FCC ID: EJM-AP1210

Operational Description
The transmitter of the EUT (Intel Wireless Gateway II) is powered by power adapter. The
antenna is Dipole antenna. There is no antenna connector. 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.

ADT No.910418R02
