1. The limiting factor is saturation of the receiver by the transmitter. When presented with a signal at a strength
above the saturation point, the receiver cannot distinguish between pulses, though no hardware damage
occurs.

2. Links longer than 30 km for the same link power budget are considered engineered links. Attenuation for such
links needs to be less than the minimum.
