“THE FUNDAMENTALS OF 2G MOBILE COMMUNICATION SYSTEM” SERIES

Category: 2013 , Seminars

Thursday 14th of February, 2013 witnessed the beginning of IEEE Alexandria Student Branch’s (IEEE AlexSB) Mobile Communication Track (series of seminars), hosting Mr. Khaled Yousry Khalifa –senior engineer at Alcatel Lucent– to introduce the audience to the field of mobile communications, mobile systems, and mobile networks.

The target of that session was to discuss what the mobile communication market needs, what the career choices are, and how to be ready for them. Then, Mr. Khaled gave a tip about how to save almost 3-4 years from one’s professional career by working on some easy, yet important skills and points, like setting targets and soft skills improvements.

After that, he spoke about market opportunities and emphasized on the importance of hunting opportunities and not just waiting for them to turn up. Then, he discussed some of the technical requirements for entering this market, such as being strong in MATLAB, Oracle, Java and UNIX. He then finalized his talk by giving some hints to help the students from the audience in writing their CV’s, from which were: Don’t put your personal photo in the CV; Use a formal E-mail; Never put your friends as references, you may choose a senior, or someone you closely worked with or anyone you have worked with in a project; Be specific in your objective; The CV should be a maximum of two pages.

Later on Saturday 23rd of February, 2013, IEEE Alexandria Student Branch (IEEE AlexSB) hosted Mr. Khaled Yousry Khalifa –senior engineer at Alcatel Lucent– in the second session of a series of seminars about mobile communication.

The session started with a description of GSM history which evolved from the first generation to the third generation of mobile systems. After that, Mr. Khaled explained more about GSM and the differences between uplinks and downlinks. The network is determined by the number of users, the limit of GSM systems depend on coverage. He added that there are three types of GSM systems: small, medium, and large. In GSM900 there is an extended bandwidth from 25MHZ to 35MHZ which means that the network can support extra users. Then he explained how if the frequency increases, the bandwidth increases so that the network can cover a large number of users. He continued explaining that any communication system works on two standard points, Standard: IEEE (IP, DN) and Wireless: 3GPP (2G, 3G, LTE). Moreover, the speaker talked about antennas which are classified in general into two types: Omni directional antennas and unidirectional antennas. The speaker finalized his talk by explaining how to plan the mobile network layout and how to arrange network cells, in addition to explaining Time division Multiplexing.
