Developing ultra-low power integrated circuits
is a NemeriX core competence.
The NemeriX power advantage stems from proprietary and patented expertise at the system and block level, as well as customized design of features such as pad rings and carefully controlled layout.
Further power savings are derived from intelligent management of on-chip voltage levels, which requires a holistic approach to hardware and software development.
Combining NemeriX's deep interdisciplinary know-how with continued investment in specialized low-power design flows, the outcome is chip-level power savings of around 60% compared with competing GPS designs.
Based on location accuracy and ease of implementation, Assisted GPS (A-GPS) has been selected as the preferred technology to support the implementation of location based services (LBS) for the mobile industry.
Various technology initiatives have been considered in response to the requirement to support the E911 (US) and E112 (European) initiatives to provide location information to dispatchers handling emergency calls.
The identity of the cell where the mobile phone is currently located is information that is readily available, without the need to change the handset or modify the cellular infrastructure.
However, depending on the base station density, the accuracy may only be in the range from 100m to 300m. Despite the attractiveness of getting location information for free, the accuracy is just not good enough.
