In the online hotel management training course, the train whistles are an important part of the training module. According to Oberoi Hotels: Train Whistle in the Tiger Reserve course, the white LED signal that signals the arrival of the train whistle contains all the information required for information dissemination.
The theoretical part of the HBR Case Solution Solutions Course which is given by Eric James presented a theory on the radio wave propagation to the sound signals. He said that the radio waves could have wavelengths varying from one wavelength to the next which makes the signals distinct, where the sound signals only have one wavelength of information, hence, the words may be heard by more people. He also explained that sounds can travel in spaces where signals cannot. This is where the sound signal can travel in the air and reach the destination where the person’s ears were located.
When this theory was applied in the case study solution, the connection between the whistles and the frequencies was explained. The white LED message would not be heard where the white LED display was in contrast to the signal that was going through the air. The theory was used to explain that the whistles would emit sounds that have the same frequency as the signals that were traveling through the air.
The whistles could still signal their arrival even if the frequencies were different. It was clear that the theory had made a significant difference in the programming used in the curriculum. The theory was then used to explain how the signals that were coming through the air could be used to communicate with people. This was done with the use of a controller, which was actually a digital signal processor.
The Digital Signal Processor or DSP is a set of computers that can be programmed to perform any function. The DSP can be used to produce any kind of signal that the programmer wants. The programmable software can be used to program the output of the DSP into an analog signal. From this information, the programmer can then determine whether the whistles can be heard or not.
By using a digital signal processor, it was possible to broadcast the message to every room of the hotel by listening to the radio. By listening to the radio, the DSP could then determine if the tones in the air were heard by the participants in the room.
In the HBR Case Study Solution, it was not really difficult to modify the program of the Digital Signal Processor, since the method used by HBR presented a clear example of a change in programming that could be done. According to the Oberoi Hotel Management Training Course, the DSP has been modified into a computer program that can be used to control the radio signals which are transmitted to the participants. The program can also be used to control the speaker phone and switch the speakers to the required channel.
The speaker phone was designed to be used to control all communication systems in the hotel. It will be the main way through which the guests can access to the system. As the company decided to use this system, it was necessary to understand the needs of the guests to make sure that they will be satisfied with the communication system.
This aspect of the project has been discovered to be quite an interesting part of the HBR Case Study Solution. The participants were then given the choice to either ask for a white LED display in a room where the speaker phone has not been programmed, or they can choose to get one which is already programmed to the frequency of the white LED display in the room. This was also done so that the guests could make a choice about the kind of communication system they want for their room.
