How to evaluate the need to increase Internet speed?

Welcome!
Administer the network of BTS. Boss asks: "do you have enough Internet speed?" It is clear that the more the better. Have zabbix monitoring gateway, collecting statistics on traffic. What criteria to choose to define the degree of congestion of the channel and the need for expansion? Are on the subject of best practices?

One criterion - the lack of speed.
Enough for you? - so there is no need.
Not enough? - there is a need.

The percentage utilization of the channel over time. Ie the channel was loaded at 60% 4 hours 8 hours 90% within 1 hour of the 8, 30% for 3 hours.
Therefore, if the channel is loaded more than 80% more than half time(6 hours out of 8) that need to expand to 50%.
This is because some manuals? Can then determine what a normal channel download? I like the suggestion from the review, based on the normal distribution and deviations. Not seen this? - Rachael_Reiche commented on July 8th 19 at 11:41
As it is difficult and not applicable in practice.
Well, what if the channel was loaded with up to 80% more than half the time?
Why to expand?
Again, the channel extension may be required even if it is loaded on 0.1% more half the time. - earl.Weissnat commented on July 8th 19 at 11:44
