The transition to 4G mobile services offers carriers the opportunity to monetize data in new ways. The evolution of high quality mobile video and HD voice are examples of new exciting solutions the move to 4G enables. Although, the move to OFDM based technologies will bring traffic capacity enhancements, the market continues to see innovation in network topology and infrastructure components with the addition of new products such as small cells.
The 4G technology shift does not come without a price. Challenges remain in terms of spectrum choice, the availability of compatible devices, creating viable wholesale business models, driving economy of scale for chipset technology vendors, and establishing the positioning between TD-LTE and FD-LTE variants.
