What is an fdd controller?

An FDD (Frequency Division Duplex) controller is a device used in communication systems to manage the allocation of frequency bands for transmitting and receiving signals simultaneously. In FDD systems, separate frequency channels are designated for uplink (transmission from user to base station) and downlink (transmission from base station to user). The controller ensures efficient use of these frequency resources, maintains communication quality, and minimizes interference between the channels. This technology is commonly used in mobile networks and other wireless communication systems.
