Whom Should I Contact Regarding the Manufacturing of Custom Tags and Readers?
I have seen you mention a maximum read range of 300 feet. Are there any solutions with a longer range? And can some systems be tied into GPS technology, working together to achieve a more accurate and longer range? I assume that anything can be done, but that it would be a cost issue.
An active tag's range can be expanded with repeaters, which receive a signal, amplify it and forward it on to a reader antenna. There are a variety of tags on the market that can be combined with GPS transmitters to allow the tag to be pinpointed when it is outside an interrogator's read range. There are also tags that can communicate with cell towers to transmit sensor data. If you are monitoring the temperature of produce on a truck, for example, the active tag's sensors can be transmitted via the cell network.
