The problem of inconsistent communication technologies has long plagued the Internet of Things industry. Communication technologies such as Wi-Fi, Bluetooth, and ZigBee are constantly trying to increase their penetration in the Internet of Things area with their respective advantages.
At the recent wireless communication technology summit held in Shenzhen, Zig Bee Alliance Chinese member chairman Su Weimin introduced the latest developments of ZigBee 3.0, and CEO Nanyang Lienun CEO tension from the domestic leading Internet of things one-stop solution From the perspective of the solution provider, the concept of IoT communication technology has broken through the opportunities, and its conclusions are of reference value.
IoT communication technology is difficult to unify, benefits and habits are two big mountains
"Just just told us about the latest developments in ZigBee 3.0, and many of these improvements are gratifying." Tension believes that ZigBee 3.0 has an important improvement over the previous 2.0 version, and it has developed a complete set of application layers at OSI. specification. Companies that choose to use the ZigBee 3.0 full-definition specification will be able to recognize each other's capabilities in the ZigBee 3.0 network. This will truly enable cross-brand and cross-category interconnection of IoT products. "This is a historic one." progress".
However, even if ZigBee 3.0 has such a powerful function, it is still an impossible task for the IoT. Sinan Wulian is a leading one-stop solution provider for the Internet of Things and has cooperated with many traditional enterprises in the fields of industry, agriculture, commerce and energy grids, and home appliances. In numerous project dockings, Si Nan Wulian found that it is not important for traditional enterprises to use what kind of technology to achieve interconnection. The most important thing is that the application of these technologies must be stable enough and can be combined with existing products/systems. Perfect collaboration.
"RF315/433 technology has been used in the security field for more than 30 years. The entire security industry is using this technology, including some banking systems. Similarly, Bluetooth and WI-FI also have their own strong application areas." Tension stated that many communications Technology has formed deep-rooted influence in their respective traditional application fields, and the corresponding entire industrial chain is providing realization and support for these technologies. The new communication technology wants to enter these fields, not only to convince the industry chain to change completely upstream and downstream, but also to allow customers to accept the hidden dangers of the new technology in terms of compatibility, stability, etc., the difficulty is very great. For customers who value these issues in particular, they often prefer to stick to old technologies and systems rather than risk adopting new technologies.
When the communication technology enters new application fields, it not only has to face the obstacles formed by the upstream and downstream of the industrial chain based on its own inherent interests and habits, but also interest groups behind different communication technologies often have the notion of being incorrect or not cooperative. As a result, not only is information transfer and technology integration difficult to implement, but a single communication technology is also prone to serious short-sightedness and quick success. "For example, the Z-Wave chip is controlled by an upstream company, and it is often unacceptable for a cautious company to subject its own product to an irreplaceable supplier."
At the current stage, product interoperability needs to be achieved, and the composite gateway is the breakthrough
So, since in the huge market of IoT, every wireless communication technology cannot eat other competitors in the short term, how should industry companies break the barrier between communication technologies and realize the inter-brand interconnection of IoT devices? ? On this point, after the seminar was over, tensions revealed an important answer to the author.
"We have recently been planning a heavyweight project, which involves problems in this area." Tension said. "We believe that at the present stage, due to the complexity of network bandwidth and protocol identification, the most appropriate way to achieve product continuity is to start with the LAN gateway of the end customer."
Si Nan Wulian believes that the Internet of Things terminals that are purchased by end customers and belong to different brands and communication technologies can be easily interconnected and interoperable. At this stage, composite gateways should be provided as a compromise solution. This "composite" has two meanings, that is, the combination of communication technology and cloud platform. "Comprehensive communication technology is easy to understand, is that the same gateway supports a variety of different communication technologies, such as ZigBee, Wi-Fi, Bluetooth, etc., from the basic level of communications integration of different products to form a unified system." Tension introduced. The compounding of the cloud platform means that the gateway accesses multiple cloud platforms at the same time, and indirectly realizes the interconnection of different products by accessing the cloud platform to which the user's products belong.
Re-discussion on communication technology: Integrity of the bottom layer, direct networking, and specification
Composite gateways are a viable way of achieving product interconnection and interoperability in the short term, but in the long term, if there is no IOT technology that dominates the world, can we tell which technologies are more viable? On this point, tension also gives the answer.
"Communication technologies with more adaptability in the Internet of Things must be at the bottom of the Internet to meet the requirements of the Internet of Things. This is the same as the processor. Intel has dominated the PC field for many years, but the embedded space has long been ARM is the world.This is determined by the inherent differences between the two processor products.ARM processor based on RISC architecture, instructions and pipeline length is much smaller than the Intel processor of the CISC architecture, so the latter is a huge effort to improve but power consumption It's still high."
At present, Google's Thread, Bluetooth 4.2 and ZigBee3.0 are all very advanced communication technologies. They all have relatively complete specification of the communication process since the data link layer, and have gone deeper than IP in the OSI model. The deeper aspect of the agreement lays the foundation for its later development into a more complete and powerful communication protocol than the IP protocol. At the same time, they are also relatively complete in terms of the integrity of the specification, and can therefore be well implemented for different products under the same technology. Mutual recognition of interconnection and mutual control; Finally, their ability to support IP communications are both excellent, while still increasing. Since the Internet of Things still uses the traditional IP network as the backbone network, the vitality of communications technologies supporting IP communications in the field of Internet of Things will obviously be stronger.
In the area of ​​Internet of things, everyone knows the importance of unified communications technology, but if there is no strong enterprise to promote, this process must be slow; the process is just like tension: "If we look back at the IT industry The history of development will reveal that the advanced nature of technology has never been the only factor that promotes its widespread application. Only when a technology is widely used as a de facto standard does it truly dominate the industry. When a technology is applied in a field for a long time, it will become very difficult to replace it."
