A method of reconfiguring a radiofrequency-based sensing system comprising at least two nodes (110a-f), wherein the at least two nodes (110a-f) are arranged for transmitting and/or receiving a radiofrequency signal for presence and/or location detection and for performing network communication in an environment; wherein the method comprises the steps of: - obtaining a signal indicative of a level of accumulation of radiofrequency transmission affecting elements in proximity of at least one of the at least two nodes (110a-f); wherein the propagation of the radiofrequency signal is adversely affected by the radiofrequency transmission affecting elements; and wherein the radiofrequency transmission affecting elements are accumulated on the surface of the at least one of the at least two nodes (110a-f); - determining whether the level of accumulation exceeds a threshold; and wherein if the level of accumulation exceeds the threshold; - determining, based on the obtained signal, which one of the at least two nodes (110a-f) to act as a transmitter to transmit the radiofrequency signal for presence and/or location detection and which one of the at least two nodes (110a-f) to act as a receiver to receive the transmitted radiofrequency signal for presence and/or location detection, and - instructing the determined one of the at least two nodes (110a-f) to act as a transmitter and the determined one of the at least two nodes (110a-f) to act as a receiver. wherein the method comprises the steps of: - obtaining a signal indicative of a level of accumulation of radiofrequency transmission affecting elements in proximity of at least one of the at least two nodes (110a-f); wherein the propagation of the radiofrequency signal is adversely affected by the radiofrequency transmission affecting elements; and wherein the radiofrequency transmission affecting elements are accumulated on the surface of the at least one of the at least two nodes (110a-f); - determining whether the level of accumulation exceeds a threshold; and - obtaining a signal indicative of a level of accumulation of radiofrequency transmission affecting elements in proximity of at least one of the at least two nodes (110a-f); wherein the propagation of the radiofrequency signal is adversely affected by the radiofrequency transmission affecting elements; and wherein the radiofrequency transmission affecting elements are accumulated on the surface of the at least one of the at least two nodes (110a-f); - determining whether the level of accumulation exceeds a threshold; and wherein if the level of accumulation exceeds the threshold; - determining, based on the obtained signal, which one of the at least two nodes (110a-f) to act as a transmitter to transmit the radiofrequency signal for presence and/or location detection and which one of the at least two nodes (110a-f) to act as a receiver to receive the transmitted radiofrequency signal for presence and/or location detection, and - instructing the determined one of the at least two nodes (110a-f) to act as a transmitter and the determined one of the at least two nodes (110a-f) to act as a receiver. - determining, based on the obtained signal, which one of the at least two nodes (110a-f) to act as a transmitter to transmit the radiofrequency signal for presence and/or location detection and which one of the at least two nodes (110a-f) to act as a receiver to receive the transmitted radiofrequency signal for presence and/or location detection, and - instructing the determined one of the at least two nodes (110a-f) to act as a transmitter and the determined one of the at least two nodes (110a-f) to act as a receiver. <EOS>
