Many observers believe that the overwhelming number of internet of things devices in use by 2024 or 2025 will use some short-range form of connection, such as Bluetooth or Wi-Fi. That does not directly correlate to the location of data processing, which might be on a connected device (smartphone) local premises device, regional data center or far-end remote data center.
But the shift to local connections for IoT does at least suggest a growing role for edge computing of various types.
By 2024, IoT device markets will represent 31 percent of total Bluetooth and 27 percent of Wi-Fi device shipments, up from 13 percent and 10 percent respectively in 2018, say researchers at ABI Research.
Smartphones will continue to be important markets of strength for both Bluetooth and Wi-Fi , but Bluetooth shipments for the IoT market will overtake the smartphone market for the first time in 2024.
Ericsson forecasts mirror such expectations, showing the greatest unit growth in the connected device market coming from short-range IoT.
Smartphones as a proportion of Wi-Fi device shipments will fall below 40 percent by 2024.
“ IoT is beginning to take an increasingly significant share of the market,” says Andrew Zignani, ABI Research principal analyst.
Key IoT opportunities for Bluetooth will be found within asset management and location services in devices such as beacons and personal trackers. These are anticipated to grow from around two percent of the Bluetooth market in 2018 to over 8.5 percent by 2024.
Analysts at IoT Analytics agree that short-range connections will dominate IoT connections by 2025.
Bluetooth-enabled wearable devices are also expected to break the 400 million device barrier by 2024, with increased traction in smartwatches, activity trackers, smart clothing, and hearables, the firm predicts.
Wi-Fi-enabled wearables are also expected to reach over 250 million units by 2024.
The smart home will be one of the quickest growing markets for both Wi-Fi and Bluetooth technologies. Wi-Fi-enabled smart home devices are expected to grow from five percent in 2018 to nearly 16 percent by 2024 and Bluetooth will rise from four percent to 13 percent by 2024, with traction in voice-control front ends, smart appliances, smart lighting, sensor devices and video cameras, ABI Research estimates.
