Current Projects 

Assessment of Capacity and Performance Enhancement using Frequency Hopping on STC GSM Network 

(National Research Project, 490,000 RS) 2005  

(KSU, Network operators, with their limited frequency resources, must offer the required capacity on the one hand but on the other hand they must also keep their investment in network infrastructure under control. SFH improves performance and capacity through frequency diversity (FD) and interference diversity (ID), respectively. Detailed investigations concerning the FH system configuration are required, especially in wide band FH (more frequencies to hop over than the needed number of TRXs to serve the given traffic.

This project aims at determining under which conditions and in which network configurations maximal gains can be achieved. We plan to estimate the gain by using analysis, simulating SFH on computers, and validating the results with field tests.   

Mobile Phone Base Station Radiation Safety

 (CITC, 1.8 million Riyals) 2006

The project’s aim is to undertake an audit program measuring emissions from mobile phone base stations to ensure they do not exceed guideline levels, at each operational, externally sited base station in the city of Riyadh and information specific to each of these base stations.

The project execution is alongside with the “precautionary measures” adopted by most of the European countries, the USA, Canada, Australia, etc. for the protection of its citizens from potential health hazards resulting from exposure to EM radiations from mobile phone and base station antennas.
