چکیده انگلیسی:
Instrumental, Scientific and Medical (ISM) bands are essential to the transmission of IoT traffic
as most of the physical layers of the Wireless Personal Area Network (WPAN) and Low Power
Wide Area Network (LPWAN) families rely on them. ISM bands, however, are associated with
a myriad of problems responsible for signal degradation and pollution that lead to application
Quality of Service (QoS) issues. In this context, the use of alternative transmission mechanisms
serve as backup to traditional schemes. One of such mechanisms relies on sub-ultrasonic and
ultrasonic signals for the propagation of IoT device traffic. In this paper, we recycle a well
known acoustic modulation scheme intended to be used in legacy Public Switching Telephone
Networks (PSTNs) to support sub-ultrasonic and ultrasonic channels. This scheme becomes the
basic building block of a physical layer that is combined with other well known elements of the
IoT layered architecture. This not only includes a customized link layer but also an adaptation
layer that enables full integration with upper layers.
