Therefore BT sought tenders from parties interested to redesign and then manufacture a new generation product - to be called the "5G STU".
In preparing their tender for this opportunity, Pressac Communications approached us for assistance in the embedded firmware development.
The contract was awarded to Pressac in March 2008, and we were pleased to be able to assist during the development project.
For interchangeability with previous generations, Pressac's new design retains the original "foorprint" but, internally, an STM32 ARM Cortex-M3 processor is used instead of the 8051-based Triscend E5, and a WMP100 wireless microprocessor provides the GSM access, replacing the large WMOi3 "brick".
Having originally performed the development of the GSM communications on the GSM STU, our key role was again in implementing this onto the new platform. We were also able to offer some general assistance based on previous experience with the GSM STU, Keil tools, etc.
Deliveries of the new STU products are scheduled to start in September 2009.
We are grateful to Pressac for their kind permission to feature their 5G STU project in this article.
