Among them, the most concerned is undoubtedly that the CSRC has revised the Interim Measures for the Administration of Initial Public Offerings and Listing on the Growth Enterprise Market, appropriately reducing the initial financial access targets of the GEM, eliminating the requirement for continuous growth, and simplifying the conditions for issuance. At the same time, the GEM refinancing system has finally unveiled its mystery and set up a “small, fast and flexible†private placement mechanism.
Now, the high “threshold†that has hindered the listing of emerging industries such as LEDs is falling, and emerging industry companies are expected to usher in a new wave of listings on the GEM.
At the regular press conference on March 21, the GEM reform measures explicitly mentioned included appropriate reduction of the initial financial access indicators of the GEM, establishment of a refinancing system in line with the characteristics of the GEM and improvement of the GEM M&A system. Simplify the review process, etc. In these respects, the SFC was once considered to be "the threshold for listing is too high, forcing many companies to take advantage of fraud."
Some people in the investment community said that the GEM is targeted at innovative and growing SMEs. These companies are affected by various factors, and fluctuations in performance are inevitable. Previously, the GEM required continuous profitability did not meet the requirements. The characteristics of creation.
According to reports, the CSRC revised the Interim Measures for the Administration of Initial Public Offerings and Listing on the Growth Enterprise Market, and formulated the Interim Measures for the Administration of Securities Issuance by GEM Listed Companies (Draft for Comment) and stopped implementing the Good guidelines for recommending jobs on the GEM.
The new method for comment draft shows that the original regulation "continued profit in the last two years, the net profit in the last two years has accumulated not less than 10 million yuan, and continues to grow; or the profit in the most recent year, and the net profit is not less than 5 million yuan, recently The annual operating income is not less than 50 million yuan, and the growth rate of operating income in the last two years is not less than 30%", revised to "continuous profit in the last two years, the net profit in the last two years has accumulated not less than 10 million yuan; or recently One year's profit, the business income in the most recent year is not less than 50 million yuan."
This means that the income is above a certain scale, and only one year of profitable enterprises can be listed on the GEM, and the reporting enterprises are no longer limited to the nine major industries.
The implementation of the new measures will pave the way for a large number of LED companies that are affected by the economic environment and market fluctuations and cannot achieve profit for two consecutive years.
Since 2012, due to the crazy investment in the LED industry in the past few years, the industry has a serious overcapacity, coupled with the sluggish demand in the downstream application sector, the export has been greatly reduced due to the impact of the overseas financial crisis, and the industry has entered the winter. Many of the LED companies that are going to be listed have experienced a sharp decline in their 2012 annual results, which is unable to meet the requirements for continuous growth in the performance required for listing.
According to the statistics of the website of the China Securities Regulatory Commission, among the companies with LED-related business as their main business, the enterprises that have terminated the initial public offering of shares in 2013 are Dalian Luming Lighting Technology Co., Ltd., Yunnan Lanjing Technology Co., Ltd., Beijing. Jinlixiang Art Color Technology Co., Ltd., Shengdi Optoelectronics Technology Co., Ltd., Shenzhen Cuitao Automation Equipment Co., Ltd. and other six LED companies.
Some of these companies were forced to terminate the listing process because they did not meet the criteria for continuous profitability.
"The new regulations are undoubtedly a big benefit for companies that want to go public, especially those that have good growth but whose performance is highly volatile due to macroeconomic and industrial development." Researchers with brokerages believe that they have already launched listings because of poor performance. The company is likely to "return".
These companies that have experience in IPO filing and have terminated IPOs due to “slow performance†are also considered by brokerage institutions to be the most likely to rekindle the ambitions of GEM due to the New Deal.
"High-tech LED" reporter learned that those LED companies that have withdrawn IPOs have not given up, and there is still a willingness to list. The GEM is the most considered option. After the New Deal came out, LED companies have already consulted with brokers about the situation.
Z Company is an LED company that actively suspends IPOs during the 2013 financial verification storm. According to people familiar with the situation, the brokerage company responsible for sponsoring at that time believed that the performance of the company was highly volatile, and it was difficult to pass the customs and demanded that the company withdraw the order.
According to industry insiders, in 2012, the entire LED industry was in a cold winter, and the downstream demand was not prosperous. In addition, over-investment in the previous years led to overcapacity, and the industry as a whole was in a state of low profit or loss, and the company was not spared.
Insiders of the company revealed that the company has not given up the idea of ​​listing, and the company has already studied the relevant content for the first time after the introduction of the new initial draft for the GEM. In 2013, the company's performance was good. After the annual report came out, it should continue to declare the IPO.
Some LED industry veterans said that the Pearl River Delta and the Yangtze River Delta have a large number of LED companies with more than 50 million revenues. Many of them have technology and market. If they can get help from the capital market, they will undoubtedly stand out. 
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.
Listed Threshold Reduces LED Welcomes a Wave of GEM Listing
[Text/Zhao Hui] On March 21, Zhang Xiaojun, spokesman of the China Securities Regulatory Commission, said at a regular press conference that in order to implement the spirit of the "Three-Plenary Capital Market System of the Eighteenth Central Committee of the 18th CPC Central Committee" and the State Council With regard to supporting the development of SMEs and financial support for economic transformation and upgrading, and better promoting the support of the capital market to adjust the structure and transfer methods, the CSRC has taken various measures to promote the reform of the GEM market and promote the GEM market to become an innovation. A capital market platform for the development of small and medium-sized enterprises.
