Telemedicine system requires an acceptable network quality of service and cost. IEEE 802.11 Wireless Local Area Network (WLAN) technology has been developed to provide scalable and low cost network. For telemedicine application however, the technology does not fulfil the quality of service requirement yet. Therefore, a cross layer design of Wireless Local Area Network (WLAN) is proposed to overcome this problem. The cross layer design based on H.264/Scalable Video Coding (SVC) and IEEE 802.1 le Wireless Network has been implemented in NS-2 simulation and IEEE 802.1 le Enhanced Distributed Channel Access (EDCA) prototype environment. The Network Simulator 2 (NS-2) simulation intends to deliver four traffic flows of telemedicine application with different priorities and to assign telemedicine video considering Quality of Service (QoS) provision over the proposed cross layer design of wireless LAN. In addition, the prototype intends to deliver telemedicine video with Quality of Service (QoS) guarantee over the proposed cross layer design of wireless LAN. The Network Simulator 2 (NS-2) simulation results show that the cross layer design can deliver 99.68 percent of video packets within average delay of 10.66 millisecond. Moreover, the experiments result of the IEEE 802.1 le Enhanced Distributed Channel Access (EDCA) prototype show that the cross layer design has the average delay value of 0.5 millisecond. Thus, this new design has a potential to be applied in the telemedicine system
