As the market is taking off driven by early LTE efforts, LTE revenues have reached over $ 2.1 Billion, up from $ 0.6 Billion in 2010. However, the present LTE infrastructure revenue only accounts for 4 % of the overall 2G/3G/4G cellular network infrastructure market. However, operators are increasing starting initiatives to rollout 3G HSPA +, LTE, edge routing, VoIP as well as video services. Developed markets, such as North America, Japan and several Tier 1 operators in Western Europe, Middle East and Asia Pacific are the major drivers behind LTE growth. Growing at a CAGR of over 45 %, global LTE infrastructure revenues will account for more than 13 Billion USD by 2015.
A comparison between RAN (E-UTRAN) and core network equipment (EPC) revenues indicates much higher investments for the E-UTRAN Infrastructure with E-UTRAN investments accounting for over 91 % of the total revenue, the key reason for this being the economies of scale for off the shelf IP equipment commonly utilized in EPC infrastructure.
