OFweek smart home network to rely on the Internet of things, smart home industry has developed rapidly. According to forecasts, the global smart home market is expected to exceed 100 billion U.S. dollars in 2017, with a compound annual growth rate of around 20%, and the potential is very large. Faced with such a huge market "cake", at present, both the upper reaches of the semiconductor business, or the middle and lower reaches of the product plan designers, are rushing to layout smart home, with the intention to shake the Blue Ocean.
At this stage, the biggest characteristic of the development of smart homes is that wireless communication protocol standards are different, and diversified protocols are blooming everywhere. As the pioneer of Bluetooth 5.0, WiFi, ZigBee first occupied most of the market, followed by Thread, Macbee, Homekit as a new force strong debut, to the current wireless communications field impact, or will change the market.
ZigBee, Bluetooth 5.0, WiFi is not a big deal
All along, domestic smart lighting market agreements are diversified and differentiated. ZigBee, Bluetooth 5.0, WiFi three major communication protocols to control most of the market share, have their own advantages, is the preferred choice for most manufacturers.
Zigbee
Since 2002, the zigbee Alliance and its member companies have been working to create standards, certification programs, and testing tools for building low-power wireless Internet of Things (IoT) interoperable products. The number of devices that have used the zigbee standard so far has exceeded one billion in the world.
As a wireless communication technology, although zigbee can only be used in networks with low speed, static, high node density, or low data transmission control, and can not be directly controlled by a smart phone, it also needs to pass an additional gateway. It can be said that there are a lot of leaks, but due to its features such as low power consumption, low cost, short delay, large network capacity, and safety and reliability, together with the promotion of Philips and OSRAM, it has been used by more and more mainstream manufacturers.
Bluetooth 5.0
Compared with ZigBee, Bluetooth 5.0 has little difference and it also occupies part of the market.
Bluetooth 5.0 is a new Bluetooth standard released on June 16, 2016 by the Bluetooth Special Interest Group. Compared to Bluetooth 4.2, Bluetooth 5.0 has a comprehensive improvement, whether it is communication speed, communication distance or communication capacity has greatly improved. Compared with other wireless technologies such as wireless 2.4G and WiFi, Bluetooth has many advantages such as perfect encryption, stable transmission process, and rich compatible devices.
While wireless communication protocols are blooming all over the place, Bluetooth 5.0 is able to spread almost all digital devices to allow wireless communication between various digital devices. It is with such a powerful feature that Bluetooth 5.0 occupies a lot of the wireless communications market, becoming the choice of most enterprise manufacturers.
WiFi
The Internet of Things has landed on smart homes and there are many agreements. The most successful one is WiFi.
The advantage of the WIFI technology lies in the high radio wave coverage (100m), high network speed, good mobility, and low entry barriers for manufacturers. However, the WiFi protocol is used in smart lighting. The number of connected items is more than one. The stability of the connection is highly tested and the penetrability problem remains to be solved. At the same time, Wifi has a higher bandwidth at the expense of increased power consumption. Therefore, portable WIFI devices require higher power reserves, which limits the promotion of smart lighting applications.
Macbee, Thread, Homekit have a strong debut
Bluetooth 5.0, WiFi, and ZigBee are the most popular wireless communication protocols in the current smart home industry. Although they have many shortcomings and limitations, they have always been the focus of most manufacturers. At the same time, some other wireless communication protocols carry bright spots and are strongly entering the wireless communications market.
MacBee
MacBee is a communication protocol implemented by Galaxy to solve the smart home communication problem. While realizing the smart home function, it helps many lighting companies realize the intelligent control of lighting. As an ultra-low-power micro-cellular wireless IoT communication protocol, MacBee adopts a multi-protocol compatible ad hoc network bi-directional linkage technology framework from the cloud to the application to connect to global unified standards. The service architecture is global, real-time, and high. Reliable and efficient features, but also with high cost performance.
Chairman of the Galaxy and Chairman of MacBee Technology Alliance Zeng Yu pointed out at the third China IOT Conference that "Bluetooth is for headsets, WiFi is for mobile phones and laptops, ZigBee is for M2M, and MacBee is for family. The Internet of Things is born. "At present, in addition to video transmission using WiFi, all other smart home devices use MacBee's wireless two-way networking technology, including lighting, electrician, security, curtains, door locks, home appliances, etc. Sensors and other applications. According to Zeng Yu, the current MacBee chip sales have exceeded 30W, and are still growing. It is expected that 10 to 20 million connections will be generated after landing in 17 years.
The application of MacBee technology to the smart home system needs to make a breakthrough, or it will bring impact to the current wireless communication field. At the same time, it will also bring better and better choices to smart home companies that are still hesitant in wireless communication protocols.
Thread
Similar to Zigbee, Thread is also developed based on a low-cost, low-power 802.15.4 chipset. It is a new generation of IP-based wireless mesh network protocol standard that supports low-power connections, hundreds of node controls, and Reliable information security protection. Thread can not only give each network node a specific IPv6 address, but also establish a direct connection with the gateway. It also has the self-healing function and will not be affected by any one of the failed nodes.
Of particular note is that the Threadless Wireless Mesh Network architecture achieves very low control signal delays and is superior to ZigBee, which is also a mesh network topology. At the same time, due to the similar development background, many products that are currently using Zigbee can support Thread with a simple software upgrade. It is very easy to install and can be extended to hundreds of devices; but it is different from Zigbee, the Thread standard. Unification, unlike Zigbee's products, is due to the fact that different manufacturers have different implementations, resulting in incompatibility between different products. This is also arguably the advantage of Thread over Zigbee.
It can be said that Thread can help designers more easily realize the real-time control of a large number of lamps, and can add more ideas for IoT lighting to accelerate the arrival of the smart home era.
HomeKit
As the gateway of smart homes, wireless communications have triggered a battle for business, and Apple is not to be outdone. In June 2016, Apple released iOS 10 system built-in native smart home control HomeAPP, can use Siri for smart home voice control, will open its smart home open platform HomeKit to the public view.
Different from ZigBee, Bluetooth 5.0, WiFi, Macbee, Thread, etc., HomeKit provides a more ideal way for smart home - voice interaction.
The Apple HomeKit platform uses the voice assistant Siri as a function to implement the entry point. The user can use the "Automation" setting in Apple's Native HomeApp to edit common scenes of all smart products that access the HomeKit platform, such as "go home, leave home, Good morning, good night, etc., through a command to enable a variety of smart devices to work together. That is, all smart devices that access the HomeKit platform, such as lights, switches, sockets, thermostats, windows, fans, air conditioners, and sensors, form a complete smart home system. The user's voice can become an input command, for example, saying "Hey, Siri I'm home," and the home is on. In addition, users can also share control rights with other family members, which enables collaborative management of smart home devices.
It can be said that HomeKit is a milestone in the evolution of smart homes from functional realization to interactive experience. Its voice sound control provides a more feasible development direction for the smart home industry.
Who is ultimately determined by the market?
As the chairman of the Galaxy has said, each type of agreement arises because it satisfies the needs of a certain scenario. If an agreement can meet all the needs of the Internet of Things, then no other agreement will be born at all. In fact, each protocol will have its own best practice scenario.
The competition of today's smart home wireless communication protocols is like competing with each other on the Internet. It is believed that the future will be an era of development and integration. Hundreds of flowers flourish and various agreements may coexist. But who will become the mainstream and who will be replaced will ultimately be determined by the market. Of course, it is undeniable that Macbee, Homekit, and Thread are breaking out of the ZigBee, Bluetooth 5.0, WiFi-enabled market, or will bring significant changes to smart home wireless communications. As an intelligent lighting company, it is necessary to pay more attention to new wireless communication protocols and find better technical solutions for enterprise development.
