LTE trials show progress in both emerging and developed regions

The largest number of LTE network trials

are in Central and Eastern Europe

(CEE– 26), Emerging Asia–Pacific

(EMAP–24) and Western Europe (20).

Trials in CEE and EMAP in particular

are driven by the adoption of the

technology by regional operators such

as Bharti Airtel, China Mobile, Reliance

Infotel and SoftBank.

Infrastructure vendors including

Huawei, Ericsson, NSN, Samsung and

ZTE demonstrate network upgrade and

transition options.

Conclusions



When implementing an LTE network, mobile network operators have two key deployment strategy choices …

As demonstrated in the first part of the presentation, LTE is becoming the

technology of choice to provide mobile broadband.

Before deploying LTE, operators have to formulate a commercial and technical

strategy that aims to maximise revenue and minimise costs as well as meeting

subscribers’ performance expectations.

Typically, an established mobile operator has multiple access networks (for

example, 2G and 3G) and needs to take a holistic view of its legacy multi-

technology network to exploit all synergies to identify the optimum LTE

deployment solution.

There are two key network strategies to consider when introducing LTE:

LTE overlay

single radio access network (SRAN).

13



… LTE overlay or single RAN

14

An LTE overlay requires deploying a

separate LTE radio access network

(RAN) in addition to any legacy 2G

and 3G RAN and core networks.

An SRAN strategy involves installing

a single base station unit that

provides both the functionality of a

new LTE base station and replaces

legacy 2G and 3G base stations.

SRAN is rapidly becoming the

norm – for example, 51% of

Vodafone’s European sites have

already been upgraded to SRAN

(as of March 2013), increasing to

80% of the sites by 2015.1

Single RAN deployment



The life-cycle of the 2G network plays an important part in determining the optimum LTE deployment strategy

15

Many legacy 2G RANs are at

end-of-life and vendors no longer

support them commercially.

Maintaining a legacy 2G RAN

involves a tailored vendor

maintenance contract, which can be

very expensive.

Operators typically hold spares stock

for legacy 2G networks, but these

become depleted over time.

Additional spare parts are available

on the grey market, but the quality

and volumes cannot be assured.

Reasons why 2G will still exist for several years

Terminal is affordable

Is well-suited to low-end users

Is required to support roamers

Is well-suited to M2M applications

In Europe, the GSM switch-off will

occur between 2019 and 2025,

depending on country and operator

strategy, for the reasons cited above.

However, there is a requirement to

extend the lifetime of 2G networks

to provide voice service support

for LTE networks.

Is well-suited for voice services



The benefits of LTE overlay versus SRAN are well documented, but there is little regarding cost implications

LTE overlay Single RAN

Operational benefits

Fast time to market

Low network disruption

Single access network to manage

Cell site simplification

2G and 3G life extended

Technology flexibility

Operational challenges

Multiple access network to manage

Single vendor dependence

Significant implementation risk

Cost benefits Lower capex? Lower opex?

Analysys Mason has developed TCO models to quantify the capex and opex

associated with each solution.







Conclusions



We consider three different scenarios to compare the TCO of LTE overlay versus Single RAN deployment

A European incumbent fixed and mobile operator with significant 2G, 3G and fixed

broadband coverage needed to understand the TCO associated with different

LTE deployment strategies in order to make an informed investment decision.

To compare the TCO associated with different LTE deployment strategies, we

considered three different LTE deployment scenarios.

We analyse the capex and opex associated with both new LTE networks and existing 2G/3G networks

Core equipment LTE network vendor maintenance

Backhaul network Existing infrastructure running costs

(such as power, site rental and

operational personnel)

Support services (such as installation,

optimisation and so on)

Incremental infrastructure running costs

(such as power, site rental and

operational personnel)

Cost of change (such as additional staff

required for implementation of LTE)

Other opex



The capex associated with an SRAN is lower than an equivalent solution that requires a new 2G network …

20

Capex associated with:

scenario 1 is 40% higher than the

base case because of the refresh

of the 2G RAN network.

scenario 2 is 31% higher than the

base case because of the refresh

of 2G and 3G RANs as well as the

replacement of 2G/3G core network.

Deploying a 3G network using an

SRAN solution is very cost effective.

Installation and integration services

associated with single RAN solution

are less expensive than service

associated with LTE overlay solution

because less integration is required.

21

Opex associated with scenario 2 is

32% lower than for scenario 1, and

28% lower than for the base case.

Main opex savings are associated

with vendor maintenance contracts.

More cost-effective to have a single

maintenance contract for an SRAN.

SRAN removes the requirement for

premium-priced legacy 2G and 3G

maintenance contracts.

Second opex saving: support staff.

Fewer staff needed to operate and

maintain an SRAN than individual

2G, 3G and LTE networks.

22

TCO for scenario 2 is 21% lower

than that for scenario 1, and 10%

lower than base case.

Opex savings offset additional

capex required to deploy the new

2G and 3G networks over 5 years.

Opex savings for the SRAN are

mainly driven by:

single rather than multiple

maintenance contracts

no need for premium-priced

support of end-of-life equipment

reduction in the number of

support staff.

Conclusions



Conclusion

The regional influence on the LTE ecosystem will change during the next 5 years

as Emerging Asia–Pacific countries build their LTE networks.

LTE is the technology of choice for multi-spectrum networks.

VoLTE will continue to lag during the next 5 years, making LTE a technology

suitable to primarily deliver data services.

In terms of deployment strategy, the SRAN solution attracts the lowest TCO

compared with LTE overlay network for the considered case study.

However, for cost savings to materialise, SRAN solutions have to be implemented

in a ‘big bang’ approach, which can be challenging for operational teams.

Each operator will have a unique starting point in terms of market

conditions and cost base that may dictate a different LTE strategy.
