Wireless transmission

Definition

Wireless transmission refers to the transfer of information between two or more points that are not connected by a physical wire. This method of communication uses electromagnetic waves, such as radio frequencies, to transmit data over varying distances. In the context of data acquisition systems, wireless transmission enables the real-time collection and sharing of data from remote sensors and devices without the constraints of wired connections, enhancing flexibility and mobility in medical applications.
