High efficiency power amplifiers

Demands for greater capacity and higher data rates must be met within the existing RBS footprint where cooling capacity and size are limited. At the same time, they must allow operators to cut OPEX, of which energy consumption is a significant factor. More efficient base station power amplifiers are thus a crucial factor in the context of mobile system evolution.

New high-quality voice service for mobile networks

The new AMR-WB codec doubles the audio bandwidth of voice communication with a coding bit rate which is similar to that of AMR-NB. Radio network planning for AMR-NB is therefore suitable for AMR-WB. Radio network capacity is also similar. AMR-WB can thus co-exist with AMR-NB in a network planned for AMR-NB.

Fifty years with mobile phones - From novelty to no. 1 consumer product

This year marks 50 years since Ericsson introduced the first truly automatic mobile telephone system. The extraordinary success of mobile communications, from those early pioneers’ efforts to today’s miniature telephones and advanced services, reads like a page from a storybook. From the outset, Ericsson has been a major player, driving many facets of development and helping to create the standards that prevail in the industry today.

Evolving the TV experience – Anytime, anywhere, any device

IPTV must quickly evolve into a personalized, interactive service that is well integrated with communication services and has inherent support for portable and mobile devices. The most promising approach is to build on IMS, which already provides an open framework for voice and multimedia communication services across fixed and mobile devices.

Realizing real-time charging

Real-time charging differs from non-real-time charging. Among other things, it is an integral, ongoing part of the service; it cannot handle the aggregation of information; in converged networks, the subscriber identity is not necessarily the MSISDN; and it must accommodate different classes of service and content. With these differences in mind, Ericsson has defined a real-time charging mechanism and process for assessing charges for specific services.

HSDPA performance and evolution

HSDPA is rapidly becoming a commercial reality in numerous networks around the world. Measurements made in live networks show impressive performance. Following a strong start, HSDPA will continue to evolve through numerous performance enhancements that make HSDPA services even more appealing to end users and provide the system capacity needed to support rapid service uptake.
