WebJun 27, 2024 · A macrocell is part of the radio access network (RAN) and provides radio coverage for the cellular network. It transmits and receives radio signals using Multiple-Input Multiple-Output (MIMO). It operates through an antenna mounted on a tower, or 5G transmitter mast, typically 50 to 200 feet tall. A macrocell array is an approach to the design and manufacture of ASICs. Essentially, it is a small step up from the otherwise similar gate array, but rather than being a prefabricated array of simple logic gates, the macrocell array is a prefabricated array of higher-level logic functions such as flip-flops, ALU functions, registers, and the like. These logic functions are simply placed at regular predefined positions and manufactured on a wafer, usually called master slice. Creation of a circ…
