Some of the main projects I was involved :

• Oct 12 - Jan13 Meditel-Morocco

Analysing and modelling the various complex topologies of current 2G/3G networks' architecture (multiple paths from single BTS/NB to the parent BSC/RNC, loops or rings, Drop/Inserts chains) with the use of advanced multi-layers NEP model which enables the support of such complex configurations.

Dimensioning of GSM/UMTS transmission networks (PDH/SDH and ATM technologies) and identifying Bottlenecks, replacing or upgrading congested links with detailed reports of changes done.

Making the connectivity of the Fiber Optic for all the Morocco region according to the TAB file.
making presentation for Meditel’s engineers to let them know how use our tool and Got the final acceptance for the project.


• Jul 12 -Sep 12 cote d'ivoire-Africa

Optimize the switching Core Network routing for efficient usage of available transmission bandwidth and spare capacity utilization, providing alternative routes for affected traffic in a link(s)/node(s) failure/congestion scenarios; detect infinite loops in routing tables.
Making the route of the BTSs till the parent BSC according to the Dump files.




• Apr 12 -May 12 Alfa - Lebanon

making the configuration and the connectivity of the DDF according to Alfa’s input files.Analysing and modelling the various complex topologies of current 2G/3G networks' architecture (multiple paths from single BTS/NB to the parent BSC/RNC, loops or rings, Drop/Inserts chains) with the use of advanced multi-layers NEP model which enables the support of such complex configurations.
