This paper introduces methods to characterize receiver properties of cellular IoT modules. By accessing the antenna port and using bit error rate (BER) measurements, nonlinearity properties and filter characteristics of the receiver are extracted. The method provides the versatility to examine any RF module without knowledge of components and design. The information can be accessed without destruction.
A short-range low-cost Magneto-Inductive (MI) communication system is presented for wireless sensor network applications. The advantages of MI communications include the capability of communication in all conditions such as in air, underwater, and through solids. The hardware implementation and software design incorporate three coils for multi-channel receiving and transmission. Field tests have been...
This paper illustrates the use of software for monitoring and recording the effects of electrostatic discharge (ESD) on the operation of embedded systems, with the goal of facilitating root-cause analysis of resulting failures. Hardware -- based scanning techniques are typically used for analyzing the effect of ESD on systems by identifying physical coupling paths. This paper proposes software techniques...
