Manufactured by Orbital Sciences in Dulles, Virginia, New Dawn carries C-band and Ku-band transponders at 32.8 degrees East for its Africa area coverage and will deliver wireless backhaul, broadband and media content which are the fastest growing satellite-based applications in Africa.
The system, known as Lofted Comms, uses a communications relay attached to a helium balloon. A tethered mode offers a shorter range of extending communications and allows multiple use of the same balloon and payload, but may not overcome some obstacles.
It its un-tethered mode, the balloon can rise up to 80,000 feet, overcoming obstacles like mountains and even curvature of the Earth, but lasts only as long as winds keep the balloon in the area and affords only one use per balloon and payload.
Normally, Airborne Warning and Control System (AWACS) aircraft would be used to relay communications from the ship. But the balloon system, which was first tested in Kuwait in January 2009, costs less and doesn’t risk additional lives.
In selecting a city, our goal was to find a location where we could build efficiently, make an impact on the community and develop relationships with local government and community organizations. We’ve found this in Kansas City. We’ll be working closely with local organizations including the Kauffman Foundation, KCNext and the University of Kansas Medical Center to help develop the gigabit applications of the future. Pending approval from the city’s Board of Commissioners, we plan to offer service beginning in 2012. We’ll also be looking closely at ways to bring ultra high-speed Internet to other cities across the country.
The population density is 1,181.9 people per square mile with 61,446 housing units at an average density of 494.5/sq mi. The racial makeup of the city is 55.7% White, 30.12% African American, 0.75% Native American, 1.72% Asian, 0.04% Pacific Islander, 8.61% from other races, and 2.99% from two or more races. Hispanic or Latino of any race were 16.78% of the population. Kansas City, Kansas is the home to the GM Fairfax plant, which manufactures the Chevrolet Malibu and the Buick LaCrosse.
National LambdaRail is a 12,000-mile national fiber-optic network owned and operated by the U.S. research and education community, in contrast with Internet2, which is a university and corporate enterprise.
Larry doesn’t share his 10GigE connection – Glimmerglass switches a dedicated 10GigE line directly into his PC – which happens to be an Optiputer, a tightly coupled supercomputer. Hard drive speeds. Shared.
Fire, police and other emergency responders would get $10.7 billion in federal support for a dedicated public service network.
About $5 billion, currently used for rural phone subsidies, would be repurposed to build cell towers and backhaul networks to towns without mobile broadband services.
An additional $3 billion would go to research and development for wireless technologies.
DailyTech has analysis of the Administration’s broadband plan. It’s not a bad plan – if the 700 MHz “D-Block” were shared by the public and first responders. Otherwise, providing another 3% of Americans with broadband, by extending penetration from 95% to 98% (9.2 million people), is going to be very costly, according to critics like House Energy and Commerce Chairman, Fred Upton.
Designed for small business, branch office, and retail locations, it provides a secure primary or backup connection to the internet. In addition to connection options for traditional wired networking solutions like Cable, DSL, or T1, it can use USB or ExpressCard Data Modems to create instant networks anywhere you receive a wireless broadband signal.
Network failover to alternative networks ensures continuous network uptime
Load balancing of multiple wireless and wired data inputs ensures performance
Dual band WiFi broadcast – either 2.4GHz or 5.0GHz
500 MHz MIPS processor platform is designed to provide 100 Mbps performance
3×3 Wi-Fi antenna subsystem provides extended Wi-Fi range
Provides up to 20 concurrent VPN pass-through sessions utilizing IPSec for the highest level of remote security
‘Wi-Fi as WAN’ feature enables the MBR1400 to act as a Wi-Fi repeater or Wi-Fi to Ethernet bridge
Following Oklahoma, Cox will soon launch wireless service in its New England market, which includes Rhode Island and Cox communities in Connecticut and Cleveland, Ohio. Later this year, the company will introduce Cox Wireless in additional markets, bringing its wireless service to more than 50 percent of the Cox footprint.
Cable companies have at least one big advantage: Hanging microcells from overhead cable is lots cheaper than building towers.
The Ruckus ZoneFlex 7761-CM is a strand-mounted dual-band 802.11n access point while the strand-mounted Belair 100SP supports a range of licensed 3G radios, with a migration to LTE, along with dual 802.11n radios.
The SpecNet architecture, developed at Microsoft Research, contains three key components: users or clients, slave servers that comprise laptops/PCs connected to spectrum analyzers, and master servers that manage the slave servers.
Each analyzer would be connected to a server that would issue commands to it via XML remote procedure calls over HTTP, SpecNet fulfills this need by enabling geographically distributed spectrum analyzers to be networked. Furthermore, SpecNet has an API that allows users to build distributed sensing applications like SpectrumCop with relative ease.
The company has received an experimental license from the FCC to test the radio on lands occupied by the Yurok Tribe in the Klamath River region of Northern California. The tribe is the state’s largest with about 5,000 members and its tribal lands cover roughly 63,000 acres of rugged terrain that render other broadband wireless technologies ineffective.
White Spaces utilize unused 6 MHz-wide channels in the television band, compared to Wi-Fi, which uses 20 MHz channels. But multiple adjacent channels may be ganged together when spectrum is available and the signals generally penetrate walls and foliage better.
Microsoft submitted comments and sponsored a white paper (pdf) by Professor Dirk Grunwald of the University of Colorado, Boulder, as a part of their efforts to address the growing challenges of limited spectrum.
Frequencies in the 300-500MHz range are likely to penetrate walls and concrete much better than 1900/2100 Mhz cellular or WiFi signals, but the antennas are much bigger – the size of tv antennas. White spaces may also be used for Smart Meters and in-home communications.
Whether the FCC ruling will launch a new era in broadband remains to be seen.
TV white spaces availability can be found for any location in the US by using the free search tool at Spectrum Bridge’s ShowMyWhiteSpace.com website, or by downloading the company’s free iPhone application.
