Broadcast | ATDI


ATDI helps broadcasters attain their goal of reaching the widest audience.

Even when spectrum resources are squeezed, ATDI is trusted to ensure radio and TV stay on the air.

ATDI helps broadcasters avoid interference in congested urban spectrum, as well as ensuring their signals reach isolated rural communities.



Broadcasters constantly battle with the need to adopt new technologies but struggle with the age-old issue of spectrum scarcity. This problem is escalated by public demands for 24/7 access to broadcast services, on-line programmes and more. In urban areas, where the spectrum is most congested, this is problematic at best; however, broadcasters face tough times rolling out networks in rural areas where signals are not present.

In the cities, the broadcasters have a dual co-existence problem. The frequencies carrying their streaming services must sit alongside – and not interfere with – all the other signals in the air; and the TV broadcasters must also not create nor suffer from interference, particularly when new services such as mobile broadband emerge and have to be slotted in next to traditional TV broadcast frequencies.

ATDI has addressed these issues and more and has identfied solutions that enable traditional broadcast technologies to propagate, as well as allowing third-millennium services to flourish.

Case: Switching from analogue to digital broadcasting


Switching from analogue to digital broadcasting maximises the use of existing infrastructure and minimises capital expenditure.


ICS telecom EV’s ‘select stations’ function identifies the sites which cover the largest area or population, minimising the number of sites needed to provide the service. In conjunction with the ‘power optimization’ feature and other tools, operators are able to assess potential savings by reducing transmitter power.


Case: Population analysis


Population analysis starts with distribution modelling. ICS telecom EV models population in different ways including lists, vectors and rasters to provide maximum accuracy.


ICS telecom EV creates reports covering:

  • Percentage and total number of the covered population
  • Total number of the covered population for each station
  • Settlements in the service area for each station
  • Percentage of the covered population in each settlement


Case: Coexistence with mobile and other services


The re-use of former broadcast spectrum by mobile operators creates potential interference issues for broadcasters.


ICS telecom EV calculates potential interference in a variety of ways. For instance, intersystem interference there are special functions and algorithms (ie, ITU SM1009 recommendation for broadcasts vs ILS). However,  sometimes users need more general tools to analyse interference. In this instance, ICS telecom EV manages spectrum masks for the transmitter signal and rejection filters of the receiver and calculates interference based on spectrum convolution. Interference can be analysed as broadcast Tx vs mobile Rx, mobile Tx vs broadcast Rx, interference coverage, P2P interference.
