Active RFID tags use internal batteries to power their circuits and broadcast singals to a reader. Because these tags contain more hardware than passive RFID tags, they are more expensive. Active tags have increased reading distances and offer advanced integration capabilities with higher cost assets. Broadcasting high frequencies from 850 to 950 MHz, advanced technology active tags can be read as far as 200 meters. Supply chain and logistics professionals can improve the speed, performance and reliability of their operations with active tags that deliver dramatic improvements in range, reliability, battery life, storage capacity and computing capability. Users can automatically identify and track critical assets over much longer ranges, which is critical given the demanding nature of asset tracking and global, mission critical, supply chain logistics.

The majority of active RFID systems deployed to date make use of a transmitting device to send a unique ID number to a receiver or network of receivers. The most commonly used frequencies are 433 MHz, 868 Mhz (EU) and 915 MHz (USA). RFIDENTITY’s software solutions work with the latest available protocols from leading hardware suppliers to transmit tag data—ultimately reducing the length of data transmission and limiting extended run times. Our team of consultants will work with you to identify the right active technology for your application and then develop a custom solution that meets your business needs.

Wi-Fi RFID (2.45 Ghz) leverages your existing IEEE 802.11 infrastructure to implement RTLS systems with unparalleled asset location and tracking characteristics. Increased functionality and reading distances can be achieved by deploying a Wi-Fi solution allowing integration enhancements and increased coverage areas.

Ultra Wide Band or UWB RFID uses frequencies in the microwave broad band spectrum and is available for deployment with RTLS systems. The key advantage of UWB is the very precise locating of a tag within a 3 dimensional space making this an excellent solution for precision location within a 50 meter range.

Over the past 10 years, passive RFID tags have been widely adopted by Fortune 500 companies to reduce cost and increase capacity throughout their supply chain. Passive tags can enhance production efficiency and improve the overall competitiveness of enterprises without adding additional labor cost. UHF passive RFID tags work on the frequency of 860MHz~960MHz and offer the longest read distances available, from 3m to 20m. UHF tags offer higher read rates for production applications where multiple tag identification is necessary. RFIDENTITY will analyze your current flow process and provide the best industry solution for your application.

Low Frequency versus High Frequency RFID Low-Frequency versus High-Frequency RFID. When determining which hardware solution fits your application, it is important to take into consideration several important factors that contribute to product performance, such as passive versus active tags, read range, and signal attenuation. What’s the best technology to deploy in your environment? LF or HF? There is an industry misperception regarding LF technology and many companies promote HF as a more viable solution. Without properly evaluating the application, analyzing the implementation cost and calculating the ROI, picking the right technology can feel overwhelming. Even within LF and HF systems, there are proprietary systems that have better performance characteristics than similar solutions. That’s where RFIDENTITY can help. We work only with a network of top tier hardware providers to ensure that our customers achieve the highest ROI for their investment.

Battery Assisted Passive RFID is a type of RFID that is a semi-passive tag. These are similar to active tags in that they contain a battery, but it only provides power to the tag in response to a signal of the proper frequency. This saves battery power, but allows these tags to work in warehouses or other settings that might preclude bringing scanners in close proximity to tagged items. Instead, a single pulse from a fixed RFID scanner triggers every tag in range, and the battery-boosted responses travels farther than passive RFID signals.
