Wireless voice over Internet Protocol (VoIP) networks could end up challenging 3G mobile operators' revenues from voice minutes, according to a new report.
While not directly saying operators will be hit, the latest research from Analysys points out the threat of VoIP running over networks based on Wi-Fi, Bluetooth, WiMax and proprietary broadband wireless access technologies - all of which carry voice as another form of data packet.
Moreover, the consultancy notes that many 3G network operators themselves now offer unlimited data bundles and, while VoIP may not match the quality of voice calls over 3G, it could be an attractive option for some end users looking to save money.
Other broadband wireless access technologies that could help the rise of VoIP include Flarion's Flash OFDM and IP Wireless' W-CDMA TDD.
