The concept of voice over Internet Protocol is becoming popular day by day across many parts of the world, and eventually, people are opting for this technology due to numerous advantages attached to it.
R factor and mos score are two elements related to this particular technology, and it might be confusing for certain people to differentiate between these two.
Key Takeaways
- R-factor is a numerical representation of voice quality, while MOS (Mean Opinion Score) is a subjective rating of voice quality.
- R-factor ranges from 0 to 100, with higher values indicating better quality.
- MOS scores range from 1 to 5, with higher scores indicating better-perceived quality.
R Factor vs Mos Score
R factor, also known as the Transmission Rating Factor (TRF), is a numerical scale used in telecommunications to quantitatively measure the quality of a voice transmission. Mos, or Mean Opinion Score, is a subjective rating given by evaluators to rate voice quality in scientific studies.
The R factor is a term that represents a quality assessment method of voice over an Internet Protocol system. Whenever this system is employed, certain objective phenomena that are related to this technology are assessed on a scale of 1 to 10.
The methodology of this particular method makes it unique from others. The Mos score is basically a method by which VOIP or voice-over-Internet Protocol technology is assessed.
Eventually, it is seen how compatible the technology is as per the needs of the users. In this particular method, certain subjective questions are asked from the users who have been using this particular technology, and eventually, the assessment is done.
Comparison Table
| Parameters of Comparison | R Factor | Mos Score |
|---|---|---|
| Meaning | The term refers to an assessment method that is used to assess voice over Internet Protocol system. | The term refers to another assessment method having subjective technology to assess VOIP. |
| Full form | No such full form is available | Mean opinion score |
| Nature | The nature of this assessment technique is objective. | The nature of this assessment technique is subjective. |
| Methodology of assessment | The system is assessed based on certain parameters like the signal or the delay in catching signals. | The system is assessed based on the subjective feedback of customers. |
| Scale of parameter | It is measured on a scale of 1 to 100. | It is measured on a scale of 1 to 5. |
| More valued by customers | It provides a more realistic assessment therefore it is valued at a larger extent. | It is valued by the customers but slightly less than other counterparts. |
What is R Factor?
The voice-over-Internet Protocol has become a new sensation in the world of technology, and due to multiple service providers being available, it becomes very crucial to assess each and every service in order to get a hold of the best one available.
In order to conduct this particular assessment, certain methods are used, and the R factor happens to be one out of these methods.
The R factor method basically happens to use an objective type of study in order to find out the strength and weaknesses of the network available, and to do so, it keeps in mind all the variable factors that can affect the network, such as the signal strength and the delay in catching strength.
This assessment is done on a particular scale of 1 to 100, and the results are heavily relied upon by not just the customers but by the consumer serving companies as well.
It is very easy to conduct this kind of assessment as the objective study does not only take less time but also happens to be cost-effective as well.
What is Mos Score?
The Mos Score basically stands for mean opinion score and simply refers to another assessment method of assessing the voice over Internet Protocol system.
The nature of this particular study happens to be very subjective as it does not rely upon all the variable factors but rather takes into account the feedback from the customers.
The customers are provided with certain subjective questions, and based on their answers or rating, the assessment is done on a one to five scales.
While on one side this study happens to be very accurate as it takes into account the real experiences of the users, it is still a difficult task to carry out this particular assessment as it not just consumes a lot of economic resources but also takes a lot of time and sometimes the results might not be as accurate as expected as there is a chance of customers giving bad reviews just because of their own personal experiences.
Due to this particular reason, this study is sometimes backed by another kind of study so as to confirm the reliability.
But if conducted properly, this city can result in two a proper assessment of a network system in order to know all the advantages and disadvantages attached to it.
Main Differences Between R Factor and Mos Score
- R Factor is an objective method of assessing VOIP, while on the other hand, Mos Score is a subjective method.
- R Factor uses a one to hundred scale in order to assess the network quality, while on the other hand, Mos Score uses one to five scales for assessment.
- R Factor is mostly relied upon by the customers, while on the other hand, Mos Score happens to be more accurate.
- R Factor conducts an objective study keeping in mind all the variable factors, while on the other hand, Mos Score conducts a subjective study after taking due feedback of all the customers.
- R Factor has no such full form available, while on the other hand, Mos Score stands for mean opinion score.
