Abstract
Field trials of 20 WLL systems of several technologies, developed by 13 different manufacturers, were recently hosted by 11 carrier companies of the TELEBRAS System, resulting in the largest and the most complete WLL field trials performed in the world so far. This paper presents some information about the history of these trials. The basic design and tests as well as the main results and conclusions concerning spurious emission, interference, coverage and service transparency to the users are presented. Due to the non-disclosure agreement established between TELEBRAS and the manufacturers, no results of a specific WLL product is presented, nor a comparison between them. The presentation of the results is general, at a level of detail sufficient to show the real potentiality of the WLL technology as a alternative to the wired network in the provision of high-quality telecommunications services. Additionally, the main features of the WLL technologies are presented.
