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): Machine-to-machine (M2M) communications are gaining popularity in the mobile cellular networks originally designed for human communications.
In this thesis, measurements from an operator?s network are used to clarify the current state of M2M in terms of traffic and subscriber amounts, 3G utilization rate, radio performance and the popularity of different application groups.

The study reveals that there are big differences in the performance and behavior of different applications.
Currently the most popular M2M application in the examined network is smart metering, while payment is the second biggest.
This conclusion is based on the number of active subscribers and their total amount of transmitted data.
However, the current utilization of M2M found to be still relatively small.
Abstract (fin): Alkujaan ihmisten kommunikaatiotarpeita varten rakennettuja matkapuhelinverkkoja käytetään kasvavissa määrin koneiden kommunikaatioon (Machine-to-machine, M2M).
Tässä työssä tutkitaan matkapuhelinverkosta tehtyjen mittausten avulla M2M-installaatioiden nykytilaa.
Tutkimuksessa tarkastellaan M2M:n kommunikaation liikenne- ja asiakasmääriä, sekä radiolinkin laatuparametrejä ja pyritään ryhmittelemään keskenään samantyyppiset sovellukset.

Tutkimuksessa havaitaan eri M2M-käyttäjäryhmien välillä suuria eroja mm. radiotien laadussa ja liikennemäärissä.
Tämän hetken suosituimmaksi M2M-aplikaatioksi osoittautuvat etäluettavat älykkäät mittarit, sekä toiseksi suosituimmaksi mobiilit maksupäätteet.
M2M-liikenteen ja laitteden määrät havaitaan kuitenkin vielä toistaiseksi pieniksi verkon muuhun käyttöön ja käyttäjien määrään verrattuna.
