The problem of non-uniform communication technology has long plagued the Internet of Things industry. Wi-Fi, Bluetooth, ZigBee and other communication technologies continue to try to enhance their penetration in the Internet of Things field.
On April 8th, at the 3rd Wireless Communication Technology Summit hosted by electronic enthusiasts, Su Weimin, Chairman of the ZigBee Alliance China Member Group, introduced the latest developments of ZigBee 3.0, while the CEO of Sinan IOT was leading from the domestic market. The perspective of the one-stop solution provider of the Internet of Things has broken the secrets of the Internet of Things communication technology, and the conclusions are quite valuable.
Internet of Things communication technology is difficult to unify, interests and habits are two mountains
"I just talked about the latest developments of ZigBee 3.0, and many of them are gratifying." Tension said in his speech. He believes that ZigBee 3.0 has an important upgrade compared to the previous 2.0 version, and has developed a complete specification in the application layer of OSI. Selecting vendors that use the ZigBee 3.0 full definition specification, their products/systems can be mutually recognized in the ZigBee 3.0 network, thus truly realizing the interoperability of IoT products across brands and across categories. “This is a historic progress".
However, even with ZigBee 3.0 such a powerful feature, the Internet of Things is still an almost impossible task for it. Sinan IOT is one of the leading Internet of Things one-stop solution providers in the country, and has cooperated with many traditional enterprises in the fields of industry, agriculture, commerce and energy grid, and home appliances. In the numerous project dockings, Sinan IOT found that it is not important for traditional enterprises to use any technology to achieve interconnection. The most important thing is that these technologies are stable enough to be used and can be integrated with their existing products/systems. Achieve perfect synergy.
"RF315/433 technology has been used in the security field for more than 30 years. The security industry is using this technology, including some banking systems. Similarly, Bluetooth and WI-FI also have their own strong application areas." Tension indicates that many communications Technology has formed a deep-rooted influence in their respective traditional application areas, and the corresponding entire industry chain is providing implementation and support for these technologies. New communication technologies want to enter these fields, not only to convince the entire chain of upstream and downstream changes, but also to allow customers to accept the hidden dangers of new technologies in terms of compatibility and stability, the difficulty is very large. For customers who value these issues, they tend to prefer to stick to old technologies and systems, rather than risking new technologies.
When entering the new application field, communication technology must not only face the obstacles formed by the upstream and downstream of the industry chain based on its own inherent interests and habits. The interest groups behind different communication technologies often have the concept of incorrect or non-cooperative. In this way, not only information transmission and technology integration are difficult to achieve, but also a short communication and quick success in the promotion process of a single communication technology. “For example, the Z-Wave chip is controlled by an upstream company, and it is often unacceptable for a cautious company to subject its products to an irreplaceable supplier.â€
At this stage, we need to make product interconnection and interoperability, and the composite gateway is a breakthrough.
Then, since in the huge market of the Internet of Things, all wireless communication technologies can't eat other competitors in a short period of time, how should industry enterprises break the barrier between communication technologies and realize cross-brand interconnection of IoT devices? ? In this regard, after the seminar, tension revealed an important answer to the author.
“We have been planning a heavyweight project recently, which involves this issue.†Tension said. "We believe that at this stage, due to the complexity of network bandwidth and protocol identification, the most appropriate way to achieve product access is to start from the end customer's LAN gateway."
Sinan IOT believes that the Internet of Things terminals that are purchased and used by different customers and are affiliated with different brands and communication technologies can be easily interconnected. At this stage, a composite gateway should be provided as a compromise. The "composite" of this has two meanings, that is, the combination of communication technology and cloud platform. "Communication technology is easy to understand, that is, the same gateway supports a variety of different communication technologies, such as ZigBee, Wi-Fi, Bluetooth, etc., to integrate different products from the communication infrastructure level to form a unified system." Tension introduced. The combination of the cloud platform means that the gateway accesses multiple cloud platforms at the same time, and accesses the cloud platform to which the user products belong, thereby indirectly implementing interconnection and intercommunication of different products.
Re-discussion on communication technologies: underlying, direct networking, and integrity of specifications
Composite gateways are a viable way to achieve product interoperability in the short term, but in the long run, even if there is no IoT communication technology in the world, can we tell which technologies are more vital? In this regard, tension also gives the answer.
"Communication technology with more adaptability in the field of Internet of Things must be in line with the characteristics of the Internet of Things. This is the same situation as the processor. Intel has been the leader in the PC field for many years, but the embedded field has long been It is the world of ARM. This is determined by the innate differences in the processor products provided by the two. ARM processor based on RISC architecture, instruction and pipeline length is much smaller than the Intel processor of CISC architecture, so the latter consumes great effort to improve but power consumption Still very tall."
At present, Google's Thread, Bluetooth 4.2 and ZigBee 3.0 are very advanced communication technologies. They all have a relatively complete specification of the communication process from the data link layer. In the OSI model, it has been deeper than IP. The deeper level of the agreement lays the foundation for its later growth into a more complete and powerful communication protocol than the IP protocol. At the same time, they are relatively complete in terms of the integrity of the specification, so they can achieve different products under the same technology. Mutual recognition of interconnection and mutual control; in the end, their ability to support IP communications is excellent, and it is still growing. Since the Internet of Things still uses the traditional IP network as the backbone network, the communication technology supporting IP communication is obviously stronger in the field of Internet of Things.
In the field of Internet of Things, everyone knows the importance of the unification of communication technology, but if there is no strong enterprise to promote, this process must be slow; the process is as tension: "If we look back at the IT industry The history of development will reveal that the advancement of technology has never been the only factor driving its widespread use. Only when a technology is widely used as a de facto standard does it really dominate that industry. When a technology is applied to a field for a long time, it will become very difficult to replace it."
