The introduction of 4G networks will create new opportunities for wireless operators and service providers, but will also present a range of fresh challenges. It gives service providers the chance to develop compelling new, differentiated wireless services, and potentially develop new sources of revenue.

However, introduction of next-generation wireless networks also leads to new architectural challenges such as the requirement to deliver services across different wireless network evolutions (2G, 3G, and 4G); to deliver services that are much more demanding on the network, to manage applications which generate substantially higher volumes of network traffic; and the imperative to meet raised customer expectation.
