Intel RFID 收發(fā)器R1000集成了大約100個元件，它們傳送、調制、接受、處理這些來自EPC Gen2電子標簽的無線電通訊信息。R1000內包含了一個能源擴大器，使得它可以在近距離或者2米內對標簽進行編碼和閱讀，而具體距離是由閱讀器所使用的天線決定。有了額外的外部能源擴大器，使用R1000的讀寫器的讀寫范圍可以達到10米，并使RFID制造商可以降低他們生產的讀寫器和其它設備的價格。本文介紹了Intel RFID 收發(fā)器R1000的主要性能，方框圖以及系統(tǒng)應用軟件堆棧方框圖。

近年來，由于采用了不同行業(yè)和應用的多項技術，無源標簽的性能和標準制定方面都有了很大的進步。然而，標簽讀寫器方面的改革卻進展很緩慢。但這種局面將很快被一項高科技技術所改變。Intel的R1000時一個高度集成，特殊應用的集成電路（ASIC），此電路結合了專門用于無源超高頻RFID讀寫器的90％的離散元件，這些元件都集成到了一個芯片上。將這些元件集成到一個芯片上，這樣RFID讀寫器和打印機制造商就可以縮小讀寫器的外型大小并改善他們產品的能源效率——Intel公司聲稱一些制造商正在測試R1000。將離散元件集成到一個芯片上就意味著單獨的元件不再是分別起作用，所以讀寫器大大降低了工作瓦數。通過采用R1000或者其它走向市場的類似的讀寫器芯片，RFID制造商可以降低他們生產的讀寫器和其它設備的價格。
R1000集成了大約100個元件，它們傳送、調制、接受、處理這些來自EPC Gen2電子標簽的無線電通訊信息。根據Intel稱， R1000內包含了一個能源擴大器，使得它可以在近距離或者2米內對標簽進行編碼和閱讀，而具體距離是由閱讀器所使用的天線決定。有了額外的外部能源擴大器，使用R1000的讀寫器的讀寫范圍可以達到10米。R1000必須和單獨的微處理器連接，這個微處理器可以把由R1000數字信息處理器產生的原始數據轉換成EPC或者18000－6c格式的代碼。
Intel公司按照要遵守的標準給R1000提供固件，該固件使R1000可以支持Gen 2標準的密集讀寫器模塊(DRM)規(guī)格說明,在讀寫器部署密集的環(huán)境中改善讀寫器性能。同樣，固件還允許讀寫器制造商按照由美國通信委員會或者歐洲電信標準協(xié)會制定的監(jiān)管規(guī)定來生產產品。

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.

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.

主要特性和優(yōu)點：
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
