Technical Description

The transmitter of the EUT (802.11A+G Wireless Access Point) is powered by power
adapter and connected with managing computer through RJ45 port. The antenna is
Dipole with reversed antenna connector and PIFA antenna with UFL antenna
connector. Under normal use condition, the user has to keep at least 20cm
separation distance between radiator and the body of the user.
This device is a 802.11a+802.11g Dual Band Wireless Access Point which operates
in both of the 5GHz and 2.4GHz bands and can transmitting simultaneously, the
maximum data rate could be 54Mbps.
For more detailed instruction, please take a look at the user’s 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 hoe 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.
