"Our goal is to develop a quantum encryption scheme to use between a satellite and the ground, where the keys are generated in orbit," said Vallone. "However, today’s polarization encoders aren’t ideal for use in space because they are unstable, expensive and complex. They can even exhibit side-channels that undermine the security of the protocol."

Unlike the comparatively crude designs on display at the NTSB, today’s FDRs can record thousands of parameters, far more than just the 88 mandated by the Federal Aviation Administration. Some recorders archive voice and data in one unit, saving precious space. Most are mounted in the tail section of an airplane, which is typically the last part to make impact and is therefore most likely to survive a crash.

Satellites and cell towers operate on completely different frequencies and broadcast technologies. YOU CANNOT COMPARE THE TWO TO EACH OTHER, THEY ARE COMPLETELY DIFFERENT.

After a while, we thought we would give Sling a shot, but we recently cancelled it because we don’t really use it. Sling works a lot like cable and satellite used to, where you pull up live broadcasts of TV channels. But, it occurred to me that we don’t channel surf anymore: we’ve become accustomed to finding titles we like and watching them when we want to.

The screen on the Cine 7 is not nearly as glossy as both the Ninja V and Shogun Inferno and that makes it far easier to see outdoors.

3. This illustration shows a spectrum analyzer output display of 128 QAM channels generated by the MAX5882 and MAX5880 combination. The full bandwidth is 1 GHz with a center frequency of 525 MHz. The resolution bandwidth is 1 MHz. You can just make out the 6-MHz channels, 16 per 100-MHz segment.

MagnaCom is a privately held technology company aiming to reinvent the evolution of digital communications, and a recognized technology innovation powerhouse. The company was founded around a whole new, patented modulation technology called WAM™, which can help alleviate the global spectrum congestion and insatiable demand for more bandwidth. This impacts cellular, Wi-Fi, satellite and cable TV, wireless backhaul, cable and DSL modems, long and short haul fiber and numerous other applications. WAM technology applies to carriers, handset manufacturers, and any wired and wireless system OEMs, and communication IC vendors who strive to save spectrum, increase bandwidth, speed and distance or reduce power consumption. With over 100 global patents filed to-date, and nearly 1,000 granted US inventions, MagnaCom is challenging the 40-year dominance of QAM as the modulation of choice for all advanced wired and wireless systems. The company has assembled a world-class team of scientists, executives and advisors from Broadcom, Qualcomm, Motorola Mobility (acquired by Google), Texas Instruments, Intel, ST Microelectronics and Passif Semiconductor (acquired by Apple).

Allergan released its earnings report for the fourth quarter prior to the Wall Street opening bell on Monday, posting adjusted per share earnings of $3.41. That was in comparison to estimates by Wall Street analysts of EPS of $3.34. Revenue at the pharmaceutical company was $4.2 billion, which ended in […]

Weed says the specialized memory modules that go into recorders are not only tough but expensive (a FDR can cost upward of $30,000) and they’re nothing like what you’d find at your local Best Buy. “There’s this perception that memory is cheap,” says Weed, “but memory that endures a survivability sequence is not that cheap, nor small. You don’t bake a USB stick in the oven and expect your vacation pictures to survive.”

This is true also for other systems like GPS (which by the way, every single smart phone uses GPS) and there are FAR fewer satellites providing GPS service than there would be for Starlink.
