Due to the complexity of wireless channel, there is certain error in classical wireless channel theoretical model, therefore wireless network planning
In work, the general method using actual measurement statistics, carries out CW tests, in actual environment using substantial amounts of test data to experience
Formula is modified, and obtains more accurately propagation loss model and coverage prediction with this.
CW (Cont inuous Wave) i.e. continuous waves.CW tests are referred to using continuous wave as signal source to wireless signal
The loss of propagation is measured and is counted.In CW tests, signal source is generally placed in the site location of planning, test receiver
It is positioned in vehicle and along the test path movement of planning.According to slow fading Changing Pattern, signal tens wavelength away from
From the change at random that upper experience is slow, its statistical law obeys logarithm normal distribution.When we are on the space length of 40 wavelength
If being averaged, it is possible to obtain its average envelope, the so-called local average of this amount, the meansigma methodss on itself and locality
It is corresponding.CW tests are one of local average main methods on acquisition length-specific.The local average for obtaining is tested using CW
The propagation model in the region can be corrected, obtain the slow fading variation characteristic of radio signal propagation in one's respective area.
