Wireless Card

  • Wireless card is generally regarded as the controller of network line up rather a more network card through which a radio-based computer network is united.
  • It is not similar to a standard network line up controller through which normal wire-based network such as Ethernet or symbol ring is linked up.
  • The Layer 1 and Layer 2 of the OSI Model are generally regarded as the working platform of wireless model.

Utilities of Wireless Card

  • For wireless desktop computer a wireless card is treated as the most necessary constituent.
  • The antenna of the card is utilized as the corresponding devices through microwaves.
  • In a desktop computer normally a wireless card is attached through the PCI bus.
  • There are various alternatives for wireless card connectivity such as USB and PC card.
  • Even incorporated wireless card is also obtainable in archetypal Mini PCI or PCI Express Mini Card format.

Attributes of Wireless Card

  • Ad hoc method and infrastructure form is usually the mode through a wire less card functions.
  • Each and every data information can be transmitted through an infrastructure mode network of the wire less card provided it should possesses an access point as the fundamental focal point.
  • In an infrastructure mode of all wireless nodes network attach to an entrance point.
  • Generally each and every node which is attached to the access point possesses the similar service set identifier identical to the access point.
  • When the access point is facilitated with WEP they possess similar WEP key or other certification parameters.
  • But in an ad-hoc mode network the wire less do not require an access point.
  • It can straightly line up with all other wireless nodes directly.
  • All the nodes in an ad-hoc network boast identical channel and SSID.
  • Wireless card is created with the IEEE 802.11 customary which commences low-level specifications for all other wireless networks to function properly.
  • Previous lines up controllers are normally the well-matched with previous variant of the standard, while both current and old standards are supported by newer cards.

Specifications of Wireless Card

  • Wireless card transmits power which is calculated in dBm.
  • It is utilized for in marketing materials as the wireless data transfer rates are measured in Mbit/s and these range from 2 Mbit/s to 54 Mbit/s.
  • Wireless network level measurement includes standards such as 802.11g, 802.11b, 802.11g and more.
  • It also provides data transfer speeds which is equivalent to 802.11a up to 54 Mbit/s and the wider 300-foot range of 802.11b, and is diffident attuned with 802.11b.
