* The two-phase approach proved to be a
popular option for our new customers as they have an opportunity to asses the
level of service provided before making the decision of proceeding with the
final stages of the project. Phase One normally includes, theory of operation,
mathematical modelling, performance prediction, design of the
algorithms, hardware requirements. Phase One costs
about 25% of the total project cost.

Key Advantages of Our Approach to R&D
- Our specialists
in Microelectronics, Information technology have long-term experience of
working together on R&D projects for
western customers.
- Affiliation with leading Academic and
Research establishments provides for expertise in any area of natural science
and engineering: Mathematics, Communications, Navigation
etc.
- A substantial pool of R&D development
resources allows the selection of the right project leader and the forming of a
strong project development team.
- Each project is carefully planned and
separate tasks are clearly defined.
- Manpower are
allocated to the specific tasks in accordance with required time and skills.
This approach results in unbeatable low average development costs and timely
delivery of the results.
- Project price is calculated on the basis of
a Gantt Chart schedule agreed between customer and
SEDAM Communications Ltd.
- Current rate is 15US$/hour and valid for
R&D Projects ordered by
- All communication and correspondence is in
English.

Component and OS Base
We
can design complex electronic systems based on a variety of microprocessors and
using different operating systems. However, we would like to emphasise our
experience in fast, low-cost, power-efficient ARM processors and Embedded Linux
Operating System.
