Operator Strategies for an LTE Deployment 3 Categories for LTE Deployment of Operator Data Only Services on LTE - Data-only service used for high-speed mobile broadband - Quick deployment of LTE access without requirement of voice core solution - Consideration for the interoperability with 2G-3G data - Wireless dongles, netbook, Air cards, etc Data Only Services on LTE with 2G-3G Voice - Voice is still major revenue generator for wireless operators - Quick deployment of LTE access without the need for an entirely new voice core solution - CSFB, SVLTE must be considered depending on the current network deployment strategy Data and Voice services on LTE - Wireless data All-IP technology based on IMS - Need full LTE Coverage with new voice core solution - Multiple new functions is required to incorporate with IMS into LTE ecosystem
Operator Considerations of LTE migration Efficient use of available resources for a smooth deployment Spectrum Considerations - Need to secure additional spectrum to enhance subscriber experience and new type of service - Allocate new spectrum and refarming of existing spectrums for LTE Service - Consideration for the phase out and refarming will be difficult issue Access Network Equipment Considerations - Increase coverage and capacity, and reduce interference for seamless services - Fast network deployment for the Time to Market - Reduce the Capex and Opex through Antenna sharing Core Network Equipment Considerations - Reuse and integrate as much of their existing core network to reduce the Capex and Opex - Reduce operation complexity by combining in single nodes - Maximizes network performance by reducing the number of external interfaces
