Report on Impact of Adaptive Antennas on UMTS - v. 2

This is one of a series of reports on the application of adaptive antennas to the next generation of mobile communications systems.

This project "Technology in Smart Antennas from Universal Mobile Infrastructure" (TSUNAMI), was funded under the European Commission's RACE programme, is being undertaken by a consortium of seven European organizations led by ERA.

This report summarizes the results achieved in the course of the TSUNAMI project, specifically technical conclusions in the key areas related to the application of AA technology towards UMTS systems including: algorithms for AA processing, technology requirements-signalling and network functionalities and system performance of UMTS systems with AAs.

Short sections cover the benefits of AAs, the principle of beamforming and introducing AAs into MTS via an evolutionary approach.

The issues raised by adaptive algorithms and network implications are discussed.

Various aspects of array antenna technology are looked at, also transceiver linearity and dynamic range requirements.

Finally, AA UTMS impact is commented on and a brief overall prospective is provided.
