Debabrata Das, professor at IIIT-Bangalore, said cars, homes, agriculture will all become smart through connectivity, and there will soon be a time when each human being will have an average of about 100 IoT devices. That would mean 700 billion IoT devices communicating with each other. “That will put pressure on the network and bandwidth. And that’s where 5G becomes crucial,” Das said.
Compared to 4G, 5G significantly expands mobile broadband, it is enormously more reliable and has extremely low latency, and will enable massive machine-type communication. Mohan Rao Goli, corporate VP & head of tech strategy at Samsung R&D India, said in LTE (advanced 4G), we are seeing data transfers of megabits per second, in 5G, it is gigabits per second. “Latencies are further reduced from ten milliseconds to one millisecond,” he said. Navin Kumar, associate professor at Amrita School of Engineering, Bengaluru, noted that in late 2019, US electric scooter Lime declared it had done 100 million rides of its IoT-based scooters — a 16-fold increase in 14 months. He said US industrial IoT firm Samsara, which started in 2015, already has 1,600 employees and a revenue of $300 million. That shows, he said, how much the IoT space is growing.
