医疗行业是未来几年无线应用的潜在大市场。随着老年人数量的不断增加，对各种无线身体监测和测量设备的需求也在不断增加。然而，让任何一种电子设备靠近人体，甚至进入人体，都面临着挑战。对于无线体域网络（WBAN）解决方案，电池寿命需要长，设备必须安全使用，并且对其他电子设备无害。从功率使用的角度来看，最复杂的高性能接收器并不是最好的选择，因为它们往往具有高功耗，因此电池寿命短。本文在实际医院环境中比较了适用于低成本无线宽带网络方案的各种接收机的性能。超宽带（UWB）收发器系统遵循IEEE 802.15.a标准要求实现。WBAN信道模型基于在芬兰奥卢大学医院一间普通病房进行的测量。
Medical industry is potentially a big market for the wireless applications in the coming years. As the number of elder people is increasing, the need for various wireless body monitoring and measurement equipment is increasing as well. However, having any kind of electronic device next to the human body, or even inside of a body, faces challenges. For wireless body area network (WBAN) solutions, the battery life needs to be long, the equipment has to be safe to use and un-harmful also for other electronic devices. From power usage point of view, the most complex high performance receivers are not the best option since they tend to have high power consumption, thus short battery life. In this paper, the performances of receiver types suitable for low cost WBAN solutions are compared in a real hospital environment. The ultra wideband (UWB) transceiver system has been implemented by following the IEEE 802.15.4a standard requirements. The WBAN channel model is based on the measurements carried out in a regular hospital room in Oulu University Hospital, Finland.
