@prabhakar_deosthali, that's true but we are only starting to scratch the surface of the IoT ecosystem, and most devices only transmitt a few kbytes of data.
Using IPV6 and a combination of 3G/4G/5G networks can support the connectivity. Bandwidth problems are occurring because heavy use of multimedia applications on mobile devices, something it didn't happen until a few years ago.
True! IPV6 will solve the problem of unique adddresses to the devices .
But what about the bandwidth requirements.
Assuming we allow free flow trafic between all the devices world wide over the internet of things , the bandwidth requirements of routers,swicthes and all those intermediataries will increase many thousand times . The wwwhole internet infrastructure will need an overhaul.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
