Singaporean start-up telco Gentay Communications has launched a new mobile voice-over-internet protocol (VoIP) service in the country – dubbed Nanu – as it looks to shake up the market with a promise to give customers free overseas calls and 'eliminate phone bills'. Gentay's new mobile Nanu service uses 80% less bandwidth than Skype, enabling it to provide free international calls – even to non-Nanu users. In an interview with ZDNet, the newcomer's founder and CEO, Martin Nygate, championed its proprietary ultra-low bandwidth technology which he claims offers a distinct advantage over conventional VoIP communications such as Skype, Line and Viber. Mr Nygate said that whilst rival apps operate on peer-to-peer (P2P) networks and can be routed via several points of presence (PoP) before reaching their destination, often resulting in a degraded connection, Nanu uses a 'different architecture that can route calls either through a P2P network or dedicated lines, which the company leases from various telcos worldwide'. Although the CEO declined to provide details of how the technology works, he did say that it was originally developed for ship-to-shore voice calls in the maritime industry, which use lower bandwidth over satellite to function.
