-**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.+**Mixed Mode: **Mixed Mode transmissions can be decoded by 802.11a/g clients, providing backwards compatibility.

-**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.+**Greenfield: **This 802.11n mode is also known as "High Throughput" or "HT" mode.
