Your Guide to PCI WiFi Cards

Peripheral Component Interconnect (PCI) is a computer industry standard for connecting devices to the central processing unit. A PCI WiFi card connects authorised users to wireless computing networks. Consumers in the market for a PCI card must consider bandwidth, specifications, and security features to find the right card for their needs.


About PCI WiFi Cards

PCI wireless cards are one of several cards that utilise the PCI connection standard. The connection standard supports graphics, audio, and network hardware for interaction with the motherboard, CPU, and memory. PCI WiFi card power depends on the potential bandwidth of the connection, the designated bits per connection, and MHz processing speeds.


Bits Per Connection

Processing Speed (MHz)

Potential Bandwidth (MBPS)











The three types of expansion slots and cards are compatible with each other. However, PCI WiFi card users typically must default to the lower setting for a card and slot that operates on a wider bus and faster bus speed.


Random Access Memory

PCI WiFi cards operate with random access memory (RAM) capacities that manufacturers determine during the production process. RAM allows the processing of complex, multi-layered file data by storing integral components of the data in temporary memory. The amount of RAM indicated on the label of a PCI WiFi card corresponds to its performance level. Users who operate PCI WiFi cards that contain a large amount of RAM can handle more data during internet downloads or while saving files on a wireless network.


PCI WiFi Card Specifications

Wireless 802.11 is a group of specifications developed for wireless local area networks (LAN). The 802.11 specification establishes interaction between a wireless client and base station, as well as between two wireless clients. The transmissions travel over the frequency hopping spread spectrum or direct sequence spread spectrum. PCI WiFi cards vary in range and consumers must calculate how far away they operate from the wireless network to determine the range they need. Cards that exceed 200 millimetres and include an antenna that sticks out from the back of the computer typically have the greatest ranges. Consumers should have no problem fitting PCI WiFi cards into a PCI expansion slot, but they should still compare dimensions of the slot and WiFi card before making a purchase. Moreover, PCI WiFi card users must ensure the cards are compatible with motherboard slots.


Security Features

Only authorised users should be able to access designated wireless networks. The top PCI WiFi cards possess security features that ensure uninterrupted performance. PCI WiFi cards must have the capability to protect users from invasive malware and other harmful software. Password protection should include difficult to decipher parameters that include symbols, upper case letters, and numbers. Only the wireless network administrator should have access to the security features.
