What is the maximum distance of microwave communication? Coast submarine communication; 2

Range of microwave, short wave, medium wave and long wave
Ultra long wave (very low frequency) VLF 100000-10000m 3-30khz 1 Coastal submarine communication; 2. maritime navigation. Long wave (low frequency) LF 10000-1000m 30-300khz 1 Atmospheric medium and equal distance communication; 2. underground rock stratum communication; 3. maritime navigationThe communication radius of microwave communication is
It can be seen that the direct transmission distance of TV broadcast signal is limited. The farther the receiving point is from the TV station, the higher the receiving antenna needs to be erected, so as to receive the signal of the TV station. For example, when the height of the transmitting antenna is 150 meters and the height of the receiving antenna is 10 meters, even if there are no mountains or tall buildingsHow far can ultra far microwave be transmitted
The propagation distance of long wave is relatively long. The propagation distance is determined by the power of the transmitter and the ground conditions. Generally, it will not exceed 3000 km
What is the wavelength effective distance of a household microwave oven
The effective wavelength distance of domestic microwave oven is 12.2cm. Microwave oven (microwave oven/microwave), as the name suggests, uses microwave to cook. Microwave oven is a modern cooking stove which uses microwave to heat food. Microwave is an electromagnetic wave. Microwave oven consists of power supply and magnetronTransmission distance of microwave
The transmission distance of microwave can only be limited to two points that can be seen each other. Even if the transmitting antenna is set up on a 40 meter high mountain, the microwave is blocked by the "big belly" of the earth, and the transmission distance is only more than 50 kilometers. Microwave communication uses a wavelength of 0How far is the microwave channel? The distance can be viewed directly and safely
A distance of 100 meters allows safe direct viewingWhat is microwave communication
In the microwave frequency band below 10 GHz, the over the horizon communication can also be carried out by using the scattering propagation of the atmospheric tropospheric inhomogeneous body, which is called tropospheric scattering communication. Its communication distance is generally about 300 kilometers from the flat ground, and the multi station relay can reach thousands of kilometers (see scattering communication). Microwave is also widely used in space communicationWhat are the transmission modes of wireless monitoring? What is the longest transmission distance of wireless microwave
UHF SHF 3-30ghz cm wave 10-1cm UHF EHF 30-300ghz millimeter wave 10-1mm VHF 300-3000ghz silk meter wave 1-0.1mm our company produces microwave video monitoring products without relay at presentWhat is the maximum distance between the synchronous communication satellites over the equator
As long as there are three synchronous satellites. The three satellites form an equilateral triangle and make the earth an inscribed circle. In this way, the distance between the three satellites is 2 √ 3 times the radius of the earthIn terrestrial microwave relay communication, what is the distance between relay stations
According to the height specification of the relay station, there is an earth curvature calculation tool. When the drop between two points is 18 meters, the farthest transmission distance is 50km, and the relay station is generally more than half, that is, when the relay station antenna is 18 meters high, the distance between the two relay stations is about 30km
