- 2. Mobile Market Overview 2 The growing smart phone subscription base and the usage of mobile broadband to access a wide range of services and information will lead to strong growth in mobile traffic. Total mobile traffic is expected to grow annually by 40%. This equates to 8 times more mobile data traffic in 2022 than in 2016
- 3. Mobile Market Overview 3 In 2022, almost all regional mobile traffic is expected to be from data, with voice representing less than 1%. Around 95% of data traffic is anticipated to be generated by smart phones, and only 5% will be linked to PCs, tablets or routers.
- 4. Mobile Market Overview 4 Digital services are no longer exclusively for advanced users, but are reaching the masses – and this has a direct impact on data traffic.

- 12. Technology trends 12 • 4G LTE is the fastest growing mobile standard ever – Flat network architecture – intelligence at the edge – Smart spectrum management reduces cost and efficiently handle mobile broadband uptake • Software Defined Networks (SDN) and Network Function Virtualization (NFV) is reducing cost and increasing scalability – a distinct move from hardware to software.
- 13. Technology as it impacts satellite 13 • LTE is a flat architecture with an open transmission protocol where end user traffic can be accelerated, optimized and even cached locally • The old truth “coverage is king” still holds true. MNO like low frequency bands and high output power base stations. Macro sites economics beats Small Cells for rural coverage
- 14. Technology trends 14 • 2G is not going away in rural markets! Growth will continue for coverage expansion and GSM still have a place beyond 2020. Biggest device ecosystem and lowest cost to produce a voice call. • LTE is the best solution for data services. • LTE over satellite can achieve terrestrial performance. • 2G for voice and LTE for data is the most cost efficient solution with the best performance when using satellite backhaul.

- 16. Network Topology 16 • Comtech offers solutions for Point-to-Point SCPC as well as Hub- Spoke networks based on HEIGTHS • Point-to-Point examples – Symmetrical services (voice) or when there is little asymmetry – Clustered sites, i.e. microwave backbone to an aggregation point. – Trunking • Hub-Spoke examples – Data centric services where there is a lot of asymmetry or variation in demand • Multi-layer optimization features are available for both topologies for highly efficient and cost effective solutions. No need for any external optimizer for IP based 2G/3G/LTE traffic
