近年来，由于采用了不同行业和应用的多项技术，无源标签的性能和标准制定方面都有了很大的进步。然而，标签读写器方面的改革却进展很缓慢。但这种局面将很快被一项高科技技术所改变。Intel的R1000时一个高度集成，特殊应用的集成电路（ASIC），此电路结合了专门用于无源超高频RFID读写器的90％的离散元件，这些元件都集成到了一个芯片上。将这些元件集成到一个芯片上，这样RFID读写器和打印机制造商就可以缩小读写器的外型大小并改善他们产品的能源效率——Intel公司声称一些制造商正在测试R1000。将离散元件集成到一个芯片上就意味着单独的元件不再是分别起作用，所以读写器大大降低了工作瓦数。通过采用R1000或者其它走向市场的类似的读写器芯片，RFID制造商可以降低他们生产的读写器和其它设备的价格。 R1000集成了大约100个元件，它们传送、调制、接受、处理这些来自EPC Gen2电子标签的无线电通讯信息。根据Intel称， R1000内包含了一个能源扩大器，使得它可以在近距离或者2米内对标签进行编码和阅读，而具体距离是由阅读器所使用的天线决定。有了额外的外部能源扩大器，使用R1000的读写器的读写范围可以达到10米。R1000必须和单独的微处理器连接，这个微处理器可以把由R1000数字信息处理器产生的原始数据转换成EPC或者18000－6c格式的代码。 Intel公司按照要遵守的标准给R1000提供固件，该固件使R1000可以支持Gen 2标准的密集读写器模块(DRM)规格说明,在读写器部署密集的环境中改善读写器性能。同样，固件还允许读写器制造商按照由美国通信委员会或者欧洲电信标准协会制定的监管规定来生产产品。 The Intel UHF RFID Transceiver R1000 chip is a highly integrated, high-performance UHF reader radio chip that combines the primary functions of a UHF RFID reader.  Intel UHF RFID 收发器 R1000外形图 The Intel UHF RFID Transceiver R1000 sets a new standard for high integration, incorporating the complete transmit, receive, modulation, demodulation and baseband functions into one chip. This high level of integration significantly reduces design complexity by integrating up to 90% of the components required in a traditional discrete radio design. Intel’s new highly integrated UHF RFID transceiver chip and software deliver the key building blocks for the full range of UHF RFID readers, including everything from short-range embedded modules to long-range dock door readers. The flexible architecture allows easy design for mono-static or bi-static operation; low output power using the integrated power amplifier (PA); high output power using an external PA; and built-in optimization for dense reader environments. By reducing the complexity of UHF RFID reader designs, the Intel R1000 drives down the costs of design and manufacturing — enabling high-performance readers at lower price points. 主要特性和优点： Enables a complete range of UHF RFID applications and form factors. Lowers design complexity, cuts manufacturing costs, and increases reliability. Very low power, supporting power over USB for short range readers and Power over Ethernet (PoE) for high performance, long range readers. Transceiver and firmware support EPCglobal Gen 2 and ISO-18000-6C specifications, regional regulatory requirements and the full 860-960 MHz band Transceiver and software enable low-level diagnostics, remote management and provisioning, and easy integration Protocol firmware, programming tools, radio drivers and schematics all enable quick time-to-market The Intel R1000 provides robust support for the latest UHF RFID standards and worldwide regulatory requirements: EPCglobal Gen 2 and ISO 18000-6C Modulation modes: DSB, SSB, PR-ASK Dense Reader Mode (DRM) Supports all data rates Firmware configurable to operate from 860-960 MHz Compliance with FCC 47 CFG Ch. 1 Part 15 Compliance with ETSI EN 302 208-1 including built-in Listen-Before-Talk (LBT) support Intel UHF RFID Transceiver R1000 Features Product Features RFID reader radio on a chip ISO 18000-6C EPCglobal Gen 2 All modes and data rates Multiple geography support 860-960 MHz FCC 47 CFG Ch.1 Part 15 ETSI EN 302 208-1 Integrated power amplifier High-level integration Low external component count Enables new usage models 0.18μm SiGe BiCMOS process 56-pin 8mm2 QFN package Low power Configurable digital baseband RSSI Wideband Narrowband Tag RSSI Receiver sensitivity Down to -95 dBm (DRM) Down to -110 dBm (LBT)  图1。Intel UHF RFID 收发器R1000方框图  图2。Intel RFID 收发器R1000软件堆栈方框图 |
