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.?
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.

Damn....what an underrated channel man....all concepts are clear
This video is everything I’ve been looking for
One of the best videos I've been looking for.. thanks..so informative
Very clear and concise!
so clear and concise, thank you
Superb!
so wonderful lecture just one question isn't MGW(media gateway) and GMGW a CS core part?
That is correct - the CS Core is used by GSM and UMTS for call control, in which you will find MGWs deployed.
The best explained video 👍.
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.
Clear explanation..
Thank you
Grreat explanation. Any idea what 'Um' means/represents for the air interface? Looked everywhere but can't find it.
Wow!!! The content is great!!! Keep up the good work.

The content and explanation is good. But the ads about your videos is very disturbing.
Very nice and elaborate, a big thank you.
I recently switched my sim card in my device and now my device is acting like someone else owns it through your site what can I do.
plz do a lec series on dsp
Wow you are awesome
Very thanks
Simply explained
Now we need the IMS
very nicely explained
Really informative...!!
Amazing
best
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.
HaHa, ideas in 1:59 has become true
lol, just why *are* they disguised as trees...?
