Initial discussion with Orange NL started in mid-2001.

JV operational from mid 2002 to 2004.- Site & ancillary sharing.

- Common plan & build organization.

- No common procurement.

JV closed down in YE 2004.- Staff resistance (them vs us)

- Different strategic objectives.

- TMNL decides no need for ancillary sharing.

- More economical to share own infrastructure than common.

Oct 2007 T-Mobile acquire Orange; network consolidation started.

Nov 2008 all Orange customers were migrated to T-Mobile’s radio network

T-Mobile US – Cingular – The GSM Factory.

Geographical GSM RAN sharing agreement.

T-Mobile US (via JV) responsible for NYC Metro areas. Population ca. 22+M #Base Stations ca. 2,300 (at time of breakup).

Cingular (via JV) responsible for California/Nevada areas. Population ca. 40+M (TMUS had 1.7M subs @ breakup in CA/NV) #Base Stations ca. 5,000 (at time of breakup).

Venture discontinued in 2004 with Cingular – AT&T Wireless merger. TMUS pays (net) $2.3B for California/Nevada + add spectrum optionality. TMUS forced to spin-off 10MHz in NYC Metro markets (very painful!). Nationwide roaming agreement.

Deutsche Telekom sharing examples (1 of 4).

Dr. Kim Kyllesbech Larsen, Technology Economics – Deutsche Telecom

T-Mobile– Orange NL merger… 2008 – 2009.

Price of Orange NL was ca. €1.3B or ca. €600 per customer.

One single network by 2010 with

- Ca. 5,000 fewer radio nodes and

- Ca.3,300 (ca. 50%) fewer site locations.

Securing future competitive growth.

leveraging on higher spectral efficiency by consolidating.

On track to deliver synergies in excess of €1+B by 2013 (in time & money).


2008 Acquisition.

TMUK – H3G 3G RAN sharing – more for less.2007: Joint venture design, plan & build-co MBNL Ltd.

TMUK adds 3,000 – 5,000 3G Node-Bs that would otherwise not have been financially/economical feasible.

Common 3G plan & build organization (MBNL Ltd).

Positive TMUK EBITDA net of £50m (ca. 4% “run-rate” avoidance).

– H3G benefits from faster and much more efficient deployment .

Positive annual Capex benefit of £79m by 2012 (18% “run-rate” avoidance).

– H3G capital benefits far in excess of £0.5B (estimated saving & avoidance).

Substantial site lease cost savings and cash prevention expected.

– From 2011 and onwards.


T-Mobile– Orange UK Network JV.

1 single network by 2014ish with 30%-40% denser grid than standalone.

- Starting point a network of 14,000 sites, today the end-game is 18,500.

Total 9,000 site locations will be terminated (33% reduction)

Leveraging higher spectral efficiency by consolidation.

Large and readily achievable synergies in both Network & IT.

Significant synergies with NPV in excess of £3.5 bn.

- Opex run-rate synergies ca. 35% (on relevant cost!)

- Capex “run-rate” synergies up-to 25%.

Integration & termination cost of up-to £1.2 bn.

EE has the BIGGEST mobile network(s) in UK which will remain so even after consolidation and integration has been finalized.

Vodafone sharing examples.



Vodafone – Orange sharing … 2007.

Rural Area / Geographical sharing.

National roaming like sharing concept with joint field services.

Rural areas with population of less than 25,000 pops.

Ca. 1,500 Node-Bs where shared by YE2007 with max 5,000 by YE2009.

Venture frozen in 2009 as VF announced sharing deal with Telefonica.

Network sharing agreement in Spain and Romania.

(i.e., VF-Europe Opex in 2008 was £16.4 bn and TF-Europe 2008 Opex was in the order of £13 bn).Kim Kyllesbech Larsen, Technology - T-Mobile. 19

Vodafone – Telefonica sharing … 2008.

Passive RAN network site sharing.

Traffic managed independently of each other.

Customers expected to benefit from improved coverage.

Benefits in the order of ”hundreds of million” £ for both over next 10 years.

Today (May 2012) they share 4,000 site locations.

Network sharing agreements for Germany, Ireland and the UKwith detailed discussions ongoing in the Czech Republic.

(i.e., VF-Europe Opex in 2008 was £16.4 bn and TF-Europe 2008 Opex was in the order of £13 bn).

Vodafone – Telefonica sharing … 2012.

Passive sharing including backhaul.

Common Build JV, planning & design separately.

1 single network by 2015 with doubling the site count to standalone.

- Each has ca. 10,300 sites today with shared end-game of 18,500.

Total of ca. 2,000+ site locations will be terminated (10% reduction).

Geographical (50%-50%) sharing (i.e., London halved).

No Frequency sharing.

Individual supplier relationships (missing out on procurement scale?).

Massive Opex and Capex avoidance.

This is NOT an Opex reduction game but rather matching EE super-grid.

Getting a lot more for less …. Capex & Opex avoidance.


The Good and The Ugly.Recipe for successful merger (or network sharing) and is matching technology landscape and strategic outlook. Matching spectrum position and network grid are much more valuable (short-term) for synergies than complementary spectrum.

Sprint - NextelAT&T – Cingular merger

Matching technology landscape and strategic outlook.

Good complementary spectrum (high grid match).

Fairly symmetric & matching business structures and models.

Mismatch in technology landscape & strategic outlook.

Complementary spectrum but relative low grid match.

Very different business structures and models.

Restructure cost can be significant. Although contract termination can be less costly due to longer operational period.

Termination• Site lease.• Site restoration.• Service

Contracts.• Personnel cost

Other• JV overhead• Legal, etc..

Restructuring cost can be low if little legacy infrastructure is present.

If decision for network sharing is taken in the renewal / obsolescence phase write-off exposure can be relative light both for equipment and site-build.

As most of the network has been deployed at this stage the write-off exposure can be significant even if equipment can be re-used.

Relative low exposure if little legacy infrastructure is present.

Economics of RAN sharing benefits.

Anatomy of network sharing.RAN sharing guaranties competitive differentiation, operator independency and vast consumer quality improvements.

• Sharing: Costly Radio Access Network infrastructure will be shared,

• Not shared: All core network and service infrastructures that provides respective customers with differentiated services, applications, handsets, rate plans, etc.

• Result: A network with greater capacity (i.e., instant cell split) and improved coverage.


Network Sharing Strategies

Network sharing.A mean to close the mobile broadband coverage gap (in CEE).

3GPP Release 8, 2009 (earliest) onwards with the following sharing concepts:

Gateway Core Network (GWCN) shared core network (CN) (multiple CNs connected to a common core, connected to the shared RAN).

MOCN: Multi-Operator Core Network where only the RAN is shared (i.e., NO common CN).

Introduction of Iu Flex allowing multiple CNs connecting to shared RAN.

Multiple core networks connected to a common radio access network (RAN) sharing a single frequency or a pool of frequencies.

Service requirements & capabilities not limited by the sharing requirements (i.e., resides in core network or service creation platforms above the core network).

Requires user equipment support (i.e., R8 or later). Non-supporting user equipment will ignore the broadcast system

information related to sharing functionality. Fairly complex coordination issues on resource allocation among

sharing parties, making this concept more interesting for low-traffic rural areas (where demand is no issue) or highly asymmetric traffic situations.
