Detailed Description

This class mimics the TXVECTOR which is to be passed to the PHY in order to define the parameters which are to be used for a transmission.

See IEEE 802.11-2007 15.2.6 "Transmit PLCP", and also 15.4.4.2 "PMD_SAP peer-to-peer service primitive parameters".

Note: the above reference is valid for the DSSS PHY only (clause 15). TXVECTOR is defined also for the other PHYs, however they don't include the TXPWRLVL explicitly in the TXVECTOR. This is somewhat strange, since all PHYs actually have a PMD_TXPWRLVL.request primitive. We decide to include the power level in WifiTxVector for all PHYs, since it serves better our purposes, and furthermore it seems close to the way real devices work (e.g., madwifi).
