Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Recent advancement in System Architecture Evolution (SAE) has opened the door for the deployment of femtocells on a large scale.
Deployment of femtocells in the existing macrocell networks and in 4G networks will significantly increase because femtocell offers increase coverage and capacity in both home and office environments.
Hence it is likely that these low-power home based access points are going to change the landscape of mobile technology and the networking business in the coming years.
This thesis work offers a deep insight into the mobile communication system architecture evolution and typically explains femtocellular aspects in the evolution of Universal Mobile Telecommunication System (UMTS) architecture.

This research work mainly focuses on architectural variations of 3G and 4G femtocells along with the operational functionality of Local IP Access (LIPA).
LIPA introduces the functionality in femtocells to access a home Local Area Network (LAN) and enable customers to use the Internet through Internet-enabled devices.
Hence users have the capability to have simultaneous access to the operator's network as well as having access to their own home LAN.
The way LIPA works is explained How it can create problems for femtocells deployment and what solutions LIPA offers for providing easy femtocell configurations.
With the help of the extensive study about LIPA-enabled femtocells, different scenarios are discussed and two different solutions are proposed both for 3G and 4G femtocells.

For maintaining higher data rates, 3G and 4G systems require a good coverage area to increase system performance.
But research results suggest that two-thirds of consumers suffer from inadequate indoor signal penetration which actually leads to poor coverage for consumers, who do not enjoy the full data capacity as guaranteed. 4G systems will facilitate high speed data services, but poor coverage and interference will definitely diminish the quality of real-time applications and will significantly slow down high speed data services.
The aim of this thesis is to propose di_erent logical indoor 4G femtocell architectures based on 3GPP specifications that will also be capable of providing LIPA functionality.
