LTE is a World-wide Phenomenon

As of January 2012,

GSA has confirmed

LTE as the fastest

developing

mobile system

technology in

history



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

Considerations in Your Network Planning

Demand for broadband data in your rural coverage areas

Roaming revenue for LTE

Ecosystem maturity

Backhaul Bandwidth Requirements

LTE Increases the Demands on Backhaul

High data rates for eachsubscriber creates higherbandwidth requirementsfor the tower

The amount of bandwidthwill 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

LTE offers RAN sharing through Multi-Operator Core Network (MOCN)

Spectrum can be shared or dedicated per operator

Each operators 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

Motivation and Overall Benefits of Network Sharing

Reduce investments for rollout,densification, or coverage extension

Reduce costs by decreasing OPEXand numbers of low capacity sites

Accelerate rollout enabling fasterservice to a greater population

Provide environmental benefits

with fewer towers and antennas

Regulatory benefits throughfaster time to universal service

Network operators

sharing infrastructure

can continue providingdifferentiated services

and maintaining their

KPIs

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 initiativestay tuned for more information and contact us if you want to participate

Real World Issues andConsiderations

Steve Clark



33/36


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


34/36


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


35/36


The Destination is Clear LTE is the Future

Begin the journey

with confidence,

knowing youre

going in the right

direction

The vendor

community will help

you get around the

obstacles
