3G traffic volumes have increased substantially since 2007, and this trend is set to continue with many drivers for further growth. As 3G traffic volumes increase, 3G operators potentially face massive challenges. There is a danger that 3G networks will quickly become swamped by traffic. 3G enhancements, such as HSPA+ and LTE, cannot come too soon. However, while HSPA+ and LTE promise substantial increases in peak data rates compared with HSPA, it is important to recognise that, in practical networks, these will not equate to similar increases in network capacity.
