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 ...
In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...

DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files. The original purpose of DCA was to provide a common document format that could be used across multiple IBM word processing platforms, such as the IBM PC , IBM mainframes , the Displaywriter System , and the IBM 5520 Administrative ...
Tesla took heat in 2024 for sending out an insensitive email about layoffs that reportedly started with "Dear Employee." GM did not respond to questions about how it handled the Nov. 15 job cuts.
Maximum throughput scheduling is a procedure for scheduling data packets in a packet-switched best-effort network, typically a wireless network, in view to maximize the total throughput of the network, or the system spectral efficiency in a wireless network. This is achieved by giving scheduling priority to the least "expensive" data flows in ...
The employer sets aside an allowance for each employee in the form of a QSEHRA. Employer contributions go in tax-free, and employees receive qualified reimbursements tax-free. QSEHRAs: Eligible ...
