**Bluetooth 3.0 + HS (2009):** High Speed, utilizing 802.11 (Wi-Fi) for faster transfers.
**Bluetooth 4.0 (2010):** Introduced Bluetooth Low Energy (BLE), designed for low-power applications. This is relevant to the Internet of Things (IoT) and the data streams generated, which can be analyzed for market sentiment using sentiment analysis.
**Bluetooth 4.1, 4.2 (2013, 2014):** Further improvements to BLE and security.
**Bluetooth 5 (2016):** Doubled speed, quadrupled range, and increased broadcasting message capacity.
**Bluetooth 5.1, 5.2, 5.3 (2019, 2020, 2021):** Continued improvements to features and efficiency.

How Bluetooth Works

Bluetooth operates using radio waves in the 2.4 GHz ISM band. This band is globally available, but subject to interference from other devices like Wi-Fi routers and microwave ovens.

**Frequency-Hopping Spread Spectrum (FHSS):** Bluetooth uses FHSS to minimize interference. The transmitter rapidly switches between 79 different frequencies within the 2.4 GHz band. This makes it more robust against interference and eavesdropping. The rapid switching can be likened to the constant volatility in the binary options market.
**Piconets and Scatternets:** Bluetooth devices communicate in small networks called piconets. A piconet consists of one master device and up to seven active slave devices. Multiple piconets can be interconnected to form a scatternet.
**Profiles:** Bluetooth defines various profiles that specify how devices should interact. Examples include:

   * **A2DP (Advanced Audio Distribution Profile):** For streaming stereo audio.
   * **HFP (Hands-Free Profile):** For voice calls.
   * **HSP (Headset Profile):** For basic headset functionality.
   * **OPP (Object Push Profile):** For transferring files.
   * **HID (Human Interface Device Profile):** For connecting keyboards and mice.

**Data Rates:** Data rates vary depending on the Bluetooth version. Bluetooth 5 can achieve speeds up to 2 Mbps. Higher data rates are crucial for transmitting real-time market data, impacting the effectiveness of momentum trading strategies.
**Power Classes:** Bluetooth devices are categorized into power classes, with Class 1 having the highest power (100mW), allowing for the longest range (up to 100 meters). Class 2 (2.5mW) and Class 3 (1mW) offer shorter ranges.
