Networks

Efficient telecommunications facilities are essential for society, the emergency services, the military and, of course, for individuals. TNO Information and Communication Technology plays an important role by providing impartial advice on the use of fixed and wireless communication technologies and by developing innovative solutions for deploying these technologies as efficiently as possible.

In recent decades, telecommunication technologies have developed at lightning speed. This has led to considerably faster data speeds for end-users and has paved the way for new services. The trend is expected to continue in the years to come. All communication systems involve transporting a signal over a medium. The medium can be a fixed connection (e.g. twisted-pair, coax or fibre-optic cable) or a wireless connection (radio). The reliability and capacity of a communication system depend on a range of factors including the transmission method (e.g. modulation and coding), the distance between source and receiver, transmit power, available bandwidth, and noise environment. Highly specialised knowledge is required to design cost-efficient networks that provide sufficient capacity, quality and – in the case of wireless networks – coverage.

Efficiency is the key

Fixed and wireless communication networks are costly, and consequently seen as a long-term investment. Operators therefore want to deploy and utilise their infrastructure as efficiently as possible. One example is the twisted-pair cables originally intended for narrowband voice applications. Thanks to DSL technology, those cables can now be used to transmit data at very high speeds. Making the right decisions and investments requires knowledge and understanding of technological developments and their possibilities – as well as their limitations.
At the public level too, there are issues to address with regard to transmission technologies and their properties. Radio frequency is scarce and must be used efficiently. User rights are therefore granted by the government, and users and equipment must comply with requirements. The government also introduces regulations for market players and for access to the communication infrastructure of other parties.

TNO activities

TNO provides consultancy, develops tools and gives independent advice on using fixed and wireless communication technologies. Examples of TNO's activities:

    For operators of fixed networks (xDSL, Coax, HFC, FTTx):
  • Developments, achievable bitrates, testing and system analysis
  • Design and standardisation of spectral management for twisted-pair transmission
  • Development of tools and methods for predicting transmission quality
