In WIFI operation, the system can be powered inductively or by batteries. This allows both short-term measurements with batteries and operating times unlimited in time using inductive operation. Evaluation Unit more info MANNER Sensortelemetrie GmbH offers various forms of a data evaluation unit. ...
Finally, we translate all the learned lessons to a freely-available capacity-planning tool for forecasting performance given a set of input parameters such as frequency, signal strength and number of users—and so, useful for estimating the cost of future deployments....
software may manage a network to place one or more selected TIMs in a sleep mode when the selected TIMs are not needed. Such selective employnent of TIMs can save power and can assist in managing signal propagation issues such as signal interference, signal strength and other propagation issues...
26. A system for measuring geological data, comprising: (A) a plurality of transceivers, each of the transceivers having at least one transmitter and at least one receiver; (B) the receivers being adapted to receive at least one electrical signal; (C) the transmitters being adapted to inject...
link to the sensor unit(s) 24. Depending on the specific RF hardware employed, some of the RF functionality may be handled by the processor 26. Of course, other forms of communication such as serial ports, USB, Bluetooth, WiFi, or another type of common communication transports could be ...
The base station may also upload or receive user data and information to a personal computer (via hard wire, bluetooth or wifi), and/or to a remote system preferably via a network connection, such as over the internet, which may be maintained and operated by the user or by a third party...
“path loss” parameter related with the transmission media andDis the distance. To empirically characterize the behavior of signal strength as a function of distance, we have performed two controlled experiments: (i) when a pair of sensors are placed on the ground and controlling the distance ...
Common smartphone antennas for WiFi and BLE have a high directionality in their radiation patterns leading to orientation-dependent antenna gains. This can result in offsets in the distance estimation depending on the relative device orientation. Additionally, external influences on signal transmission ...
