11 PROPRIETARY AND CONFIDENTIAL
LTE is a World-wide Phenomenon
As of January 2012,
GSA has confirmed
LTE as the fastest
developing
mobile system
technology in
history
12 PROPRIETARY AND CONFIDENTIAL
LTE Improves Performance in Multiple Ways
Higher Peak Data Rate: Instantaneous
data rate of 150Mbps for downlink and
50Mbps for uplink in 20MHz
Higher Spectrum Efficiency: 3-4 times of
HSDPA, 2-3 times of HSUPA
Flexible Spectrum Allocation: Scalable
channel bandwidth, supports both FD&TD
Better User Experience: High speeds plus
lower latency, < 5ms in ideal conditions
LTE Performance Improvements
OFDM Modulation 64QAM
LTE Air Link Improvements
State-of-the-art modulation techniques
MIMO
Multiple antennas
create multiple input
and output channels

RAN
• All IP network
• Flatten architecture
• Less network element nodes than 3G
• Higher capacity, better scalability
• Control plane intelligence
• Policy and charging control
• Open packet core, supporting all access technology
17 PROPRIETARY AND CONFIDENTIAL
• MME – Signaling control, bearer and connection management
• P-GW – IP assignment, connection to internet
• S-GW – Mobility and idle state management, lawful intercept
• HSS – Subscriber data, authentication, QoS profile, access restriction
• PCRF – Policy decision making, QoS authorization

BENEFITS
• Significant
reduction in
capital costs
• Faster time to
market
• Simplifies
ongoing
operation
• Can be
migrated to an
in-network EPC

Backhaul Bandwidth Requirements
LTE Increases the Demands on Backhaul
High data rates for each subscriber creates higherbandwidth requirements for the tower
The amount of bandwidth will depend usage profiles
– Voice over LTE will
require high QoS
– Browsing and other data
traffic is more forgiving

Your Launch Plan Must Align with Device Availability
USB dongles, fixed wireless home gateways and MiFis will
be the first to appear
Sophisticated handsets need the buying power of large
carriers in a coordinated strategy with the regional carriers

* Verizon also has significant holdings of 700 Lower A&B
* * AT&T also now own significant AWS bandwidth but no announcements regarding LTE
Metro PCS is driving LTE device availability on AWS bands

Operator A
• LTE offers RAN sharing through Multi-Operator Core Network (MOCN)
• Spectrum can be shared or dedicated per operator
• Each operator’s EPC is connected to the shared RAN
• Each operator may have dedicated 3G RANs (e.g. CDMA) in addition to
the shared LTE RAN
Classic Configuration Shared RAN Configuration
30 PROPRIETARY AND CONFIDENTIAL
Motivation and Overall Benefits of Network Sharing
Reduce investments for rollout,
densification, or coverage extension
Reduce costs by decreasing OPEX
and numbers of “low capacity” sites
Accelerate rollout enabling faster
service to a greater population
Provide environmental benefitswith fewer towers and antennas
Regulatory benefits through
faster time to universal service
Network operators
sharing infrastructure
can continue providing
differentiated services
and maintaining their
KPIs
31 PROPRIETARY AND CONFIDENTIAL
The LTE Open Ecosystem initiative has
four goals - if achieved they would assure
the viability of 4G in rural America
1. Fair and equitable roaming
2. Access to the latest devices
3. Access to spectrum leases to
combine with existing holdings
4. Radio network sharing through
MOCN
Toward an LTE Open Ecosystem – A Wish List
RCA, ClearSky and others are working on the Open Ecosystem initiative –stay tuned for more information and contact us if you want to participate

33 PROPRIETARY AND CONFIDENTIAL
Considerations For LTE Deployment
New RF design for integration
MIMO vs. current antenna configurations
Coax vs. fiber cable and RRU
Review existing site leases
Backhaul microwave vs. fiber
IP address administration & security
Billing & provisioning with new HSS
Review disaster avoidance & recovery
34 PROPRIETARY AND CONFIDENTIAL
Summary
New network with many of the same processes
All IP data – voice is an app on the network
New focus on RF design, backhaul, and IP security
There is much to do but all of it is reasonable and can be done
35 PROPRIETARY AND CONFIDENTIAL
The Destination is Clear – LTE is the Future
Begin the journey
with confidence,
knowing you’re
going in the right
direction
The vendor
community will help
you get around the
obstacles
