Course Details

This course builds on the GSM and GPRS System Engineering course and thereby focuses on the specifics associated with the air interface when supporting packet data transfer. This includes detailed analysis of the logical channels, multiframes and protocols before explaining packet data procedures from a radio perspective. EDGE and Evolved EDGE is also discussed in terms of their associated enhancements and feature sets. Finally, the course evaluates the enhancements that have been made to support IoT applications through the introduction of EC-GSM-IoT.

Frequently Asked Questions

Will I receive certification for completing the course?

Yes, all our courses provide a shareable certificate of completion following the test of understanding.

How long do I get access to the course?

On-demand courses are accessible immediately following purchase. Each course will have a different access period ranging from 3-6 months on average. You can continue to access the Mpirical learning platform after your course licence expires; however, you won’t be able to view any course content or learning tools unless you are a paid customer.

What else do I get with a course?

All students benefit from automatic access to our ‘Ask the Trainer’ feature with an on-demand course purchase. You will also get access to our acclaimed network visualisation tool, NetX.*

*NetX is not included with the Mini Telecoms MBA course or partner training.

Can I access the course offline?

Offline access is not currently available. You must use a connected device to access the course and learning tools. However, course pdfs and reference documents are downloadable.

Is there recommended follow-on training?

Yes, we do recommend follow-on training courses within the Mpirical learning platform.

How do I choose between a live course or on-demand course?

Our live courses are generally reserved for teams and enterprises of 10 or more. If you’d like to learn more about purchasing a single course to be delivered at your location or online, please get in touch: enquiries@mpirical.com.
