Inside Wireless: How RF coverage works

Показать описание
RF Coverage is NOT equal to Beam width.. What is it then? After watching this Inside Wireless video, you'll understand what RF coverage is and how it works. The RF waves are invisible, but we can still visualize them using pseudo-colors. Many more components go into its calculation and it is wrong to say that section of a circle with angular width corresponding to the antenna beam width is a good approximation of coverage. Find out more in our latest Inside Wireless episode.

RF coverage calculation components are:
* Antenna radiation pattern
* Antenna realized gain
* RF radio output power
* Map data
* Antenna site coordinates
* Antenna down tilt, height above ground

Various online tools offer RF coverage calculations of various accuracies. Factors that are difficult to include in the calculation yet can strongly influence its accuracy are changing foliage, weather conditions, or flora passing the line of sight of a link.

Many WISPs like the idea that coverage corresponds to the beam width because it's intuitive and easy to understand. It is misleading to say the least and often leaves users confused when they get mixed results in the field deployment.

COVERAGE IS A CONTINUOUS IMAGE OF RF SIGNAL IN AN AREA.

Is it one signal inside the beam with or group of parallel same signal???

hi sir! given its gain, how can i calculate the antenna max distance coverage?
lastly, RSSI and RSRP are parameters needs to monitor? thank you

Extremely good .. can you also make a video on how QAM and OFDM work together ?

If I have say a 5 dbi antenna and I add in 30 feet of low loss cable, like LMR 400 and it drops it to ~4 dbi, with that have any effect on the radiation pattern at all? eg. can you (or does it) make a higher gain antenna have a wider beam width when it has more cable loss or is it just a power drop and it all stays the same, just less distance/coverage?

Thanks for the excellent explanation . What i can't understand..how can a 65° degrees antenna beamwidth cover a sector of 120° ?

Some segments in the video are stamped not adjacent to each other

All the pictures I've seen are red blobs. We spent all this money on red blobs 😂🤷🏽‍♂️
