Close proximity technology TransferJet is evolving. Toshiba has developed an LSI (pictured) that supports TransferJet and is designed specifically for mobile devices. The LSI is sized at just 4.0×4.0× 0.5mm and the smallest of its kind, according to Toshiba.The company says the LSI achieves a receiving sensitivity of -78dBm, outperforming the value of the TransferJet standard itself (-71dBm) and making data transfer between two TransferJet-equipped devices more stable (it actually boasts the industry’s highest sensitivity).
