Current Status of Lighting Industry in Shiyan City, Hubei Province (Photos)
Located in the northwestern part of Hubei Province, Shiyan City is the junction of the adjacent areas of Hubei, Henan and Shaanxi provinces. It is about 500 kilometers away from Wuhan, Zhengzhou, Xi'an and Chongqing. Since ancient times, there have been “South Ship North Horse, Chuanshan Throat, Four The province is known as "the most important thing." The city covers an area of ​​24,000 square kilometers and has a total population of 3.5 million. The Shiyan was built by the car and was driven by the car. It is the hometown of the famous "East Windmill" at home and abroad. It is a famous "automobile city" in the country and a commercial vehicle production base of "China's first and the world's top three." What is the current status of the lighting and lighting industry in such an important city? The reporter recently had in-depth exchanges with many merchants in the various lighting markets in Shiyan City.
Jing Xuhua Market is a unique show
There are more than 100 lighting, electrician and electric materials merchants in Shiyan City. They are mainly distributed in Renmin North Road and Jingxuhua Lighting Materials City, such as Macau Street Lighting City, Haobai Year Lighting City and Chenye Building Materials Market.
The Chenye Building Materials Market is located near the Shiyan Railway Station and was opened in 2000. There are currently 20 lighting merchants in the market. These merchants mainly face small-scale wholesales in subordinate counties and townships. The products they represent are also small brands. It is mainly based on miscellaneous cards. Although the business conditions are still ok, there is no influence in Shiyan City.
Hundred Years Lighting City is located in the building materials market of the century. It also has more than 20 lighting merchants. However, due to the decline in popularity, there are only a dozen or so dealers in the market. The market will be able to go in the future. How far away, local industry insiders generally hold a negative attitude.
There are more than 20 lighting merchants in Macau Street Lighting City. The current operating status is generally due to the fact that Macau Street is also a comprehensive building materials market. The market is currently focusing on ceramics, which has caused the shrinking of lighting dealers. Even the lighting merchants directly transferred from Macau Street to the nearby Jingxuhua.
Jingxuhua Lighting Materials Market was established in 2002. It is currently the most concentrated lighting distributor in Shiyan City. The most popular lamps are sold. There are currently more than 40 dealers in the market. Some famous lightings and lightings at home and abroad. Electrician brands can be seen in this market. The reason why Jingxuhua's lighting and electric materials market can be dominant in Shiyan City is mainly due to three reasons, one is because there are more big brands in the market, and the other is because the market is located in Shiyan City. The business district is very advantageous in terms of geographical location; on the other hand, because the surrounding environment of the market is very good, the nearby Renmin Road and Renmin North Road are all merchants that operate hardware decoration and electrical materials, including NVC. Many well-known brands such as Sanxiong, Aurora, Op, Jiamei, Langeng, Benbang, Huayi, etc. can be seen on this street. China's outstanding lighting distributors - Hubei Shiyan Dafeng Industry and Trade Co., Ltd. more than 1,000 square meters of hypermarkets are also located in the People's Road.
Since then, Jingxuhua's lighting and electric materials market and the lighting and industrial and commercial households on the People's Road have echoed each other, forming the most popular lighting and lighting business circle in Shiyan City, becoming a unique show in the local industry.
Well-known brands in Shiyan
Foton Electric

First, Wireless Router
So what is a wireless router?
Wireless router, according to the definition of Baidu Encyclopedia: Wireless router is used for users to access the Internet, with wireless coverage of the router.
A wireless router can be thought of as a repeater that forwards the broadband network signal from the wall of your home through an antenna to nearby wireless network devices (laptops, Wifi-enabled phones, tablets, and all Wifi-enabled devices).
The popular wireless routers in the market generally support four access methods: dedicated xdsl/cable, dynamic xdsl, pptp, and generally can only support 15 to 20 devices online at the same time. It also has some other network management functions, such as dhcp service, nat firewall, mac address filtering, dynamic domain name and so on. The signal range of the general wireless router is 50 meters radius, and the signal range of some wireless routers has reached 300 meters radius.
The name of wireless router can be separated out of two keywords: wireless and routing.
Understand the technical principle behind these two words, you understand the wireless router.
Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function. In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
Second, the demand for wireless routers
I do not know if there is a sudden WIFI break when you play games at home, and a stable router is crucial at this time. However, it is important to note that your WIFI frequently dropped may not be a problem with the router, it may also be a problem with the carrier network. (Router means I don't back this pot)
In fact, for most people, there are two basic requirements for wireless routers
Stable and do not drop
Fast Internet and easy setup
Some people will have some advanced needs:
There are some features, USB interface, can be external U disk or hard disk, can achieve simple nas functions, QOS, etc., to advertising and so on
Mesh networking, when the house area is large, multiple routers can be used for Mesh networking
How to choose a wireless router
The wireless router market is in the transition stage from WiFi 5 to WiFi 6, if you want to buy the first choice is definitely WiFi 6 wireless router, which is the future trend.
The speed of WiFi 6 is nearly 40% higher than the previous generation 802.11ac, and the highest connection speed can even reach 9.6Gbps, while the highest speed of 802.11ac is only 6.93Gbp. More importantly, unlike 802.11ac, which only covers the 5GHz band, WiFi 6 covers 2.4GHz and 5GHz. Although the 5GHz band has less interference, it has weak wall penetration ability, and the 2.4GHz band has strong wall penetration ability, which takes into account each other.
So why choose a WIFI6 router?
Compared with the previous generation of 802.11ac WiFi 5, the maximum transmission rate of WiFi 6 in the 5Ghz band has been increased from 3.5Gbps to 9.6Gbps, and the theoretical speed has been increased by nearly 3 times. WiFi 6's 5Ghz single-stream 80Mhz bandwidth can reach theoretical speeds of up to 1201Mbps and 160Mhz bandwidth of up to 2402Mbps.
The band supports 2.4Ghz and 5Ghz.
In terms of modulation mode, WiFi6 supports 1024-QAM, which is higher than the 256-QAM of WiFi 5, and the data capacity is higher. Some high-end WiFi 6 routers support 4096-QAM.
WiFi6 supports MU-MIMO (multi-user multiple-input multiple-output) technology, and supports both upstream and downstream MU-MIMO, with a maximum support of 8T×8R MU-MIMO. The speed is greatly improved. High concurrency, WiFi6 5GHz band, terminal connections up to 128! 5 times that of WiFi5. Effectively solve the Internet needs of multi-person networking and smart home;
WiFi6 adopts OFDMA (orthogonal frequency division multiple access) technology. After using OFDM to parent the channel, the transmission technology of transmitting data is loaded on the subcarrier, allowing different users to share the same channel, allowing more devices to access, with shorter response time and lower delay.
Low latency, WiFi6 time delay can be as low as 10ms, compared to WiFi5 30ms delay, only 1/3. This performance refresh is extremely friendly to game lovers;
If WiFi6 (wireless router) devices need to be certified by the WiFi Alliance, they must use the WPA 3 security protocol, which is more secure.
The WiFi6 wireless router is backward compatible with WiFi5 and WiFi4 terminals.
Fourth, the misunderstanding of purchasing routers
Is the through-wall router really through-wall?
Mistake; The country has strict limits on the transmission power of the wireless router antenna, if you have a lot of rooms in your home, and there are many walls between them, even if you buy an expensive wireless router, you can not do one to cover all the room signals. If the signal is not good, you can consider multiple wireless router Mesh networking.
Does a wireless router have a stronger signal with more antennas?
More antennas just to match the X*X MIMO mode, the more antennas, the more channels, can only ensure that the network is more stable, the impact on the signal is little, the strength of the signal is only related to the wireless transmission power. The wireless transmission power of the country has a standard.
