Accoding to the model of the average distribution of the wireless resource and voice traffic in busy hour

we discussed the inflection point of wireless resource efficiency and the enlarging threshold for GSM network

in association with the half-rate

the used dynamic PDCH

the distributing of voice and data traffic. If the wireless resource efficiency of single cell is over 110%

the quality of data service will become worse. To ensure the excellent communication quality of the subscriber

it suggests that the whole network should be enlarged by projecting when the wireless resource efficiency of it is more than 70%

and the single cell should be enlarged by optimizing when the wireless resource efficiency of it is over 100%.
