A summary of results obtained for radio over multimode fiber links and system demonstrations is presented. 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.
