This paper presents the feasibility of a wireless network coding prototype system based on time division multiple access using the global positioning system to facilitate the time synchronization of wireless nodes. We evaluate the system throughput of the prototype system with wireless network coding and Ethernet frame aggregation in the full buffer traffic environment assuming web browsing and voice over Internet protocol. The experimental results show that the prototype system improves the system throughput by approximately 1.85-fold compared to a system without wireless network coding or aggregation even in a multipath Rician fading environment.
