[5] [6] From the critical perspective, channel expansion theory is determined through validity claims which then result in a resolution in communication breakdowns. [7] The critical approach emphasizes the role of context in shaping individual's view toward a certain media channel: technology, organizational context, individual are all factors.
The effects of frequency-selective channel conditions, for example fading caused by multipath propagation, can be considered as constant (flat) over an OFDM sub-channel if the sub-channel is sufficiently narrow-banded (i.e., if the number of sub-channels is sufficiently large).
Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1]
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
Further research by Lan and Sie (2010), that within the category of text based communication channels, there are significant differences that should shape an instructor's choice of technology. [47] They studied the use of SMS, email and RSS and found that SMS is suitable for fast delivery, email affords greater content richness and RSS is the ...
There has been a mysterious doughnut shortage reported in Dunkin’ stores across several states, including Nebraska, Arizona, and New Mexico.
(The Center Square) – President Joe Biden blocked a $14.9 billion buyout of Pittsburgh-based U.S. Steel on Friday. The move, albeit not surprising after a year of negotiations that left the ...
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location.
