6月17日消息，藍(lán)牙技術(shù)聯(lián)盟在倫敦正式發(fā)布了最新的藍(lán)牙5.0技術(shù)標(biāo)準(zhǔn)。全新的藍(lán)牙5.0標(biāo)準(zhǔn)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(biāo)準(zhǔn)的設(shè)備。官方表示，全新藍(lán)牙5.0標(biāo)準(zhǔn)在性能上將遠(yuǎn)超目前的版本，也就是藍(lán)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(lán)牙發(fā)射和接收設(shè)備之間的有效工作距離可達(dá)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(lán)牙5.0允許無需配對接受信標(biāo)的數(shù)據(jù)，比如廣告、Beacon、位置信息等，這一傳輸率提高了8倍。

　　另外，藍(lán)牙5.0還支持室內(nèi)定位導(dǎo)航功能，可以作為室內(nèi)導(dǎo)航信標(biāo)或類似定位設(shè)備使用，結(jié)合wifi可以實現(xiàn)精度小于1米的室內(nèi)定位。這樣，你就可以在那些非常大的商場中通過支持藍(lán)牙5.0的設(shè)備找到路線。不過，在本次的發(fā)布中，藍(lán)牙技術(shù)聯(lián)盟并未提到這一項特性。另外，藍(lán)牙5.0針對物聯(lián)網(wǎng)進(jìn)行了很多底層優(yōu)化，力求以更低的功耗和更高的性能為智能家居服務(wù)。

　　藍(lán)牙技術(shù)聯(lián)盟執(zhí)行總監(jiān)Mark Powell 表示：“Bluetooth 5將使物聯(lián)網(wǎng)連接變得更加簡單無縫，顛覆人們的物聯(lián)網(wǎng)體驗。傳輸距離的提升將支持更多家居環(huán)境之外的物聯(lián)網(wǎng)設(shè)備連接，速度的提升也將支持設(shè)備之間更迅速的信息傳輸與軟件升級。此外，有了更強(qiáng)的廣播信息傳輸能力，Bluetooth 5將會促進(jìn)Beacon、位置感知，以及其他“無連接式”服務(wù)的發(fā)展，從而提供簡易而無縫的物聯(lián)網(wǎng)使用體驗?！?/p>

　　Bluetooth 5預(yù)計于2016年末至2017年初發(fā)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(shù)據(jù)傳輸量將提升八倍。除此之外，它還能保持業(yè)界領(lǐng)先的功耗表現(xiàn)。 伴隨著數(shù)據(jù)傳輸量的大幅提升，而可被傳輸?shù)臄?shù)據(jù)將更加豐富且更智能化，將重新定義藍(lán)牙設(shè)備傳輸信息的方式，從“設(shè)備配APP”模式轉(zhuǎn)變成一種“無連接式”的物聯(lián)網(wǎng)模式，減少下載應(yīng)用程序或應(yīng)用程序與設(shè)備連接的需求。

　　調(diào)研機(jī)構(gòu)ABI Research首席分析師Patric Connolly介紹，至2020年，基于藍(lán)牙的Beacon出貨量預(yù)計將超過3.71億。憑借廣播數(shù)據(jù)傳輸量八倍的提升，Bluetooth 5將進(jìn)一步推進(jìn)Beacon和定位服務(wù)在智能家居、商業(yè)和工業(yè)市場中的應(yīng)用和部署。在極度仰賴場景感知能力如導(dǎo)航和跟蹤定位等情境中，Bluetooth 5無需設(shè)置連接或應(yīng)用，就能向人們發(fā)送當(dāng)下非常有用的定制化信息。例如，機(jī)場無障礙導(dǎo)航體驗、庫房庫存資產(chǎn)追蹤、應(yīng)急響應(yīng)，乃至能夠輔助視覺障礙人群出行的智慧城市基礎(chǔ)設(shè)施等。

　　Powell表示：“目前全球已有多達(dá)82億個藍(lán)牙產(chǎn)品正在被使用中，而Bluetooth 5的性能提升與未來藍(lán)牙的發(fā)展規(guī)劃讓我們有理由相信，到2020年，超過三分之一的物聯(lián)網(wǎng)設(shè)備都將采用藍(lán)牙技術(shù)。藍(lán)牙的驅(qū)動力和的創(chuàng)新能力將確保它是所有開發(fā)者在創(chuàng)建物聯(lián)網(wǎng)解決方案時的最佳選擇。”

　　第30，000家會員公司的加入，證明藍(lán)牙技術(shù)聯(lián)盟受到越來越多公司的信任，支持企業(yè)在開發(fā)物聯(lián)網(wǎng)產(chǎn)品服務(wù)時為消費(fèi)者帶來最佳體驗，將產(chǎn)品和服務(wù)快速推向市場，并取得成功。藍(lán)牙技術(shù)聯(lián)盟成員數(shù)量規(guī)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(shù)字再創(chuàng)歷史新高。這家研發(fā)次聲波和低頻降噪產(chǎn)品的新創(chuàng)公司的加入，進(jìn)一步彰顯了各種規(guī)模、類型及垂直行業(yè)加入藍(lán)牙技術(shù)聯(lián)盟的積極態(tài)勢。藍(lán)牙技術(shù)聯(lián)盟正是通過與這些機(jī)構(gòu)攜手，不斷推進(jìn)技術(shù)發(fā)展，讓世界變得更加智能、安全、美好、愉快。

　　Blossom Group 首席執(zhí)行官兼聯(lián)合創(chuàng)始人Luke Sanger表示：“選用藍(lán)牙無線技術(shù)，并加入藍(lán)牙技術(shù)聯(lián)盟是確保我們產(chǎn)品成功的必然之選。藍(lán)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(fā)者和會員公司一同攜手開發(fā)具有獨(dú)創(chuàng)性的產(chǎn)品和應(yīng)用。我們相信藍(lán)牙會繼續(xù)保持與其聯(lián)盟成員的緊密合作，不斷實現(xiàn)從功耗到物聯(lián)網(wǎng)連接的各種技術(shù)創(chuàng)新，突破進(jìn)取，永遠(yuǎn)先人一步?！?/p>

　　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.”
