Ericsson Mobile Platforms S330

Year: 2007
Prototype level: Platform
Codename: Carolina

Overview

The Ericsson Mobile Platforms S330 is a reference design from the later period of Ericsson Mobile Platforms, created to provide handset manufacturers with a ready-made hardware and software foundation rather than a phone intended for consumers. The S330 belongs to the U330 platform family and was developed as a working test product around Ericsson’s mobile-platform technology. Contemporary software and development documentation from the period even identifies the S330/B330 combination specifically as an Ericsson prototype platform.

Reference designs such as the S330 served a practical purpose: they allowed engineers to evaluate the platform as a complete system before committing it to a particular commercial handset design. The electronics, operating environment and supporting interfaces could be tested on the reference hardware while manufacturers concentrated on their own industrial design and applications. This approach was central to Ericsson Mobile Platforms’ business model, which supplied the underlying technology used by other handset manufacturers rather than selling the reference devices themselves.

The S330 therefore represents the less visible side of mobile-phone development. It is not an unreleased consumer model, but a physical development platform that existed to make future products possible. Surviving examples are consequently much closer to engineering tools than conventional mobile phones, preserving a piece of the hardware that sat between Ericsson’s platform development and the finished handsets that eventually reached the market.
