What will Bluetooth 5 be about

Bluetooth are to release the 5th major version of their wireless personal-network specification by between late 2016 to early 2017. But what will this offer?

This is more about increasing broadcast capacity, data bandwidth and operational range for Internet of Things applications while working with the unlicensed 2.4GHz ISM waveband. The extended range will be seen in the smart-home context as reaching beyond the walls of a typical house while there is the improved operational robustness affecting this class of application.

One of the key benefits is to reduce the need for “device + app” setup for Internet-of-Things setup. This typically requires that you go to the mobile platform’s app store to download a special “enablement” app for your Internet-Of-Things device to your smartphone or tablet and then logically associate that device with your mobile device before you can benefit from that device. This applies also to “beacon” setups where the venue has to develop a mobile-platform app to make sense of the beacons that they use for indoor navigation / location setups.

The question that could be raised is whether this will lead towards a “Web-app” setup where beacons and Internet-of-Things devices will run their own mobile Web pages for showing data about themselves or their current status. Similarly, could this also lead to the creation of a platform-detecting “interface page” which leads people to install mobile-platform apps from the correct mobile-platform app store.

There will also be the question about assuring the privacy and data security for end-users and their mobile client devices so as to prevent Bluetooth 5 beacons and IoT devices from being a malware-distribution vector. Here, it may be about implementing a “trust-based” system which is based on factors like suppliers, venues, software developers and the like. Similarly, it may be more valuable to have this kind of setup based around “pull-based” content acquisition where the end-user is involved in the process of acquiring the data rather than the data being automatically delivered to the end-user’s mobile device.

There are other use cases that can take advantage of this large data capacity in the context of beacons and the Internet Of Things especially if the “device+app” setup is still maintained. One of these would be to allow field-based software and data maintenance where a new Webpage or firmware could be supplied to a Bluetooth 5 IoT device from a mobile client. Similarly, you could upload and download operational data between the IoT device and a mobile client or portable computer with building security, data-logging or smartwatches being a key application. For example, it could be a simple and quick task to deploy a rich watch-face or app to a smartwatch while syncing data like contacts-lists and health data to your smartphone at the same time.

The Bluetooth 5 technology will benefit the smart-home, enterprise and industrial applications. Some of the use cases being called out in the form of indoor navigation for airports and shopping centres, asset or warehouse-inventory tracking, improved emergency response like the “enhanced 911” service that benefits mobile-phone users along with the ability to assist visually-impaired people around the cities. An advertising-based application may involve a beacon-type device at an event being used to provide further information like a PDF or HTML “e-brochure” hosted on that device.

Like with every evolution of the Bluetooth standard, this will require newer Bluetooth 5.0 compliant hardware on the client device and this will typically be provided with newer client devices after mid-2017. Regular computers could be upgraded to this standard thanks to USB Bluetooth modules which could be seen as a way to upgrade Windows laptops, 2-in-1s or tablets. This also applies to some embedded devices that provide some form of “after-the-fact” functionality upgrading like the Yale and Lockwood smart deadbolts that use a wireless-connectivity module for smart-home functionality.
