DoCoMo is now offering business subscribers a dual-network 3G/VoIP handset that works as a 3G mobile phone, VoIP terminal, or both simultaneously. The N900iL is based on a Linux-based 3G mobile phone software platform developed jointly by NEC and Panasonic. NTT DoCoMo says the N900iL uses its "passage duple" system for dual-network operation. It can operate as a 3G mobile phone under NTT’s W-CDMA 3G network, or as a VoIP phone with SIP control under wireless 802.11b networks. Or, it can be set up for dual-mode operation under both kinds of network simultaneously.
