摘要： An object is to provide an RF module arranged such that a user can understand the state of the RF module even when the user handles the RF module in a place at a distance from a BB module and that the user can understand the state of the RF module even if, for example, the BB module has some trouble. The RF module is connectable to the BB module which is disposed external to the RF module. The RF module includes a module controller configured to output data indicative of the state of the RF module exteriorly of the RF module without use of the BB module.

摘要： One example discloses a near-field wireless device, including: a near-field antenna having a first conductive surface and a second conductive surface; wherein the conductive surfaces are configured to carry non-propagating quasi-static near-field electro-induction (NFEI) signals; a tuning circuit coupled to the near-field antenna and having a set of tuning parameters; a controller coupled to the tuning circuit; wherein the controller is configured to monitor a loading of the near-field antenna; wherein the controller is configured to adjust the tuning parameters if the loading is different from a preselected loading; and wherein the controller is configured to set a user present status in response to a predefined threshold change in the set of tuning parameters.

摘要： A wireless sensor includes a radio frequency (RF) front end, a sensing element, and a processing module. The RF front end receives a request for sensed data from a sensing computing device and sends a coded digital value to the sensing computing device via the RF signal. The sensing element senses an environmental condition of an item. The processing module determines an effect on an operational parameter of an RF front end of the wireless sensor as a result of the sensing element sensing the environmental condition and while receiving the RF signal. The processing module also adjusts tuning of the RF front end to mitigate the effect on the operational parameter and equates an amount of adjusting of the tuning of the RF front end to a coded digital value.

摘要： A wireless terminal capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal. A measurement request message from a radio access network indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.

摘要： A system includes a radio frequency (RF) receiver having an input, and an antenna terminal configured to connect to an antenna. The system further includes one or more switches that switch the receiver input of the RF receiver to connect to a terminating load that is not an antenna or to an internal antenna, and noise level measurement circuitry that measures a first RF noise level across the terminating load or the internal antenna. The one or more switches further switch the receiver input of the RF receiver to connect to the antenna terminal, and the noise level measurement circuitry further measures a second RF noise level received at the antenna terminal. The system also includes a controller that determines whether an external antenna is connected to the antenna terminal based on the first RF noise level and the second RF noise level.
