For optimal performance it is recommended to use those for the carrier board design or a PCB with similar specification. http://www.iteq.com.tw/wp-content/uploads/2016/09/IT-180-datasheet-201409.pdf https://www.isola-group.com/pcb-laminates-prepreg/370hr/ • Avoid routing any non-isolated conductors, ground layers or vias underneath MLE-N2 in the top layer as vias or conductors on MLE-N2 might get short circuited otherwise. 2 Guidelines for optimum antenna performance The MLE-N2 module has a built in highly effective inverted F antenna optimized for wall mount applications. 2.1 Carrier board design For optimum performance of the MLE-N2 antenna the carrier board PCB should be designed so that following dimensions are met: Board design example ITEQ IT180 carrier PCB Red diagonal striped area is a keep out area “air gap” from any solid objects or carrier board PCB material. min 5mm min 5mm MLE-N2 module min 5mm Black Area is a carrier board clearance area. No components or traces/GND planes are allowed in this area. This area should be min 5mm wide from the board edge of MLE-N2 to the opposite board edge. Please note the orientation of the antenna and MLE-N2.

No components or traces/GND planes are allowed in this area. This area should be min 5mm wide from the board edge of MLE-N2 to the opposite board edge. Top layer of carrier board PCB should be free from non-isolated GND planes, traces or vias. ITEQ IT180 carrier PCB MLE-N2 Min 5mm to solid objects under and above MLE-N2 antenna area. Note that carrier board thickness can be included in the total distance to solid objects under the antenna. I.e. for a 1.6mm carrier board standoffs needs to be min 3.4mm Min 5mm Min 5mm Document. type: Technical Note Revision: PA3 LumenRadio AB www.lumenradio.com Phone: +46 31 301 03 70 Svangatan 2B [email protected] Fax: +46 31 301 03 80 SE-416 68 Gothenburg Sweden VAT reg. no: SE556761749201 3 Compliance information 3.1 FCC information 3.1.1 Federal Communication Commission Interference Statement 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 th…
