Next Generation Networks

NGN Access (NGA)

The key to enabling customers to connect to core Next Generation Networks is the NGA. The availability of high speed IP core networks supporting multiple services is only of benefit to customers if they have a suitable access network available. This can be provided through a number of different technologies which will determine the maximum data speed which they will obtain. NGA can be provided through:

• xDSL over copper
• Fibre to the kerb/cabinet
• Fibre to the home/premises
• Wireless

In practical terms, the closer that fibre can be provided to a customer, the faster the broadband services that can be provided. This is due to the limitations that copper cables impose on the delivered bandwidth of broadband services which especially affects FTTC network deployments that use copper for end user connections. Extensive fibre networks are however more expensive and present a higher level of risk to the investing operator. At the same time such investment significantly changes the structure of the access network and affects the services which can be provided at a wholesale level. This may become increasingly complex in markets where there is already extensive local loop unbundling. The strategies which network operators therefore adopt to such deployment are therefore very important to balance investment levels with a potentially much greater digital divide than currently exists. The use of open access networks is becoming increasingly popular in some situations to maximise the benefits from such investment and to comply with regulatory requirements for competitive access and equivalence.

InterConnect’s team of engineers have over 30 years experience of planning and rolling out access networks. InterConnect can therefore assist both regulators and operators to define and develop appropriate strategies for the planning and deployment of NGAs. Areas in which we can help include:

• Advising regulators on such changes to existing local loop unbundling guidelines as may be required to promote an NGN-friendly yet sustainable telecommunications environment;
• Assisting ISPs and other service providers negotiate robust and sustainable NGA agreements with network operators in order to facilitate the delivery of their products to end users;
• Undertaking network audits to assess the technical suitability of existing and planned network elements for handling NGN traffic;
• Advising on the design, planning and implementation of new NGA-compliant Open Access Networks, using both fixed-line and radio technologies;
• Assisting regulators, Regional Development Authorities and local government to understand the potential impact of NGAs on levels of broadband access and resulting economic and social benefits.
