Conventional telephone calls have not undergone major innovations for a long period of time and it seems that thanks to products from other companies, telephone operators are beginning to renew and update themselves. Currently the voice that is transmitted through the telephone lines is subjected to a great compression and that affects its quality, but being able to use higher bandwidths this changes and the transmission speed increases. We will have to wait to see how the world of operators evolves to see this type of innovation as something already established.
When the iPhone 5 was introduced 9 days ago, Phil Schiller came on stage at the Keynote in San Francisco to tell us about the virtues of Apple’s new creation. One of the things he announced was the technology WideBand Audio included in the new iPhone, something he commented on quite a bit but no less interesting. Many people won’t give it any importance but at the level of the phone industry this would be a big step forward . This technology would provide conventional telephone calls with a much higher audio quality than the current one.
Currently the sound quality of phone calls is quite poor at certain times. The codec that is currently used to digitalize voices in phone calls uses a high compression , something that provides us with a metallic voice and even with background noises when having a conversation with another person.
Ultra Wide Band technology is based on using different frequencies to those used by radio, Bluetooth and Wi-Fi so that is able to transmit information more quickly than other technologies . While these are limited to bandwidths of 900 MHz, 2.4 GHz and 5.1 GHz the Wide Band can use bands up to 10.6 GHz wide, as new frequencies have now been legalised. Sharing frequency bands with other devices allows them to have high productivity, but to do so they must be relatively close.
When it was confirmed that 20 operators would support this technology from the day of its launch it was not specified which ones and after the refusal of the US operators to implement this technology, it seems clear that these 20 unknown operators will be in Europe and Asia.
Although this new iPhone model is not the first device to integrate this technology , it is important to mention that given its high success among users, telephone companies are beginning to consider integrating it into their networks, improving them and providing better quality support for the future of telephony.
Personally, I think this is an innovation worth mentioning, since as simple as it may seem, we would notice this so much that once it was implemented it would be like going back to black and white televisions .
