How are wireless operators coping with pressures to improve profit margins in a competitive marketplace? According to ABI Research, operators have had limited options with 3G but 4G LTE should give them some new tools. In 2Q12, minutes of use showed the greatest declines compared to 2011 in Asia-Pacific (-7.36 percent), Africa (-6.3 percent), Western Europe (-2.32 percent), and North America (-2.12 percent). “For voice communications, Voice over LTE (VoLTE) enables rich media content to be overlaid over voice, while the packetized delivery of the voice data allows for greater cost of service savings,” says Jake Saunders, vice-president/Forecasting. “VoLTE services might help operators to retain a competitive portion of the mobile voice over IP market.”
