By contrast, BLE is a low power version of Bluetooth, meant for power sensors and accessories. Bluetooth Classic is used to connect mobile phones to Bluetooth headsets for phone calls and for streaming applications such as audio streaming and file transfers. Version 4.2 supports both Bluetooth Classic and Bluetooth Low Energy (BLE). Launched in December 2014, Bluetooth 4.2 introduced the IPv6 protocol, the most recent version of the Internet Protocol, for direct internet connection. In this article, we take a closer look at Bluetooth 5.0 support across today’s most popular mobile devices (Apple and Android), and offer those in the medical device industry guidance on when it makes sense to support Bluetooth 5.0 for your connected medical device(s). While it’s easy to take a “newer is better” approach in your development strategy, determining which version of Bluetooth to support requires a nuanced understanding of smartphone market share, user preferences, and upcoming smartphone trends: if your support goes too far back, you risk losing key Bluetooth benefits conversely, developing too far into the future means you risk losing important market share. Currently, the majority of devices with Bluetooth-connected mobile apps utilize Bluetooth 4.2 however, Bluetooth 5.0 offers several notable improvements over its predecessor and is rapidly gaining market share. Two versions of Bluetooth are now available for Apple and Android devices: Bluetooth 4.2 and Bluetooth 5.0. In this new space, wireless connectivity such as Bluetooth is powering the next-generation of IoE technologies - which, among its many use cases, has enabled patients to receive care via their smartphones. With over eight in 10 adults now owning a smart device, the “internet of everything” (IoE) has become more accessible to both patients and healthcare providers alike. In this article, we take a closer look at Bluetooth 5.0 support across today’s most popular mobile devices (Apple and Android), and offer those in the medical device industry guidance on when it makes sense to support Bluetooth 5.0 for your connected medical devices. Yet many consumers still don’t have Bluetooth 5.0 compatible smartphones. Implementers should be aware that the maximum transmit power level permitted under a given set of regulations might not be the same for all modulation modes.Bluetooth 5.0 introduces a number of upgrades in speed, security and range to previous versions of Bluetooth. * Devices shall not exceed the maximum allowed transmit power levels set by the regulatory bodies that have jurisdiction over the locales in which the device is to be sold or intended to operate. (3 advertising channels/37 data channels) Bluetooth LE now includes features that enable one device to determine the presence, distance, and direction of another device.Ģ.4GHz ISM Band (2.402 – 2.480 GHz Utilized) While initially known for its device communications capabilities, Bluetooth LE is now also widely used as a device positioning technology to address the increasing demand for high accuracy indoor location services. Bluetooth LE supports multiple communication topologies, expanding from point-to-point to broadcast and, most recently, mesh, enabling Bluetooth technology to support the creation of reliable, large-scale device networks. Transmitting data over 40 channels in the 2.4GHz unlicensed ISM frequency band, the Bluetooth LE radio provides developers a tremendous amount of flexibility to build products that meet the unique connectivity requirements of their market. The Bluetooth Low Energy (LE) radio is designed for very low power operation. The Bluetooth Classic radio also enables data transfer applications, including mobile printing. Supporting point-to-point device communication, Bluetooth Classic is mainly used to enable wireless audio streaming and has become the standard radio protocol behind wireless speakers, headphones, and in-car entertainment systems. The Bluetooth Classic radio, also referred to as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), is a low power radio that streams data over 79 channels in the 2.4GHz unlicensed industrial, scientific, and medical (ISM) frequency band.
