3.4.2 Power Level Estimation (Link Budget)
This section describes the calculation of the expected UL and DL reception power levels. For
this sample investigation a standard model of an area of 50 x 50 sqm (25,000 sqft) (resulting
in a coverage radius of 34m (110 ft)) has been chosen to provide coverage and capacity for.
The model to calculate the propagation losses in indoor environments is described in section
3.4.1. In areas blocked by walls the simplified model is extended for non-line-of-sight
conditions that cause Rayleigh fading. These conditions request an extended margin of
11dB. The propagation model assumptions are summarized in Table 6 Propagation
