Operational Description

The transmitter of the EUT (EZ Connect 2.4GHz 11Mbps Wireless PCI Card) is

powered by host equipment via a PCI slot interface. The antenna is Dipole antenna,

and the antenna connector type is Reversed SMA. Under normal use condition, the

user has to keep at least 20cm separation distance between radiator and the body of

the user.

The other instruction, please have a look at the users manual.

DSSS Information
This device is Direct Sequence Spread Spectrum, the data is mixed by

pseudorandom code which is an orthogonal code. The mixed data is digital

modulated by BPSK and QPSK technique depends on the data rates.

The CCK coding is applied for increasing the data rate, and also the processing gain

will be increased. The bit rates are 1,2,5.5,11Mbps, the symbol rates are

1,1,1.375,1.375Mbps, the chip rates are always 11Mbps.

So, the Chip/symbol is 11,11,8 and 8 respectively. Although is higher bit rate, the

processing gain is lower than 10, but the CCK coding used in higher bit rate will

provide 2.2dB coding gain.
