※Wireless Module and Wireless Antenna
Wireless antennas:
The module adopts the latest 802.11n Dual-Band technology.
DUT does not support simultaneous transmission.
The transmitter of the module is powered by host equipment (Detector).
The antennas are 2 printed-dipole and correlated antennas.
Does not support beamforming.
※Wireless module:
The end product will use the in original certified transmitter module and will keep the original
authorization condition except the change in antenna of the module during the final end
product assembly.
Data transmission is always initiated by software, which is the passed down through the
MAC, through the digital and analog baseband, and finally to the RF chip. Several special
packets are initiated by the MAC. These 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 is being transmitted. In
other words, this device automatically discontinues transmission in case of either absence of
information to transmit or operational failure.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment. This transmitter must not be co-
located or operated in conjunction with any other antenna or transmitter.
When installing it in a mobile equipment
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement
C to OET65. This equipment has very low levels of RF energy that it deemed to comply
without maximum permissive exposure evaluation (MPE). But it is desirable that it should be
installed and operated keeping the radiator at least 20cm or more away from person’s body
(excluding extremities: hands, wrists, feet and ankles).
When you use the detector with wire mode, the wireless function is automatically off.
※5150~5250 MHz band is restricted to indoor operations only.
