Wireless communication is key to many schemes to reduce the environmental impact of transport and to provide the pervasive network access needed for future urban environments (including vehicle passengers). Thus, electromagnetic safety is a major issue in the design, operation and public acceptance of such systems. The EU has recently published limits for electromagnetic field exposure, but they do not readily apply to resonant environments such as vehicles and buildings. Also, the field distributions that arise in these structures are so complex that reliable assessment of the exposure by measurement is not practicable. This proposal therefore concerns the development and experimental validation of large-scale simulation methods to assess the characteristics of fields due to radio transmissions in such environments. Model content, analysis methods, efficient simulation strategies and field mitigation techniques will be addressed, using car and aircraft based case studies. This application is part of a DTI Technology Programme submission.

无线通信是许多减少交通对环境影响并提供未来城市环境（包括车辆乘客）所需的普遍网络接入的计划的关键。因此，电磁安全是此类系统的设计、运行和公众接受度的一个主要问题。欧盟最近发布了电磁场暴露限制，但它们并不容易适用于车辆和建筑物等共振环境。此外，这些结构中出现的场分布非常复杂，以至于通过测量对暴露进行可靠的评估是不切实际的。因此，该提案涉及大规模模拟方法的开发和实验验证，以评估此类环境中无线电传输造成的场特性。将使用基于汽车和飞机的案例研究来讨论模型内容、分析方法、有效的模拟策略和现场缓解技术。此应用程序是 DTI 技术计划提交的一部分。
