The document summarizes Comtech EF Data's Heights Networking Platform for mobile backhaul via satellite. It describes how Heights addresses the rapidly growing demand for mobile data by providing high throughput, spectral efficiency, and intelligent optimization. Heights supports both point-to-point and hub-spoke topologies with dynamic SCPC and advanced LDPC coding. It also offers multiple virtual network operator models and remote gateways supporting varying throughput needs. Key features like Efficiency Boost and VersaFEC-2 coding maximize throughput within minimal bandwidth. Heights provides an optimized solution for cost-effective mobile backhaul as traffic shifts from voice to data-intensive applications.

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.

5. Changing behavior

• Youth… 20% of Latin Americans watch streaming video more
than 3 hours a day.
• Last US presidential debate had more viewers watching it on
YouTube than broadcast television!

Mobile Technology Update

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

38. Summary
• Heights is a 3rd generation platform with CAPEX & OPEX
economics that address the growing "middle market" that
TDMA and traditional SCPC find hard to reach
• Heights provides the horsepower, efficiency and
intelligence required to address your services today and
well into the next decade
• We believe that the middle market will grow significantly,
especially as new HTS birds are launched and end user
demands continue to grow to multi-Mbps to and from
remote sites
