Hi, simon.waweru!
I found the following instructions on phase adjustment at cisco, and it may be useful for us.
If multiple transmit antennas are used to transmit multiple copies of the same data, the multiple copies of the data are transmitted upon arrival at the receive antenna after passing through the wireless channel
Produces different degrees of attenuation and has different phases. (Think of phase as a numeric marker, such as + 1 or - 1, and allow gray shading) It's because of the number of
Each copy of the data is transmitted by a different antenna and is reflected by different walls and devices as it traverses its path to the receiving antenna. If you reach a certain
If there are two paths with equal attenuation, but one path is in opposite phase to the other, the two paths cancel each other out. If you are
Try to receive signals from this location, which will have an adverse effect.
This conundrum prompts people to look for solutions. If the phase of each data stream is known, multiple copies of the data can be made available in advance by compensating the phase of the transmit antenna
It has the same phase when it reaches the receive antenna. Contrary to the counteracting situation, the two paths combine constructively with each other. This pre-compensated phase is the number of
A method in which multiple copies of the data have the same phase when they reach the receiving antenna is called transmit beamforming.
Transmit beamforming allows multiple copies of data to have the same phase when they arrive at the receive antenna, so that they can be superimposed for maximum effect, transmit beamforming
The signal quality obtained at the receiving end can be significantly improved. Transmit beamforming does not just passively receive the radio link it handles, but also changes it.
and improvements.
