Hi Pix how are you?
HR=70%, this is the percentage of the idle tch. Once this percentage become less, the half rate time slots will work.
We can avoid the confusion by saying that we have 10 rooms (time slots) in a hotel (TRU). The first three subscribers will be given a whole room for each. Any additional subscribers will be given 1/2 room (two people in one room).
The capacity of the Hotel, therefore is 14 subscribers
3 living alone
14 living in pairs
therefore, the HR traffic should be more !
Half rate traffic = people living in sharing rooms.
But in the statistic, the full is always more ! even if there is congestion (whole capacity is utilized)
