In what scenarios do operators require to add new base stations to migrate from 2G to 2.5G (GSM/TDMA to GPRS or CDMA to IS95B). I hear different versions on the topic: new cell sites "may be" necessary in some cases, or, that in other cases only upgrades(what in specific is upgraded)to "existing" base stations are required for 2.5G deployment.
What is the implication on -48Vdc power plants in all 2.5G circumstances? Where will additional or upgraded -48Vdc power plants be required to feed telecom equipment. Will the implication of 2.5G prolong the growth of +24Vdc power plants to power telecom equipment.
