    In a GSM cellular system, and generally in any cellular system, the operator has to carry an essen- tial task of optimizing the system which is an ongo- ing need for the life of the system operation. Optimization is normally understood as the tuning of the radio interface in order to offer the sub- scribers the best...

    This paper deals with the implementation of the LDMOS PA (Power Amplifier) module and the power control loop associated with it in VHF/UHF HAMMER portable radios, and modifications that have been made to meet the ETSI requirements. One of the requirements was to change the radio's circuits so that they will...

    Current flip chip assemblies require encapsulant material for enhanced reliability performance. Encapsulant is used to couple the die mechanically to the substrate to constrain the board during ther- mal excursions and to reduce the stress transferred to the solder joints. Underfilling the die with encap- sulant...

    Future pagers will offer FlexTM Suite-based advertising. One aspect of this protocol allows a Data Center to download 'advertising-based-mes- sages' to a pager, and then associate particular addresses or Flex SuiteTM 'topics' with particular advertisements. The advertisement is to be present- ed before, during, or...

    GSM Networks process originating calls at a Gateway MSC. Currently, this network element must determine whether the number dialed is a mobile number on the same network, or a PSTN number. A routing table is maintained within the MSC which analyzes the number dialed, and deter- mines (usually from the prefix) the type...
