134:. NDIS 6 supports exposing 802.11 frames to the upper protocol levels, while previous versions only exposed fake Ethernet frames translated from the 802.11 frames. Monitor mode support in NDIS 6 is an optional feature and may or may not be implemented in the client adapter driver. The implementation details and compliance with the NDIS specifications vary from vendor to vendor. In many cases, monitor mode support is not properly implemented by the vendor. For example, 79:). Monitor mode can also be used to help design Wi-Fi networks. For a given area and channel, the number of Wi-Fi devices currently being used can be discovered. This helps to create a better Wi-Fi network that reduces interference with other Wi-Fi devices by choosing the least used Wi-Fi channels. 110:
Usually the wireless adapter is unable to transmit in monitor mode and is restricted to a single wireless channel, though this is dependent on the wireless adapter's driver, its firmware, and features of its chipset. Also, in monitor mode the adapter does not check to see if the
