Serving the next generation customers, extending the

demarcation

The Challenge (Cisco VNI Mobile Traffic Feb. 2017)

• MEA mobile data traffic grew 96% in 2016 and will grow 12-fold until 2021, surpassing NAM traffic”

• LTE devices carried 69% of all mobile traffic in 2016 and will surpass 2G & 3G connected devices in 2017

• 87% of all handsets will be smartphones in 2021

• Smartphones will carry 52% of IP traffic in 2021

• Fixed (Desktop) IP traffic is today less than 50%

What does these figures mean?

• Wireless (WiFi & LTE) is the standard for Broadband connectivity

• Smartphone will be the Internet terminal of choice for personal and business usage

• Be prepare to scale exponentially: traffic x 12 next 5 years• Number of users x 4

• Average traffic per user x 3: MEA from 3.8 Mb/s average per handset today up to 10.8 Mb/s per handset in 2021

• Evolving from Broadband (1 Mb/s DL) to Ultra-BB (10-20 Mb/s DL)

• Is the solution still individual satellite access point ending at the ethernet port?

What is the impact on delivering satellite services?

LTE/WiFiTerminal

• Or is it rather shared access through Hybrid LTE satellite backhaul ending within the users device?

And consider, where (and what) is the demarcation point?

From

To

An equipment uptime & link availability model

A User Experience and application behavior model

Aspects that count.

• Spectrum efficiency (OPEX)Aggregation and sharing of last mile bandwidth through LTE enables more efficient satellite backhaul solution

• Maintenance and Operation

Aggregated sites results in fewer large vs many dedicated Single, reducing the operational field expenses, enhancing reliability and performance

• Integrated Application Optimisation Users expect “terrestrial-like” service in terms of speed (bandwidth) and response time (web browsing) for content delivery, less tolerant to contentionQoE is the driver for successful service delivery today

• Coverage & Availability:

Service Anytime, Everywhere. Ability to access information indoor at home or office

(fixed) and on the move (outdoor) with the same device
