The results show that with minimal optimization, directly modulated ROF WLAN 802.11g signal at 2.4 GHz and externally modulated 1.25 Gbps baseband signal can coexist in the 2 km IM/DD optical link with a power penalty of 3 dB. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 52:812–815, 2010; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.25029
