藍牙是由藍牙技術聯(lián)盟 (SIG) 管理的無線技術標準結構。藍牙專為短距離數(shù)據(jù)傳輸和交換而設計意見征詢，其使用 2.4 GHz 的無許可 ISM 頻段逐漸完善。藍牙功能豐富，包括點對點音頻流傳輸以及用于照明或家庭自動化的大規(guī)模多對多網(wǎng)狀網(wǎng)絡自動化。Silicon Labs 提供靈活提升、高度集成的藍牙產(chǎn)品，可滿足范圍廣泛的應用最苛刻的要求不折不扣。Silicon Labs 設計的產(chǎn)品具有很長的使用壽命支撐能力，并配備最優(yōu)的射頻靈敏度和功耗。此外高效利用，Silicon Labs 還提供簡單易用但強大的軟件解決方案特征更加明顯，可簡化應用開發(fā)和整合過程。
