Some might argue that 5G was the first mobile platform intentionally designed to support internet of things services in addition to mobile phone services.
That noted, IoT mobile service revenues arguably represent less than four percent of total mobile service provider revenues using any mobile platform (2G, 3G, 4G and 5G combined). As important as service providers hope IoT will be, the bulk of revenues will continue to come from the staple "voice and internet access" services used by consumers and their smartphones.
On the other hand, some estimates suggest IoT will be a significant portion of the enterprise customer revenue stream, eventually.
IoT percentage of connections is higher, but revenue per connection is an order of magnitude lower than traditional phone connections, generally speaking.
At least one reason connections might not be as high as some might have forecast is that there are other ways to connect IoT devices, including unlicensed wireless such as Wi-Fi or Bluetooth and other methods.
That experience is worth keeping in mind as we start to hear about 6G platforms and their ability to support other types of enterprise or consumer applications, such as virtual reality, autonomous vehicles and so forth.
One always hears about such “futuristic” new use cases whenever a next-generation mobile platform is proposed. Rarely do the proposed innovations reach revenue scale, compared to supporting mobile devices such as smartphones.
