Trilogy 3 MPCI
M3AWEB/56GA
Product Specification
WLAN Modulation and Channel Data Rates
Four modulation formats and data rates are specified by the IEEE 802.11b
specification. The basic access rate is based on 1 Mbit/s Differential Binary
Phase Shift Keying (DBPSK) modulation. The enhanced access rate is based on
2 Mbit/s Differential Quaternary Phase Shift Keying (DQPSK). The extended
Direct Sequence specification defines two additional data rates. These rates are
based on the Complementary Code Keying (CCK) modulation scheme for 5.5
Mbit/s and 11 Mbit/s.

WLAN Power Requirements
The Adapter is able to work with the standard Mini-PCI 3.3V +/- 5% power source. The
Adapter’s current consumption depends on the operating state. The operating state is
controlled by the Adapter’s driver software and the Adapter’s CPU. The pulse
characteristics, and peak inrush current depend on the capacitance and resistance of
the host power supply. The Adapter presents a capacitive load of approximately 20 uF.
Noise on the 3.3 V power supply should be below 50 mV RMS.
