There has been one recent trend in the telecommunications industry that’s hard to evade. I am talking about mobile broadband, ideally realized with LTE. During the 2010 spectrum auctions carriers spent billions of Euros for LTE frequencies; Deutsche Telekom alone spent about 1.3 billions in the auction, the entire spectrum auction in Germany amounted to 4.38 billion Euros. Sounds like carriers see a huge potential in mobile broadband and a glance at the smartphone market, which is geared towards high speed mobile internet proves this.

LTE Does Not Support Voice

The whole idea behind LTE seems to be a substitution of fixed-line telephony and DSL. Of course the extreme high bandwidth helps to achieve high quality of everything that’s transmitted. There is however a downside: LTE does not support voice, which is bad news if you want to substitute fixed-line telephony.

Of all discussed ways to integrate voice with LTE, the general consensus is that the IP Multi Media Subsystem (IMS) is the most promising one. Many carriers, that’s the main point against LTE via IMS, haven’t upgraded their networks for IMS. I don’t think that’s a valid argument. They haven’t upgraded their network for LTE either, and in Europe carriers do have IP-based core networks.

Let’s assume carriers generally have an IMS core and use the SIP protocol. Apart from high-speed mobile data transmission, this would enable new kinds of value-added services:

With LTE we could enhance our Virtual PBX with video telephony and video conferencing. You would have your video phonecall on a smartphone over a fixed-line number. Depending on your phone, it would be possible to share files like presentations with the person you’re having a video phonecall with. A combination of Virtual PBX and LTE would revolutionize meetings. know of course that video conferences where you can share files already exist. But you don’t have them on your mobile and not with the integration of internal and external numbers.

Ring Back Tones are another service that would invite you to take advantage of LTE. And again we’re talking about video phonecalls. With our ECT Multi Media Ring Back you can show people who call you a videoclip while they wait for you to pick up the phone. That’s no new solution and we’ve already sold multi media ring back solutions that work in IMS networks. However with LTE you could enhance the quality of the ring back video and tone because you can transmit large amounts of data at very high speed.

What other value-added services could you offer with LTE? Please share your ideas with me.
