What you should know about the bluetooth wifi wireless network card
As you know, to achieve desktop and notebook computers "wireless", as long as desktop and notebook computers have a wireless card on-line ,2-n wireless network adapter card can be composed of blocks of a multi-agency into the Ad-Hoc Wireless peer networks to achieve Networking playing games and sharing online.
Currently at the university campus, the hotel coffee shop, individual user groups, etc. that exist in wireless hot spots (wireless access points, generally 1-n wireless AP or wireless routers), which allows you to have the PC with wireless adapter anytime, anywhere easy access to Internet. Therefore, in the new semester want their own computer "cable network + wireless network" taking into account student friend, use the wireless LAN network can be easy to achieve all-round access, wireless network card has a lot of students started to become standard equipment on laptops friends .
Wireless Network Adapter Card Categories:
Currently on the market based on usage and demand for wireless cards into PCMCIA wireless network adapter, PCI wireless network card, USB wireless network card, Mini PCI wireless card, CF card and other types . PCMCIA wireless card which only applies to laptop computers, hot-swappable; PCI wireless cards for ordinary desktop use; USB interface to the wireless network card applies to both notebooks and desktop machines, hot-swappable; Mini PCI wireless card only in notebook computers, Mini PCI special interface for notebook PCs; CF card wireless network card for Pocket PC (PDA).
The speed of the wireless network adapter card, you know, IEEE802.11b products maximum data transfer rate of 11Mb / s, when the radio conditions deteriorate, the data transfer rate can be reduced to 5.5Mb / s, 2Mb / s and 1Mb / s, Supported range is in the outdoor 300 meters, in the office environment for up to 100 meters. Although the transmission speed IEEE802.11b products in general, but has been able to meet the requirements of broadband Internet access, the most important is that these products are cheap, so price-conscious student friends can also be the first of such products into the wireless network to say. It can be seen as IEEE802.11b and IEEE802.11g high-speed version, in order to achieve 54Mb / s transmission speed, 802.11g and 11b of different uses OFDM (Orthogonal Frequency Division Multiplexing) modulation method, which supports 54Mbps transmission rate. Students in the pursuit of the mainstream friends can optimize 802.11g or informal 802.11g + (108Mbps) products.
Bluetooth WiFi Wireless PCI Card
PCI (peripheral component interconnect) interface is a desktop standard interface on the motherboard, based on a 32-bit data bus operating frequency is 33MHz, per second data transfer rate of up to 132MB (32 * 33MHz / 8), PCI interface, the transmission of Performance has been able to play 802.11g + 108Mbps wireless card performance. PCI interface, a bluetooth wifi wireless pci card is that most desktop computer users to upgrade to a wireless network a better choice.

Wireless Mini Network Card WiFi Bluetooth
MiniPCI and more miniaturized MiniPCI Express wireless card is similar to notebook computers SO-DIMM memory card, compact and flexible. MiniPCI interface is a desktop based on the PCI interface for expansion out of the interface standard notebook. The wireless mini card wifi bluetooth itself does not integrated antenna, relying on preset in notebook computers in the antenna body to obtain the signal, so long as there is on a laptop MiniPCI slots and preset antenna or preset positions of the antennas will be able to easily upgrade card for wireless network card.

Wireless USB network Adapter
USB (Universal Serial Bus) interface is currently the mainstream of the computer interface, both in desktop and notebook computers it as standard. USB Wireless LAN hot-swappable, making the connection and data transmission is like a mobile device, you can pull between multiple computers to pulling out, is very convenient to use. For the same time, with more than one desktop or notebook computer users to purchase several pieces of USB interface, as long as the wireless usb network adapter can be based on usage required to meet the needs of more than this computer.

Wireless PCMCIA/PC Network Card
PC Card (PCMCIA) is a kind of notebook-use interface, PCMCIA with Type I, Type II, Type III are three different types of products, its length and width are 85.6 * 54mm, but differ in thickness, which generally compatible with the former, the contrary is not always the case.Not like early 16-bit PC card is, the current wireless PCMCIA LAN cards are used in 32-bit PCMCIA, also known as CardBus. CardBus capable of 32-bit data transmission and 33MHz operation, its backward-compatible 16-bit PC cards, PC cards can be bus-independent so that independent of the main CPU, and the direct exchange of data between the computer's memory, so that CPU can handle other tasks . CardBus wireless card close to the maximum throughput of 90Mbps, has been able to basically meet the demand for 108Mbps wireless card. For there is no built-in network card or wireless network card for notebook computer users, PCMCIA interface, the wireless network card is that they easily upgrade to a wireless network a good choice.
At last?hope that what I've said could be of some help to you.
