RFID Battery-Free (Passive) Wireless Technology – Advantages & Disadvantages
Advantages of Battery-Free RFID Sensors
Disadvantages of RFID Sensors
- Phase IV invented RFID battery-free sensing and is the recognized world’s expert in the technology. We continue to push the technology to new levels of performance.
- Phase IV is the only wireless sensing company that offers every type of RFID wireless technology including – Low Frequency (LF), High Frequency (HF), Ultra High Frequency (UHF-EPC), Near Field Communication (NFC), and Custom Proprietary Protocol RFID sensors.
For more detailed information on RFID sensors – and the different types of RFID sensors, see the RFID battery-free (passive) systems page.
Battery-Assisted Passive (BAP) RFID Sensors – “The Compromise”
Battery-Assisted Passive (BAP) RFID sensors use a small battery to power the sensor. While not as small as battery-free (passive) RFID sensors, the trade-off is a longer read-range. BAP RFID sensors are ideal in hard-to-reach applications where it’s not possible to get a reading from 3-foot distance. Phase IV has developed a cutting-edge BAP technology with a 10-year life, making our RFID-BAP sensors practically battery-free™. Learn More about our Battery-Assisted Passive RFID Sensors.
Battery-Powered Radio Transmitters (Active) Systems – Advantages & Disadvantages
Advantages of Battery Powered (Active) Wireless Sensors
Disadvantages of Battery Powered (Active) Wireless Sensors
Phase IV offers an easy to use and practical “off the shelf” Wireless Sensor Network (WSN) system with a wide variety of sensors. We also offer some very specialized custom active sensor systems for application that have unique or demanding requirements.
For more detailed information on RFID sensors see the Battery-powered (Active) Wireless Sensors page.
RFID Battery Powered Data Logger Technology – Advantages & Disadvantages
Advantages of RFID Data Loggers
Disadvantages of RFID Data Loggers
Data loggers are devices that periodically take a sensor reading and then store the time-stamped sensor data to on-board memory. At a later time, the data is downloaded to a computer for analysis.
Phase IV offers several data loggers with a wireless RFID interface. A computer is connected to a RFID reader – and the reader communicates with the data logger to download data and control how the data logger collects data (start time, stop time, sampling interval…). The RFID interface is very advantageous over other non-RFID data loggers because no battery power is required for the data logger to transmit data or commands to the PC. Because RFID data loggers do not use any battery power to transmit data, they use batteries that are much much smaller than active wireless data loggers. We leverage our expertise with RFID sensing to create several versions of the world’s smallest sealed data loggers.
