LTE Radio Energy Consumption for VoLTE



In order to make VoLTE (Voice over long term evolution) cellular radios need to trim back energy consumption by 50%. In initial tests Metrico Wireless found that VoLTE cut the battery life by 50% and only gave about 252 minutes of talk time. ST-Ericsson has released a whitepaper highlighting a variety of design improvements that will help save battery life and address current problems with VoLTE. The major cause for power drains is the inability to operate in dual-mode, where current devices are able to flip between CDMA and LTE coverage as needed. The current problems have pushed back the VoLTE launch from a mid 2013 estimate to well into 2014 as they work to resolve the power consumption issues.
