FCC will approve Kepler, LeoSat, Telesat and SpaceX satellites

The FCC will be voting to approve several companies with new non-geostationary satellite constellations. Viasat (California) will only launch 20 medium-Earth-orbit satellites instead of 24 as per their original plan. Kepler will create a new satellite system for the Internet of Things. LeoSat will offer high-speed connectivity for enterprises and underserved communities. Both will be …

Japan’s next generation terahertz communication will push to 400 gigabits per second

Nippon Telephone and Tokyo Institute of Technology have jointly developed an ultra high-speed IC for wireless front-end that operates on a terahertz frequency band, and in the 300 GHz band they have succeeded in developing the world’s fastest 100 gigabit per second wireless transmission data rate. Unused terahertz waves can be applied to high-speed wireless …

FCC Proposed 10 Mbps wireless download speed is Nigeria’s download speed

Under a new FCC proposal, any area able to obtain wireless speeds of at least 10 Mbps down, 1 Mbps would be deemed good enough for American consumers. Under the previous FCC, wireless was deemed important, but not yet anywhere near a suitable replacement for fixed-line broadband, especially in more remote areas where cellular connectivity …

Transmission of video signals 100 times faster than fastest cellular network

Researchers have demonstrated the transmission of two separate video signals through a terahertz multiplexer at a data rate more than 100 times faster than today’s fastest cellular data networks. Multiplexing, the ability to send multiple signals through a single channel, is a fundamental feature of any voice or data communication system. An international research team …

Arecibo seeing unusual signals from 11 light years away at Ross128

The Planetary Habitability Lab at the University of Puerto Rico is conducting a scientific campaign from the Arecibo Observatory to observe red dwarf star with planets. These observations might provide information about the radiation and magnetic environment around these stars or even hint the presence of new sub-stellar objects including planets. So far, they observed …

Boosting interstellar communication to a laser pushed sail probe to multiple megabits per second

Michael Hippke has calculated how to have multi-megabyte communication speeds between a laser pushed sail probe and a telescope at our solar systems gravitational lensing point. Previously Hippke had determined how to use stellar photon pressures of the stellar triple α Cen A, B, and C (Proxima) together with gravity assists to decelerate incoming solar …

Spacex will begin deploying low cost mass produced internet satellites starting in 2019

SpaceX said it plans to launch thousands of satellites on Falcon 9 rockets beginning in 2019 to establish what would one day become a global broadband internet constellation. Patricia Cooper, SpaceX’s vice president of satellite government affairs, told the Senate Committee on Commerce, Science and Transportation that the company is aiming to launch 4,425 small …

Terabit DSL could solve the last mile problem with far less cost

John Cioffi described Terabit DSL (TDSL). It include carrying 50-600 GHz wireless signals through the tiny spaces between individual twisted pairs or the cables that bundle a hundred of them. “We are shooting for a terabit/second over 100 meters, 100 Gbits/s at 300 meters and 10 Gbits/s at 500 meters — all those are 200 …

Dig Once Bill would lower cost of fiber and broadband by up to 90% and has bipartisan support

Broadband Conduit Deployment Act of 2017 is being discussed at the The House Communications Subcommittee. President Donald Trump plans a trillion dollar infrastructure package that will almost certainly include broadband. If the US adopts a “dig once” policy, construction workers would install conduits just about any time they build new roads and sidewalks or upgrade …
