Delay and Throughput Performance of Uncompressed Video Streaming Service in mmWave WPAN

Existing WPAN solutions (IEEE 802.11 a/b/g, UWB) only have limited bandwidth and cannot support uncompressed video transmission. Instead, 60㎓ millimeter-wave(mmWave) band is an attracting method because it can provide huge bandwidth and achieve very high data rate(over 3Gbps). In this paper, we present the comparison of different superframe sizes in terms of delay and throughput for uncompressed video streaming in mmWave WPANs. We use the Constant Bit Rate (CBR) model to emulate the 1080p (30f 20b) video streaming. For simplification, we assume that an error-free PHY wireless channel is adopted. Simulation results show that the superframe size of 1/60s can result in better performance than that of 2㎳ for the uncompressed video service in mmWave WPAN. It is necessary to increase superframe size and use aggregation method, in order to achieve high throughput.
