This brief analyzes the stability of the feedback interconnection of a class of dissipative linear systems, and more specifically, when the signals are sampled asynchronously and there are delays in the communication channel. The analysis is done taking into account the maximum sampling time that guarantees the preservation of the small gain (MASG) values. This brief proves that this property holds in the presence of constant delays and can be preserved under certain conditions with variable delays. A $L_{2}$ -gain-based transformation is used to interconnect the systems with the aim to make them have finite $L_{2}$ -gain and guarantee the small gain theorem. With this transformation, the maximum sampling time that guarantees the stability of the interconnection is enlarged. The last part of this brief is devoted to the experimental application of this methodology for the remote control of the rotors speeds of a quadrotor. A performance analysis for the remote control is presented based on real experiments for a 3rd generation partnership project (3GPP) cellular network.
