What do you mean by frequency reuse?

Each cellular Base Station is allocated a group of radio channels to be used. These radio channels can be used by another base station which is at a suitable distance away from it.

How to Calculate Long Term Fading?

Long Term Fading calculator uses Long Term Fading = Mobile Radio Signal/Multipath Fading to calculate the Long Term Fading, The Long Term Fading formula is defined as the short-term variation is due to multipath fading and can be described by either Rician or Nakagami distribution, and the long-term fading usually follows a log-normal, or gamma distribution. The rates of fading expressed in terms of level crossing rate and average fade duration have been also obtained. Long Term Fading is denoted by M_t symbol.

How to calculate Long Term Fading using this online calculator? To use this online calculator for Long Term Fading, enter Mobile Radio Signal (R_t) & Multipath Fading (R_ot) and hit the calculate button. Here is how the Long Term Fading calculation can be explained with given input values -> 2.5 = 26/10.4.
