MOBILE READER

摘要

The patent aims to embed RFID reader functionality inside a mobile phone, which proposes to use one of the mobile phone' s own RF sources for the forward link to power the UHF tags. This can obviates the need to integrate yet another RF source into the mobile phone, thereby reducing cost and making the integration much simpler. It is proposed to use a TTO RFID air interface protocol such as ISO/IEC18000-64or IP-X. A TTO protocol does not require any modulation of the carrier. TTO RFID tags can respond within about150μs and can transmit an ID in 300μs. The only hardware modification to the mobile phone would be the addition of a small, low cost receiver.
