Re: [ns] Phy/WirelessPhy set Rb_ 2*1e6 ???????
Hi again,
That reminded me about Wavelan gold and silver products. (11Mbit 2.4Ghz 802.11b Rb_=11e6? )
Does anyone knows that product's pysical characteristics, such as capture threshold,
receive power threshold, transmission power, carrier sense threshold etc?
Are these values are within 802.11b standard? If so, where one could find them?
Happy new years,
EC
PS:Sorry for eating bandwidth again.
