THE FUTURE ROLE OF TELECOM
September 2009
Open, interoperable fixed and mobile telecom networks are the result of systematic ways of working with open standards and clear interfaces. This is the way the industry has traditionally operated – with great success. Telecom as an interoperable, seamless service is taken for granted in most parts of the world.
Unlocking the value of operator assets
October 2009
Telecom operators have a strong hand that, if played right, can be used to develop very attractive end-user services. By making resources available to application developers, telecom operators can create an ecosystem for new services, and by choosing to cooperate among themselves and act together they can both reclaim lost ground and reach additional value chains.
Data retention: avoiding the traps
October 2009
The complexities and the costs of complying with the data retention rules and regulations must be carefully investigated by Communication Service Providers before they make any investment decision. Many common views on data retention systems are only partly correct and may generate misleading business perceptions. This paper analyzes some common statements and shows their weaknesses.
Optimizing global mobility through seamless coexistence and evolution of GSM, WCDMA and LTE
February 2009
The impressive uptake of mobile broadband services based on High Speed Packet Access (HSPA) is founded on excellent performance, low cost and seamless fall-back to GPRS/EDGE, which results in great coverage from day one. New technologies are being developed to further improve the coexistence of GSM and WCDMA and pave the way for the introduction of LTE.
Power supplies go digital
February 2009
Digital power techniques have been proposed for some time, but have not been able to compete successfully with analog solutions. Thanks to increasing integrated-circuit density, hard work on the part of semiconductor suppliers, and a mature and reliable, complementary, metal-oxide semiconductor technology, digital processing for power-conversion applications now is very attractive.
Synchronization in packet-based networks: challenges and solutions
January 2009
A range of technologies can be used to deliver synchronization solutions in next-generation packet networks. To ensure that the overall business objectives are met, the solution of choice is dependent on a detailed understanding of the requirements.
Innovations in WCDMA
March 2008
There are misconceptions about WCDMA’s development. Many wrongly believe it is an extension of the IS-95 standard, though it is the result of European and Japanese 3G developments, merging to create today’s global WCDMA standard.
