FORNEBU (page3): The company had looked at the calendar to the competitor, and hastily convened a mini press conference Thursday afternoon.
It’s not often attend launches of which no one yet can take advantage of, but That is what skjdde Thursday when Telenor unveiled no less than three news on stairs.
The article was first published by side3.
4g speech
We’ve written about technology many times before, but now confirms Telenor that they formally have enabled what in technical terms is called Volta – Voice over LTE – which is a bit cumbersome way of saying voice over 4G network on.
You knew it perhaps from before, but let’s take it formal: 4G network is currently a pure data network, ie a broadband network. You can not actually make calls while on 4G network, but mobile flow ity to GSM or 3G network when you try to call someone with a 4G phone.
This the displacement between the networks is something that takes some time, and you will often find that it takes both 10 and 15 seconds of dialing a number to the caller on the other end.
Volta – or 4G Voice that Telenor calls it – is a technology that nevertheless makes it possible to make calls over the 4G network even though it is really just the data. There is a slightly advanced form of IP telephony, but as a user you do not need to think anything over the technical.
The benefits of this are many. Firstly, it reduces the time it takes from you dial the number until you get through from 10-15 seconds to around two seconds.
It also means that you will do little to use the GSM network for voice, something which provides better sound – and you can surf on your mobile while you’re talking. And on top of this you will no longer need to wait from you hang up a call and you can surf the mobile phone again.
This is also a necessary step for the 3G network being switched completely in 2020.
Voice over wifi
But once you’ve made it possible to carry voice over a pure data networks, leaving you at little longer.
For nearly simultaneously as voice over 4G is activated, it is now possible to call over the wireless network mobile phone is connected. Also this happens without having to use separate applications or custom settings.
In practice this means that if you have bad cell phone coverage at the lodge, but wireless internet, so the mobile phone function usual way if you are connected WiFi.
This will also give mean dough better indoor coverage in many buildings. There are still some large buildings that are struggling with mobile coverage indoors and with “WiFi Tale” as it looked nice being called, you can both make and receive calls while you are connected to WiFi.
– WiFi Voice will initially act as a supplement to speech over the cellular network. Has reduced coverage, the mobile could use the WiFi network to make and receive calls. This will be welcome for our customers, said Telenor’s technical director Magnus Zetterberg.
And to top it all: This will also make it possible to call from abroad at a considerably lower price than the current international prices (regular subscription price).
Telenor says albeit they initially only open for Norwegian wireless network, but the goal is also that you can call from anywhere in the world.
– This will be a huge benefit for customers, especially outside Europe, says Bjørn Ivar Moen, head of mobile division of Telenor.
Telenor’s technical architect Sonam Rani demonstrate Thursday feature, and what impresses most is the short time it takes from pressing the call button and the device at the other end actually get the call.
According to Rani is the security of the conversation safeguarded even if you were to call over an unsecured wireless networks, because the conversation is encrypted in two rounds .
Some uncertainties
For both of these services are still some uncertainties.
Although Telenor now formally has enabled 4G Voice, it does not help you anything anything: Also every single mobile model must be activated online for volts, and Telenor is highly secretive for when the different phones will be unlocked, but says it will happen in the pools.
We assume that the reason Telenor still brag launch now is that Telia Sonera probably going to launch the same next week.
Wifi speech is even greater restrictions. Initially, only the Samsung 6S, iPhone 6 / 6S and Sony Z5 who have support.
Regular 4G could only exploit one of these frequencies simultaneously, even though all three frequencies were available in which you found yourself.
This could in principle lead to for example 2600 MHz frequency was completely overloaded in an area, while capacity in the other two frequencies were completely unused.
You can compare it that everyone uses one field at a road has three lanes in both directions.
4G +, which both Telenor and Netcom brag uncontrollably off about that cell phone can utilize two frequencies simultaneously. It’s primarily about utilizing the total capacity better.
The latest upgrade, which has not been named, allows mobile phone can be connected to all three frequencies simultaneously.
In theory, this makes it possible to get download speeds of 450 Mbps. More interesting is that you do not want unused and blasted capacity simultaneously. Thus you will be able to get more stable high speeds than before.
