Amar G. Bose, the visionary engineer, inventor and billionaire entrepreneur whose namesake company, the Bose Corporation, became synonymous with high-quality audio systems and speakers for home users, auditoriums and automobiles, died on Friday at his home in Wayland, Mass. He was 83.

His death was confirmed by his son, Dr. Vanu G. Bose.

As founder and chairman of the privately held company, Dr. Bose focused relentlessly on acoustic engineering innovation. His speakers, though expensive, earned a reputation for bringing concert-hall-quality audio into the home.

And by refusing to offer stock to the public, Dr. Bose was able to pursue risky long-term research, such as noise-canceling headphones and an innovative suspension system for cars, without the pressures of quarterly earnings announcements.

In a 2004 interview in Popular Science magazine, he said: “I would have been fired a hundred times at a company run by M.B.A.’s. But I never went into business to make money. I went into business so that I could do interesting things that hadn’t been done before.”

With the SoftBank buyout, will Sprint build the mother of all networks?

Before the acquisition, Clearwire was formulating plans for an LTE network that could support theoretical download speeds of 168 Mbps using just 40 MHz of its spectrum. Sprint could not only build such a network, it could build that same network capacity twice or possibly three times over as it optimizes its spectrum for mobile use and takes advantage of forthcoming LTE-Advanced technologies.

The keyword here isn’t speed — though Sprint can certainly build a fast network — it’s capacity. With more capacity Sprint can support more mobile broadband connections and deliver that service at a much lower cost to the consumer.

Sprint has some disadvantages. The 2.5 GHz airwaves aren’t the ideal airwaves for a nationwide network because their high-frequency signals don’t travel as far as the lower frequencies that AT&T and Verizon use. Also, Sprint has to use a variant of LTE called Time Division-LTE (TD-LTE) that no other U.S. operator is using, making it harder to get devices that work on its network.

But Sprint and its partners are solving those problems.

Is the NSA tapping into Service Providers’ fiber?

map

Here is an interesting article alleging that the NSA has physical access to the fiber-optic cables used by internet service providers that extend the internet throughout the world. And they are doing it by forcing the private companies into security agreements.

The agreements, whose main purpose is to secure the U.S. telecommunications networks against foreign spying and other actions that could harm national security, do not authorize surveillance. But they ensure that when U.S. government agencies seek access to the massive amounts of data flowing through their networks, the companies have systems in place to provide it securely, say people familiar with the deals.

Negotiating leverage has come from a seemingly mundane government power: the authority of the Federal Communications Commission to approve cable licenses. In deals involving a foreign company, say people familiar with the process, the FCC has held up approval for many months while the squadron of lawyers dubbed Team Telecom developed security agreements that went beyond what’s required by the laws governing electronic eavesdropping.
