Abstract

The paper addresses concerns about wireless local area network devices and two-way radios causing electromagnetic interference to aircraft navigation radio systems. Spurious radiated emissions from various IEEE 802.11a, 802.11b, and Bluetooth devices are characterized using reverberation chambers. The results are compared with baseline emissions from standard laptop computers and personal digital assistants (PDAs) that are currently allowed to be used on aircraft. The results indicate that the WLAN devices tested are not more of a threat to aircraft navigation radios than standard laptop computers and PDAs in most aircraft bands. In addition, spurious radiated emission data from seven pairs of two-way radios are provided. These two-way radios emit at much higher levels in the bands considered. A description of the measurement process, device modes of operation and the measurement results are reported.
飞机导航无线电便携式无线设备威胁评估
本文讨论了无线局域网设备和双向无线电对飞机导航无线电系统造成电磁干扰的问题。来自各种IEEE 802.11a、802.11b和蓝牙设备的杂散辐射发射使用混响室进行表征。该结果与目前允许在飞机上使用的标准笔记本电脑和个人数字助理(pda)的基线排放量进行了比较。结果表明,在大多数飞机频段中,测试的WLAN设备对飞机导航无线电的威胁并不比标准笔记本电脑和pda更大。此外,还提供了7对双向无线电的杂散辐射发射数据。这些双向无线电在考虑的频带中发射的电平要高得多。报告了测量过程、设备工作模式和测量结果的描述。
