DESCRIPTION
Indoor solutions as a part of cellular mobile networks’ planning have been used for years in a way to fulfill the lack of an admissible coverage while subscribers experienced using cellular phones indoors. On the other hand, network sharing is a commonly used solution for mobile operators in order to lower their network capital and operational expenditures; that has also commonly been used for Distributed Antenna System (DAS) solutions in indoor deployments. Besides sharing, outsourcing network operation and maintenance has also been widely accepted by wireless carriers all around the world after that IT outsourcing flow, which started in late 90s, seemed to be quite promising for lowering operational costs. The raise of new technologies in this domain that always promise higher, better and more to subscribers, little by little started to become worrisome since operators began to experience lower revenues from voice services during last couple of years as well as higher demand of capacity. As a result, operators started considering deploying indoor networks as a part of their planned network, with regard to the fact that during recent years the femtocell technology became the hot topic for smallcell deployments. This way, MNOs could exploit benefits of covering customers indoors efficiently as well as offloading mobile data traffic from macro cellular networks. But a question rose afterwards; why sharing and outsourcing in smallcell networks have not taken off yet? as they have been commonly used in macro cellular networks and DAS solutions? In this MSc thesis, cooperation between different actors of the shared indoor mobile network ecosystem is studied by investigating both possible sharing models and the concept of outsourcing network operation and management for smallcell networks. This investigation has been done based on femtocells as the most suitable technology both for better coverage and higher capacity. During this process, different roles of actors in the ecosystems, the business relations between them and the main drivers of sharing were studied as well as discussing the main beneficiary of sharing, in order to find different types of cooperation and correlation in the ecosystem. The main research questions in the thesis revolve around absence of sharing either active or passively in indoor mobile networks as well as outsourcing network operation and management. Eventually, a series of possible deployment models for shared and outsourced indoor mobile networks are presented where they have been tried to be verified by a number of use cases. As a result, this study proposes a set of recommendations for different possible operators in the ecosystem in order to formulate a profitable business model for them. These recommendations are believed to enable taking off sharing and outsourcing in smallcell networks.

Indoor network
Most viable options taking Sharing and Outsourcing into account
1) A JV between MNOs deploys and operates the indoor networks.
2) A MNO/JV deploys the network and a third party only handles the network’s O&M regardless of
network deployment.
3) A MSP deploys the network and handles its O&M as well, for either one MNO/JV or more.
4) A MSP deploys its own Smallcell network and makes roaming agreements with MNOs/JVs for
outdoor coverage.
5) An enterprise deploys an indoor network and manages it itself making roaming agreements for
outdoor coverage.
6) The MSP (that is also a NW vendor) deploys the network and also takes care of its O&M offering a
comprehensive system based on Service Layer agreements while making roaming agreements for
outdoor coverage.

Recommendation (Cntd.)
Traditional operators
Type of partnership MNO
JV MVNO Incumbent Greenfield
Rationale Reducing OpEx
mainly by outsourcing
Reducing CapEx mainly by sharing
Reducing CapEx & OpEx
Reducing CapEx & OpEx
Recommended option 2 or 3 3 6 6
Justification
They already have SMP and are not
willing to risk their position by sharing
They have enough financial
credibility to implement their
solo network
Sharing is the origin of JVs so, reducing costs is
a quite convincing
factor
SMP deficit is their reason to
be a virtual operator so,
lowered costs is a KPI
Further recommendation Act as a CS provider
Benefit from CSs and focus more on
core business activities
Outsource as much as possible
Focus on CR and stay flexible
Recommendation (Cntd.)
Third party
Type of partnership MSP Premises
Owner Auth. 3rd party
Rationale Generate new revenue stream
To offer specific services
To obtain added value
Recommended option 6 5 2
Justification
Their philosophy is to partner-up
with other actors and offer CSs
They try to cover a niche market
They are believed to be specialists in O&M that do the
job in an optimized manner
Further recommendation ---
Create a new format of model 6 and benefit from
CSs
---
Smallcell Repeater
� Adds both coverage and capacity, with ability to
improve data rates
� Generates its own signal
� Reduces uplink interference by removing handsets
from outdoor network
� Provides full control of handover
� Fault and performance monitoring and full O&M
support
� Generates operator-specific signal
� Requires broadband IP connection to connect back
into network
� Can feed a DAS system
� Only extends coverage, no additional capacity (feeds
off macro network)
� Requires donor antenna which can be expensive to
install on roof
� The repeater itself can cause uplink interference
creating radio planning problems
� Handover neighbors same as the macrocell
� Most repeaters are unmanaged with no automated
fault reporting
� Cheap repeaters amplify competitors’ signals
� Works in isolation, but needs nearby macro site
� Can feed a DAS system
