RAC operates within the base station (BS) and plays a crucial role in managing network resources like radio channels, power, and bandwidth. It dynamically decides whether to accept or reject new connection requests from User Equipment (UEs) like smartphones and tablets. It is responsible for allocating and controlling the available radio resources to ensure efficient and. . Base station (or base radio station, BS) is – according to the International Telecommunication Union 's (ITU) Radio Regulations (RR) [1] – a " land station in the land mobile service. " A base station is called node B in 3G, eNB in LTE (4G), and gNB in 5G. They are referred to as cell towers or cellular antennas. This process ensures efficient utilization of radio frequencies and minimizes interference among users.

What is radio admission control?
Radio Admission Control (RAC) is a crucial component in wireless communication systems, particularly in cellular networks, that manages the admission of new users or connections into the network.
What is a base station in radio communications?
In radio communications, a base station is a wireless communications station installed at a fixed location and used to communicate as part of one of the following: a wireless telephone system such as cellular CDMA or GSM cell site. Base stations use RF power amplifiers (radio-frequency power amplifiers) to transmit and receive signals.
What is the RAC process?
The RAC process typically involves the following steps: Connection Request: When a new user or device wants to establish a connection with the cellular network, it sends a connection request to the base station (eNodeB in LTE or gNB in 5G) or the access point.
What does RAC do when a connection request is accepted?
Resource Allocation: If the connection request is accepted, the RAC allocates the necessary radio resources to establish the connection. This involves assigning frequency channels, time slots, transmit power levels, and other relevant parameters required for the communication session.
