What you should know about the wifi bluetooth wireless network card

As you know, to achieve in desktop and laptop "wireless", while online desktop and laptop has a LAN card , 2-N Wireless Adapter network card can be composed of blocks of a multi-agency in the notice -- Special Exchange get wireless online gaming and sharing.

Currently on the campus of the university, the hotel cafeteria, individual user groups, etc. that exist in wireless hot spots (wireless access points, usually 1-n access point or wireless router), which allows the wireless adapter on your PC anytime, anywhere with easy access to the Internet. Therefore, in the new semester who want their own team, "the cable network and wireless network", taking into account student friend, the use of wireless LAN can be easy to get access to all wireless network card round has a large number of students started to become standard equipment on laptops friends.

Wireless Network Adapter Card Categories:

Currently on the market depending on usage and demand for wireless cards PCMCIA wireless network adapter, wireless PCI card, USB wireless network card, wireless mini PCI card, CF card and other types.Wireless PCMCIA Card only applies to laptops, hot plug PCI wireless cards for normal desktop use USB interface for wireless network card applies to both desktop and laptop machines, hot plug, Mini PCI only wireless laptops in particular, Mini-PCI for laptops, wireless networking cards CF card for Pocket PC (PDA).

The speed of the wireless network adapter card, you know, IEEE802.11b products maximum transfer rate of 11MB / s, when the radio conditions deteriorate, the data transfer rate can be reduced to 5.5Mb / s, 2 Mb / s and 1Mb / s, outside the permitted range is 300 meters in an office environment up to 100 meters. Although the transmission speed IEEE802.11b products in general, but has been unable to meet the requirements for access to broadband Internet, the most important is that these products are cheap, so price conscious friends of the Students may also be the first of these products in the wireless network to say. 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 the speed 54Mbps transmission.Students looking for friends or informal can optimize incorporate 802.11g 802.11g + (108 Mbps).

Bluetooth Wi-Fi Wireless PCI Card

PCI (Peripheral Component Interconnect) interface is a standard desktop interface on the motherboard, based on a 32-bit data bus operating frequency is 33 MHz, the second data transfer rate up to 132MB (32 * 33 MHz / 8), PCI interface, the transmission of the results has been able to play 802.11g + 108Mbps wireless card performance. The PCI, a PCI card WiFi Bluetooth is that most desktop users to upgrade to a wireless network a better choice.

Mini-Wireless Network Card Wi-Fi Bluetooth

And more miniaturized wireless MiniPCI MiniPCI Express card is similar to the portable computer memory card SO-DIMMs, compact and flexible. MiniPCI interface is a desktop based on the PCI interface for expansion of the standard interface laptop.TheMini Bluetooth WiFi card with integrated antenna itself is not based on preset in laptops in the body of the antenna to receive the signal, provided there is no slot on a laptop and an antenna MiniPCI preset or predetermined positions of the antennas can easily upgrade card wireless network card.

USB wireless network adapter

USB (Universal Serial Bus) interface is now the mainstream of computer interface, both desktops and laptops as standard. Wireless LAN hot-swappable, which makes the connection and data transmission is a wireless device may be established between multiple computers, is very comfortable to use. At the same time, with more than one desktop or notebook computer users to buy different USB interface elements provided theUSB wireless network adapter can be based on the use required to meet the needs of the majority of this team.

Wireless PCMCIA / PC Card Network

PC Card (PCMCIA) is a kind of notebook-use interface PCMCIA Type I, Type II, Type III are three different types of products, the length and width are 85.6 * 54 mm, but differ in thickness, which generally supports the former, however, not always as soon case.Not bit PC Card 16 -, PCMCIA cards are currently used in wireless LAN PCMCIA 32-bit, also known as CardBus. CardBus capable of 32-bit data and 33 MHz for the transmission of the operation, the compatibility of the PC Card 16-bit PC cards can be bus-independent, regardless of the main CPU, and direct data exchange between the computer's memory to the CPU can handle other tasks.Wireless CardBus card to close the maximum flow rate of 90Mbps, has been able to basically meet the demand for 108Mbps wireless card.Because there is no built-in network card or wireless network card for laptop users, the interface card for PCMCIA wireless network easily upgrade to a wireless network a good choice.

In the last hope? What I have said that may be of some help to you.
