                   Operational Description
This device is a Wireless Module, which operates in 2.4GHz & 5.0GHz bands; the

maximum data rate could be up to 300Mbps which OFDM technique. If the signal to

noise radio is too poor which could not support 300Mbps, the 11Mbps data rate with

DSSS technique will be applied.


The transmitter of the EUT is powered by 5Vdc from host equipment. The antenna is

PCB without antenna connectors.


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

  FCC 15.407(c) states: The device shall automatically discontinue transmission in
case of either absence of information to transmit or operational failure. These
provisions are not intended to preclude the transmission of control or signaling
information or the use of repetitive codes used by certain digital technologies to
complete frame or burst intervals.


Applicants shall include in their application for equipment authorization a description
of how this requirement is met”



Data transmission is always initiated by software, which is then pass down through
the MAC, through the digital and analog baseband, and finally to the RF chip.
Several special packets (ACKs, CTS, PSPoll, etc…) are initiated by the MAC. There
are the only ways the digital baseband portion will turn on the RF transmitter, which
it then turns off at the end of the packet. Therefore, the transmitter will be on only
while one of the aforementioned packets are being transmitted.
