NSR predicts big gains for VSAT, satellite broadband, backhaul markets by 2021


In the 11th Edition of its Broadband Satellite Markets report, NSR expects that the next decade will be very good for the backhaul, satellite broadband, trunking, and VSAT markets- as in, $9.1 billion worth of good.

The NSR report predicts that there will be more than 5.2 million subscribers of satellite broadband Internet and almost 2.9 million enterprise very small aperture terminal (VSAT) sites installed worldwide by the time 2021 rolls around.

According to NSR, the high-throughput satellites (HTS) launched into orbit above North America are finally showing their effect on 2012's growth curve for satellite broadband Internet access services. NSR believes these services will exert greater influence in America during the next year and a half. In turn, this will boost Western Europe, Latin America, and other regions.

The NSR report also covers the future of the enterprise VSAT market. According to the analysts, the Latin American and Asian markets will exceeded North America and other mature markets in terms of the size of their installed VSAT bases.

NSR further expects that backhaul services and IP trunking will also enjoy significant growth as services transition to provisioning with HTS and O3b capacity. The migration will provide new capacity at a much more affordable price compared to legacy services on the older C- and Ku-bands.

CENI taps SES Broadband Services for connectivity during Burkina Faso parliamentary elections


SES Broadband Services has entered an agreement with the Independent National Elections Committee (CENI) of Burkina Faso for satellite broadband services during the African country's parliamentary elections on December 2, 2012.

The SES affiliate will be teaming up with Newtec, Access Sat, and Unicom. They will provide CENI with satellite equipment and bandwidth for Internet on satellite access, surveillance, and video conferencing services. They will also deploy a satellite communications network that will link together 14,698 polling stations, 45 electoral district offices that serve as the hubs for the stations, and the central election office in Burkina Faso'scapital city of Ouagadougou to ensure the swift and secure communication of ballots.

SES will leverage bandwidth from its satellite at the 5 degrees East orbital slot. Newtec is tasked with providing hardware and hub infrastructure. The VSAT terminals will be installed by Access Sat while Unicom will produce the equipment for the video and LAN network.

According to a statement by Mr. Barthelemy Kéré, the President of CENI, the Committee picked the satellite VSAT platformed offered by SES because it is able to deploy to and transmit electoral data from remote regions. The mobile satellite communications technology will help make sure that the electoral process in Burkina Faso stays transparent. SES and its partners will not only provide fast and reliable data transfer services. They will also deploy biometrics for the voter registration and other innovations.

Asia-Pacific telecom hires Comtech EF for bandwidth compression services

Comtech EF Data Corp. (a subsidiary of Comtech Telecommunications Corp.) secured an order for bandwidth compression services from a telecommunications service provider in Asia-Pacific worth $1.5 million.


Comtech EF's DoubleTalk Carrier-in-Carrier will facilitate the network expansion of the Asia-Pacific service provider. This will allow the latter to open up bandwidth space to deliver new, affordable services to potential customers inrural villages.



Satellite bandwidth prices in Asia are on the rise. In response, service providers looked for technology solutions that can boost throughput and minimize OPEX. Such solutions allow providers to maintain their competitive edge while also leaving bandwidth room to also offer affordable services to cost-conscious customers.

With Comtech EF's help, the unnamed Asia-Pacific service provider will upgrade their DMD50 Universal Satellite Modems with DoubleTalk Carrier-in-Carrier. Using "Adaptive Cancellation" technology patented by Raytheon Applied Signal Technology, the Comtech EF bandwidth compression solution allows a duplex link's transmit and receive carriers to use the same transponder space.

The DoubleTalk upgrade will allow a single transponder to perform the job of two transponders. This saves money for the service provider, which no longer needs to buy new hardware. And DoubleTalk-upgraded transponders become even more effective when combined with advanced forward error correction and modulation techniques that minimize disruption and improve transmissions.

Considered the world's leading company when it comes to satellite bandwidth efficiency and link optimization, Comtech EF Data Corp. provides advanced satellite communication solutions for very-small-aperture terminal (VSAT) systems, bandwidth management, modems, RAN & WAN optimization, and RF products.

SOS: Radio Officers needed in the satcom era?


Is there the possibility that the long-defunct position of radio officer might come back in this age of computerization and satellite communications?

The last time anyone saw a ship's radio officer was probably during the 'Titanic' movie, which got re-released in 3D format quite recently. The ill-fated ship's two radio officers, Jack Phillips and Harold Bride, kept sending emergency and SOS signals up until the radio shack got flooded.

A radio officer, by the way, was an employee of a radio company like Marconi or RCA, who handled radio equipment leased to ships. Also called radio operators, they were considered outsiders by the crew, who called them "Sparks" because their early radio transmitters were crude, low-frequency "spark gap" transmitters.



For decades, radio officer and their transmitters were almost the only means a ship had to maintain communication with shore or other ships. "Sparks" and his brethren handled all communication to and from the ship. He also monitored VHF conversations that were used in bridge-to-bridge communications. He even the use of the ship's radar, because radar used radio pulses. So radar operators had to log their uses in the radio log for the Federal Communications Commission (FCC,) which mandated that all radio communications be recorded.

In fact, a radio officer was so important that regulations forbade a ship from sailing without one. This led to at least one incident of a radio officer who would leave the ship right before it was ready to sail. The mischievous officer would then listen to the ship's crew beg him to return, and wait until he was satisfied with their show of obeisance before returning to his radio shack.

But the proliferation of computers and other electronic technology -especially satellite communications gear- has rendered the radio officer position superfluous. Satellite and broadband communications equipment allow a modern-day ship to easily maintain clear contact with shore. And computer automation could perform the radio officer's many myriad tasks faster and more accurately.

So it was an irony that, during June's GVF Conference on Broadband Maritime in London, a conference participant thought that the defunct position of radio officer still existed. (Perhaps that person could be forgiven; the 3D re-release of 'Titanic' was quite popular.)

Previously, two presenters for major maritime companies had complained that their VSAT systems did not work as advertised. The first presenter, Demetris Makaritis, Fleet Manager, Navigator Gas, said that his VSAT systems didn't work more often than not. He found out that the VSAT systems procured by his company were not compatible with the requirements of his business.

The second presenter, Kaushik Roy, DPA and Company Security Officer for MOL LNG, complained that VSAT was not only unreliable, but also that he couldn't contact the ship if the crew was using the entirety of the ship's VSAT and Fleet Broadband capacity. The solution: Traffic prioritization. The new problem? The MOL LNG crew apparently did not know how to prioritize traffic.

The aforementioned conference participant expressed his curiosity on why the radio officer was not involved in the VSAT purchase. The participant presumed that the radio officer would know the technical requirements for a ship's communication needs. Kuba Szymanski of Intermanager had to inform the participant that radio officers were essentially as extinct as the dinosaurs.

Satellite Markets & Research writer Eliisabeth Tweedie, who covered the GVF Conference on Broadband Maritime, proposed that satcom vendors consider recruiting retired radio officers as advisors. She noted that the conference covered cases where vendors apparently did not understand the unique needs of their customers, who in turn didn't understand the capabilities -and limitations- of satellite communications.

Radio officers  made a living on organizing and ensuring maritime communications during an age when a single missed message might mean "Iceberg, straight ahead!" They can advise vendors and buyers alike about the basic principles of ship-to-ship and ship-to-shore communications, like traffic prioritization. "Sparks" and company might not understand what SkyNet is made of, but they know what those newfangled computers do. That used to be their job; it used to be an art.

VSAT History

The concept of the geostationary orbit was originated by Russian theorist Konstantin Tsiolkovsky, an Imperial Russian and Soviet rocket scientist and pioneer of the astronautic theory. He wrote articles in space travel at the turn of the century. 

In the 1920s, Hermann Oberth and Herman Potocnik, aka Herman Noordung, described an orbit at an altitude of 35,900 kilometers. Its orbital period, or the time for it to make one complete orbit about another object, exactly matched the Earth’s rotational period, making it appear to hover a fixed point on the Earth’s equator. 

Arthur C. Clarke contributed to the understanding of satellites through an article published in Wireless World in October 1945 titled “Extra-Terrestrial Relays: Can Rocket Stations Give Worldwide Radio Coverage?” In this article, Clarke not only determines the orbital characteristics/elements, or the parameters required to uniquely identify a specific orbit, necessary for a geostationary orbit, but also discusses the frequencies and power needed for communications. 

Live satellite communications was developed in the sixties by the National Aeronautics and Space Administration (NASA), named Syncom 1-3. It is transmitted live coverage of the 1964 Olympics in Japan to viewers in the United States and Europe. Soon after, on April 6, 1965, the first commercial satellite was launched into space, Intelsat I, nicknamed Early Bird. 

The first commercial VSATs were C band (6 GHz) receive-only systems by Equatorial Communications using spread spectrum technology. More than 30,000 60 cm antenna systems were sold in the early 1980s. Equatorial later developed a C band (4/6 GHz) two-way system using 1 m x 0.5 m antennas and sold about 10,000 units in 1984-85. 

In 1985, Schlumberger Oilfield Research co-developed the world’s first Ku band (12-14 GHz) VSATs with Hughes Aerospace to provide portable network connectivity for the oil field drilling and exploration units. Ku Band VSATs make up the vast majority of sites in use today for data or telephony applications. The largest VSAT network (more than 12,000 sites) was developed by Spacenet and MCI for the US Postal Service.
