What factors affect the range of the RFID tags?
There are many factors that affect the read range of active tags, such as the height of the reader, operating temperature, humidity, water, and metal barriers. The most controllable factor is the height of the reader above the ground. Typical heights can be up to 30 feet. The higher the reader, the greater the read range. Because of the frequency of active tags, moisture content in the air and temperature do not significantly affect the read range unless operating temperature specifications are exceeded. Factors such as water and metal barriers tend to reduce read ranges. Back to Question List • What is an active tag? Typical characteristics include a one-, or two-way radio transceiver (one-way for ID only, locator tags; two-way for tags with data storage and/or interactive command sets) (e.g., user defined tag database query). These tags may, or may not, have memory (either erasable, programmable, or random access) for storage of user-defined data, and they have a battery, which is us
