A Real and Present Wireless Danger

…wings. Results were compared to calculations made using free-space propagation method. Results showed that free-space overestimated measured fields of interference in gyprock rooms, and along corridors of both gyprock and clay-block construction. However, the free-space model underestimated field of interference in clay-block rooms, and in below-ground corridors. Therefore administration of hospitals should pay a lot of attention to how hospital buildings were build, and what type of medical equipment is being used in those hospitals.
