Integra Telecom adds several layers of security to wireless networks with its recently-introduced VPN Wireless Backup service. The new Integra wireless backup solution leverages a connection to the Verizon Wireless network to ensure connectivity for VPN Solutions Layer-3 and other critical business applications.
VPN Wireless Backup will ensure that business services immediately continue despite network disruptions. If a wireline fails, the router will automatically switch traffic from the wireline connection to the wireless connection. Once the wireline connection is restored, the router will immediately restore connectivity to the wireline connection.
The new Integra wireless backup system offers the IPsec security measure. IPsec maintains secure encryption of network data that passes through a wireless connection.
In addition, VPN Wireless Backup also provides an additional layer of security to mobile backhaul networks with its Cloud Firewall Service. The Integra-designed defends against malware.
Nokia reported a 39 percent year-on-year drop in the number of smartphones it sold in the second quarter, to 10.2 million, while its net loss more than trebled. - Peter Sayer for ARN
Nokia has been struggling financially as it tries to keep up with the smartphone industry currently dominated by Samsung’s mobile devices running on Google’s Android platform, and Apple’s iPhone, which is rumored to release the latest version, iPhone 5, next month. The company faces challenges in its transition to the Windows Phone operating system from the previous Symbian OS. Only in the US has Nokia’s Lumia 900, created to compete with the Android phones and Apple’s mobile devices, has sales been good. Demand for the Lumia phones are still uncertain despite a 2% percent increase in feature phones sold.

Each new gadget brings speculation about what older device it will replace—full-featured laptops supplant desktops, while ever-smarter phones relieve you from carrying a laptop on occasion. But don’t overlook the partnerships that can result.
The “Voyager 1” spacecraft is a 722 kilogram (kg; also known as kilo, the base unit of mass in the International System of Units and is defined as being equal to the mass of the “International Prototype Kilogram” (“IPK”), which is almost exactly equal to the mass of one liter of water)—1,592 lbs (pounds/pound-mass, a unit of mass used in the imperial, United States customary and other systems of measurement)—space probe, a scientific space exploration mission in which a spacecraft leaves Earth and explore space.
In telecommunication, the radio communication system is the transmission of signals through free space by electromagnetic waves with frequencies significantly below visible light, in the radio frequency, from about 4 kHz to 300 GHz through a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. The radio communication system of “Voyager 1” was then designed to be used up to and beyond the limits of the solar system, which consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. This is because the space probe, a scientific space exploration mission in which a spacecraft leaves Earth and explores space, will have an extremely long space flight, a ballistic flight into or through outer space.
The communication system includes a 3.7 meter diameter (in geometry, a diameter of a circle is any straight line segment that passes through the center if the circle and whose endpoints are on the circle) parabolic dish high-gain antenna (HGA), an antenna with a focused, narrow radio wave beam width. It is to send and receive radio waves, a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light, via the three Deep Space Network (DSN) station the Earth; DSN is a worldwide network of large antennas and communication facilities that supports interplanetary spacecraft missions.
In electronic and telecommunications, “modulation” is the process of varying one or more properties of a high-frequency periodic waveform, called the “carrier signal,” with a “modulating signal” which typically contains information to be transmitted. These modulated waves are placed in the S-band, part of the microwave band which is about 13 cm in wavelength (of a sinusoidal wave), which in physics, is the spatial period of the wave (the distance over which the wave repeats) and X-band, a segment of the microwave radio region of the electromagnetic spectrum which is about 3.6 cm in wavelength. It provided a bit rate (sometimes written as “bitrate,” “data rate” or as a variable “R”), or in telecommunications and computing, the number of bits that are conveyed or processed per unit of time, a high as 115.2 kilobits per second when “Voyager 1” was at the distance of Jupiter, the fifth planet from the Sun and the largest planet within the Solar System, from the Earth, and many fewer kilobits per second at larger distances.
When “Voyager 1” is unable to communicate directly with Earth, its digital tape recorder (DTR) can record up to 62,500 kilobytes (kB; a multiple of the unit for digital information) of data for transmission at another time. The length of time needed to send messages to “Voyager 1” or to receive messages on the Earth depends on teg straight-line distance between the two according to the simple equation t = D/c where D is the distance and c is the speed of light in vacuum, a universal physical constant (about 300,000 km/s) importantly in many areas of physics. As noted below at the February 8, 2012 entry under Events, as NASA reported that “Voyager 1” is about 120.06973 astronomical units (1.7962176x1010 km) from the Earth and about 119.70479 astronomical units (1.7907582x1010 km) from the Sun, the communications signal transit time is over 16 hours.
The smartphone age is also bringing with it an era of fierce competition. Apple’s iPhone has been a bestseller but Samsung’s Galaxy series in partnership with the Android OS has equally done well. The battle for smartphone supremacy has indeed reached a fever pitch that now Apple wants a ban on Samsung’s Galaxy S3 in US soil.
