Today the cloud services are parts of our every day life. We use cloud services for emailing, chatting, storing data, watching videos, listening to music and editing documents. We can access these services from our desktop computer, from our laptop, from our tablet or from our smart phone too independently from what kind of technology (wired or wireless) do we use to connect to the internet.

An earlier technology, similar to cloud services is the thin client architecture. The cloud equivalent of the thin client service is called Desktop-as-a-Service (DaaS), which is like we have a personal computer in the cloud.

In my thesis I search the answer for the questions: How well a DaaS can be used through mobile data connections (HSPA and LTE)? What are the requirements of a system, which is accessible from anywhere, so it's mobile and which serves the functions of a personal computer through SaaS? Can we satisfy these requirements with currently available solutions?

To find out the answer I planned and implemented a system which can provide DaaS with different available solutions. I made speed and latency measurements on 3G and 4G mobile data network and also created a user activity model for the tests. I have tested 4 available solutions through HSPA and LTE connections and I monitored and documented the used bandwidth and the user experience.
