An Individual Entertainment System (SEI) is still an electronic system, and its cables, like all of them, are potential sources of problems since the vibrations and conditions of a bus are obviously not those of a fixed installation, and the deterioration of cables is much higher than that found in a fixed installation.
The minimization of cables is the first advantage and one of the most important, especially for systems that transmit data at very high speed, it is almost an obligation, to reduce failure or maintenance points as much as possible.
The repercussion of a simple fault in a cable (damaged, pinched, has come loose due to vibrations, etc...) goes far beyond the fault itself, it must be diagnosed on site, which is why specialized personnel are required, it must be located, taking into account Bear in mind that not all the connections are visible, the spare part must be available at hand... with all this, we see that, from an operational point of view, resolving this type of breakdown is much more expensive in an individual entertainment system with cables than a wireless content distribution.
A wireless individual entertainment system is characterized by distributing all content information through its own Wi-Fi network, created from its content server and specifically dedicated to distributing content, thus fulfilling this objective of reducing wiring that we were trying.
Another of the pros of a wireless personal entertainment system is related to the type of power. In the scarce wiring that a wireless SEI requires for a bus or coach, it is limited to 24V power, therefore the possible consequences of a problem in these cables is much more controlled and its repair does not require specialized labor.
Another important advantage is related to the evolution of tablets, by taking advantage of this type of technology to enjoy an individual wireless entertainment system, at the same time taking advantage of all the enormous advances that are taking place in the market in this field. Whereas, if this were not the case and we depended on a wired system, these improvements would always depend on the manufacturer's own development department, which could represent a limitation of future development.
In short, the advantages of a wireless individual entertainment system compared to a wired system are significant enough to prefer this type of system in the same price and performance conditions as the wired alternative.
