and range, these networks will enable farmers to make precise, timely adjustments based on data-driven insights, boosting productivity and sustainability.
5. Transportation and Autonomous Vehicles
Perhaps among the most transformative areas in which the use of 5G-enabled IoT is seen is transportation, especially in the case of autonomous vehicles.
- Connected Vehicles: It lets the vehicles talk to other vehicles and infrastructures for V2x communication, hence enhancing safety and reducing congestion. The potential of the vehicles shall be able to make more knowledgeable decisions while driving by transferring data in real time.
- Autonomous Driving: This is requiring a large input of data to make split-second decisions independently. 5G offers the bandwidth and minimum latency that will accommodate the right communication between the vehicles and the systems governing them.
- Public Transport Optimization: Sensors linked with 5G may optimize routes, monitor the performance of buses and trains, and provide real updates to commuters.
5G can facilitate the collection, analysis, and taking of actions based on data from many vehicles and sensors to create a safer and more efficient transportation ecosystem.
Looking Ahead: Beyond 5G
But if 5G is transformative, work is already underway on the next generation of wireless technology called 6G, promising even greater speeds and lower latency but also more advanced capabilities.
What Could 6G Bring to IoT?
- Even Lower Latency: 6G might pride itself on latencies as low as a couple of microseconds that could enable real-time communication, which is critical in life-critical applications like telesurgery and advanced robotics.
- Higher Data Speeds: 6G should reach 1 terabit per second to enable such applications that we cannot even conceptualize—real-time 3D holography and ultra-high-resolution VR.
Challenges and Considerations
Despite the great expectations of 5G and the future 6G, several challenges still persist:
- Security and Privacy: Several million devices will be interconnected, which raises major concerns regarding data security. The networks will have to be strongly guarded against infiltrations from cyber threats.
- Infrastructure Costs: Building out these cell networks, including 5G in the future, is expensive and necessary to achieve large infrastructure investment, particularly in rural and underserved areas.
- Energy Consumption: The energy consumption involved in managing billions of IoT devices and their complete infrastructure triggers concerns regarding sustainability.
