Abstract: An electromagnetic interference (EMI) shield may include a frame configured to be coupled to a printed circuit board (PCB). The frame may include a horizontal body and a plurality of vertical walls extending perpendicularly from the horizontal body. The plurality of vertical walls defines a portion of a perimeter of the EMI shield, the perimeter including a concave corner defined virtually by a first and second vertical wall of the plurality of vertical walls. The first vertical wall does not extend all the way to the second wall and an opening if formed between. The first vertical wall includes an attached portion connected to the horizontal frame and an extension portion connected to the attached portion by way of a first fold. The extension portion at least partially overlays, abuts, and extends beyond the attached portion toward the second wall thereby at least partially covering the opening.

Abstract: Examples described herein provide selective filtering by a network device for continuous 5 GHz and 6 GHz operation. Examples may include receiving, by the network device, a first signal in a 5 GHz band, and generating, by the network device, a second signal in a 6 GHz band. Examples may include selecting, by the network device, a first filter or a second filter to be applied the first signal in the 5 GHz band, wherein the first filter allows a lower frequency band to pass than the second filter in the 5 GHz band, selecting, by the network device, a third filter or a fourth filter to be applied to the second signal in the 6 GHz band, wherein the third filter allows a lower frequency band to pass than the fourth filter in the 6 GHz band, and simultaneously applying, by the network device, the selected first or second filter to the first signal and the selected third or fourth filter to the second signal.

Abstract: An example method for selectively filtering Wi-Fi signals is presented. A first radio and a second radio of a wireless networking device (WND) are respectively operated on a first channel and a second channel. The first channel and the second channel are respectively within a first sub-band of a first frequency band and second sub-band of a second frequency band. A control unit of the WND may select one of a first filter or a second filter based on the first channel, and one of a third filter or a fourth filter based on the second channel. After the filters are selected, signals over the first channel are communicated through a selected one of the first filter or the second filter, and signals over the second channel are communicated through a selected one of the third filter or the fourth filter.
