LTE


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

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


• 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


Considerations in Your Network Planning

Demand for broadband data in your rural coverage areas

Roaming revenue for LTE

Ecosystem maturity

Cost and network scalability

Timing for LTE build-outs

Deployment strategy (migration to LTE)

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


The Device and Roaming

Ecosystems

Dean Fresonke



The Outside Ecosystem is a Big Part of Your

Network Planning

Licenses held and

licenses available

for lease

Most issues go away if you are planning a fixed wireless broadband launch

…700 MHz Has Band Plan Barriers


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

Metro PCS is driving LTE device availability on AWS bands

LightSquared or Clearwire may someday be nationwide roaming options


A Step Beyond Roaming – LTE Enables RAN Sharing

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


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


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


Real World Issues and

Considerations

Steve Clark



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


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


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
