How to choose the right wireless network card according to the type

The advent of the wireless network era allows people to get rid of the shackles of cable, anywhere can access a variety of networks, to people's work, life and entertainment brought convenience. Wireless network can not do without wireless card, how to choose the wireless card? The choice of wireless network card and ordinary cable network card purchase some different, we recommend that you consider the following aspects to buy the appropriate wireless network card.

Type of wireless card (interface selection)

Now the main interface of wireless network card is PCMCIA, PCI, USB and CF four kinds. The PCMCIA standard is used for the notebook peripheral interface More, the product volume is smaller, the weight is lighter, the use is more convenient, the performance is better, is the current notebook computer's first choice; PCI specially designed for highly integrated peripheral components, expansion boards, processors, memory systems, the interconnection machine, once launched into the current high-performance microcomputer generally supported by the bus; USB technology solves the current connection complexity of serial devices and parallel devices, greatly simplifies the connection process between computer and peripherals, simple installation support Plug and Play, hot plug, multiple equipment parallel, can provide greater bandwidth, bright prospects; CF card internal use of analog hard disk controller design, you can easily through the IDE interface to connect with the computer, to a certain extent, can play the role of mobile storage. You must pay attention to the interface type when you purchase the wireless network card, otherwise it cannot be used.

Select a wireless network card based on the terminal type

The most basic principle is to choose the wireless network card according to the terminal type, at present, our common network terminals mainly have desktop computers, laptops and PDAs and other handheld devices. Here we will say different terminals how to choose different wireless network card.

1, desktop computer: PCI, USB wireless network card

Desktop computer because does not need to move, therefore, the network card appearance, the size, the weight and so on request is not high, therefore may choose the PCI interface wireless network card, compared to other types, this kind of network card price is also lowest. However, the installation is relatively complex, you need to open the chassis for installation, some products will be outside the chassis exposed antenna, some products are built in. From the effect alone or external antenna products better. In addition, the desktop computer can also choose the USB interface of the wireless network card, it really as a peripheral to use, but the price of the USB card will be higher, but through the Plug and Play USB function, can facilitate installation. Consumers can choose the type of wireless adapter for desktop computer according to their own specific situation.

2, notebook computer: PCMCIA, USB wireless network card

Notebook computer also called portable computer, as the name suggests mobility is its biggest characteristic, therefore, the notebook computer to the wireless card request is the highest, regardless of appearance, or from its compatibility must be strict requirements. And the wireless card itself relies on laptops to survive, because most users choose a wireless network card because its terminal is a notebook computer. PCMCIA Wireless network card disassembly is convenient, and will not increase too much weight, is the current notebook computer ideal collocation. Since laptops are very mobile and may interconnect across multiple areas, compatibility becomes the ultimate factor. USB wireless network card, as a laptop wireless network card is a complementary product also plays an important role.

3, PDA:CF wireless network card

The development of PDA is very rapid, in some fields, can even replace the notebook computer, and as people's demand for information on the explosion, the PDA must be able to achieve interconnection, so the CF wireless network card was born, because most of the PDA with CF memory card interface, CF wireless network card can be quickly popularized. Through the CF wireless network card, the PDA product has the broader space to play.
