Using VoIP With Interoperable Networks
Days of Single Networks Are over
Recent technological advances have demonstrated the feasibility of moving a VoIP call from one network to the other while it is still in progress without any noticeable interruption. This has always been possible but it was never fully developed to its true potential. The reason of course is simple. Traditional telecom companies and the hardware manufacturers had no reason whatsoever to develop such a feature and every incentive not to. But one way or the other, we make progress. Other innovative companies such as Republic Wireless have made no secret of the fact that they plan to revolutionize the mobile industry by creating phones which seamlessly operate on and move between voice and data networks.
Today we heard about Qualcomm and Ericsson demonstrating the first handoff between LTE technology and CDMA. This is significant for many reasons. For one, it means that 3G and 4G networks can survive side-by-side and allow a gradual phasing out of the former in favor of the latter. It also means that major telecom companies and hardware manufacturers are coming to the realization that the multinetwork system is inevitable. This can only be good for VoIP consumers who're eagerly looking forward to fast 4G network speeds for reliable voice connections.
More Networks Need to Be Added
The ideal situation would be when a particular call takes place over whichever network is most convenient, or cheap, or reliable – depending on the preferences of the customer. For example, a person at home need not use either the cellular network, or the wireless data network for making a call because they have free Wi-Fi. The phone has to be smart enough to understand the demands of battery life and be capable of switching off radio receivers that are unnecessary.
So far, voice over LTE has been elusive because LTE coverage is still highly restricted. This means that the customer who moved out of the coverage area is left in the lurch. The ability to seamlessly transfer between an LTE network and any other will bring a tremendous amount of confidence to VoIP users. So what we need as of now for the next few years at least, is the phone which is capable of integrating Wi-Fi, LTE as well as 3G and CDMA by being able to switch off the relevant radio receivers when there is no network coverage. This will protect battery life which is all important in a smartphone.
This is just the tip of the iceberg. This new feature will be likely to be integrated in the latest models of Android and the iPhone.
