RFID: Read Range and Standards
This slide provides an overview about the different Frequency standards. On the left-hand side, you can see that the LF and HF Passive technology starts at 125 kilohertz and 134.2 kilohertz and also includes the 13.56 megahertz area. On the right-hand side, there are UHF Passive and UHF Active systems spanning within the UHF range, 868 to 950 megahertz on the UHF passive side, and 433 megahertz to 5.8 gigahertz on the active side. On the left-hand side, you can see our antenna, our reader/writer infrastructure is a close-coupled system, meaning you have to be very close to the antenna in order to read and exchange read/write data. The Proximity technology is usually based on ISO 14443 standards and NFC and also includes all the NFC standards. It gives us approximately a 10 centimeter range. And it's typically used for secure cards and secure applications under a 13.56 megahertz frequency. On the same frequency, we also have Vicinity standards and Vicinity technology. This provides more range, up to 1.5 meters, and includes 13.56 megahertz frequency, as well as the LF passive range, using 125 or 130 for kilohertz. Now we move to a bit of a longer range, up to 10 meters. That's the Long Range UHF Passive system. You may have heard about EPC which is being used by Walmart and other large retailers. The majority of these tags are 868 to 950 megahertz. Again, there is a broad frequency range because we don't have a unique single frequency band across the globe. At a much longer range, of course, are UHF active tags. These are radios, like your walkie talkie, and can see ranges even in miles. 这个幻灯片简要介绍了 不同的频率 标准。 在左手边,您可以 看到 LF 和 HF 无源 技术开始于 125 千赫和 134.2 千赫, 还包括 13.56 兆赫区域。 在右手边, 是 UHF 无源和 UHF 有源 系统,跨 UHF 范围, UHF 无源端 868 到 950 兆赫 ,有源端 433 兆赫到 5.8 千兆赫。 在左手边, 您可以看到天线, 我们的读取器/写入器基础设施 是一个紧耦合系统, 这意味着您必须 离天线非常近 才能够读取和 交换读取/写入数据。 接近 技术通常 基于 ISO 14443 标准和 NFC, 还包括所有 NFC 标准。 它给了我们大概 10 厘米范围。 通常用于 13.56 兆赫频率 以下的安全卡 和安全应用。 在相同频率, 我们还有邻近标准 和邻近技术。 这提供了更多 范围,最长达 1.5 米, 包括 13.56 兆赫 频率,和 LF 无源范围,使用 125 或 130 千赫。 现在我们来看看稍微 长一点的范围,最长 10 米。 这是远程 UHF 无源系统。 您可能已经听说过 EPC, Walmart 和其他大型零售商 都在使用它。 这些标签中大部分是 868 到 950 兆赫。 同样,存在 宽频范围, 因为在全球范围内, 我们没有 独特的单频带。 当然,长出很多的范围 使用 UHF 有源标签。 这些是无线电,就像 您的对讲机, 可以达到数英里 范围。
