MOBILE MULTI GIGABIT (MOGIG) WIRELESS NETWORKS AND TERMINALS - 5000X WORKING GROUP



Evolutionary & Disruptive Visions Towards Ultra High Capacity Networks

The aim of this whitepaper is to advance certain understandings and concepts for adoption in wireless systems to be deployed beyond the year 2020, what is referred to here as “5G.” While this whitepaper does not authoritatively prescribe what “5G” standards are or of what they will consist, the paper presents technical details and tradeoffs that should be considered in defining “5G.” It is expected these contributions will empower the networks beyond 2020 with critically needed spectrum, air interface advances, and architectural structure to address the rapidly developing demands and imaginative new applications envisioned for this next decade.

Reliability Prediction Methods for Tower Top Electronic Systems

The purpose of this white paper is to remove some of the mystery of how reliability and especially failure rates are determined. Prediction methods are described and examples of how they are used for Tower Top electronic systems are given. These methods include using underlying physics of failure, empirical results from customer returns and accelerated tests to determine failure rates.

TUNABLE COMPONENTS AND ARCHITECTURES WORKING GROUP


RF Tuning in Cellular Handsets: Employing tuning to address Multi-Mode, Multi-Band RF Front-End Challenges

The main objective of this whitepaper is to provide the reader with an overview of RF tuning as applied to the cellular handset. This technology is available to significantly improve handset performance for RF communications. After reading this whitepaper, the reader should appreciate the uses of RF tuning and see where this technology can be applied to current and future products.
