Future 4G front-ends enabling smooth vertical handovers

• An overview is given of the most important effects that handover considerations have on the design of multistandard mobile radio transceivers. Focus is on the multitude of design issues and challenges that should be taken into account in the RF/analog front-end part. Topics discussed include the convergence challenge, wireless transceiver design challenge, wireless standards, handover initiation, interworking between GSM and DECT, idle mode issues, possible issues when mobile terminals miss pages, procedure while in active communication in DECT mode, procedure while in active communication in GSM mode, and GSM/WLAN handover.
