    摘要: In a wireless network in which communication devices are configured to use a first guard interval between symbols or a second guard interval between symbols, wherein the first guard interval has a length shorter than a length of the second guard interval, a field is generated to indicate a set of one or more modulation and coding schemes (MCSs) supported by a first device in the wireless network and to indicate whether each of the one or more MCSs is supported when using the first guard interval. A data unit that includes the field is generated and transmitted to a second device in the wireless network.

Each pattern can include at least one pixel sensitive in a first spectrum region, at least one pixel sensitive in a second spectrum region, and at least one pixel sensitive in a third spectrum region. The image sensor integrated circuit can be configured to capture a frame of image data by reading out a plurality of analog signals. Each read out analog signal can be representative of light incident on a group of two or more pixels of the plurality of pixels. The image sensor integrated circuit can be further configured to convert the plurality of analog signals to a plurality of digital signals and to store the plurality of digital signals in a memory. The indicia reading terminal can be operative to process the frame of image data for attempting to decode for decodable indicia.
