The volume of IP (Internet Protocol) traffic has already exceeded that for circuit-switched traffic in most fixed networks. Two key technologies, HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access), offer breakthrough data speeds - theoretically up to 14.4 Mbps in downlink and up to 5.8 Mbps in uplink respectively - clearly higher than the most advanced 3G networks. The Nokia High Speed Packet Access solution benefits network operators by improving the WCDMA network's packet data capacity and enhancing spectral efficiency. tech news

Mobile technology is changing the boundaries of the traditional workplace. We examine the ideas and initiatives that are driving mobility, and where theyll take us in the years to come. Mobile technology is continuing to develop towards greater productivity and improved workplace flexibility. Part of this process will require a more seamless means of moving between one network and the other, as well software that adapts to its connection state. Voice over IP technology will gain a stronger foothold, enabling cheap international voice communication wherever there is a wireless network. Hardware devices are also gaining multi-modal interfaces, enabling users to speak, write or type depending on what suits them. Finally, the attitudes and traditions of the traditional workplace are gradually being re-evaluated to embrace the benefits of an increasingly mobile workforce.<!-- mobile technology, workplace, mobility, productivity, flexibility, VoIP, Voice over IP, voice communication, wireless, multi-modal interfaces, mobile workforce --> tech news

The hardware driving mobility is faster, safer and more portable than ever. We take a look at whats available today, plus the latest market and security trends. With corporate cost cutting on the way out and investment in innovative technologies on the way in, theres never been a better time to take advantage of mobile hardware. New security encryption standards ensure that wireless data is safe from prying eyes, and advances processor performance, form factor, battery life and weight mean a better mobile experience. With a choice of desktop replacement or ultra-light notebooks, plus the versatile Tablet PC and handy Pocket PC form factor, theres a portable solution for everyone.<!-- mobility, technology, trends, security, inovation, notebooks, tablet pc, pocket pc, portable, mobile hardware, battery life --> tech news

How often should you replace PCs and notebooks? Whats the best way to maximise ROI? We investigate the implementation and management of mobile technology in the enterprise. Gaining a stronger return on your investment in mobile technology can be realised by implementing a shorter product lifecycle. Using the latest hardware, staying within your equipments warranty period, and applying other industry best practices can help you get the most from your client base. By employing mobile management software, such as Toshibas ConfigFree, its easy for users to connect to a variety of different networks without Helpdesk intervention. Mobile technology can also help realise the Real-Time Enterprise model, where off-site staff can communicate with CRM and ERP systems in real-time, creating a far more reactive and competitive organisation.<!-- PCs, notebooks, mobile, technology, hardware, real-time enterprise model, CRM, ERP, mobile management software, ConfigFree, Helpdesk intervention --> tech news

The demand for greater bandwidth generally creates a need for increased network capacity. The telecommunications industry has responded to this demand with the design and deployment of new DWDM (dense wavelength division multiplexed) and high bit rate TDM (time division multiplexed) optical transport systems with capacities from 40 Gbps to 1.6 Tbps. These higher bit rates and narrower spaced channels make it necessary to examine impairments such as continuity, dispersion, and distortion, in order to qualify network performance, especially in uncharacterized and/or non-standard plants. In this paper, methods and procedures for the characterization of fiber optic networks are developed, data and results from field experiences are described, and the effect and impact on typical network configurations are discussed. tech news
