How has Bluetooth technology advanced?

Question

Can you send a text message from miles away, go online or call someone with Bluetooth on a smartphone? I barely never use this module. I remember 10 years plus ago sending pictures to a device wirelessly using bluetooth.

Answer 1

The original idea of Bluetooth (BT) was to connect things like mouse and keyboard to your computer (get rid of wires). The idea was to have a 1 meter (3 ft) range. Of course the range has grown with each new release has helped expand that range (along with adding equipment and functionality)

More security. Faster throughput.

Not exactly. BlueTooth is a wireless "personal area network". It was not designed to traverse long distances. By design BlueTooth is limited to about a thirty foot radius between the "host" and peripheral devices.

I can text someone using my BlueTooth wireless headphones connected to my BlueTooth enabled smartphone... "Siri, message _____", and I can also say, "Hey Google, go to yahoo.com" and my appropriately equipped/connected android device will go there...so your example is a bit flawed...
