CTA CEB18提出了一系列规定，这些规定共同构成了一个功能集，概述了术语和指标，以确定传输便携式电子设备（T-PED）的传输和运行状态，并便于控制T-PED中的发射机，以帮助管理其在敏感电子环境中的使用。在本推荐实施规程中，T-PED被视为向公众出售的手持移动通信或计算设备，有意传输射频（RF）无线信号。本推荐实施规程概述了共同构成一个功能集的相互关联的规定，其中这些功能被理解为是针对产品中使用的所有无线技术的整体实现。 一致性假设功能集中的所有规定都得到了满足，而不一致性假设任何一项或多项规定都没有得到满足。本推荐规程涉及技术和/或行业标准中定义的无线技术，并广泛应用于消费品（如CMRS/蜂窝网络系统、WiFi、蓝牙）。制定无线技术标准或在消费品（如UWB、802.15.4、WMT）中尚不常见的无线技术在本次修订中未提及，但在后续修订中可能会提及。本推荐规程中所述的无线技术大致分为以下几类:； 本文无意提供射频信号或技术的详细描述1。本推荐规程不包括红外发射器和接收器。

CTA CEB18 sets forth a series of PROVISIONS that collectively constitute a FEATURE SET outlining TERMINOLOGY and INDICATORS to determine TRANSMIT and OPERATIONAL STATUS of Transmitting Portable Electronic Devices (T-PEDs) and facilitate ease of operation in controlling transmitters in T-PEDs to aid in managing their use in sensitive electronic environments. For the purposes of this Recommended Practice, T-PEDs are considered to be handheld mobile communication or computing devices for sale to the general public that intentionally transmit a radiofrequency (RF) wireless signal.This Recommended Practice outlines inter-related PROVISIONS that together constitute a FEATURE SET, where the features are understood to be implemented collectively and in their entirety for all wireless technologies used in a product. Conformance assumes satisfaction of all PROVISIONS in the FEATURE SET collectively, and non-conformance assumes any one or more of the PROVISIONS have not been satisfied.This Recommended Practice addresses wireless technologies that are defined in technical and/or industry standards and widely available in consumer products (e.g., CMRS / cellular network systems, WiFi, Bluetooth). Developing wireless technical standards or wireless technologies not yet common in consumer products (e.g., UWB, 802.15.4, WMTS) are not addressed in this revision, but they are mentioned and might be addressed in subsequent revisions. Wireless technologies as described in this Recommended Practice are broadly classified into categories; it is not the intention here to provide a detailed description of the RF signal or technology subtype1. Infrared transmitters and receivers are not covered by this Recommended Practice.
