Ericsson/Mannesmann GSM field-trials with adaptive antennas

This paper describes Ericsson's GSM testbed for evaluation of adaptive antenna technology and joint field-trials made by Ericsson and Mannesmann Mobilfunk. The implementation principles and algorithms are briefly described together with the field-trial setup. The field-trials are carried out in Dusseldorf, Germany, by Mannesmann Mobilfunk and Ericsson. The paper also presents results from the field-tests.
