These three application areas will become the key targets of Bluetooth 5.0.

Bluetooth 5 new standard on the road, targeting in the smart home, Internet of Things (IoT), audio and other three applications. End product manufacturers must replace the chip to meet the latest standards. Does the new Bluetooth standard have an effect on the Internet of Things? What should I pay attention to when designing and developing products? What do I need to comply with for Bluetooth authentication? The following will be explained one by one.

As mobile phones become the most adhesive 3C products for consumers, using mobile phones as the IoT control center to drive other peripheral products is the main goal of this Bluetooth 5 standard. The Bluetooth SIG official website estimates that one out of every three wireless products produced by 2020 will use Bluetooth technology. According to Lux Insights, Inc.'s 2016 statistics, the global recognition of Bluetooth technology has reached 92%.

Bluetooth and other wireless transmission standards have been in a state of competition, but the biggest advantage of Bluetooth is that each mobile phone has Bluetooth function. When the standard is revised, each mobile phone will connect quickly, because each mobile phone chip vendor will support the latest. The Bluetooth standard allows other home appliances or peripheral products controlled by mobile phones to incorporate new technologies, and the new standard can transmit farther distances. Therefore, sensors that originally meet the Bluetooth low energy standards are bound to upgrade.

The Bluetooth standard distinguishes between traditional Bluetooth and low-energy Bluetooth standards. This new standard is based on the low energy consumption standard. The data speed, distance, and broadcast (broadcasTIng) data are increased by 2 times, 4 times and 8 times respectively, especially for the ConnecTIonless communication method. Strengthen the application scenario of automatic control in the Internet of Things, that is, the one-way transmission of trace information between the controller and the sensor.

In terms of IoT wireless transmission technology, the biggest impact of the new version of the Bluetooth 5 release is the Zigbee standard, which is also a low-energy, close-range small transmission. In the past, pairing a Bluetooth device with a mobile phone often caused a disconnection or poor reception due to the user bringing the mobile phone or tablet to another room. The Bluetooth 5 standard increased the transmission distance by 4 times, and the consumer can control the smart at any place in the home. Electric lights, smart door locks, smart air conditioners, home security equipment, etc. Transmission distances are comparable to Wi-Fi, but they are more power efficient than Wi-Fi, making it a new choice for location-related applications. As for wearable devices that transmit trace data, such as smart watches that can record and transmit pulse rate, walking number, heart rate, sleep situation, or intelligent temperature controllers that control temperature and humidity control air conditioners, can Bluetooth 5 develop new equipment for wearable devices? The bureau has a decisive influence.

There are already chips that comply with the Bluetooth 5 standard. Whether it is Qualcomm (Qualcomm) or MediaTek, the world's largest mobile phone chip maker, although they only sell chips, they will make a complete application of a complete mobile phone in order to ensure that the chip is not problematic. Once certified, the chip, hardware, and software are passed at the same time, and the entire set of reference designs can be provided to the customer when the chip is sold.

Going back to the product side, the product side must comply with Bluetooth 5. If you use an approved Bluetooth chip and have been tested and certified by an authorized organization, in general, there will not be too many testing problems. Germany Rhein suggested that product design developers should focus on the user's application side, thinking about how to take advantage of the advantages of Bluetooth 5 and new features, create product advantages, and highlight product differences. For example, the number of Bluetooth 5 broadcast data is increased by 8 times to 256 bytes per second. The speed is slower than dialing up the Internet in ancient times, but for the Bluetooth-based LBS (LocaTIon Based Service) targeted advertising in stores and stores. However, it can make the content of the Bluetooth push advertisement more rich and interesting.

Bluetooth enhanced LBS positioning application, LBS drives IoT growth

Bluetooth 5 is a broadcast (broadcasTIng) communication mode, which does not require online settings, so it is very suitable for LBS (targeting service) product applications. According to a survey by ABI Research, more than 371 million Bluetooth Beacons (via Bluetooth technology-targeted messaging services) will be shipped by 2020. Bluetooth 5 will help Beacons and LBS in the smart home, enterprise and industrial markets. Expand the application.

In addition, Bluetooth 5 does not require additional connection settings, is suitable for smart city infrastructure use, helps visually impaired people move in public spaces, or indoor positioning navigation path planning for parking lots, which are possible applications outside of retail advertising.

Germany Lein is the only third party in Greater China that can certify chips

Germany Lein is the first qualified BQTF laboratory in Greater China, and the only third-party testing agency in Greater China that can perform Bluetooth certification for chips. Since 2000, it has provided Bluetooth certification testing services, accumulated rich product experience and exclusive experience of Bluetooth protocol and Bluetooth protocol stack, which can effectively debug and solve product testing problems, and help enterprises to pass Bluetooth certification and cost-effectively. Multinational regulatory certification. Its Bluetooth Test Lab BQTF has full Bluetooth testing capabilities to provide RF RF, Bluetooth communication/application protocols and compatibility testing services for all Bluetooth standards.

In addition to the latest standards in Bluetooth 5, wireless products, whether laptops, phones, medical devices or other products, must go through local testing and verification processes in order to go on sale. for example:

North American market: FCC+IC

Any radio frequency product that is sold in North America must have a FCC (Federal Communications Commission) approval certificate in the United States and an IC (Industry Canada) radio approval certificate, such as a wireless network product, in Canada. Taiwan's Germany Rhein has become the United States Telecom Certification Agency (TCB) and the Canadian Foreign Certification Agency (FCB), which can provide services nearby.

European market: R&TTE/RED

The harmonized standards covered by R&TTE and RED wireless and communication directives are constantly being updated. If the products fall within the scope of the R&TTE and RED directives, they must pass the certification to assess whether the design of the product meets the harmonized standards. ETSI (European Telecommunications Standards Institute) has released a new applicable standard EN300328 v2.1.1 covering high power 2.4GHz short range equipment. For radio equipment operating in the 2.4 GHz band and complying with this standard, the importer will require the imported product to be tested according to the new EN300328 to comply with the requirements of the RED Directive.

Since RED is a new directive, vendors must retest their products for a limited time to comply with the new directives before they are mandatory in June 2017. The most important changes affect the receiver blocking test, which must now be done in normal data transfer mode. Germany's Rein has set up relevant test equipment and started to provide a new version of EN300328 v2.1.1 test service in February 2017.

In the European Union, the sale and operation of all radio products and telecommunications terminal equipment are governed by RED 2014/53/EC. Choosing a qualified laboratory for testing will ensure the safety, quality and functionality of the product and achieve one-stop cost-effectiveness.
