Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. . Typical effects include queueing delay, packet loss or the blocking of new connectio
Link adaptation, comprising adaptive coding and modulation (ACM) and others (such as Power Control), is a term used in wireless communications to denote the matching of the modulation, coding and other signal and protocol parameters to the conditions on the radio link (e.g. the pathloss, the interference due to signals coming from other ...
Precoding is a generalization of beamforming to support multi-stream (or multi-layer) transmission in multi-antenna wireless communications. In conventional single-stream beamforming, the same signal is emitted from each of the transmit antennas with appropriate weighting (phase and gain) such that the signal power is maximized at the receiver output.
Web performance optimization (WPO), or website optimization is the field of knowledge about increasing web performance. Faster website download speeds have been shown to increase visitor retention and loyalty [ 1 ] [ 2 ] and user satisfaction, especially for users with slow internet connections and those on mobile devices .

In one hand, BER performance of turbo codes is influenced by low codes limitations. [34] LDPC codes have no limitations of minimum distance, [ 35 ] that indirectly means that LDPC codes may be more efficient on relatively large code rates (e.g. 3/4, 5/6, 7/8) than turbo codes.
A study confirmed that side effects like pancreatitis and kidney damage are possible while taking GLP-1s like Ozempic. Here's what a doctor wants you to know.
Salk Institute researchers have identified a key protein that may help users of GLP-1 drugs such as Ozempic and Wegovy maintain muscle mass while losing weight.
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]
