VoIP service for cellphones may not be offered before the end of 2007


A senior executive of Lucent Technologies Inc. reports that most probably VoIP (Voice over Internet Protocol) service for mobile phones won't be offered before the end of 2007. According to him the reason for this is the slow uplink speed, supported by the current networks, which can't ensure quality voice calls. In order to increase the uplink speed GSM operators will have to upgrade their networks with HSUPA (High Speed Uplink Packet Access) technology and CDMA operators – with EV-DO Revision A standard. However, this high-speed technology is not expected to be commercially available before the end of 2007 or the beginning of 2008. Lucent's executive also unveiled that the company is working together with Samsung Electronics to develop a SIP (Session Initiated Protocol) client software, essential for VoIP service for mobile phones.
