MAKING THE BEST OF A TECHNOLOGY THAT'S HARD-PRESSED

摘要

Although today's conventional 802.11n may struggle to route high-definition video-plus-audio streams around homes in some situations, you can take steps to maximize your likelihood of consistent success. For example, eliminate interference from other ISM (industrial/scientific/medical)-broadcast sources, ideally by focusing on the 5-GHz band if the resultant range is acceptable. Try enabling optional wide-channel, 40-MHz mode to maximize per-stream throughput. Only the broad-spectrum, 5-GHz band, in which nonoverlapping channels are the norm, usually offers this feature. Wide-channel mode at 2.4 GHz, in contrast, consumes roughly 80% of the band's available footprint spectrum for one channel's allocation.
