السلام عليكم اخواني اعضاء المنتدى, اليكم تعريفات بعض المصطلحات المذكورة في عرض المشاركة
HW INIT GAIN - set Rx init Gain, possibly (ive seen other APs that refer to init gain as being for RX sensitivity, but I havent had any proof that this AP can have the rx improved)
CCK - sets the tx power for 802.11b
OFDM - sets the tx power for 802.11g
You would need to
FYI:
CCK (from techweb)
-------------------
(Complimentary Code Keying) A direct sequence spread spectrum (DSSS) coding method used in the 802.11b wireless LAN standard for 5.5 and 11 Mbps. The slower 1 and 2 Mbps specifications use Barker coding which has a chip rate of 11 compared to 8 in CCK. CCK also provides up to 64 coding patterns, whereas Barker uses only one. Unlike CDMA, which overlaps transmissions using different codes, CCK uses the different codes to transmit more data serially (TDM). Contrast with OFDM.
OFDM
------
(Orthogonal FDM) A modulation technique first promoted in the early 1990s for wireless LANs. OFDM's spread spectrum technique distributes the data over a large number of carriers that are spaced apart at precise frequencies. This spacing provides the "orthogonality" that prevents the demodulators from seeing frequencies other than their own. Coded OFDM (COFDM) adds forward error correction.
OFDM is used in various wireline and wireless technologies including ADSL, 802.11a, 802.11g, digital audio broadcasting (DAB), digital TV in Europe and Japan and ultrawideband (UWB).Here are the figures I have come up with by trial and error and the use of netstumbler on the 802.11b channels:
Formula for 802.11b (CCK): Desired Power x .25 = CCK setting
Formula for 802.11g (OFDM): Desired Power x .38 = OFDM setting
