2/25/2023 0 Comments Wifi vs bluetooth speed![]() Using this formula, we will calculate data throughput from 4.0 to 5 when a connection is established. So, the formula for Bluetooth low energy data throughput for a connection would be: As for detail about “T_IFS”, please refer to Vol 6, Part B, Section 4.1 no matter in Bluetooth 5 core spec or Bluetooth v4.0, v4.1 and v4.2. “T_IFS” should be 150 µs no matter if you are using Bluetooth 5 or Bluetooth 4.0. “T_IFS” is the inter frame space it defines the time interval between two consecutive packets.“R” slot is the receive packet from peer device when the device transmits one packet to a peer device, the peer device would send back a packet which has a minimum packet length to indicate previous transmission is successful.“T” slot is the transmission packet it includes the frame header, payload and integrity check field, and the useful data would be located in the payload to transmit.For Bluetooth LE connection, one complete transmission period from one device to its peer device is like this: ![]() Right after Bluetooth 5 released, a developer asked me: with Bluetooth 5 higher bandwidth feature, how fast can it be? Today, we will have an inside look on Bluetooth low energy data throughput in theory when a connection is established, not only for Bluetooth 5, but also previous versions of Bluetooth low energy as well.Īs we know, for wireless connectivity, there is some transmission cost for link maintenance and packet redundancy to keep the Bluetooth connection robust and efficient. Developer can visit the Bluetooth SIG website and download the latest Bluetooth core spec here. Bluetooth ® 5 is here and it’s a major step up from the current standard for wireless connectivity, Bluetooth v4.2, with its 4-times longer range, 2-times higher speed, plus 8-times larger advertisement packet length for the data. ![]()
