1 Abstract
The mobile networks of most operators are witnessing an unprecedented rise in data traffic, due to an increasing consumer demand to access bandwidth intensive content on-the-go and the proliferation of a large number of mobile devices such as smartphones and tablets. This trend is exerting extremely high pressure on the capacity constrained network of operators. Faced with this challenge, wireless providers need to upgrade their network infrastructure in order to keep up with data traffic volumes and deliver bits more cost-effectively. When compared to some other upgrade options such as HSPA1, HSPA+, and WiMAX2, Long Term Evolution (LTE) provides operators with a technically superior and cost effective solution to deliver true mobile broadband experience. Although LTE standards and the ecosystem have not yet evolved fully and an upgrade requires significant capital investment, operators can still reap tremendous benefit by formulating the right migration strategy. A focus on key priorities such as pricing, rollout strategy, network sharing, and spectrum policy will be instrumental in the successful rollout of LTE. Having realized its potential, several operators across the globe have already deployed LTE commercially and many more are in the fray.

2 The Need for LTE
The increasing proliferation of a range of Internet enabled mobile devices, such as tablets, smart-phones, and e-readers has added to the rising consumer need to access rich content on the go. This phenomenon has resulted in the explosion of mobile data traffic exerting an unprecedented demand on the network of wireless operators (see Figure 1). Driving this boom will be the increasing consumption of mobile video, which will consume nearly 66% of all mobile data traffic by 20143. Bandwidth intensive applications, especially those based on video, expose the capacity bottlenecks and the gap which customers are increasingly facing between peak rates in perfect conditions and real everyday experiences. It is, therefore, imperative for operators to ensure that the average user’s mobile experience is not compromised especially in high traffic areas.

In order to enhance subscriber experience, prepare access networks for the onslaught of data intense applications, and reduce operational expenditure, operators will need to upgrade their networks sooner or later. For doing so, they have multiple technology options such as WCDMA 5, HSPA, HSPA+, CDMA2000 EV-DO6, WiMAX and LTE to choose from. The migration strategy of each operator is likely to be different and will be based on several factors such as the existing state of their networks, current and projected data demand, costs considerations, and spectrum availability....
