In the last few years, there have been significant changes to how telephony services are provided driven by the convergence of telephony and data communications. The use of voice over IP gives greater flexibility for users and reduced costs for both providers and users.
The PTT’s online course “Telephony and data services” gives a comprehensive overview of how communications services are provided, and the facilities available to residential and business users
A new module of the course covers the provision of telephony for businesses with emphasis on IP telephony and Internet telephony service provision.
This “Telephony and data services” course, which is aimed at communications technicians and managers, is suitable for use in digital apprenticeships.

It has historically taken about 20 years for each mobile generation to reach its peak usage while a new generation has been introduced on average every 10 years.

This means some areas are served by several generations of mobile system from 2G through to 5G.

Therefore, mobile system technicians need an appreciation of the operation and features of all current generations.

Also, understanding how mobile systems have evolved towards the latest 5G systems gives a deeper insight into how maximum capacity and speeds are achieved in cellular networks.

This is the approach taken in the PTT course “Introduction to mobile systems” and its new companion course “Mobile radio communications“.

The high speeds and low latency offered by 5G has been in the news recently with the launch of the first 5G mobile services in the UK. The improvements offered by 5G have been built on years of technological development as mobile systems have evolved.

PTT updated online course “Introduction to mobile systems” provides an overview of mobile communications and reveals how mobile systems have evolved to meet users’ expectations for high speed access to online services while on the move.

The course is suitable for those joining the mobile sector in a technical role and for experienced engineers who want a refresher to update their knowledge of the systems they work with.
