The annual China Hi-tech Fair (Hi-tech Fair) is held in Shenzhen, China, from November 16th to November 21st each year. Since it was first approved by the State Council in 1999, each year of the Hi-tech Fair will be national business. Departments, the State Intellectual Property Office and other government departments co-sponsored. After 17 years of continuous development and innovation, the Shenzhen Hi-tech Fair has become a major influence on the international science and technology arena. The Hi-tech Fair, also known as the "China Science and Technology Exhibition," is currently the most comprehensive, strongest, and most influential technology exhibition in China. Every year, many high-tech companies from all over the country and overseas come to the exhibition. The IT technology and product exhibition is the largest professional product exhibition at the High-tech Fair. This year, the theme is "Innovation IT, Outstanding Future". The scope of coverage includes virtual reality, smart manufacturing, smart wear, internet of things, smart home, The exhibitors of next-generation information technology, such as big data and mobile Internet, will see more professional and innovative technology products emerge here. Virtual Reality (VR), which took over 2 billion U.S. dollars from Facebook in 2014 to acquire Oculus, became the subject of constant discussion today: technology, future, subversion, and more. But to really fall into the details, what kind of form should VR be presented in people's perspective? This year's High-Tech Fair, the field of virtual reality is still an indispensable and important role. It is understood that the exhibitors of the VR industry participating in the High Fair this year also broke through the previous number and ushered in a new peak. From the outbreak of concepts to the formation of industries, many companies that have been immersed in the field of virtual reality for many years have brought this through the platform of the High-Tech Fair. The core technology and products of their own, with the on-site display and contact to further promote VR technology conversion, landing. In addition to the numerous virtual reality exhibitors, the organizers of the Hi-tech Fair also held a summit forum like 2016 Global Virtual Reality Industry to bring together the participants of the virtual reality industry ecosystem to achieve seamless communication and exchange. Judging from the above signs, this year's High-Tech Fair will once again become a grand feast for the virtual reality industry.

International standards of POE Switch: Poe Port,Poe Switch,Switch With Poe,Poe Power Supply Switch Shenzhen GL-COM Technology CO.,LTD. , https://www.szglcom.com
POE is also known as a local area network-based power supply system (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.
IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings of this standard have been restricting the expansion of the market. Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables. The method of power supply for points and other equipment is regulated. The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The 802.3at standard output power can reach 30W, and the available power at the receiving end is 25.5W.
The IEEE 802.3 working group and various manufacturer alliances launched POH-POWER OVER HDBASET in the industry at the end of 2012.
Using the current 4-Pair four-pair technology plus, the bilateral power supply can reach 60-100W power, which can be achieved by using Category 5 or 6 cables. It is used in high-definition video promotion to supply power to 42" LED TVs. According to the new regulations in 2010, the power consumption of 42" LED TVs needs to be less than 70W.
The production of 4-Pair four pairs of wires in China is low, so the industry with a long-term perspective should have the technology to upgrade from POE+ to POH as soon as possible!
