Modern networked control systems integrate multiple independent feedback control loops that require guaranteed bandwidth for timely operation. However, planning the distributed control systems considering worst-case requirements leads to expensive and inefficient designs. This motivated the development of dynamic rate adaptation as a technique to support higher integration in these systems while providing an efficient use of the network bandwidth. This bandwidth can also be managed by varying the quantization used in each loop but, surprisingly, to the best of the authors' knowledge, this approach has not been explored yet. In this work-in-progress paper, we propose managing the network bandwidth varying the number of bits used to represent the transmitted variables (sensor readings and actuation values) while keeping the loop rates constant. We present the basics of the quantization-based bandwidth management as well as a qualitative discussion on the pros and cons of this method.
