作為全球應(yīng)用最為廣泛短距離通信技術(shù)之一的藍牙，藍牙技術(shù)聯(lián)盟（SIG）發(fā)布了藍牙5.0，藍牙完美的兼容在現(xiàn)有藍牙的基礎(chǔ)上，重點提升了藍牙低功耗技術(shù)性能，與藍牙4.2相比，低功耗傳輸速率提升2倍，傳輸距離提升4倍，傳輸容量增加至8倍，同時改善了藍牙在全球環(huán)境中與其他通信技術(shù)兼容。
藍牙5.0新增功能如下：
1. LE 2M PHY: 指在測試模式時使用2Msym/s符號速率傳輸有效載荷為PRBS9的LE測試包的測試Case;
2. Stable Modulation Index: 指在接收機性能測試時，設(shè)備的發(fā)射機需要設(shè)置在穩(wěn)定調(diào)制特性狀態(tài)下。
3. LE Coded PHY: 在射頻測試中分為S=2和S=8兩種情況，在測試中使用規(guī)定的數(shù)據(jù)包。
藍牙5.0在低功耗技術(shù)性能上的提升伴隨著認證時在低功耗部分測試項的增加，新增了37個測試用例，新增測試用例均針對藍牙5的新特性，具體新增測試用例如下：
