Boeing's Satellite Internet Project

Larry Press

2,956 satellites orbiting at altitudes of 970, 1,034 and 1,086 km at inclinations of 45°, 55° & 88° (Source).I recently posted updates on the satellite Internet service projects of SpaceX and OneWeb. OneWeb and SpaceX have received a lot of publicity, but there is a third entry in the global satellite Internet race — Boeing.

Boeing has applied for a license to launch a constellation of 2,956 Internet-access satellites orbiting at an altitude of 1,200 km. (In a subsequent amendment, the orbits were lowered to three different levels). They outlined a two phase plan — the first 1,396 satellites would be operating within six years, and another 1,560 would be launched within 12 years as demand justified.

There has also been speculation that Apple may be funding and collaborating with Boeing on satellite Internet-service provision. (If you follow this link, read the comments).

Small cells around Washington DCBoeing will use beam-forming, digital processing and instantaneous handoff between overlapping satellite footprints to generate thousands of narrow spot beams, dividing the Earth's surface into 8-11 km diameter (50-95 km2) cells as illustrated here. Each cell will have 5 GHz bandwidth and, if a cell contains both user terminals and Internet gateways, time-division algorithms will enable frequency re-use to serve both. These are very smart radios!

In reviewing the FCC filings, I was struck by the degree of cooperation between the competitors. When Boeing proposed 1,200 km orbits, OneWeb filed a comment saying that would interfere with their design which also called for 1,200 km orbits. In response, Boeing met with OneWeb and altered their plan, lowering altitudes to 970, 1,082 and 1,030 km.

There were also concerns that waivers Boeing requested might lead to radio interference and SpaceX responded by stating that:

The Commission should encourage systems that facilitate spectrum sharing among licensed users. The waivers Boeing seeks will help to build a sensible regulatory environment for NGSO operations while honoring the goals of the rules at issue.

These companies value engineering as well as business. (Tesla has shared their patents — might SpaceX do the same)?

In researching this post, I came across two other Boeing filings — one for 60 high-altitude satellites (shown here) and another for a low-Earth constellation of 132 satellites and 15 high-altitude satellites. I imagine these smaller constellations will complement the larger constellation somehow but have not been able to learn how they will interact.

Boeing, OneWeb and SpaceX are from different generations. OneWeb and SpaceX are relatively recent startups and Boeing is venerable. The startups may have less legacy overhead and have gotten off to a faster start, but Boeing has been thinking about providing Internet service using a satellite constellation for over twenty years — they were the prime contractor for Teledesic's failed attempt in the late 1990s.

We have three potential global Internet service providers — SpaceX, OneWeb and Apple(?)/Boeing. I hope they all succeed, giving us some competition in the Internet service market. That might one day help current Internet customers who have only one choice for their service provider (like me), but it would surely be a boon for people with no terrestrial Internet access today.
