Smartphone, sensor devices, cellular communication, and the Internet of Things (IoT) are recent technologies that provide new mobile location based services.
However, the interference caused by D2D devices reduces the performance of cellular communication significantly.
An Israeli company, Netline, makes a detector called the Cellular Activity Analyzer, a hand-held device that is used to monitor and detect cellular communication activity in a given area.
The wireless communication device as shown in the drawing is a cellular phone and the input/output port 32 is a USB port that projects out of the body 31 of the wireless communication device.
The idea of coupling an ultrasound device with a communication device such as Wi-Fi adapter or a cellular phone is not new.
In [8], for an overlay two-way cellular network, a spectrum sharing protocol is proposed for device-to-device (D2D) communication to maximize the sum rate of both D2D and cellular communication.
In general, devices in D2D communication may misuse both downlink and uplink resources for cellular communication [2].
Indeed, he says, chips that contain both photonic devices, such as the filter, and electronics, could be key components in all optical and cellular communication systems, as well as inside computers.
Fels, D. Cellular Communication through Light.
The trait generally involves various genes and cellular communication pathways.
At issue was GM's OnStar, the successful in-car communication device offering emergency alerts, stolen-car tracking, and a built-in phone for an annual fee of $199 (plus cellular-minute charges).
