Symbian OS

Symbian History
            Symbian OS started life as EPOC - the operating system used for many years in Psion handheld devices. When Symbian was formed in 1998, Psion contributed EPOC into the group. EPOC was renamed Symbian OS and has been progressively updated, incorporating both voice and data telephony technologies of ever greater sophistication with every product release.

              Symbian OS is designed for the mobile phone environment. It addresses constraints of mobile phones by providing a framework to handle low memory situations, a power management model, and a rich software layer implementing industry standards for communications, telephony and data rendering. Even with these abundant features, Symbian OS puts no constraints on the integration of other peripheral hardware. Symbian OS is proven on several platforms. It started life as the operating system for the Psion series of consumer PDA products (including Series 5mx, Revo and netBook), and various adaptations by Diamond, Oregon Scientific and Ericsson.

Product Diversity
        There is an apparent contradiction between software developers who want to develop for just one popular platform and manufacturers who each want to have a range of distinctive and innovative products. The circle can be squared by separating the user interface from the core operating system. Advanced mobile phones or “Smartphones” will come in all sorts of shapes - from traditional designs resembling today’s mobile phones with main input via the phone keypad, to a tablet form factor operated with a stylus, to phones with larger screens and small keyboards.

            Small devices come in many shapes and sizes, each addressing distinct target markets that have different requirements. The market segment we are interested in is that of the mobile phone. The primary requirement of this market segment is that all products are great phones. This segment spans voice-centric phones with information capability to information-centric devices with voice capability. These advanced mobile phones integrate fully-featured personal digital assistant (PDA) capabilities with those of a traditional mobile phone in a single unit. 

Basic Principles 
            The cornerstone of Symbian’s modus operandi is to use open – agreed - standards wherever possible. Symbian is focused squarely on one part of the value chain - providing the base operating system for mobile internet devices. This enables manufacturers, networks and application developers to work together on a common platform.

        Symbian OS is a robust multi-tasking operating system, designed specifically for real-world wireless environments and the constraints of mobile phones (including limited amount of memory). Symbian OS is natively IP-based, with fully integrated communications and messaging.
