Ultra-high frequency (UHF) 865-868 MHz is the ETSI standard frequency span used all over Europe. It meets the standards of the European Union. Gao’s UHF 865-858 MHz readers combine WCDMA (HSUPA) /EDGE/GSM/GPRS communications, integrated A-GPS and WLAN connectivities and also provide an option to communicate through TCP/IP, Wiegand 26/34, RS232/485 interfaces which can be altered. In addition, most of these readers present a variety of alternatives for data relocation to the host through Bluetooth or USB which enables effortless connection to devices like PDAs, laptops or smart phones. Some of our readers offer a 3.5 inches high definition touch screen display and a large memory capacity (256 MB RAM and up to 2 GB ROM Flash). They are also provided with an SD/MMC card slot and a SIM card slot for data communication. The portable readers bear multi-reader synchronization function, and also contain a pivot head to provide the best possible read rates regardless of tag alignment and make the device user-friendly (Dense Read Mode available). The mid-range UHF RFID readers utilize proficient digital signal processing algorithm and allow fast tag read/write operation with high identification rates. They possess a variety of characteristics, including RFID reading, barcode 1D/2D scanning, GPS location, and image acquisition operations. These readers meet  both the ISO18000-6B and ISO18000-6C protocols. They offer low power consumption using a 9V DC power supply with a battery life of four years. A supplementary feature present on some of the readers is a built-in circularly polarized antenna (typically 12dBi) with an exceptional axial ratio to ensure excellent read zone control. Furthermore the range of RF power is 0 to 30 dBm which is convertible via software. These are designed to be compatible with either Windows CE 5.0 or Windows Mobile 6.5 or Linux operating systems.

Applications of ultra-high frequency (UHF) 865-868 MHz readers include fixed asset management, asset tracking, vehicle inspection, outdoor patrolling vehicles, vehicle tracking, industrial production process control, logistic, inventory management, cargo tracking management, warehouse management, shop floor management, class management, anti-counterfeiting and access control, supply chain management. The integrated RFID readers can be used both indoors and outdoors and are commonly used in applications such as dock doors, parking lot gates, highway toll stations, livestock tracking, intelligent traffic management, custom clearance, container ports, and automatic weighing.
