DAMM webinar series hosted by Utilities Technology Council (UTC)
30/03/21 11 AM ET
The webinar gives a practical approach to modelling telecommunication traffic with focus on group communication. The session explains properties of the exponential distribution which is basis for Erlang formulas. Both, blocking and queuing systems will be considered in the calculation examples.
Aim of the webinar is to have a clear understanding of the basics of telecommunication traffic theory and be able to dimension simple networks for both individual and group communication.

The webinar gives a practical approach to modelling telecommunication traffic with focus on signalling. The session explains the basics of air interface signalling with special focus on the slotted aloha random access protocol. The theory will be applied on an example of AVL message dimensioning. Additionally, the available signalling channels of TETRA will shortly be discussed.
Aim of the webinar is to have a clear understanding of the basics of telecommunication traffic theory and be able to dimension air interface signalling channels of a narrow band network like TETRA.
27/04/21 11 AM ET
This webinar introduces the basics of outdoor radio propagation and explains concepts like diversity reception and antenna patterns. Focus is on calculating the link budget and selecting suitable antenna configurations, depending on the requirements.
Aim is to understand the principle of radio propagation, being able to setup a link budget for a narrowband radio communication system and knowing different antenna configuration with their pros and cons.
29/04/21 11 AM ET
This webinar explains common concepts used for indoor coverage like off-air repeaters, optical repeaters or frequency sharing. Focus is on the link budget approach for distributed antenna systems and leaky feeders.
Aim is to understand the various concepts for achieving indoor coverage with their pros and cons and how to generate a link budget for coverage prediction.
25/05/21 11 AM ET
The webinar covers the basics of availability prediction in telecommunication systems. Focus is on how reliability block diagrams can be used to calculate the service availability, failure rate and maintenance intervals in complex networks.
Aim is to have a clear understanding of concepts used for availability prediction as well as being able to setup and read a reliability block diagram for a telecommunication system.
27/05/21 11 AM ET
The webinar covers the following four concepts in IP networking: what is the difference between switching and routing; how does IP multicast addressing work; what is the difference between TCP and UDP; and principles of congestion avoidance.
Aim is to understand various concepts used in IP networking and having a clear view which are the pros and cons of each method and which are typical use cases.
29/06/21 11 AM ET
The webinar introduces some optional features in TETRA and how they can enhance a narrowband telecommunication system. The selected features include subscriber classes, secondary control channel, aliasing, authentication and encryption.
Aim is to understand the capabilities of a narrowband system like TETRA and how to fulfil requirements related to capacity, usability, confidentiality and security.
01/07/21 11 AM ET
The webinar describes the key elements in LTE networks providing mission critical service. Focus is on interoperability with narrowband systems and how mission critical services can be deployed. The session also takes a critical view on issues to be addressed to meet the requirements for mission critical use.
Aim is to have a clear view on the network elements used for mission critical services over LTE. This will help to understand the possible deployment models related to common use cases.
