noise is any unwanted disturbance of a useful signal that obscures its information content. Many different types of noise in data communication exist, and managing noise successfully requires the use of multiple techniques. Among the most common types of noise are electronic noise, therma...
NOISEMillimeter (mm-wave) communication is a prominent candidate to support the evolution towards fifth generation (5G) wireless systems. As such, in this paper, we study the impact of different noise type and mobility on the performance of coherent binary digital modulation schemes in mm-wave ...
Highly directional antennas are designed to focus radio-frequency (RF) signals in a very narrow beam, concentrating the signal strength in a specific direction. These antennas are the ideal model of precision in the world of wireless communication, ensuring that signals are directed exactly where th...
Over-the-ear headsets, the most common wireless headset shape, have the advantages of shielding the user from outside noise. The microphone to the headset is typically positioned like an arm in front of the user's mouth. Some headset users find in-ear stereo headsets, often called earbuds,...
Communication, the exchange of meanings between individuals through a common system of symbols. This article treats the functions, types, and psychology of communication. For a treatment of animal communication, see animal behaviour. For further treatmen

What is noise, you ask? Well, it’s an electrical disturbance that can degrade communications. We hear it many times over the phone, and even while making calls over the internet via VOIP. 2] Infrared (IR) Another wireless transmission media, or unguided transmission media, but it doesn’...
The walkie-talkie is a wireless communication tool like the mobile phone,but compared with the mobile phone,the walkie-talkie can not only communicate one-to-one,but also one-to-many,and there is no call charge during the call.
Below, we explorenetwork devices’ definition, types, functions and importance in maintaining business efficiency, security, and reliability. Network Device Definition A network device is a piece of hardware or software integral to communication between a computer and an internet network. Common network...
Yes, parity bits can be used in wireless communications to detect errors. However, due to the inherent nature of wireless channels, which are prone to noise, interference, and signal degradation, more robust error detection and correction techniques, such as forward error correction, are typically...
