In telecommunications when a RF signal is transmitted, it gets reflected in all directions. It takes different paths, for example, it can hit a wall, ceiling, glass, etc. Signals get reflected or refracted or absorbed by these obstacles. During this process, multiple wavefronts of the signal are creating, therefore duplicating the original signal. This is called Multipath. At the receiver end, there will be duplicates of the original signals from different reflections. This is called Multipath Fading or Multipath distortion.
With the rollout of fiber-fed antennas, RETs, and DAS systems seemingly making RF systems more complex, one simple item remains. RF is transmitted out of an antenna. It may be a large antenna with 18 sectors built into it or a small 100cm square antenna, but each antenna holds to the physics of antenna design. Understanding the basic antenna principles allows engineers to have that ingrained sanity check for system design and optimization.
Engineering discussions tend to focus on how to improve the KPIs in the sense of network quality, reduce drops, improve accessibility, etc. Fixing coverage holes is always noted, but this tends to be fixing coverage the "right" way, which is typically the long term capital improvement. Long term network fixes come through large scale site build, low-band spectrum acquisition, improved hardware deployment, or alternative network types which is typically large capital expenditures.
