Largescale Macro - Mobile Cellular Backhaul Over Satellite, At Famous Brazilian Festival, Made Possible By Spacebridge


SpaceBridge accomplishes a largescale, urban city size, 2G and 4G mobile cellular backhaul over satellite deployment, to an unserved rural area with no prior cellular coverage.

October 3, 2019

Since the end of July, the Brazilian municipality of Moquem had been the site of the largest religious festival in the state of Goiás. Attracting large crowds of festivalgoers, the site grounds swelled to over 200,000 people.  Culminating in mid-August, in presence of dignitaries, notably the State Governor, Ronaldo Caiado, the I&C Secretary, Wilder Morais, the Mayor of Niquelândia, Fernando Carneiro, and Senator Vanderlan Cardoso, in addition to, Eurico Telles, president of Oi and representatives from the satellite mobile operator RuralWeb and VSAT platform provider SpaceBridge. 

For the first time the city and the festival sites were served with coverage, by mobile cellular COW – Cellular On Wheels. Phone, data and streaming services, whose 100% backbone was provided by a satellite backhauling solution from SpaceBridge, using Ku-Band via Telesat´s Anik G1 satellite. SpaceBridge offered the answer with state-of-the-art Ku-band VSAT stations, outfitted with its WaveSwitch™ technology, operating dynamically in SCPC, A-SCPC and MF-TDMA modes. The collaboration between its satellite technical team, eNodeB terrestrial equipment makers, the mobile operator and the Telesat team, during the whole extent of the event, had allowed the increase of the available bandwidth, adjusting it to the cellular traffic growth, as more people were arriving into the city every day.  

Such flexibility offered the population adequate service, better transmission quality, Internet access for dozens of POS machines, sending photos, videos and texts and voice communications. In events like this, the so-called outgoing traffic, which goes from the mobile stations to the Internet, can even surpass incoming traffic, as the interest of the population is focused on communications through social networks and messaging applications. 

At a given point, the amount of simultaneously verified users reached 3,380, which significantly exceeds the regular traffic that many macro cellular base stations located in large urban centers provide today. For mobile operators, various communication protocols, huge quantity of packets per second, L2 ability, network security, GTP traffic optimization and TCP acceleration are important features required for successful deployment.  SpaceBridge Optimization Embedded Software allows for space segment savings of up to 35%, as well as the use of layer 2 and the ability to prioritize traffic between Control Plane, Management protocol and user traffic with a large amount of packet per second, as some key features of SpaceBridge’s solution that allowed for the mobile operator to fully meet all requirements at this make-shift city.  

“SpaceBridge’s powerful VSAT modems, once again, prove to be the ideal solution for large concentrations of people and for large events, where immediate availability and high quality are crucial factors. In this location with the presence of over 200,000 people during the event, the In-Bound traffic in each eNodeB/VSAT station exceeded 45 Mbps, the total bandwidth was efficiently shared between four stations that operated the sudden unplanned traffic surge that is equal or exceeds the typical peak traffic of some large cities.” – Carlos Xavier, SpaceBridge Brazil
