802.11 LAN Card Driver
This means applications that use small packets e. Other factors that contribute to the overall application data rate are the speed with which the application transmits the packets i. The latter 802.11 LAN Card determined by distance and by the configured output power of the communicating devices.

Each represents an average 802.11 LAN Card throughput please note that the error bars are there, but barely visible due to the small variation of 25 measurements. Markers for traffic profiles of common applications are included as well.
802.11 LAN Card These figures assume there are no packet errors, which if occurring will lower transmission rate further. Channels and frequencies[ edit ] See also: List of WLAN channels These are commonly referred to as the "2.
Each spectrum is sub-divided into channels with a center frequency and bandwidth, analogous to the way radio and TV broadcast bands are sub-divided. The 2.
The latter channels have additional restrictions 802.11 LAN Card are unavailable for use in some regulatory domains. Graphical representation of Wi-Fi channels in the 2. These are discussed in greater detail on the list of WLAN channels. Channel spacing within the 2. One consequence is that stations can use only every fourth or fifth channel without overlap.
Availability of channels is regulated by country, constrained in part by how each country allocates radio spectrum to various services. At one extreme, Japan permits the use of all 14 channels for Other countries such as Spain initially allowed only channels 10 and 11, and France allowed only 10, 11, 12, and 13; however, Europe now allow channels 802.11 LAN Card through Spectral masks for It is 802.11 LAN Card correct to say that, given the separation between channels, the overlapping signal on any channel should be sufficiently attenuated to minimally interfere with a transmitter on any other channel.
Due to the near-far problem a transmitter can impact desense a receiver on a "non-overlapping" channel, but only if it is 802.11 LAN Card to the victim receiver within a meter or operating above allowed power levels. Conversely, a sufficiently distant transmitter on an overlapping channel can have little to no significant effect.
Confusion often arises over the amount of channel separation required between transmitting devices. This occasionally leads to the belief that four "non-overlapping" channels 1, 5, 9, and 13 exist under This does not 802.11 LAN Card that the technical overlap of the channels recommends the non-use of overlapping channels. The amount of inter-channel interference seen on a configuration using channels 1, 5, 9, and 13 which is permitted in Europe, but 802.11 LAN Card in North America is barely different from a three-channel configuration, but with an entire extra channel.
802.11 LAN Card Different countries define different levels of allowable transmitter power, time that a channel can be occupied, and different available channels. Most Wi-Fi certified devices default to regdomain 0, which means least common denominator settings, i. Layer 2 — Datagrams[ edit ] The datagrams are called frames. Current Frames are divided into very specific and standardized sections.

Some frames may not have a payload. The first two bytes of the MAC header form a frame control field specifying the form and function of the frame.
This frame control field is subdivided 802.11 LAN Card the following sub-fields: Protocol Version: Two bits representing the protocol version. Currently used protocol version is zero. Other values are reserved for future use. Two bits identifying the type of WLAN frame.
