-**Mixed Mode: **Mixed Mode transmissions can be decoded by 802.11a/g clients, providing backwards compatibility. In Mixed mode, 802.11n devices transmit a legacy format preamble, followed by an HT format preamble and a legacy radio signal. A Mixed mode device must also send legacy format CTS-to-Self or RTS/CTS (Request to Send/Clear to Send) frames before transmitting. These mechanisms let other 802.11a/b/g devices sense a busy network medium and wait for another turn to transmit. This alows for backwards compatiblity with earlier protocols, but reduces throughput, compared with Greenfield, or GF-BRCM modes.

-**Greenfield: **This 802.11n mode is also known as "High Throughput" or "HT" mode. In this mode, the protocol improves efficieny by using a high throughput modulation method and a shorter preamble. Neither of these is supported on 802.11a/b/g devices. This preamble mode compromises backwards compatiblity and can reduce throughput on some 802.11n devices not fully compatible with the standard.

 In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates. In reality, most claims of big increases in transfer rates are likely exaggerated. QAM links are more susceptible to noise. As a result, Turbo QAM is generally only useful in very low-noise/interference wireless environments. Many people report it being effective on line-of-sight links of up to about 25 feet. Vendors claim the range with Turbo QAM may improve when beamforming is used. You may need to experiment to see what works best on your network. \\
