In CES2017, sporting industry still plays an important role of IoT industry.

Different from previous application acts as a monitoring device, self coaching becomes the highlight of this year.

As sporting becomes a worldwide fashion in recent years, go jogging, cycling, fitness now has become peoples’ part of life.

To help athlete improve performance easily and away from sports inquiry, correct

sporting movement is essential.

IoT industry combined with Bluetooth wireless industry now contribute the coaching service, which collected from big data and professional knowledge to make the works possible at home anytime anywhere.

What is BT4.1 and 4.2~ That is a frequent question for our customers.

Here, we quoted some information from SIG to help readers have easy understanding between different Bluetooth version.

BT4.1

This updated specification aims to improve consumer usability with increased co-existence support for LTE, efficient data exchange rates, and aid developer innovation by allowing devices to support multiple roles simultaneously.

Improving Usability—extends the brand promise to consumers with an “it just works” experience. This spec is engineered with several new features to make it work seamlessly with popular cell technologies like LTE, maintain connections with less frequent manual reconnection, and deliver a more efficient data exchange.
Empowering Developer Innovation—provides developers with greater flexibility to create innovative Bluetooth products and solutions through dual-mode topology and link-layer topology software features.
Enabling the Internet of Things—lays the groundwork for IP-based connections by allowing devices to setup a dedicated communication channel in the future thereby extending the central position for Bluetooth technology in the Internet of Things.

BT4.2

Key updates in 4.2 improve privacy and increase speed, and a soon-to-be ratified profile will enable IP connectivity.

Privacy and Security

Bluetooth 4.2 introduces industry-leading privacy settings that lowers power consumption and builds upon the government-grade security features of the Bluetooth specification. The new privacy features put control back into the hands of the consumer by making it difficult for eavesdroppers to track a device through its Bluetooth connection without permission. For example, when shopping in a retail store with beacons, unless you’ve enabled permission for the beacon to engage with your device, you can’t be tracked.

Speed

Bluetooth 4.2 increases the speed and reliability of data transfers between Bluetooth Smart devices. By increasing the capacity of Bluetooth Smart packets, devices transfer data up to 2.5 times faster than with previous versions. Increased data transfer speeds and packet capacity reduces the opportunity for transmission errors to occur and reduces battery consumption, resulting in a more efficient connection.

Internet Connectivity

Building on the capabilities released earlier with Bluetooth 4.1 and the new features released in 4.2, the Internet Protocol Support Profile (IPSP) will allow Bluetooth Smart sensors to access the Internet directly via IPv6/6LoWPAN. IP connectivity makes it possible to use existing IP infrastructure to manage Bluetooth Smart “edge” devices. This is ideal for connected home scenarios that need both personal and wide area control. This profile will be ratified by the end of the year.

Simple Summary

Scheduled to be released in end or 2016 or early 2017

1.Quadruples range

Extending range will deliver robust, reliable Internet of Things (IoT) connections that make full-home and building and outdoor use cases a reality. The expect power consumption of BT5 is expected to remain the same level as BT4.2.

BT4.2: 10~100M

BT5.X: Upto 400M

2.Doubles speed

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.

BT4.2: 1M bit/Sec

BT5.X: 2M bit/Sec

3. Data broadcasting capacity by 800%

Bluetooth 5,will quadruple range and double speed of low energy connections while increasing the capacity of connectionless data broadcasts by 800%.

According to SIG’s news press

“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”

“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."

To redefine the behavior of moving away from app-paired-to-device model must bring a revolutionary user behavior and environment from 2017. That is the most critical point for all product design or related Bluetooth industry need to pay highly attention!
