Building penetration characteristics of 880 MHz and 1922 MHz radio waves

The data gathered revealed the effects of frequency, environment, and building height on the penetration loss, as well as information about building shadow loss at each frequency. Building penetration loss averages 19.2 dB for 880 MHz and 15.7 dB for 1922 MHz. The signal strength generally increases at higher floors within the building, but tends to level off at heights above the fifth floor. Exceptions to this are found in a high-rise office complex. Building shadowing effects are generally less at 1922 MHz
