The LLW-4250 (hereafter referred to as this product) is a Low Latency Wireless (LLW) device based on the LLW-4150, featuring two wireless LAN modules and supporting DFS functionality. The following specifications have been changed from the LLW4150:
· DFS Detection Function: o Wireless Module 1: DFS detection function is disabled, and it performs wireless data transmission and reception. o Wireless Module 2: DFS detection function is enabled, and it does not perform data transmission. o Wireless Module 1 and 2 operate on the same channel, with the transmission permission of Wireless Module 1 (CAC, radar detection, etc.) being governed by the state of Wireless Module 2.
The wireless LAN modules are two SX-PCEAN2c units, operating in the 2.4 GHz band, W52 band, W56 band, and W58 band. One wireless LAN module is used for communication, while the other is dedicated to DFS detection and does not perform transmission. The hardware configuration is the same as the LLW-4150.

7. Federal Communication Commission Interference Statement
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.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
– Reorient or relocate the receiving antenna. – Increase the separation between the equipment and receiver. – Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected. – Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
This device meets all the other requirements specified in Part 15E, Section 15.407 of the FCC Rules.
Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment must be installed and operated keeping the radiator at least 20cm or more away from person’s body.
Compliance with FCC requirement 15.407 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 and can radiate radio frequency energy and, if not installed and used in accordance with the instruction packet. Therefore, the transmitter will be on only while one of the aforementioned packets is
