The design is usually specifically optimized to receive a certain spectrum of waves. This is one of the main reasons antennas only pick up the signals for which they’re designed — for example, ordinary car antennas typically only pick up basic AM/FM band radio, not cell phone receptions, ...
Cordless headphones incorporate one of many technologies to avoid the conventional wire that tethers the headset to the audio source. All cordless headphones use a transmitter and built-in headphone receiver to send and receive audio signals across space wirelessly. The three technologies in use are ...
This kind of headset differs from a non-stereo headset because it broadcasts two channels of audio to both ears, instead of broadcasting only a single-channel mono feed to one ear. Wireless stereo headsets can be used to transmit audio using wireless signals sent between a headphone and a ...
ultra-wideband, and ZigBee. The range of this network is normally is some meters. The best examples of this mainly include wireless keyboards, cell phone headsets
being that they support a huge capacity for fast data. Not only are they less cluttered with existing cellular data, and so can be used in the future for increasing bandwidth demands, they're also highly directional and can be used right next to other wireless signals without causing ...
There are two main types of hearing aids: Analog hearing aids These devices convert sound waves into electrical signals and then make them louder. They amplify all sounds the same way, though some may have settings you can store and switch between (quiet environments and loud environments, for...
Refinements in EEGs and implants will probably overcome this problem to some extent in the future, but for now, reading brain signals is like listening to a bad phone connection. There's lots of static. The equipment is less than portable. It's far better than it used to be — early ...
Terri Kurtzberg, co-author of the study, explained that they assumed looking at cellphones during a break would be no different from any other break—but instead, the phone may cause increasing levels of distraction that make it difficult to return focused attention to work tasks.“Cellphones ...
Second, our setup demonstrates that online media increasingly blur gender roles and can render the biological sex of social actors less important. Without tangible signals, representing the behavior of a male or female may be more important here than actually having male or female sex. Lacking ...
1.A method of wireless communication, comprising:determining a cancelation/suppression efficiency (CSE) for each cell of a set of cells;determining whether cell-specific reference signals (CRS) from a serving base station is colliding with CRS from each interfering cell of the set of cells; and...
