Failure to Complete the Phase-out Tasks Strictly Controlled Investment Projects Jiangxi Province has formulated the “Twelfth Five-Year Plan†for key industries to eliminate backward production capacity implementation plans and implemented the task decomposition to various regions and years. Improve the backward production capacity withdrawal mechanism, guide and supervise the elimination of backward production capacity enterprises to do a good job of staff placement. We will improve the elimination of production capacity announcement system, strictly control financially supported investment projects in places where deadlines are not fulfilled, and suspend the approval, approval, and filing of construction projects for key local industries; and revoke enterprises that have not completed deadline elimination tasks in accordance with the law. Emission permits, production licenses, and safety production licenses.
The rapid growth of energy consumption will be adjusted according to national arrangements for early-warning and control. Jiangxi Province establishes a mechanism for the decomposition and implementation of total energy consumption control targets in line with the province's actual implementation, and implements the total-level control targets to be implemented at all levels of the people's government and relevant departments to implement target responsibility management. , increase assessment and supervision. Establish a forecasting and early warning mechanism for total energy consumption, and provide early warning and control of places where total energy consumption has grown too fast.
Incomplete annual energy-saving enterprise mandatory energy audit Jiangxi Province implements an energy audit system, establishes and improves the enterprise energy management system, implements the energy utilization status reporting system, and promotes the implementation of energy-saving transformation. The implementation of key energy-consuming enterprise cadre hanging points to contact the energy-saving work system, arrangements for provincial direct and sub-district level city and above leading cadres to contact one company. We will assess the completion of energy-saving targets for key energy-using industrial enterprises, and impose mandatory energy audits on companies that have not completed annual energy-saving tasks, and rectify them within a time limit.
Eliminated the registration of "Yellow Label Car" before 2005
Jiangxi Province will also rationally allocate various transport resources in cities, give priority to the development of urban public transport, and promote the construction of urban rail transit in an orderly manner. Increase the proportion of railway electrification. Deeply carry out special campaigns on low-carbon transportation and transport for 1,000 companies in “caravans and ports†to promote energy conservation and emissions reduction in aviation and ocean shipping. Accelerate the elimination of old cars, locomotives, and ships, and basically eliminate the "yellow-marked cars" that were registered before 2005. Accelerate the improvement of vehicle fuel quality and implement the fourth phase of motor vehicle emission standards. Full implementation of motor vehicle environmental protection sign management.
In the “Twelfth Five-Year Plan†period during the “12th Five-Year Plan†period, the province will deepen the price reform of resource products and rationalize the relationship between resource prices for coal, electricity, oil, gas, water, and mineral resources. Promote the use of electricity and water ladder prices for residents. Improve power peak-to-valley time-sharing electricity price implementation methods. The punitive electricity price shall be applied to enterprises and products whose energy consumption exceeds national and local standards for energy consumption (power consumption) per unit product. Within the scope permitted by the national policy, the implementation of the differential electricity price and the punitive electricity price will be expanded as needed. Further improve the sewage treatment fee policy and study the sludge treatment costs gradually incorporated into the sewage treatment costs. Reform waste disposal fees and reduce collection costs.
Selection of prevention and control tasks Heavy taxation and taxation on environmental taxes Jiangxi Province has fully implemented the reform of resource taxes and charges. The measures for calculating the resource tax for crude oil, natural gas and coal have been changed from specific collection to ad valorem collection and the level of taxation has been appropriately raised. Unfair toll fund projects. Actively promote the reform of environmental taxes and fees, select prevention and treatment of heavy duty, technical standards, the maturity of the taxation of the introduction of environmental protection tax, and gradually expand the scope of collection.
Corporate Environmental Illegal Information and Credit Rating Linkage Jiangxi Province has proposed to increase credit support for energy-saving emission reduction projects by various financial institutions and encourage financial institutions to innovate credit management models that are suitable for the characteristics of energy-saving emission reduction projects. Raise the threshold for the “two-high†industry loans, incorporate corporate environmental law information into the People's Bank Enterprise Credit Information System and the Banking Regulatory Commission Information Disclosure System, and link with corporate credit rating, loans and securities financing. Establish and implement a green bank rating system, linking the effectiveness of green credits with the performance assessments of bank executives, institutional access, and business development.
Unfinished emission reduction tasks Phased Environmental Impact Assessment (EIA) limit approval Jiangxi Province regards the total amount of pollutants discharged as the pre-condition for the environmental assessment, and places and enterprises that have not achieved the annual emission reduction targets and the key emission reduction projects are not implemented according to the target responsibility. The implementation of phased environmental assessment limit approved. For the investment projects that fail to pass the energy assessment and environmental review review, the relevant departments shall not approve, approve or approve the start of construction, and may not issue production licenses, work safety permits, or sewage discharge permits. Financial institutions may not issue loans, and the relevant units may not provide water or electricity. .
Contaminants exceeded the standards The “black list†was issued in due course to the strict management of Jiangxi's discharge permits. Strengthen the supervision of pollution sources in key river basins, key areas, and key industries, and issue timely lists of enterprises with major pollutants exceeding the standard. The construction of urban sewage treatment facilities is seriously lagging behind, the charging policy is not implemented, the actual treated water volume within 6 months after the completion of the sewage treatment plant is less than 60% of the design capacity, and the sewage treatment facilities have been built but there is no reason not to operate, the approval of the urban project shall be postponed. The EIA has suspended issuing national and provincial construction funds for the relevant projects.
Emission reduction targets shall be integrated into leading cadres' comprehensive evaluation and assessment requirements in Jiangxi Province. Relevant departments of people's governments at all levels must organize special inspections of energy saving and emission reduction, supervise the implementation of various measures, and severely investigate and punish violations of laws and regulations. The implementation of the responsibility system for energy conservation and emission reduction law enforcement, and the acts of administrative inaction, ineffective law enforcement, etc., strictly investigate the responsibility of the person in charge. In addition, the completion of energy saving and emission reduction targets and the implementation of measures are taken as an important part of the comprehensive evaluation and evaluation of leading groups and leading cadres, and they are incorporated into government performance and performance management of state-owned enterprises, implementing the accountability system and the “one-vote veto†system.
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.
