Freedom Technologies, Inc.’s Post

Checkout my latest blog post looking ahead to WRC-27.

The World Radiocommunication Conference (WRC-23) already started, where representatives from different countries and industries will debate and decide on how to allocate the radio frequencies for various purposes, such as communications in space, on Earth, and in between. From what I’ve been reading, a significant challenge for the space industry is the assumption by governments that allocating more spectrum to terrestrial 5G will increase broadband access for their citizens, a common political objective. However, proponents of space technology argue that new satellite technologies could achieve this goal more efficiently. Let’s wait and see the WRC-23 outcomes…

Article on Free Space optical Communication In an era dominated by digital connectivity, free space communication stands as a beacon of limitless potential. This groundbreaking technology transcends the confines of traditional networks, offering a direct line of communication through the void of space. By harnessing radio waves or laser beams, scientists are pushing the boundaries of data transmission, enabling unprecedented speeds and global coverage. From interplanetary missions to Earth-bound applications, free space communication promises to revolutionize how we connect and share information. As we delve deeper into this frontier, humanity is poised to reap the rewards of faster, more reliable communication systems that can bridge the vast expanse of the cosmos.

Look: Sometimes transmitting packets over Low-Earth Orbit satellites is faster (in terms of latency) than user Silica Optical Fibers, as we show in our paper: Round Trip Times (RTTs): Comparing Terrestrial and LEO Satellite Networks presented in 27th Conference on Innovation in Clouds, Internet and Networks (ICIN 2024) The reason is that light travels at 300,000 km/s over the air and only at 200,000 km/s over silica fibers. So sometimes latency is smaller over close LEO satellites than fibers that have to surround mountains, desserts, etc. See more details here: https://lnkd.in/dfRTGzKd

Fraunhofer IIS opens laboratory in space #Radiation, #vacuum, and substantial #temperature #fluctuations: extreme conditions prevail in space, presenting a tough challenge for satellite communications. With the #Fraunhofer On-Board Processor (#FOBP), experiments can be conducted in space to explore whether new technologies are operational under real conditions. The FOBP passed its final tests last week and has begun its service on board the #Heinrich #Hertz #satellite of the #GermanSpaceAgency at the German Aerospace Center (DLR). #Satellitecommunications players are often faced with the fact that higher-performance technologies come into use only once their functionality has also been proven in space. This delays progress and limits the satellite industry’s innovation potential. To remove these obstacles, Fraunhofer IIS has opened the #FOBP, a laboratory in space equipped with a special feature: the satellite’s payload can be controlled from Earth at any time, even at an altitude of 36,000 kilo meters, and reprogrammed for different use cases. “You can think of it like a smartphone that installs updates to meet new demands,” says Rainer Wansch, Head of the RF and SatCom Systems department. The opportunities for the industry to use the experimental platform are just as diverse as satellite communications themselves. Their smooth operation depends on disparate elements coming together to form a seamless transmission chain. Such elements include the components installed in a satellite as well as the modems and antennas that enable communication from the ground. For these individual elements to work together in an optimum fashion, research is underway into various concepts that aim to manage capacity as efficiently as possible. https://lnkd.in/g3c5XwEv #Newstoday #SatEvo #SatelliteEvolutionGroup

This week it is happening a very important conference for the satellite communication future, the World Radiocommunication Conference - WRC-23 The article from Spacenews entitled "Battle of the Bands: What’s at stake for space at WRC-23]" give a good summary of the discussion that will be happening. A example is the dispute of C-band frequency between 5G telecommunications companies and satellite manufactures/operators. Previous WRC was responsible, for example, for the concession of Irridium bandwidth operation and allow the first global covered satellite communication constellation. Decision made on the conference can shape the next years of space business https://lnkd.in/dbutARnP

I am excited to be a part of the CTO roundtable, discussing the future of satcom, at #SATShow in March 2024. Looking forward to a fruitful discussion with industry peers. More information on the session below and at https://lnkd.in/dS_ApTZ5.   Session Name: CTO Roundtable: Re-Defining "Game-Changing" Space Technologies    Session Description: Satellite industry CTOs are constantly planning for the unknown – dedicating research and development resources to systems that support applications and markets that, in some cases, may not even exist for another decade. This discussion brings CTOs from a variety of space companies together to share strategies to stay innovative in a constantly changing environment, where new “game-changing” technologies appear every other week. The group will also explore the role of satellites in delivering a constantly expanding menu of future space applications, views on AI, the expansion of satellite infrastructure in space, exploring new bandwidths, and the impact of increasing interaction with terrestrial networks and consumer devices.

🛰️Satellite links are increasingly considered a viable solution to enable quantum communication over long distances. Yet when does space turn out to be a better route than ground? What does an efficient ground/space quantum network look like? What kind of trade-offs have to be made between space and ground so quantum communication can deliver its full potential? TNO scientists Gustavo Castro do Amaral, Bob Dirks, David Bakker and Yannick Jong published a paper about the possibility to enable quantum internet via space. ''With this paper we would like to start the conversation about quantum internet enabled by space.”, Gustavo explains Read the paper via the link 🔗: https://lnkd.in/eGGvZAKC #QuantumInternet #GlobalQuantumInternet #SpaceInternet #QuantumComputing #QuantumNetworking #QuantumTech #FutureOfInternet #QuantumTechnology #InternetInSpace #QuantumWorld #TNOspace
