Bluetooth 4.0 BLE-Based Smart Wearable Solution

Smart wearable solution is the intelligent design and development of daily wear, Bluetooth 4.0 BLE technology will soon become the agreed connectivity solution for wearable technology. For this reason, WorldPing Group has launched Bluetooth 4.0 BLE-based smart wearable solutions.

Wearable devices will see a high growth phase, with the economy of this market reaching $50 billion in the next 5 years. From smart watches to fitness trackers, the various wearable device markets are showing significant growth. But all the daily necessities, such as glasses, bracelets, clothes, shoes, and even hats, can use Bluetooth wireless technology to send the collected activity data to the application software of smart phones or tablets, and through the data analysis in the cloud, give back the information such as health tips to the users.
