蓝牙5.0标准正式发布！距离300米 速度升2倍数据广播提升8倍！

6月17日消息，蓝牙技术联盟在伦敦正式发布了最新的蓝牙5.0技术标准。全新的蓝牙5.0标准将于今年年底或2017年年初正式推出，同时也会更新支持该标准的设备。官方表示，全新蓝牙5.0标准在性能上将远超目前的版本，也就是蓝牙4.2LE版本，包括在有效传输距离上将是4.2LE版本的4倍，也就是说，理论上，蓝牙发射和接收设备之间的有效工作距离可达300米。而传输速度将是4.2LE版本的2倍，速度上限为24Mbps。

同时，蓝牙5.0允许无需配对接受信标的数据，比如广告、Beacon、位置信息等，这一传输率提高了8倍。

另外，蓝牙5.0还支持室内定位导航功能，可以作为室内导航信标或类似定位设备使用，结合wifi可以实现精度小于1米的室内定位。这样，你就可以在那些非常大的商场中通过支持蓝牙5.0的设备找到路线。不过，在本次的发布中，蓝牙技术联盟并未提到这一项特性。另外，蓝牙5.0针对物联网进行了很多底层优化，力求以更低的功耗和更高的性能为智能家居服务。

蓝牙技术联盟执行总监Mark Powell 表示：“Bluetooth 5将使物联网连接变得更加简单无缝，颠覆人们的物联网体验。传输距离的提升将支持更多家居环境之外的物联网设备连接，速度的提升也将支持设备之间更迅速的信息传输与软件升级。此外，有了更强的广播信息传输能力，Bluetooth 5将会促进Beacon、位置感知，以及其他“无连接式”服务的发展，从而提供简易而无缝的物联网使用体验。”

Bluetooth 5预计于2016年末至2017年初发布，其在低功耗连接的距离与速度将各自提升4倍和2倍，而无连接式的广播数据传输量將提升八倍。除此之外，它還能保持业界领先的功耗表現。 伴随着数据传输量的大幅提升，而可被传输的数据将更加丰富且更智能化，将重新定义蓝牙设备传输信息的方式，从“设备配APP”模式转变成一种“无连接式”的物联网模式，减少下载应用程序或应用程序与设备连接的需求。

调研机构ABI Research首席分析师Patric Connolly介绍，至2020年，基于蓝牙的Beacon出货量预计将超过3.71亿。凭借广播数据传输量八倍的提升，Bluetooth 5将进一步推进Beacon和定位服务在智能家居、商业和工业市场中的应用和部署。在极度仰赖场景感知能力如导航和跟踪定位等情境中，Bluetooth 5无需设置连接或应用，就能向人们发送当下非常有用的定制化信息。例如，机场无障碍导航体验、库房库存资产追踪、应急响应，乃至能够辅助视觉障碍人群出行的智慧城市基础设施等。

Powell表示：“目前全球已有多达82亿个蓝牙产品正在被使用中，而Bluetooth 5的性能提升与未来蓝牙的发展规划让我们有理由相信，到2020年，超过三分之一的物联网设备都将采用蓝牙技术。蓝牙的驱动力和的创新能力将确保它是所有开发者在创建物联网解决方案时的最佳选择。”

第30,000家会员公司的加入，证明蓝牙技术联盟受到越来越多公司的信任，支持企业在开发物联网产品服务时为消费者带来最佳体验，将产品和服务快速推向市场，并取得成功。蓝牙技术联盟成员数量规模自2015年底至今增长超过11%，第30, 000名会员Blossom Group的加入使这个数字再创历史新高。这家研发次声波和低频降噪产品的新创公司的加入，进一步彰显了各种规模、类型及垂直行业加入蓝牙技术联盟的积极态势。蓝牙技术联盟正是通过与这些机构携手，不断推进技术发展，让世界变得更加智能、安全、美好、愉快。

Blossom Group 首席执行官兼联合创始人Luke Sanger表示：“选用蓝牙无线技术，并加入蓝牙技术联盟是确保我们产品成功的必然之选。蓝牙不但拥有无处不在、值得信赖的无线通信平台，并且一直以来紧跟市场趋势，与开发者和会员公司一同携手开发具有独创性的产品和应用。我们相信蓝牙会继续保持与其联盟成员的紧密合作，不断实现从功耗到物联网连接的各种技术创新，突破进取，永远先人一步。”

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.”
