There are two ways of computer wireless Internet access. One is to use the wireless network card that comes with the notebook to access the Internet through wireless routers. The other is to use the mobile phone card wirelessly.
The "wireless network card" Internet access to the laptop:
It is another network card in addition to a fixed local network card with a fixed RJ45 interface. line. The wireless network cards currently sold on the market generally meet the wireless LAN communication standards formulated by 802.11a, 802.11b, 802.11g, and 802.11n formulated by IEEE of and ENGINEERS of the market. The more communication standards that can meet a wireless network card, the wider the adaptive surface in actual use.
With this wireless network card, the laptop can be added to some wireless networks that meet the above LAN communication standards. For example, you can connect laptop electricity and public places such as some airports, railway stations, restaurants (KFC, etc.), hotels such as wireless network landing to their wireless routers. If their routers can be connected to the Internet and there is no password (this is nonsense, otherwise what kind of service is provided?), Then you can get online.
It with this wireless network card, it is good at your home or unit. If you add a wireless router, then you don’t need to log in to LAN (LAN) or Internet Wiring. As long as you have this wireless router signal, you can access the Internet (like a mobile phone), instead of being placed on a fixed table like a fixed local network card computer. The specific location depends on the length of the network cable. Essence
Note:
1) If you use it yourself, the wireless router you need for this wireless network card still have to buy it yourself (the home use generally does not exceed 200 yuan).
2) The wireless signal issued by the wireless router is transmitted by straight lines. There is a distance limit. The farther the distance, the weaker the signal until it is completely without signal. And wireless signals cannot cross the earth (the earth itself is a good conductor), metal and other substances. Therefore, the wireless signal cannot pass the floor and pillars built (structured) with steel bars inside. And the more the walls, the thicker the wall, the worse the wireless signal received by the laptop. The larger the transmitting power of the wireless router, the stronger the signal, the smaller the influence of the above situation. At the same time, the larger the electromagnetic radiation itself, the more unfavorable it is to the health of the human body.
3) For cost considerations, low -end laptop computers (such as products below 3800 yuan) generally do not bring this wireless network card. To achieve this function, consumers need to buy separately by themselves.
4) Similar to desktop computers, but you need to install a wireless local network card, which is just one antenna behind the ordinary cable network card.
In the wireless Internet method of mobile phone card:
This it is generally made into a PCMCIA card (85.6mm × width 54mm × thickness 5.5mm, because the abbreviation is too long, so some people call it called it called it The form of "PC Card"): first provides services for mobile phone chip cards (in mainland China, two such mobile network service providers, one is: "China Unicom (" China Telecom in the near future) " UPN card, use CDMA network online; the other is the "China Mobile" SIM card, use GPRS network to access the Internet) inserts into the PCMCIA card, and then insert this PCMCIA card into the PCMCIA card slot of the laptop (if there is no PCMCIA on the laptop computer, there is The card slot, you can buy similar devices of the USB interface, but it is inconvenient to carry). After installing the corresponding driver and opening the network service, you can use the mobile phone honeycomb network dial -up to access the Internet.
The wireless Internet method that uses mobile phone cards does not need to buy wireless routers by yourself (the cellular network base station of mobile phone is equivalent to a large wireless router), as long as there is a mobile phone signal (wireless base station station (wireless base station station AP coverage) can go online.
The wireless Internet card that uses the wireless Internet card of the wireless mobile phone honeycomb network is much slower than the wired local network card (up to 150kbps, and the current bandwidth of home wired broadband Internet access is generally 512kbps, 1Mbps, and 2Mbps、4Mbps等。但它还是比传统的利用模拟信号电话线路的拨号上网方式的54Kbps快了一倍以上），但是地球上不是每个地方都有宽带或无线路由器接口供你用的，也不是Each place is connected to a wired phone. For example, when you take a car, train, airplane, and ship transportation, or when you simply are outdoors, you may not even have electricity. At this time, the wireless Internet card will play its role. The Internet (Lian Mount Everest was covered by the mobile phone base station signal).
Note:
1) Due to the different price levels of each region, specific tariff issues need to consult the ISP dealer where the location is located, that is, "China Unicom (" China Telecom in China ") or" China Mobile".
2) In the same way of desktop computers, the wireless network card of the USB interface is inserted to the USB interface, but the desktop computers generally do not need to move as the laptop, so no one does so.
1. Access to the service provider's price
After the price war of ISP operators last year, the adjustment of the new round of telecommunications tariffs has caused a new turning point in the development of China's Internet. Telecom tariffs dropped to 1.2 yuan/hour Internet access fee to make the access market more popular. Telecom rental tolls were reduced from 4,500 yuan/month to 2,000 yuan/month. Operators are private, and they will face fierce market competition. The ISP business billing method operated by the telecommunications department is basically implemented in accordance with the Chinese telecommunications price system. Most of them are paid by Internet fees and telephone fees. There are many renewal outlets, and online payment is generally adopted.
2.isp operator service content
private ISP faces fierce market competition and potential threats from broadband. Simple access services are not enough to support the normal of the enterprise's normal Operations; traditional access service providers are looking for new fulcrum in the war. From accessing to website construction and website maintenance, providing the entire set of services has become a trend of the development of ISP operators. A large number of solutions have been launched: ISP's key service items include access platform services (virtual hosting, domain name registration, website design, etc.), IDC (server hosting and rent), ASP (application service provider), AIP (application basic service service) Provider), etc., the current access service is still the largest source of income for ISP operators.
The ISP in China, especially the ISP of non -telecommunications companies, has changed a lot in business content. In addition, due to the small space for personal access to business, the market share of dial -up and special line access users is basically occupied by more than 80%of telecommunications companies. The remaining 20%of the market share is not enough to support 150 domestic operations and more than 500 provincial and municipal ISPs. ISP shifted from simple access services to the application service of the enterprise. For example, IDC operators invested a large amount of capital construction machine rooms and other hardware environments in 2000 to welcome the arrival of large -scale Internet access and wider e -commerce application stage.
It, we can see the following characteristics:
1. From the Internet personal user cultivation stage of personal access to personal access to the enterprise -oriented application service stage. This is At present a fundamental change in ISP in my country.
2. From simple access service to provide a package of services. In the past few years, the content of the ISP service is relatively simple, that is, the dial -up and dedicated line access, supplemented by virtual hosting, host custody and domain name registration. With the evolution of the Internet development stage, this simple service can no longer be able to no longer be possible Meet the needs of personal and enterprise users on the Internet. What the user needs is to be comprehensive and forward -looking services from access to comprehensive. ISP operators shoulders new tasks to guide corporate information construction. This transformation has made ISP operators no longer simply use media advertising and promotional activities to expand users. Instead, it is necessary to rely on technological advantages and service features to create demand.
3. The service content is series, which has continuous characteristics. One feature can be found in our current ISP service project, that is, all the needs that companies can put forward, ISP can basically meet. The role of ISP operators has a variety of roles such as system integrators, software developers, and e -commerce platforms.
Now it is GPRS (mobile) and CDMA (Unicom) recommended CDMA speed faster than the former depending on the Internet card brand 400 ~ 800, aspirations and cities in various provinces and cities. Just appropriate. In addition, use wireless Internet card to access the Internet. You can only talk about a webpage .. Game online movies and so on ... You must consider it before buying
