This research effort focuses on the impact that 4G/LTE wireless devices (e.g. cell towers and smart phones) may have on radar altimeters operating in the 4200-4400 MHz spectral band. Based on the identification of this band by the government as a potential candidate for commercial cellular use, the spectral characteristics and potential impact to the operation of these airplane landing radars has become extremely important to a broad audience. The recent crash of the Asiana Airlines flight has added to the focus on the operation of these radars.To obtain this understanding, a significant spectrum measurement campaign will be undertaken focused on appropriate radar altimeter systems and on 4G/LTE systems. The measurements will quantify the effects of 4G/LTE on radar altimeter performance using actual and/or simulated equipment. These measurement results will provide a basis for performing the detailed analysis work required to gauge the level of impact that would be expected under a variety of conditions. This information will need to be quickly and effectively disseminated to others in the wireless research community and importantly to various decision-makers in the telecommunications policy realm.

这项研究工作的重点是 4G/LTE 无线设备（例如蜂窝塔和智能手机）可能对在 4200-4400 MHz 频段运行的雷达高度计产生的影响。 根据政府将该频段确定为商业蜂窝用途的潜在候选频段，频谱特性和对这些飞机着陆雷达运行的潜在影响对于广大受众来说变得极其重要。 最近发生的韩亚航空航班坠机事件让人们更加关注这些雷达的运行情况。为了获得这一了解，我们将针对适当的雷达高度计系统和 4G/LTE 系统开展一项重要的频谱测量活动。 这些测量将使用实际和/或模拟设备量化 4G/LTE 对雷达高度计性能的影响。这些测量结果将为执行详细分析工作提供基础，以衡量各种条件下预期的影响程度。 这些信息需要快速有效地传播给无线研究界的其他人，尤其是电信政策领域的各个决策者。
