Mobile Communications (GSM)

While staying at the forefront of the mobile technology, the driving force behind advanced technology in the last decade of the 20th century, we embrace the 19th century philosophy of meticulous attention to detail, service and quality. We have a proven ability to develop RF modules and advanced digital signal processing algorithms for mobile base bands. We have the ability to analyze existing protocol standards and debug existing signaling software in detail. We are able to develop very efficient production test set-ups for complex RF systems.

Capabilities:

• Communications systems architecture and protocol analysis.
• Personal Communications, RF, baseband DSP, and protocol software design and development.
• Design of Complex RF boards.
• Custom test software and hardware setups for production.
• Protocol analysis of communication systems from standards such as GSM, DECT, DAMPS, ETACS and the evolving 3G systems.
  

• Design of an ETACS phone as a Radio Telephone Interface.
• Design of GSM Handsets.
• Development of GSM baseband DSP.
• Design of a family of cordless telephones for various standards including software and test setups.
• Spread spectrum cordless telephone architecture.
• Analysis of the protocol for the DAMPS base station.
• Design of a DAMPS WLL RF unit.
• Modeling and analysis of efficient RF amplifiers for mobile base stations.
• Wireless Local Loop, user terminal for the GSM standard.
• Design of a 3 volt GSM codec chip, using over sampling delta-sigma converters.
• DECT WLL signaling software development.
