I’ve been thinking about this before. If the fitness tracker can use WiFi to transmit data indoors and automatically switch to Bluetooth outside, will the transmission speed be faster?
But can this vision come true?This estimate will be a little difficult.Because wifi transmission speed although fast, but relatively large power consumption.The bandwidth required for fitness tracker smart bracelets is very low.
And the power consumption of Bluetooth is over 4. It can be said to be rather low. The battery life at low speed is not an order of magnitude compared with that of WiFi. A lot of BLE beacon, a button battery can be used for 2 years.
From all aspects of power bandwidth, Bluetooth is more suitable for smart fitness trackers.
