Satellite TV for African Villages

startimes_logoAt the end of 2015 Chinese President Xi Jinping announced a cooperative China – Africa plan descriptively titled “Access to Satellite TV for 10,000 African Villages.”

The plan proposes to offer 10,000 villages across 25 countries a package of free services to enable satellite TV. Each village will receive two projector TVs, a 32 inch digital TV, and 20 additional satellite dish systems allowing access. The projectors and digital TV are to be set up in public spaces in the village. To address power shortages, each will also have solar panels and batteries allowing six hours of viewing with no power.

While this initiative doesn’t address internet or broadband issues, it is another example of communications and media extending into resource-poor environments.

The plan is progressing, with completion scheduled for 2019. The implementing firm is StarTimes, a Chinese multimedia company with extensive experience in Africa.

Jio is Conquering India

Reliance-JioPhone-2What happens when the country with the world’s largest population of people without internet access offers free phones and almost free unlimited data?

We’re finding out in India.

In 2016 Reliance Industries, the petrochemical consortium and India’s largest publicly traded company, launched Jio, a telecommunications initiative. Jio is the brainchild of Mukesh Ambani, India’s richest man, who seeks to provide internet access to everyone in India at affordable prices.

Reliance has spent the last few years constructing 200,000 new cell towers and laying 150,000 miles of fiber optic cable to provide fast 4G connectivity across the country, spending $35 billion.

Jio launched its service at the end of 2016, offering free calling, free texting, and six months of free data, after which data charges were about 1/4 industry average. Usage skyrocketed, both in terms of subscribers, now over 200 million, and data usage, now the highest in the world for any company.

In 2017 Jio introduced the “JioPhone”, a hybrid feature phone / smart phone that takes advantage of 4G data speeds. Among other features the phone comes preloaded with 500 streaming TV channels and music in 17 languages. The phone is essentially free: it requires a $23 deposit which is returned with the return of the phone.

Josh Woodward of Google, who has led teams building new web services in India, says that thanks to Jio and the JioPhone, “hundreds of millions of users are now going to come online faster than all the models projected.”

Ambani relates a story that a few years ago he was at home (“home” — 27 stories of rooms complete with helipad) when his daughter came home for break from Yale. “Dad, the internet in our house sucks” she complained. That apparently set in motion the largest, fastest cellular expansion in history.

Ambani’s ambitions apparently haven’t slowed. In July he claimed his network was still only at 20% capacity and that “We are determined to connect everyone and everything, everywhere.”

Viasat

int_vsat_tm_rgb_grdIn the rush towards low earth orbit satellite constellations by SpaceX and others, some traditional satellite broadband providers are receiving limited attention. This may be an oversight. Viasat, which provides broadband services in North America and some other regions, has plans to launch three high capacity geosynchronous satellites between 2019 and 2021 which will bathe the globe in broadband. In their own words, Viasat will “likely become the world’s first global broadband provider.”

The three ViaSat-3 satellites each will have the network capacity comparable to the total of “the approximately 400 commercial communications satellites in space today”.

Viasat hasn’t revealed prices for future services, including in developing countries. Current US broadband services range from $70 to $150 per month depending on bandwidth.

Military Studying Satellite Constellations

darpa logoThe Defense Advanced Research Projects Agency (DARPA) has announced plans to launch 20 test satellites into low earth orbit. The program, called Blackjack, will test prototype spy satellites, aiming for the first 20 to be in orbit by 2021.

One goal of the program is to reduce costs of satellites, from approximately $1 billion for current geosynchronous satellites to about $6 million for individual low earth orbit satellites. A satellite constellation in theory will be both more effective and harder for adversaries to defeat.

The Blackjack program plans to award $117 million in contracts to aerospace companies developing satellite bus technologies. Future awards will be for other design aspects and launch services for the new networks.

New Details about SpaceX Starlink

maxresdefaultThe SpaceX Starlink program seeks to launch over 4,000 low earth orbit satellites to provide broadband coverage across the planet. The project is relatively secretive, so analysts review whatever information comes available.

Earlier this month, a Starlink patent application was published online describing a new low-cost, easy to manufacture approach to phased array antennas. The antenna technology for the network will be critical in allowing fast-moving satellites to communicate effective with ground stations and with each other.

The technical filing also reportedly details a new integrated circuit design used for processing on board communications.

In June Elon Musk tweeted that latency of the two test satellites currently in orbit is a respectable 25 ms. He also said that one more set of revised test satellites will be required before ramping up production.
