commonly referred to as radiofrequency (RF) radiation. RF radiation falls under the non-ionising spectrum, making it less harmful compared to ionising radiation. Additionally, the power levels emitted by mobile devices are relatively low, well below the threshold for causing any immediate health effe...
Public sentiment towards the police is a matter of great interest in the United States, as reports on police misconduct are increasingly being published in mass and social media. Here, we test how the public’s perception of the police can be majorly sha
This is because of the fading effect and Doppler shift of the transmitted frequency, specifically in cellular mobile radio systems and vehicle to vehicle communications. This paper presents the modeling, simulation, and then characterization of a cellular mobile radio multipath channel over its time ...
Trunked radio systems for voice communications can be easily found when browsing the spectrum with an SDR. Listening to a voice communication is easy, but actually following a conversation along is almost impossible to do manually. This is because in a trunking system the frequency in ...
And the future is always, always on the minds of wireless experts. Keep reading for glimpses into the next era of cell communications, beyond even today's freaky-fast 4G. 3G By Any Other Name All carriers in the U.S. offer service that's faster than the 3G standard. They call these ...
Latency is important in communications with a high degree of interactivity, such as online gaming or the real-time control of vehicles or industrial equipment. It is related to the speed of the network and the distance travelled by the message. Satellite data systems, for example, can achieve ...
According to news reporting from Beijing, People's Republic of China, by VerticalNews journalists, research stated, "Ultra-Reliable and Low-Latency Communications (URLLC) has attracted considerable attention because of its potential applications in factory automation, automated driving, and telesurgery ...
Control™ topology By Chris Glaser Applications Engineer Introduction A common requirement in automotive, communications equipment and industrial markets is to avoid interfering with specific frequency ranges, such as the AM radio band, to minimize disturbances for sensitive electronics, such as sensors....
Prominent among these possible extensions is the expansion of the ICS packet suite to include those protocols in the wireless domain such as Wi-Fi (802.11), Bluetooth, Zigbee, and other protocols that utilizes proprietary Radio Frequency. 展开 ...
This frequency-switching system improved radio guidance of torpedoes. The idea was about two decades ahead of its time, as it wasn't until the invention of the transistor by Jack Kilby of Texas Instruments that the U.S. Navy used the idea in secure military communications. Fifty years later...
