Want wireless Internet companion, many have their own notebook Chrono negligence may desktop excuse type, and the blind selling the wrong wireless network connection to the Internet. So next to the masses and detailed overview of wireless network card interface type. Help people choose the correct network card.

Wireless Internet card interface which

Now, the primary use of wireless network card in your notebook and PDA (handheld computer), there are local use on the desktop, so that its interface also has many kinds of specifications. Many of the primary with PCMCIA interface interface, USB interface, ExpRESS34 interface, interface, CF interface EXPRESS54, etc.

Wireless Internet card interface: PCMCIA interface

This variety of interfaces in General is a wireless network card, move with their own notebook, it is a laptop space limit, the volume is far not enough like PCI interface card. PCMCIA bus is divided into two categories, one category is the 16-bit PCMCIA, another class is a 32-bit CardBus.

CardBus is a notebook computer's new high-function PC card bus interface specification, as generally used in the desktop computer's PCI bus. This bus specification and the original PC card specification, have the following advantages: first, the 32-bit data transfer and 33MHz operation. High-speed Ethernet CardBus PC card for maximum throughput, while close to 90Mbps 16-bit high speed Ethernet PC card can only be reached 20-30Mbps. Second, the bus independently. The PC card can separate from the main CPU, and direct communication between the computer's memory, CPU can handle other duties. Third, power supply, low power 3.3V. Improves battery life, lowered heat dispersion inside the computer, to enhance the reliability of the system. Fourth, backward compatibility for 16-bit PC cards. Old Ethernet and Modem equipped with PC card can still be in use on the CardBus slot.

Wireless Internet card interface: USB interface

USB (UniversalSerialBus, universal serial bus interface) due to the transfer rate is far better than the traditional parallel port and serial port, equipped with devices easily and supports hot-plug. USB equipped once access, you can immediately be computer confession, and mount any need to drive order, and do not have to restart the system you can put to use immediately. When you no longer need to be equipped with a desk, ready to unplug it, and then in the port of inserting another new outfit, then this new equipment will also be immediately recognized and immediately start a task, so more and more by manufacturers and users like.

Wireless Internet card interface: CF interface

CF (CompactFlash)-the primary use of wireless network card in PDAs equipped with internal, CF card in accordance with the ATA specs, but its interface is a 50-pin instead of a 68-pin, bonus two rows, each row of 25 pins. CF card is divided into two categories: TypeI and TypeII, specifications and characteristics essentially similar. Between the two models, the only difference is the thickness of the card. CF card is not a hard drive that kind of needle type interface and a 50-pin (1.27mm), pass the interface is not easy to be damaged, this design and PCMCIA interface is similar.
SD interface or Expresscard interface
As for the SD interface or Expresscard interface products, we recommend people temporarily without thought. SD interface requirements are equipped with wireless network card with SDIO interface, just a few PDA support, and price.

As for the Expresscard interface, although it replaces the old PCMCIA interface tends to be undisputed, but at least now also seem too advanced.
