Information microwave is:
a / mode radio communications, use of ultra-high frequency bands, transmitting multiple channels, information on long range through the relay station.
b / Forms of information, history use radio frequency bands, transmitting multiple channels, information on long range through the relay station
c / mode digital radio communication, multi-channel signal, information on long range through the station Transitional
d / Form Radiocommunication large capacity, multi-channel signal transmission, long distance information via relay stations
Information microwave use ultra-high frequency wave bands because:
a / requirements capacity and high transmission speed
b / request information about remote distance
c / allow use of broadband and less consumption
d / communication in ultra high-frequency bands less atmospheric interference and phase nails
working frequency range of microwave communication is:
a / 30 MHz - 300 GHz
b / 3 MHz - 30 GHz
c / 30 GHz - 300 GHz
d / 30 MHz - 300 MHz.
The antennas used in microwave-sized information small size, high orientation towards high because:
a / Working at high frequency
b / Working at high frequency, small power generators
c / Signals less lossy transmission line
d / All 3 answers there are correct
d / Information Systems Mobile microwave
