These predictions are experimentally verified for WLAN signal transmission in an office environment, using a commercial access point and

It is stated that when using low-cost technologies such as pre-installed MMF and VCSELs, although adequate link performance is achievable, with careful design when taking into account the wireless path, MAC protocol effects may need to be considered for WLAN operation. For the simultaneous transmission of multiple signals, practical considerations of crosstalk and interference may cause an increase in the necessary complexity of remote antenna units

ET architectures are suitable for use with small systems of limited complexity: as systems grow, it may be necessary to migrate the existing code to a TT architecture. This paper is concerned with techniques which may be used to support the migration between ET and TT architectures.
