What is the Return on 4G Investment?
The discussions on 3G and 4G hinge on a fundamental question. Will the investment make sense for the industry in near term? We know that in long-term, 3G and 4G technologies offer great benefits. As this article mentions, LTE, a version of 4G, uses the radio spectrum more efficiently, improving network capacity. That will be crucial as smart-phone use explodes, straining cell networks. Consider the case of Verizon in the US which is pushing for 4G/LTE. Much of the investment for Verizon is around the purchase additional spectrum. It spent $9.4 billion for that in 2008. The same concerns apply to 3G in Pakistan.
