Simulation and Characterization of WLAN Indoor Channels at 60 GHz

This paper simulates and characterizes the 60 GHz band wireless channels for typical indoor. The Radio wave Propagation Simulator (RPS) is used to simulate the model characteristics. Simulations performed on the three rooms at Telematics Laboratory of Bandung Institute of Technology (ITB) those are Residency room, Computer Laboratory (size 1013 cm x 589.5 cm x 289.8 cm), and Undergraduate/Final Project room (size 900 cm x 1013 cm x 289.8 cm). The rooms were built with concrete walls in the left and right side with a thickness 14 cm, 0.5 cm for ceiling thickness, and the combination of walls and glasses at the front and backside of the rooms. The model characteristics were measured based on three classifications of distance between transmitter and receiver, i.e., CM1 (0 - 4 m), CM2 (4 - 10 m), and CM3 (> 10 m). We then obtain the model characteristics in terms of RDS value at 0.26 to 7.74 ns for the receivers at Residency room, 1.02 to 8.76 ns at Computer Lab and 2.07 to 15.65 ns at Final Project room. The system performances shown the coherence bandwidth is 1.2778 to 76.9492 MHz for frequency correlation above 90% and therefore the maximum bit rate that can be achieved with 1.25 spectrum efficiency is 60 Mbps.
