Referring to the short-range wireless communication technology in the Internet of Things, many people may think of Bluetooth and WiFi in the first place. But in fact, other technologies, including Zigbee , are growing at a faster rate and quickly occupying the market. Since the beginning of the past few years, the domestic market has made a significant shift in the development attitude of Zigbee technology. More and more Chinese manufacturers have joined the Zigbee Alliance, including WULIAN, Huawei, and the United States, all of which have become members of the Zigbee Alliance. Zigbee technology development accelerates China's market attitude has changed significantly. The global Zigbee activation equipment market 2016-2020 report predicts that the global Zigbee activation equipment market will achieve a CAGR of 29.73% during 2016-2020. At the same time, more and more Chinese companies are joining the Zigbee Alliance. For the Zigbee Alliance, this is a big change, because in ...

Nowadays, the Internet has entered thousands of households, and the Internet has become an indispensable thing in life. Moreover, with the continuous improvement of the network speed and the development of “light into copper retreat”, most new residential communities and network users have now achieved fiber-to-the-home. In this way, the average network user will have several boxes at home, such as light cats, routers, network TV boxes, etc. Sometimes there is a failure, the user does not know how to distinguish, how to describe them, can not quickly and correctly declare obstacle. 1.Light cat Light cat is a common name. The modem from the early dial-up era, commonly known as the cat, is called a modem, and turns a digital signal into a device that transmits analog signals over a telephone line. After entering the era of optical network, the optical signal transmitted by the optical fiber arrives at home, and a device needs to be converted into an electrical signal to communicate wi...

At the "2018 China Optical Network Seminar", Jia Wu, senior engineer of the Optical Access Network Room of the Network Technology Research Department of China Unicom Network Technology Research Institute, pointed out that after the previous laboratory tests and field tests, China Unicom completed the FTTH of 10G PON . Interoperable technical reserves. In April 2018, China Unicom launched the collection and testing of different single-board OLTs such as XG-PON, Combo-PON and 10G EPON. The intercommunication function and performance test of multiple test cases have become mandatory requirements. Jia Wu said that it is expected that the FTTH of China Unicom's 10G PON will be deployed and deployed in 2019. Talking about the specific requirements of China Unicom's 10G PON deployment, Jia Wu said that China Unicom launched the mining test for 10G PON OLT in April 2018. For the 10G EPON symmetry requirements, the board should be able to support both symmetric and asy...

Frequently Asked Questions 1. What can I do if I cannot access the Internet? Answer: 1) Please confirm that the hardware connection is correct, whether the corresponding WAN and LAN lights are on, and whether the WAN and LAN lights are blinking (flashing indicates data transmission) to ensure the connection is valid. 2) In the bridge mode, whether the Internet can be accessed normally by dialing or other actual Internet access on the PC. If you can't get online: Please confirm that the PPP dialup software has been properly installed and completed. If can dial successfully, but still can't access the Internet, please confirm that the browser's proxy server settings are correct, and should be set to not use a proxy server;  Please try to log in to multiple websites to confirm that it is not caused by a website server failure;  Please try to disconnect the dial-up connection and dial again after 5 minutes. 3) If the Internet can be connected normally in the b...

GPON and EPON  have their own advantages. GPON is better than EPON in terms of performance indicators. However, EPON has the advantage of time and cost. GPON is catching up. Looking forward to the future broadband access market may not be a replacement, it should be complementary. For bandwidth, multi-service, high QoS and security requirements, and ATM technology as a backbone customer, GPON will be more suitable. For customers with low cost sensitivity, QoS and security requirements, EPON has become the dominant factor. What is PON? The PON (Passive Optical Network) is the main technology for implementing FTTH fiber-to-the-home. It provides point-to-multipoint fiber access. It consists of the OLT (optical line terminal) on the office side and the ONU (optical network unit) on the user side) and ODN (Optical Distribution Network). Generally, the downlink adopts the TDM broadcast mode and the uplink adopts the TDMA (Time Division Multiple Access) mode to form a point-to-multipoi...

The beauty of Wuzhen often only feels the most beautiful when you are there. However, what kind of scenery would you look at in Wuzhen through 5G network + 8K high-definition video? This is the upcoming 5G network. As the host of the World Internet Conference, Wuzhen has taken the lead in launching the construction of the 5G trial network. At present, more than ten 5G base stations have been set up, and the 5G trial network application innovation will be displayed during the Fifth World Internet Conference. 5G experience in the car 8K quality of Wuzhen HD live broadcast, is also one of the show projects. Since the end of 2016, Zhejiang Mobile has carried out G-scale trials many times since the 5G innovation exploration. Up to now, it has jointly carried out 360-degree VR live broadcast, remote B-mode, 5G AR remote maintenance, holographic call and other applications in the West Lake Scenic Spot. Innovation. At this Internet conference, there will also be some 5G network applic...

According to media surveys, an advertising marketing device with WiFi probes as the main technical means has quietly emerged. Such devices collect user information by acquiring the user's mobile phone Mac (Media Access Control) address. Some devices can force the user's mobile phone to pop up the window, and pretend to be connected to WiFi on the WeChat top interface to deliver "dog skin plaster" ads that cannot be eliminated. WeChat said that it has monitored such malicious deception and has responded technically to the monitored situation. The WiFi probe is suspected of infringing on the privacy of users and should be severely punished according to law. In addition to the network platform to assume responsibility, the regulatory authorities should also slash swords in time to protect personal information and build information security barriers.
