Future of satellite communication is about to get an makeover

In disasters, rescuers usually communicate via satellite if the phone and mobile telecommunication are out. But that has drawbacks: Once the data lines are overloaded, the connection disconnects. In addition, there barely are systems available yet for moving vehicles. Fraunhofer researchers have developed a new antenna system which reliably transmits data via satellite with a high-bandwidth and which is suitable for mobile use.

Natural disasters regularly strike the world. As in the case of the tsunami in Japan or the earthquake in Nepal, electricity, and telephone lines are destroyed in this process as well. Usually, mobile communications fail over a large area because the poles are damaged. That is why during disasters, rescue services turn to their own communications technology — mostly over satellite systems. Data or phone calls are sent directly to a satellite in space and, from there, to receiving stations on Earth. As a result, the rescue workers are not dependent on the communications infrastructure on the ground.
Until recently, satellite communication has had its disadvantages. The setting up of a small satellite station in the field takes some time for example. Once built, it cannot be easily moved. Moreover, the connection breaks off when a lot of data has to be transmitted or when a thunderstorm interferes. The satellite antenna has to be aligned very precisely to the satellite — just like in the case of television. It is now virtually impossible to communicate with broadband in a moving car via satellite since the antenna constantly moves out of focus due to the movement of the vehicle, although there are some antennas available that is supposed to improve but not eliminate the problem completely.

Internet users have become accustomed to a connection which is stable and which does not just break off when a lot of data is flowing over the line. If a person watches an HD movie or uses video calling, then, at most, the picture changes. It becomes grainier, more pix elated when the data line is heavily loaded — but rarely does the connection break off completely. The reason is that Internet technology is now designed so that it can control an application like the browser or Skype in such a way that the quality of the image is reduced but the functionality is preserved.

Connection without interruptions or dropouts:

With satellite communications that are not the case today. If the line is overloaded, it breaks off easily.TV viewers know that during storms, instead of their satellite image getting worse little by little, it just disappears suddenly. In other words, satellite communication has so far been lacking a continuous technology that controls the connection quality (like with the Internet) and adapts to the current utilization of the data line. Researchers have changed the data processing so that the data rate changes depending on the situation. For this purpose, a special modem has been developed for the transmission of the data.
“In this way, we achieve a very high bandwidth of several megabits per second,” says Raschke. “Of course, we don’t approach the Gigabit streams of a solid data line, but for satellite communication, it’s a big step.” Thanks to this technology, rescuers in the future will be able to send videos of the local situation and maps quickly, and without the connection breaking off. Just like you are used to from the Internet. And even clear satellite telephone calls without dropouts will be possible.

No central station required:

So far, individual senders can only connect with each other via a central hub. However, the newly developed modem now establishes direct connections. This contributes to data security not least because the transmitter and receiver now make direct contact with each other, and the data stream is no longer running through the hub.

Understanding Network Slicing Technology- A Key Element of 5G

Telecommunication vendors and mobile operators are making the fundamental strides with a specific end goal to prepare for 2020, the year business “5G” systems are required to wind up distinctly a reality. In any case, the industry accord is that 5G systems will be considerably more than quite recently new radio access as these future systems will be a reconciliation of cross-domain systems.

5G frameworks are relied upon to be an inherent approach to empower coherent system cuts, which will permit telecom administrators to give organizes on an administration premise and meet the extensive variety of utilization cases that the 2020 time span is required to request. In a solitary 5G framework, arrange cutting innovation can give availability to savvy meters with a system cut that interfaces “Internet of things” gadgets with a high accessibility and high unwavering quality information merely for administration, with a given idleness, information rate, and security level. In the meantime, the network slicing can give another system high throughput, high information speeds and low latency for an augmented reality benefit.

With network slicing technology, a solitary physical system can be parceled into various virtual systems permitting the administrator to offer ideal support for various sorts of administrations for various sorts of client sections. The key advantage of network slicing technology is it empowers administrators to give an administration premise, which upgrades operational effectiveness while diminishing time-to-market for new administrations.

Network slicing technology can bolster tweaked availability intended to profit numerous enterprises by offering a more intelligent approach to section the system to bolster specific administrations or business fragments. With this innovation, slicing can be advanced by heap qualities including inertness or transfer speed necessities. Since the slicing of the system is secluded from each other in the control and client planes, the client experience of the system slicing will be the same as though it was a physical isolate organize.

Telecom exhibited 5G network slicing technology at SK Telecom’s corporate innovative work focus in Bundang, South Korea. The exhibit highlighted the production of virtual system slicing streamlined for administrations including super multiview and increased reality/virtual reality, monstrous IoT offerings, and venture arrangements.

In 2016, Ericsson and Japanese broadcast communications firm NTT DoCoMo finished a joint evidence of idea of element network slicing technology for 5G center systems. In the PoC, a slicing administration capacity and system slice in light of administration necessities were self-sufficiently made, empowering changing administrations to be conveyed all the while by means of different coherent systems.

Likewise, Huawei and Deutsche Telekom did a joint demo of network slicing technology in DT’s 5G lab situated in Bonn, Germany.

A year ago, ZTE and China Mobile revealed their 5G-situated future system engineering plan idea and network slicing model framework. The network slicing model is intended to make dynamic 5G application situation by means of an unmistakable organization environment, including versatile broadband, IoT, and portable edge figuring.
