    摘要： Disclosed is a compact reconfigurable channel emulator, which may be used to emulate severe fading environments and test wireless systems and subsystems for operation in severe channel environments. Examples include radios, coding schemes, diversity methods and antennas. In particular, the chamber is well suited to test hardware associated with wireless sensor deployments for these tend to be susceptible to severe fading scenarios. Moreover, the invention is significantly smaller than traditional testing instruments, and with its automation, reduces electromagnetic interference and electromagnetic compatibility testing time and costs.

    摘要： The invention is a microminiature wireless environmental sensor that has integrated both sensor and transmitter functions into one function. The basic operating principle for the device is that variable components of an RF circuit can be interfaced to the outside world environmental signals resulting in proportional changes in the transmission characteristics or transmission of data/bits from the RF transmitter circuit. This utilization of environmentally sensitive variable elements within a wireless transceiver circuit permits the fusion of both sensor and communications function into an integrated single function.
