ABSTRACT

Federal Communications Commission (FCC) has released the regulation for medical body area network (MBAN) in 2012 as a BAN specialized for medical applications. MBAN is a narrowband BAN allocated on the 2360-2400 MHz frequency band. It is very promising, as it has the advantages of BAN modules like low power and high accuracy, which are essential parameters for medical applications. This paper provides a comprehensive study of the on-body MBAN operating in the 2360-2390 MHz band. In particular, it introduces link budget signaling parameters required for reliable transmission of biological signals for the MBAN channels, and investigates the bit-error-rate (BER) and maximum allowable data throughput performances assuming different node positions and body activities. Numerical results show that a single arm receiver is ideal for medical applications that do not require movement. Moreover, the relative movement between the transmitter and receiver nodes highly affects the performance of the link.

摘要

联邦通信委员会（FCC）已于2012年发布了针对医疗机构局域网（MBAN）的法规，作为专门用于医疗应用的BAN。MBAN是分配在2360-2400 MHz频带上的窄带BAN。这是非常有前途的，因为它具有BAN模块的优势，例如低功耗和高精度，而BAN模块是医疗应用中必不可少的参数。本文对在2360-2390 MHz频段上工作的人体MBAN进行了全面的研究。特别是，它引入了MBAN信道可靠传输生物信号所需的链路预算信令参数，并假设不同的节点位置和主体活动，研究了误码率（BER）和最大允许数据吞吐量性能。数值结果表明，单臂接收器非常适合不需要移动的医疗应用。此外，发送器和接收器节点之间的相对运动会极大地影响链接的性能。
