Five Russian communications firms – Comstar-UTS, Interregional TranzitTelekom, PeterStar, Prostor Telecom and Tango Telecom – have formed a partnership to launch commercial WLAN roaming across 17 cities in the country. Cities to be covered include Moscow, St Petersburg, Samara, Nizhny Novgorod, Krasnoyarsk and Sochi. Comstar-UTS and Tango Telecom are launching bilateral roaming within the project, i.e. all companies’ subscribers are able to use the access parameters received from their operator both in the ‘home’ and ‘guest’ networks. The Wi-Fi network aggregator for the project is MTT, which will provide the internet traffic exchange and collect the tariffs to carry out inter-operator payments. PeterStar has agreed to provide unilateral roaming, whereby its subscribers can connect to Comstar-UTS, Tango Telecom and Prostor Telecom. However, the subscribers of Comstar, Tango and Prostor are not able to connect to PeterStar network. PeterStar explained to CNews: ‘That is related to economic reasons. The roaming might become bilateral in the future.’
Digital TV transmission techniques that deliver most benefit in the worst reception environments have been developed by a consortium of European researchers. The technologies promise to reduce the network infrastructure needed for mobile TV, while minimising the power demands and complexity of mobile TV receivers of the future.
As electronics designers cram more and more components onto each chip, current technologies for making random-access memory (RAM) are running out of room. European researchers have a strong position in a new technology known as resistive RAM (RRAM) that could soon be replacing flash RAM in USB drives and other portable gadgets.
The growth of telecom services in emerging markets has attracted the interest of the biggest worldwide carriers, all of them grappling with mature markets at home, including the likes of Vodafone Group plc, France Telecom SA, and Portugal Telecom SGPS SA. But who is their competition? And which are the largest carriers operating solely in developing countries?
The Digital Opportunity Index is an e-index based on internationally-agreed ICT indicators. This makes it a valuable tool for benchmarking the most important indicators for measuring the Information Society. The DOI is a standard tool that governments, operators, development agencies, researchers and others can use to measure the digital divide and compare ICT performance within and across countries. The Digital Opportunity Index (DOI) is based on 11 ICT indicators, grouped in 3 clusters: opportunity, infrastructure and utilization. The DOI has been compiled for 181 economies for a period of three years from 2004-2006. An even longer time series for 62 leading economies for the period 2000-2006 is also available.
