What is Bluetooth 1.1? - Explained

Bluetooth 1.1 is the updated version of Bluetooth 1.0 and 1.0B. After recognizing the bugs and the usability issues in the version 1.0 and 1.0B, the engineers issued the latest version of Bluetooth as version 1.1 Bluetooth. 


Bluetooth 1.1 operated in the same frequency layer which is 2.4GHz to 2.485GHz frequencies. To enhance the wireless frequency modulation, Bluetooth adopted the standard by IEEE 802.15.1-2002.

The major bugs which were there in the initial version 1.0 and 1.0B Bluetooth got fixed and released after successfully test cycles.

Version 1.1 Bluetooth got empowered with the capability of using non encrypted channels to communicate data which enhanced the speed of transmission and receiving the data which sent by the peer to peer.

To enhance the user experience and to upgrade the firmware version, Bluetooth 1.1 got received signal strength indicator or RSSI. RSSI helped the bluetooth's firmware to run smoother and efficient when the signal strengths are low with distance and interference.
