This process needs to be completed through beam scanning during the link establishment phase, introducing additional latency. Generally, once the analog beam is blocked or moves, causing misalignment, the link quality of the system will rapidly degrade or even terminate. Therefore, the communication reliability of ABF is not as good as that of DBF.
