(Telecompaper) Connected wearable shipments will reach 168.2 million units in 2019 from 19 million this year and 5.9 million in 2013, according to a report from Berg Insight. The shipment of wearables, including smartwatches, smart glasses, fitness & activity trackers, people monitoring & safety devices and medical devices as well as other wearable devices, will record a compound annual growth rate of 54.7 percent. Bluetooth will remain the primary connectivity option in the coming years, but a total of 16.6 million of the wearables shipments in 2019 will likely incorporate embedded cellular connectivity, mainly in the smartwatch and people monitoring & safety categories. The shipment of fitness & activity trackers reached 13.0 million units this year. The category is expected to rise to 42.0 million in 2019, boosted by decreasing prices and new form factors. Smartwatches, currently the second most popular category, will overtake fitness & activity trackers within the next five years, driven by improved devices available in different price segments. The shipments of smart glasses is still very modest, but will likely rise, pushed by specific markets such as enterprise and medical as well as in niche segments of the consumer market.
