Ericsson Review
Open communication devices using the EPOC operating system
Written by: Anders Waesterlid
Download PDF file
To fully utilize the capability of new technologies, GPRS, Edge, UMTS, and other third-generation cellular standards need a whole new class of communication devices. In the last couple of years, Ericsson has investigated the software requirements for the advanced third-generation of cellular devices. This research involved evaluating in-house solutions as well as several non-Ericsson software solutions. Ericsson chose the EPOC operating system.
The author describes the architecture and key characteristics of EPOC, the client-server framework, and the user-interface design, which together offer an unprecedented level of openness in Ericsson’s new range of communication devices.
