. The first implementation was designed to help compensate for the performance loss of higher-speed 802.11g devices when they share a wireless network
Wireless LAN
A wireless local area network links two or more devices using some wireless distribution method , and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network...

 with slower 802.11b devices.

Later implementations are marketed as Nitro MX Xtreme which adds proprietary frame
Data frame
In computer networking and telecommunication, a frame is a digital data transmission unit or data packet that includes frame synchronization, i.e. a sequence of bits or symbols making it possible for the receiver to detect the beginning and end of the packet in the stream of symbols or bits...

-bursting
Burst mode (computing)
Burst mode is a generic computing term referring to any situation in which a device is transmitting data repeatedly without waiting for input from another device or waiting for an internal process to terminate before continuing the transfer of data.In the case of DMA, the DMA controller and the...

Data compression
In computer science and information theory, data compression, source coding or bit-rate reduction is the process of encoding information using fewer bits than the original representation would use....

 and point-to-point side session technology for a claimed 140 Mbit/s throughput
Throughput
In communication networks, such as Ethernet or packet radio, throughput or network throughput is the average rate of successful message delivery over a communication channel. This data may be delivered over a physical or logical link, or pass through a certain network node...

In telecommunications and computing, bit rate is the number of bits that are conveyed or processed per unit of time....

. The point-to-point side session technology is called DirectLink, which creates a connection between clients or from a client to a media source, such as a media server, and avoids the access point
Wireless access point
In computer networking, a wireless access point is a device that allows wireless devices to connect to a wired network using Wi-Fi, Bluetooth or related standards...

. It does this while staying in 802.11 Infrastructure mode so the client can continue to utilize access point-based security and power-savings.

Nitro is one of several competing proprietary approaches that were developed to increase 802.11g performance in wireless
Wireless
Wireless telecommunications is the transfer of information between two or more points that are not physically connected. Distances can be short, such as a few meters for television remote control, or as far as thousands or even millions of kilometers for deep-space radio communications...
