“…However, most of these studies used a vector or a spectrum network analyzer [4][5][6][7]. Recently, a prototype BAN system based on UWB has been evaluated in anechoic chamber [8] or experimental room [3], but not in a real hospital room. So, we applied UWB-BAN in a hospital room where real time vital data information of patients is essential.…”

We evaluated a prototype high-band UWB-BAN using several vital information sensors in a hospital. We confirmed by experiments that setting one coordinator near the ceiling or back or forward of the bed and another coordinator under the bed is better solution when the patient lies on a bed. A helical antenna with a high antenna gain along the axial direction, when used in the coordinator showed better radiation performance and less dependence on the direction of the sensor node antenna than a biconical antenna. Next we applied new version of prototype with smaller size of hub and sensor node with more mobility models in a hospital attaching a hub and sensor nodes on the body and confirmed the communication worked well. We also examined the interference by other wireless communication system and medical device and optimized the sequence length to get maximum data rate and satisfying the packet rate and suppressing the interference under multi BAN by numerical analysis.

This paper presents an experimental evaluation of communication during human walking motion, using the medium access control (MAC) evaluation system for a prototype ultra-wideband (UWB) based wireless body area network for suitable MAC parameter settings for data transmission. Its physical layer and MAC specifications are based on the draft standard in IEEE802.15.6. This paper studies the effects of the number of retransmissions and the number of commands of GTS (guaranteed time slot) request packets in the CAP (contention access period) during human walking motion by varying the number of sensor nodes or the number of CFP (contention free period) slots in the superframe. The experiments were performed in an anechoic chamber. The number of packets received is decreased by packet loss caused by human walking motion in the case where 2 slots are set for CFP, regardless of the number of nodes, and this materially decreases the total number of packets received. The number of retransmissions and the GTS request commands increase according to increases in the number of nodes, largely reflecting the effects of the number of CFP slots in the case where 4 nodes are attached. In the cases where 2 or 3 nodes are attached and 4 slots are set for CFP, the packet transmission rate is more than 95%. In the case where 4 nodes are attached and 6 slots are set for CFP, the packet transmission rate is reduced to 88% at best.
