Evolution of Mobile Networks - Impact and Possibilities for Future Services
This presentation discusses the evolution of mobile networks and the resulting potential for future devices and applications. Drivers are, for example, LTE, HSPA+, higher speeds, more bandwidth, fixed-mobile convergence, DSL and cable access in an overall network strategy, cloud computing, connected home services, always best connected, social networks and privacy.

Future Services By Whom?
Internet based companies (Google, Skype,
•
Yahoo, startups, etc.)
Their business model: Idea, trial and error, free at
•
the beginning, later funded by advertising and
premium services
Network Operators
•
Their business model: Pay for services from day
•
one → Interop. and getting a critical mass is difficult
This presentation looks at how Network Operators
can benefit from the Network Evolution

Trend 1: Wireless Networks Are
Evolving
UMTS → HSPA → HSPA+
•
LTE is at the doorstep, promises even higher speeds
•
Lots of improvements to achieve higher speeds like
•
higher order modulation and MIMO.
Digital Dividend for Broadband Everywhere
•
The good news: Higher top speeds will help us for
•
some time to escape bandwidth bottlenecks.
The bad news: Super high speeds only in selected
•
places!

Higher Speeds But Not Everywhere

Cellular Capacity Today and
Tomorrow
3G Network Capacity Today: ~30 MBit/s per km²
•
(4 UMTS networks, one BTS per operator per km², 3 sectors, single carrier)
Based on 70 MB of daily data traffic (~2 GB/month) that's
•
good for 800 users per km²
Potential 3G Capacity Tomorrow: ~ 500 MBit/s per km²
•
(use of full capacity in 900, 1800, 2100 and 2600 Mhz with HSPA and LTE)
→ But: Who can predict how many people will use the
system in the future and how traffic develops?

Trend 2: Fixed Line Advances
ADSL speeds are increasing
•
ADSL2+ available in many
•
locations
VDSL now being deployed:
•
But: Expensive!
Fiber to the Home
•
→ Almost infinite capacity and A VDSL cabinet
reachability.
But: Even more expensive!
And on top: It's fixed line but most people don't use it with
a cable → Wi-Fi is also wireless!

Trend 3: Fixed – Wireless
Reintegration
Wireless Operators are buying fixed line assets
•
again.
With the Internet, operators have finally
•
understood that it makes no sense anymore to
offer fixed and mobile services separately as
most users want both! → Usability break!
Complete reversal over earlier trend!
•

Trend 4: Femtocells - Making use
of Fixed Line Assets
Femtos will be integrated
•
into a single DSL-modem /
Wi-Fi / Picocell package.
The first obvious use: It's
•
good for offloading a
significant amount of traffic
from the macro network.

Putting all 4 Trends together leads
to: Connected Home Services
„Mobile“ devices (phones, smartphones, mp3
•
players, cameras) interact with the „fixed“ devices in
the home network (PC, Network Attached Storage
containing pictures, videos, and other private
information)
Access to „fixed devices“ and data stored on them
•
also while being outside the home network via the
cellular network over an encrypted link.

Connected Home Services
Femtos vs. Wi-Fi
Femtos great for network operators
•
Wi-Fi great for Internet companies
•
Who will win?
•
Maybe both should win?
•
Peaceful coexistence.
•
Always best connected (best as in fastest, cheapest,
•
most convenient). Possible with both femtos and
Wi-Fi. → Intelligent Software

Trend 5: Cloud Computing
What is it, who likes it and why? → Computing resources
•
in the network and storing data (calendar, address book,
files, etc.) somewhere in the Internet.
Many interesting possibilities, BUT: storing private data
•
on the Internet is not to everyone's liking → inherent
privacy and security issues, wanted and unwanted.
→ Connected Home Networks offer an alternative
to storage in the cloud to protect data and privacy!

Summary
Trend 1: Wireless Network Evolution
•
Trend 2: Fixed Network Evolution
•
Trend 3: Fixed - Wireless Re-Integration
•
Trend 4: Femtos + Wi-Fi
•
→ These trends pave the way for Connected Home Services
Trend 5: Cloud Computing
•
Anti-Trend 5: From the Cloud to the Home
•
→ Great possibilities for network operators in the future!
