RF technology allows a set of frequencies to be used in other cells, as long as the cells aren't bordering each other. It is possible for numerous callers in one area to use the same frequency because calls can be switched to the closest base station with that particular frequency. This ...
CO2laser–microwave double resonance (LMDR) spectroscopy with an intense electric field was applied to the NH3molecule. Using infrared transitions in ... K Tanaka,H Ito,T Tanaka - 《Journal of Chemical Physics》 被引量: 0发表: 1987年 Lamb dip and infrared–radio frequency double resonance spe...
A tunable color center laser has been used as the infrared radiation source for infrared-radio-frequency double resonance spectroscopy. The A 1– A 2 splitting ( J, K = 1, = 1 and J, K = 2, = 1) in the ν 4 vibrational state of CH 3F has been studied. This technique has also...
The utility model is suitable for an intelligence house electronic equipment field provides a radio frequency control's infrared companion of intelligent house, including controlgear, with controlgear wireless connection's radio network gateway, with the radio network gateway is connected with infrared ...
RFID Access Control Software refers to a software application designed to facilitate and manage access control systems using RFID (Radio Frequency Identification) technology operating in the UHF (Ultra-High Frequency) range. This software enables organizations to control and monitor the entry and exit ...
(0.0003-micrometre wavelength).Propagatingat such high frequencies, optical wavelengths are naturally suited for high-rate broadband telecommunication. For example,amplitude modulationof an optical carrier at the near-infrared frequency of 300 terahertz by as little as 1 percent yields a transmission ...
which would increase complexity and cost. This would convert the 2.2 GHz frequencies down to a frequency that the RTL-SDR can receive (below 1.766 GHz). Alternatively, we could simply recommend that customers interested in S-band reception instead use another SDR such as the HackRF, PlutoSDR,...

The system, submerged in water, is excited with a pulsed laser working in the Mega-Hertz frequency range and tuned to match both an optical and acoustic resonance of the system. The laser interacts with the carbon nanotubes embedded in the shell of the polymeric micro-bead generating heat. ...
