What is the difference between Bluetooth 5 and Bluetooth 4
What is Bluetooth 5?
Everyone is familiar with Bluetooth. At present, almost all mobile phones support Bluetooth, and many other devices such as notebooks or cars support Bluetooth. It is a wireless transmission technology, mainly used to transmit data, and is often used for wireless transmission of files and wireless transmission. Sound quality (such as Bluetooth headset).
In June of this year, the Bluetooth Technology Alliance officially announced the Bluetooth 5 (5) Bluetooth standard. After several months of revision, the standard is now officially finalized and released. Simply put, Bluetooth 5 is the fifth-generation Bluetooth technology, which is the next-generation version of the previous Bluetooth 4.
Advantages of Bluetooth 5
Compared with its previous version, Bluetooth 5 can bring twice the data transmission speed, and it can increase the data transmission capacity by 800%. In other words, with Bluetooth 5 you can transmit and receive more data at a faster speed.
Compared with Bluetooth v4.2, the range of the new standard is more than 4 times that of the former, which is especially valuable for portable speakers. Now you can take your phone to go farther away without worrying about the concert being cut off.

The bandwidth (transmission speed) of Bluetooth 5 is increased from 1Mbps to 2Mbps, and the transmission distance is increased to 4 times stronger, that is, the theoretical effective working distance is 300 meters, and the low power consumption mode is also possible.
At the same time, Bluetooth 5 can broadcast data packets of 255 Byte instead of 31 Byte, thereby reducing the transmission efficiency loss caused by interference in the 2.4GHz frequency band. In addition, Bluetooth 5 has also been enhanced for indoor and outdoor positioning, that is, it can transmit much more information to other compatible devices without the need to establish an actual connection.
To put it simply, Bluetooth 5 has greatly improved the speed and transmission distance compared to Bluetooth 4, which solves the embarrassment of the short transmission distance and slow speed of Bluetooth in the past, and prepares for the future Internet of Things, location services, and mobile phone related services.
