Bluetooth

BLUETOOTH

An open standard for wireless connection, capable of interconnecting two or more electronic devices.  Bluetooth technology is defined by standard IEEE 802.15.1.

  • Bluetooth 1.2
    Uses adaptive frequency-hopping spread spectrum (AFH) which resists radio interference and prevents the use of crowded frequencies.
    Bit rate of up to 1 Mbit/s
  • Bluetooth 2.0+
    Uses Secure Simple Pairing (SSP) and better information searching to correctly identify devices.
    Bit rate of up to 3 Mbit/s
  • Bluetooth 3.0 + HS
    Uses high-speed transmission via a collocated 802.11 link, known as Wi-Fi.
    Bit rate of up to 24 Mbit/s
  • Bluetooth 4.0
    New specifications = low energy demands for devices not using high bit rates.
    Bit rate of up to 24 Mbit/s
  • Bluetooth 5.0
    Capable of transmission across longer distances and up to 4x faster than Bluetooth 4.0; in addition, now also uses different speed ranges. Loses backwards compatibility with versions older than 4.0.
    Bit rate of up to 255 Mbit/s
