In recent years, in addition to the popularity of portable devices and wearable devices, another new trend that has emerged in the past - smart homes , from the original situation of thunder and heavy rain, began to catch everyone's attention. At this year's Consumer Electronics Show (CES), many technology giants participated in the event and showed how to introduce and integrate digital audio and video content into real life. It is worth noting that hardware brand manufacturers have begun to pay attention to the integrity of content services. It is expected that under the integration of software and hardware, the industrial ecosystem will be more stable, and it will have a multiplier effect on the promotion of comprehensive effects.
According to IDC, the market research organization, the smart home market is estimated to have a compound annual growth rate of 17.74% from 2013 to 2020. It is estimated that by 2020, it will be expected to see a market size of 51.77 billion US dollars. After the end of the CES, it is expected that there will be a significant growth in the smart home device market in 2014, including the telecom industry and cable operators' attitudes towards the smart home application service are expected to turn positive. As a professional testing laboratory, we have cooperated with many related manufacturers to enter the smart home market. Therefore, we hope that through this article, we can briefly introduce the current state of the art, the key points that manufacturers need to pay attention to when developing products, and the future. Market direction.
There are many technologies on the market that are used in smart homes, such as Z-Wave, ZigBee, AllSeen, LightwaveRF, and InsteOn... each with its own advantages and disadvantages. In this article we will lock on three focus technologies:
â—Z-Wave
â—ZigBee
â—AllSeen
Table 1: Parameters and comparison of ZigBee, Z-Wave and AllSeen
As shown in Table 1, Z-wave and ZigBee are based on the technology developed on the radio frequency, belonging to the hardware architecture and protocol technology. Z-wave is a technology independently developed by SigmaDesign, but it lacks international standards to rely on it. The application is only limited to home automation. Different from ZigBee, it can be used in medical and security fields. ZigBee is a protocol built on IEEE802.15.4 with a wide application level. Although both technologies are based on WirelessSensorNetworks (WSN), Z-wave is more focused on smart home applications; ZigBee has developed a number of protocols that are currently used in smart grids and smart buildings in addition to smart homes. on. Although both ZigBee and Z-Wave are connected in series with similar wireless network technologies, hundreds of products support the use of these two technologies. However, at this stage, there is a market phenomenon of multi-horse carriages, and there is no single technology phenomenon.
The AllSeen Alliance (AllSeen Alliance), which is jointly organized by LG, Qualcomm and Sharp, is based on AllJoyn, an open source code platform developed by Qualcomm. It develops AllSeen technology and is a simple protocol specification. hardware design. The concept at the outset was based on the TCP/IP network protocol, which developed a concept similar to UPnP and DLNA, allowing hardware devices to reach the controllable targets via Wi-Fi, wire or Ethernet connections through the AllSeen protocol. The concept of practicing smart home is in daily life.
