The capabilities of today's digital subscriber line (DSL) technology are being stretched to the limit. Residential and business subscribers need more and more bandwidth, especially for applications such as interactive personalised TV, high definition TV (HDTV) and video-on-demand, which are growing in popularity. Ultimately the answer may lie in running fibre out to the building, or at least to the kerb, to deliver virtually unlimited bandwidth. In the meantime, most operators must look for new cost-effective ways of exploiting their existing copper infrastructure to deliver the speeds that subscribers need. The very high bitrate DSL 2 standard (VDSL2) offers looks set to fill the gap neatly. - Author(s): J. Brunzel

Pushing optical fibre closer to end users presents significant new challenges to service providers all over the globe. Infrastructures and methodologies differ from country to country and, to date, many have been quite happy with their physical plant despite virtually no overhead distribution and very little buried fibre cable. In most cases, there is little likelihood that any new physical plant will be deployed any time soon. Rather, service providers are seeking the best way to use existing ducted infrastructures to deliver new services and the highest possible speeds, to customers. The key for network planners is to consider - in the early stages what architectures will make the most sense for building a flexible network that will take them into the next decade of high-bandwidth demand. - Author(s): M.

If the advent of the Internet took networked communications global, then the transformational technologies that have become synonymous with the `Web 2.0' trend promise to humanise this now pervasive virtual world of information exchange. Web 2.0-based technologies now promise to empower computer end-users to customize their user experience more effectively than ever before, and share information in more efficient and collaborative way. Web 2.0-based technologies are expected to have a significant impact on a broad range of traditional enterprises. Postive business model change should result in unexpected ways, and enterprises must prepare for this transition. - Author(s): C. Macleod

The FBI reports that about 70% of all computer security breaches are perpetrated by internal hackers, i.e., ordinary employees who are motivated by curiosity, revenge or industrial espionage. With as much as 20% of workstations still set to their default passwords, hackers can easily work around these to gain access to sensitive company information. To minimize hacking incidents, organizations are encouraged to use automated ways to securely change priveleged passwords. - Author(s): D. Mulvey

This paper explains how 3G high speed packet access (HSPA) works. High-speed packet access in both its flavours, HSPDA for the downlink and HSUPA for the uplink, is a hot topic in 3G. The real breakthrough has been achieved by dramatic improvements in the physical layer. This article explains what they are and how they lead to the kind of data rates needed to guarantee 3G a future in the evolution towards all-IP networks. - Source: Communications Engineer, Volume 5, Issue 1, p. 42 –43
