Transmission Timing in WCDMA terminals
Power control is one of the technologies used to utilize the radio resources as efficient as possible in WCDMA. The transmission power is adjusted to transmit with the lowest power level possible while the required received signal quality is maintained. Since there are large variation in channel quality over time, the power has to be [...]
Mobile payment with customer controlled connection – Can it be constructed to be safe enough?
The mobile commerce has given birth to many mobile payment systems and this thesis covers the security of a theoretical system where the communication is handled by the customer. There are many technologies that can be used when implementing such a system, each with different strengths and weaknesses. The system designed in this project was [...]
Achieving Security in Messaging and Personal Content in Symbian Phones
This thesis describes two proposed schemes that could be used to secure mobile messaging (SMS/MMS) as well as one scheme that could be used to secure mobile content. The security services we considered in securing the mobile messages are confidentiality, authentication, non-repudiation and integrity. We used Identity Based Cryptography in order to secure the mobile [...]
TCP performance in an EGPRS system
TCP (Transmission Control Protocol) is the most important transport level protocol used on the Internet today. When the Internet is moving towards more use in mobile applications it is getting more important to know how TCP works for this purpose. One of the technologies used for mobile Internet is the Enhanced General Packet Radio Service [...]
Security in Unlicensed Mobile Access
Unlicensed Mobile Access (UMA) provides transparent access to 2G and 3G networks for Mobile Stations over the unlicensed radio interface. Unlicensed radio tehnologies such as Bluetooth or WLAN technology connects the Mobile Station to the fixed IP network of the home or office and delivers high bandwith to the Mobile Station.The purpose of this report [...]
