6月17日消息，藍牙技術聯盟在倫敦正式發布了最新的藍牙5.0技術標準。全新的藍牙5.0標準將于今年年底或2017年年初正式推出，同時也會更新支持該標準的設備。官方表示，全新藍牙5.0標準在性能上將遠超目前的版本，也就是藍牙4.2LE版本，包括在有效傳輸距離上將是4.2LE版本的4倍，也就是說，理論上，藍牙發射和接收設備之間的有效工作距離可達300米。而傳輸速度將是4.2LE版本的2倍，速度上限為24Mbps。

　　同時，藍牙5.0允許無需配對接受信標的數據，比如廣告、Beacon、位置信息等，這一傳輸率提高了8倍。

　　另外，藍牙5.0還支持室內定位導航功能，可以作為室內導航信標或類似定位設備使用，結合wifi可以實現精度小于1米的室內定位。這樣，你就可以在那些非常大的商場中通過支持藍牙5.0的設備找到路線。不過，在本次的發布中，藍牙技術聯盟并未提到這一項特性。另外，藍牙5.0針對物聯網進行了很多底層優化，力求以更低的功耗和更高的性能為智能家居服務。

　　藍牙技術聯盟執行總監Mark Powell 表示：“Bluetooth 5將使物聯網連接變得更加簡單無縫，顛覆人們的物聯網體驗。傳輸距離的提升將支持更多家居環境之外的物聯網設備連接，速度的提升也將支持設備之間更迅速的信息傳輸與軟件升級。此外，有了更強的廣播信息傳輸能力，Bluetooth 5將會促進Beacon、位置感知，以及其他“無連接式”服務的發展，從而提供簡易而無縫的物聯網使用體驗。”

　　Bluetooth 5預計于2016年末至2017年初發布，其在低功耗連接的距離與速度將各自提升4倍和2倍，而無連接式的廣播數據傳輸量將提升八倍。除此之外，它還能保持業界領先的功耗表現。 伴隨著數據傳輸量的大幅提升，而可被傳輸的數據將更加豐富且更智能化，將重新定義藍牙設備傳輸信息的方式，從“設備配APP”模式轉變成一種“無連接式”的物聯網模式，減少下載應用程序或應用程序與設備連接的需求。

　　調研機構ABI Research首席分析師Patric Connolly介紹，至2020年，基于藍牙的Beacon出貨量預計將超過3.71億。憑借廣播數據傳輸量八倍的提升，Bluetooth 5將進一步推進Beacon和定位服務在智能家居、商業和工業市場中的應用和部署。在極度仰賴場景感知能力如導航和跟蹤定位等情境中，Bluetooth 5無需設置連接或應用，就能向人們發送當下非常有用的定制化信息。例如，機場無障礙導航體驗、庫房庫存資產追蹤、應急響應，乃至能夠輔助視覺障礙人群出行的智慧城市基礎設施等。

　　Powell表示：“目前全球已有多達82億個藍牙產品正在被使用中，而Bluetooth 5的性能提升與未來藍牙的發展規劃讓我們有理由相信，到2020年，超過三分之一的物聯網設備都將采用藍牙技術。藍牙的驅動力和的創新能力將確保它是所有開發者在創建物聯網解決方案時的最佳選擇。”

　　第30，000家會員公司的加入，證明藍牙技術聯盟受到越來越多公司的信任，支持企業在開發物聯網產品服務時為消費者帶來最佳體驗，將產品和服務快速推向市場，并取得成功。藍牙技術聯盟成員數量規模自2015年底至今增長超過11%，第30， 000名會員Blossom Group的加入使這個數字再創歷史新高。這家研發次聲波和低頻降噪產品的新創公司的加入，進一步彰顯了各種規模、類型及垂直行業加入藍牙技術聯盟的積極態勢。藍牙技術聯盟正是通過與這些機構攜手，不斷推進技術發展，讓世界變得更加智能、安全、美好、愉快。

　　Blossom Group 首席執行官兼聯合創始人Luke Sanger表示：“選用藍牙無線技術，并加入藍牙技術聯盟是確保我們產品成功的必然之選。藍牙不但擁有無處不在、值得信賴的無線通信平臺，并且一直以來緊跟市場趨勢，與開發者和會員公司一同攜手開發具有獨創性的產品和應用。我們相信藍牙會繼續保持與其聯盟成員的緊密合作，不斷實現從功耗到物聯網連接的各種技術創新，突破進取，永遠先人一步。”

　　Bluetooth? 5 quadruples range， doubles speed， increases data broadcasting capacity by 800%

　　New version of Bluetooth technology delivers “connectionless” IoT， advancing beacon and location-based capabilities in home， enterprise and industrial

　　Kirkland， Washington – June 16， 2016 – The Bluetooth Special Interest Group （SIG） announced that its next release， coming late 2016 to early 2017， will be called Bluetooth 5 and will include significantly increased range， speed， and broadcast messaging capacity. Extending range will deliver robust， reliable Internet of Things （IoT） connections that make full-home and building and outdoor use cases a reality. Higher speeds will send data faster and optimize responsiveness. Increasing broadcast capacity will propel the next generation of “connectionless” services like beacons and location-relevant information and navigation. These Bluetooth advancements open up more possibilities and enable SIG companies – now at an all-time high of 30，000 member companies – to build an accessible， interoperable IoT.

　　“Bluetooth 5 will transform the way people experience the IoT by making it something that happens simply and seamlessly around them，” said Mark Powell， executive director of the Bluetooth SIG. “Increasing operation range will enable connections to IoT devices that extend far beyond the walls of a typical home， while increasing speed supports faster data transfers and software updates for devices. And now with the ability to broadcast a much richer set of information， Bluetooth 5 will make beacons， location awareness， and other connectionless services an even more relevant part of an effortless and seamless IoT experience”

　　Bluetooth 5， projected for release in late 2016 to early 2017， will quadruple range and double speed of low energy connections while increasing the capacity of connectionless data broadcasts by 800 percent. It achieves all this alongside its industry-leading power performance. With the major boost in broadcast messaging capacity， the data being transferred will be richer， more intelligent. This will redefine the way Bluetooth devices transmit information， moving away from the app-paired-to-device model to a connectionless IoT where there is less need to download an app or connect the app to a device.

　　More than 371 million Bluetooth enabled beacons are projected to ship by 2020， according to Patrick Connolly， Principal Analyst at ABI Research. With eight times the broadcast messaging capacity， Bluetooth 5 will further propel the adoption and deployment of beacons and location-based services in the home automation， enterprise， and industrial markets. In scenarios where contextual awareness like navigation and pin-point location are crucial – such as hassle-free airport navigation experiences， asset tracking of warehouse inventory， emergency response， even smart city infrastructure that helps the visually impaired be more mobile – Bluetooth 5 will send custom information people actually find useful in that moment without connection and application barriers.

　　Added Powell， “Today， there are 8.2 billion Bluetooth products in use， and the enhancements in Bluetooth 5 and planned future Bluetooth technical advancements mean that Bluetooth will be in more than one-third of all installed IoT devices by 2020. The drive and innovation of Bluetooth will ensure our technology continues to be the IoT solution of choice for all developers. ”

　　The addition of the Bluetooth SIG’s 30，000th member company shows that more and more companies are choosing Bluetooth as both the technology and the organization that will help them develop IoT products and services with the best consumer experiences and help bring those products and services to market faster and more successfully. Membership has grown over 11 percent since the end of 2015， now reaching a record-high with its 30，000th member， Blossom Group. The startup， which is building infrasound and low-frequency noise relaxation products， is just the latest validation that companies of all sizes and verticals are joining the SIG because the organization is working in collaboration with its members to advance the technology and make the world smarter， safer， better， and more enjoyable.

　　“Implementing Bluetooth as our wireless technology and joining the SIG organization was the obvious choice to ensure our products’ success，” said Luke Sanger， CEO and co-founder of Blossom Group. “Bluetooth has the ubiquity of a trusted wireless communication platform and a great history of supporting market trends and working with developers and members to produce ground-breaking products and applications. We know Bluetooth will stay ahead of the game by working with its members and embracing technological advancements – from power efficiency to IoT connectivity – to push the limits of innovation.”
