Google Tech Talks
December 15, 2008

ABSTRACT

Reliable two-way communications are a central component of the effort to modernize the generation, transmission and distribution of electricity. Wireless mesh networks are particularly suited to the task, offering a robust, self-healing architecture that is independent of the grid’s own conductors, capacity that can carry not only meter and sensor data but also support video monitoring of critical infrastructure and broadband communications for line crews, and versatility to support many other applications, including public safety, intelligent transportation systems, and public access. Utilities are increasingly deploying Wi-Fi mesh networks as communications backbones, and in some cases as complete solutions for connectivity all the way down to the meter. This talk will discuss the state of the art in wireless mesh technology, including innovations that came about through building and operating the GoogleWiFi network in Mountain View in collaboration with Google.

Speaker: Cyrus Behroozi
Cyrus Behroozi is Chief Scientist at Tropos Networks. He joined the company in 2000 and developed its first wireless mesh networking hardware. He currently researches network performance in large-scale city-wide Wi-Fi mesh networks, exploring techniques to improve reliabilty, enhance coverage, and increase capacity. Toward these goals, he has developed advanced distributed algorithms for route selection, power and bit rate control, airtime coordination, and channel selection. He is also exploring other licensed and unlicensed wireless technologies that can benefit from a femtocellular mesh architecture and Tropos’ innovations in radio resource management.

Prior to joining Tropos, Mr. Behroozi was in the graduate program in Applied Physics at Harvard University. He was part of the research team that slowed light to 38 miles per hour in a Bose-Einstein condensate and subsequently stopped it outright. He co-authored two articles in Nature on this work.

Mr. Behroozi holds a B.S. in Physics from the California Institute of Technology and an A.M. in Applied Physics from Harvard University.

Introducing Kindle™
Three years ago, we set out to design and build an entirely new class of device—a convenient, portable reading device with the ability to wirelessly download books, blogs, magazines, and newspapers. The result is Amazon Kindle.

We designed Kindle to provide an exceptional reading experience. Thanks to electronic paper, a revolutionary new display technology, reading Kindles screen is as sharp and natural as reading ink on paper—and nothing like the strain and glare of a computer screen. Kindle is also easy on the fingertips. It never becomes hot and is designed for ambidextrous use so both “lefties” and “righties” can read comfortably at any angle for long periods of time.

We wanted Kindle to be completely mobile and simple to use for everyone, so we made it wireless. No PC and no syncing needed. Using the same 3G network as advanced cell phones, we deliver your content using our own wireless delivery system, Amazon Whispernet. Unlike WiFi, youll never need to locate a hotspot. There are no confusing service plans, yearly contracts, or monthly wireless bills—we take care of the hassles so you can just read.

With Whispernet, you can be almost anywhere, think of a book, and get it in one minute. Similarly, your content automatically comes to you. Newspaper subscriptions are delivered wirelessly each morning. Most magazines arrive before they hit newsstands. Havent read the book for tomorrow nights book club? Get it in a minute. Finished your book in the airport? Download the sequel while you board the plane. Whether youre in the mood for something serious or hilarious, lighthearted or studious, Kindle delivers your spontaneous reading choices on demand.

And because we know you can’t judge a book by its cover, Kindle lets you download and read the beginning of books for free. This way, you can try it out—if you like it, simply buy and download with 1-Click, right from your Kindle, and continue reading. Want to try a newspaper as well? All newspaper subscriptions start with a risk-free two-week trial.

Kindles paperback size and expandable memory let you travel light with your library. With the freedom to download what you want, when you want, we hope youll never again find yourself stuck without a great read.

We’re very proud to introduce Amazon Kindle and we hope you like it as much as we do.

chronoel asked:


I was planning to set up a wireless network. The modem was supposed to be connected to the router and the router will be the one to be connected to the switches to distribute the connection to wireless devices. Is this possible?

I just bought a wireless adapter for my xbox 360 on ebay. I connected the adapter to my xbox but it can’t find the network. I have a Netgear Range Max Wireless Router. I have no problem using the network wireless with two MACs. Does anyone have a suggestion if it is the adapter that is bad or I need to configure something else. I would appreciate it.

Thanks in advance.

I know there are a lot of questions about wireless routers but I’ve tried all the advices and it still doesn’t work. I have an Acer Aspire 5630 laptop, and a D-Link wireless router. My broadband internet connection works fine when I connect the laptop with a cable, but it doesn’t detect the wireless connection (the computer’s wireless detecting option is on), I get secure signals from other people in my building, but not from my router. What should I do?

SoCal asked:


Right now, I have a Netgear Wireless Router and my teenage child goes on Myspace. I wanted to make my network more secure so, I wanted to run a non-wireless router into my teenager’s computer and then plug the wireless router into the wired router. How complicated is this?

Or, should I just upgrade to the 802.11n wireless router with a double firewall option.

have some questions about wireless cameras. when running wireless can the other cameras function if the main usb cord or the dsl cord are removed. meaning if you just disconnect the usb will the other cameras on the system still work or does it matter?
