Mobil System Technologies 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 RF boards including PCB layout. 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. Previous Projects: Design of an ETACS phone as a Radio TelephoneInterface. 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 3volts GSM codec chip, using oversampling delta-sigma converters. DECT WLL signaling software development. Digital Enhanced Cordless Telecommunication (DECT): Digital Enhanced Cordless Telecommunication (DECT), the technology originated as a European initiative is now rapidly conquering the telecommunications world. More and more users, regulators, standardization bodies, network operators, and equipment manufacturers recognize the benefits offered by this high quality access technology. DECT has proven multiple applicability as a network access in residential, business and public environments showing easy mobility, speech quality comparable to wire line telephony, a high level of security through advanced digital technology and encryption, allowing for high subscriber densities, flexible bandwidth allocation, multiple service support, cost competitiveness, flexible deployment and simple installation. AOT's related projects have been in the area of handset design for GSM, D-AMPS and ETACS systems. In addition, AOT has already evaluated existing DECT handsets and base systems for manufacturing techniques and components used. Also an investigation on a DECT signaling software has been done. In this project, the focus has been on developing a generic software for DECT layers 2 and 3 for WLL systems. In order to prove the viability of the developed software, a traffic simulator has been used, which generates the signaling requirements in a small city or an industrial town.
