Bluetooth 5: Differences and Advantages in Bluetooth Glasses | Hacker Noon

Bluetooth 5 is a radio technology that is used for the Internet or transmission from smartphone to smartphone or even to speakers. The best thing about the new specification is the huge improvement in speed of up to 2 Mbit / s. In addition, there is up to four times the range and there is an800% increase in the transmission capacity for broadcasts. Bluetooth 5 can already do a lot more than its predecessor versions and further developments give hope for even greater improvements. The advantages are the greater range, the faster speed, and the greater transmission capacity.

To put it in a nutshell: The best thing about the new specification is the huge improvement in speed of up to 2 Mbit / s.

In addition, there is up to four times the range.

Inside buildings up to 40m and outdoors up to 200m. In addition, there is an 800% increase in the transmission capacity for broadcasts.

Range

The previous range of the last version 4.2 was approximately 100 meters. But that was mostly only the case on paper because many devices could only cover around 10 to 50 m to save electricity. The new version manages to increase this range and still save electricity costs.

Speed

Even in power-saving mode, you can now achieve 2MBit / s instead of 1 MBit. The speed is linked to the range. That would mean that you can increase the data rate in economy mode or increase the range at 1 Mbit to up to 40 m indoors or 200 m outdoors.

Transmission capacity

The fact that the transfer is improved by eight is also due to the fact that you can now transfer data packets with a size of over 250 bytes instead of the previous 31 bytes.
