  6. 6. Readers are so much louder than passive tags <ul><li>RFID readers are very loud shouters that can be. You can hear them in large distances. A group of shouters in 100 meter distance you can not understand. Close by you understand one even if somebody else also shouts in 10 meters distance </li></ul><ul><li>RFID readers can coexist in one channel without interfering with each other, if specially separated by just about 10 meters </li></ul><ul><li>Tags are so gentle voices. You hear them only not too far away. You can not understand a whispering tag if a reader shouts close by. </li></ul>© CISC Semiconductor Design+Consulting GmbH | www.cisc.at | CONFIDENTIAL  Separate shouting readers and whispering tags into different parts of spectrum

  14. 14. Benefits of 4 channel plan <ul><li>Multiple interrogators may transmit simultaneously on the same channel. </li></ul><ul><li>Removal of requirement for “listen before talk” provides users with greater certainty of operation. </li></ul><ul><li>Tag response in the adjacent channels significantly improves reading performance. </li></ul><ul><li>Very spectrum efficient - satisfactory operation by a high density of interrogators in a relatively narrow band (i.e. 3 MHz). </li></ul><ul><li>Using appropriate techniques, SRDs can share the same band as RFID. </li></ul>© CISC Semiconductor Design+Consulting GmbH | www.cisc.at | CONFIDENTIAL
