so wonderful lecture just one question isn't MGW(media gateway) and GMGW a CS core part?
@Mpirical

That is correct - the CS Core is used by GSM and UMTS for call control, in which you will find MGWs deployed.

Best video ive seen yet about GSM communications. Can you please explain where the PSTN is at in this road map?

The PSTN has been around for a very long time, way before the introduction of GSM. As such, GSM networks use the PSTN to provide connectivity to the fixed line networks, as well as connectivity to other cellular networks.

Wow!!! The content is great!!! Keep up the good work. I have a question: What makes GPRS to have a higher bit rate than GSM even thought GPRS is just an extension of GSM.?
@Mpirical

Great question. GPRS enabled the aggregation / bonding of multiple “GSM timeslots” to increase the total data rate. So effectively, a GPRS user could use the equivalent of up to 8 voice calls (8 GSM timeslots)! In addition, GPRS can use a mechanism called “Adaptive Coding or Coding Schemes” - this adapts the data rate when the radio connection signal (bars on your phone) is stronger. Stronger signal = higher potential rate. It is also worth noting that GPRS has now been enhanced to include EDGE (Enhanced Date for Global Evolution). This included a new radio modulation scheme, which is three times faster than GPRS, that enables more data to be carried. Again, this benefit is more related to when the radio connection signal is stronger.

It is nice but very lengthy and your rate of speech is a bit high. This is just a feedback. Otherwise it is really very informative.
