Introduction:
The fourth generation mobile systems (4G) is a conceptual framework and a discussion point to address future needs of a high speed wireless network that can transmit multimedia and data to and from interfaces with wired line backbone network. This is a research item for next-generation wide-area cellular radio where it is designed as a completely fully IP-based integrated system of systems and network of networks. The objective of this generation is that “The user has freedom and flexibility to select any desired service with seam less interoperability, reasonable Quality of Service (QoS) and affordable price, anytime, anywhere.”

4G is an evolution not only to move beyond the limitations and problems of 3G,
But also concentrates on
 Enhance the quality of service
 Increase the bandwidth
 Reduce the cost of the resource.

Objectives:
Since 4G being a speculated technology, there are certain standard objectives to be achieved:

 The future 4G infrastructures will consist of a set of various networks using IP (Internet protocol) as a common protocol so that users will be able to access their needs from different internet based mediums.
 A high network capacity with more simultaneous users per hexagonal cell.
 High data rate of about 100Mbits/sec while the user is in mobility and 1Gbits/sec when the user is relatively stationary.
 Smoother and quicker handoffs to the heterogeneous networks.
 High quality of service for multimedia and data support.
 Seamless connectivity and global roaming across multiple networks at reduced cost.
 Interoperability with the 1G, 2G and 3G systems and existing wireless standards.

Convergence Services:

To achieve all the above criteria there is an essential need for convergence of wired and wireless networks as well as computers, consumer electronics, and communication technology and several other upcoming technologies.
The convergence brings advantages for both the broadcasting service providers and the cellular mobile operators too.

Broadcaster point of view
The broadcasters get an opportunity to introduce interactivity to their unidirectional point to multipoint broadcasting system. A broadband downlink based on Digital Audio Broadcast/ Digital Video Broadcast-Terrestrial and narrow band uplink based on 3G cellular systems

Cellular mobile operator point of view
The cellular mobile operators have an opportunity for providing a complimentary broadband downlink in vehicular environments to support IP based multimedia traffic which is inherently symmetrical.

Thus the next generation mobile systems with all its integrated technologies is to bring about WWWW, The World Wide Wireless Web.

The Book “The Search” by John Battelle speaks about how Google and its rivals brought about the change in business and transformed our culture in to the database of intentions. Initially the author appears to explain about the history of Google, but it's really about the whole search industry.

He then explains about the different implications of search such as how the search engine works, who searches, what is searched, where and why. This takes us inside Google's legendary Page Rank algorithm which is one of the most carefully guarded secrets. One of the distinguishing factors about Google is that it sees the problems of search as one that can be solved mainly through technology, clever algorithms and sheer computational horsepower. He then describes about how the rivals got established in the market.

As Google develops more intriguing and powerful search based applications, he sees search as the key to global commerce bringing buyers and sellers together world wide. He also challenges that in future there would be a completely web based operating system. According to Battelle, future search will be everywhere from phones to cars to our stereos. Anything digital will have the ability to search. The search should be both ubiquitous and personal too. The final part of this book focuses on the potential future directions of Google and its product development. He acknowledges that Google might just be a "digital fantasy train", he describes the possibility that Google will become the centralizing platform for our entire lives. He also conveys that Search is no longer a stand alone application, a useful but impersonal tool to find some thing on a medium called World Wide Web.

Innovation in Home Security

We almost live in a world, which is completely filled up with robbery and law-breaking. We can’t leave home on to a trip or even to have a sound sleep considering the above threats. According to statistics, homes without alarm systems are three times more likely to be broken into than those that do, which necessitates a home security system.
The home security alarm systems these days are more sophisticated and highly marched ones. Home systems are equipped to find fire, burglar and any invasion. The sophistication of home security alarm systems reaches from noisemakers to a more composite systems. There have been many products by many companies, one of the most significant competitors being Honeywell Security and Custom Electronics. The product consists of control panel connected to telephone line, keypad with video monitoring, magnetic contacts, Passive infra red motion detectors, sound sensors, Smoke detectors and wireless keypad.
The control panel has various interlinked detectors and control units. When an unauthorized entry is observed, the home scheme directs a signaling to the local law enforcement federal agency. In some causes like fire, the security alarm scheme will then spark off an alarm to advise the residents and then dials the local fire department. Keypads with video monitors are usually located near the entrances where the resident can view the person and speak to the person at the door step before opening the door and also to enter the passwords to enter home from outside. Magnetic contacts are placed to safeguard windows and doors. A passive infrared motion detector (PIR) is an electronic security device that detects intruders by "sensing" motion or body heat in the area being protected. Speaking sensors are used to record people speaking, glass breaking, roof breaking and other intrusions. Wireless keypads are provided for the sophistication of the customers to control the component at a certain distance. Thus we can secure our valuables in our home and ourselves in a better manner.

Innovation in Automobile Security

Automobiles such as cars, trucks are our locomotives, which should be given equal importance to that of home. Since cars are almost left in parking and we move to our work, home so on, its always easy for the thieves to break in and move them away Protecting our vehicle as well as other valuables in car such as stereo etc. are all excellent reasons to invest in a car security system. The use of these car security systems not only protects our cars from theft but also to sophisticates the customers with various advantages.
There has been an innovative product Identisafe 09 introduced and just now in service by the company United linkers. This product gives 100% theft free solution by a finger print based Car security system. Finger print is one of the unique things that each and every individual possess, so this is used as a safety factor.
Identisafe 09 NXT works on the basis of biometric sensors. The product consists of sensors and their corresponding circuitry installed at dashboard and at doors. These serve for finger print door entry and finger print car ignition. The product also comes up with a wrist watch along with finger print sensors that has a wireless control of the car doors and car ignition. Auto dialer telephone serves as an added advantage, where if an unauthorized person attempt's to start the car or get access inside the car by placing his finger on the fingerprint scanner on the dashboard then the inbuilt dialer system automatically calls mobile phone number. This system has a memory capacity of up to 10 finger prints i.e. this product allows a maximum of ten users. This protection mode can be switched on or off using a deactivation code based on the users wish.

Airport Security:
Airports are the places where lots of people reach for travel, because of this specific reason airports become a focus on terrorist’s plots. Similarly, the high concentration of people on large airliners, the potential high lethality rate of attacks on aircraft, and the ability to use a hijacked airplane as a lethal weapon provide an alluring target for terrorism. So there is a necessity to insure safety of the passengers.
The Federal Aviation Administration (FAA) and Transport Security Administration (TSA) are working on these issues and have imposed strict security procedures at nation’s airport. There are various technologies that are now been implemented that had made a protective environment for the passengers. They are Advanced Technology Check Point X rays, Back Scatter, Biometrics, cast scope, Millimeter wave technology, Threat Image protection and whole body Imaging.
AT represents advanced x-ray technologies that will improve carry-on bag screening and enhance airline passenger security. This provides a clear, high-definition x-ray images that improve TSA security officers' ability to detect potential threat items. Rapiscan 620DV provides both a horizontal and vertical x-ray view of carry-on luggage. These two perpendicular views provide a complete perspective regardless of their orientation inside the system. Automated explosives detection software is also applied to scanned images. Backscatter will be able to detect non-metallic devices and objects, as well as weapons or other harmful objects that a passenger may be carrying on his or her person. Biometrics is used up for individual’s identification using finger print, iris scans. Millimeter Wave Technology, another form of body-imaging technology, uses non-ionizing electromagnetic waves to generate an image based on the energy reflected from the body. Threat image protection provides an enhanced method for the detection of explosives.

Personal Security:
There is always a need for personal security. We can’t be with our dear ones at all times, who can protect us from the external threats. Its always precautionary to know the self defense techniques. But we all cannot get to know those techniques, where today’s innovative technologies have paved a way to protect ourselves by certain products. These products are user friendly, had proved to serve its purpose. People can get these devices and can assure themselves of been secured.
There have been many innovative products in the field of self defense; J & L have come up with certain products that have proved to be better. They are Pepper sprays, stun guns, Personal alarms, Child safety products and Safety lights. Pepper Spray is the perfect self-defense weapon to repel attacks. In addition to causing an attacker pain, pepper spray swells the mucous membranes, which makes breathing difficult, and swells the veins in the eyes, causing the eyes to close. These effects last 20-30 minutes and cause no permanent damage. Pepper Spray is simple to use and easy to conceal.
A cell phone stun gun is a self-defense stun device designed to look like a cellular phone. The concept is simple, attacker or anyone else for that matter, will not be able to detect that the cell phone in our hand is actuality packs thousands of volts of knockdown power for instant self-defense . The non-lethal cell phone stun guns are small enough to fit in our pocket or purse and yet deliver the same results as a full size stun gun. These stun guns have a higher instant incapacitation rate than a 9mm handgun, and are legal to carry in most states. When seconds count, a cell phone stun gun can quickly be put into action and incapacitate an attacker so we can escape unharmed.

Internet Security
The Internet in general is wide open are for mischief. We have had problems with hackers breaking into some large organization, it’s absolutely common for viruses to take over personal machines and do bad things, although usually the bad thing is fairly innocuous. For instance sending out large emails to everyone on your contact list. As Bill Gates emphasis on Microsoft security says “Our products should emphasis security right out of the box”.
One of best solution in the market is McAfee Internet Security Suite with Site Advisor. It is a proactive 10-in-1 always-updating security bundle that protects and adds safety ratings to websites and search engines based on spam. It basically analyzes the results and rates websites in detail for unsafe practices such as spamming, misuse of personal information and browser hijacking. When searching with MSN, Google, Yahoo or Ask.com, Site Advisor provides easy-to understand safety rating by three different color coordinates like red (danger), yellow (use caution) or green (safe) that appear next to search results.
McAfee Internet Security Suite automatically guards the computer e-mails &, IM, downloads, photos, music, videos, important document, online banking and shopping, and privacy from viruses, mass-mailing worms, backdoor Trojans and more. It also automatically cleans or quarantines infections with minimal interruption to your computing.

The book “Generating Buy-In” by Mark S Walton is a book on mastering the language of leadership. Leaders know how to paint a “big picture” that generates action by tapping into people’s emotions. He also conveys that leaders are the persons who knew how to ask for a commitment and inspire their listeners to take steps toward the goal.

Mark conveys that however well positioned, intelligent we may be, we all need some body to buy in. Buy in means understanding, commitment and action in support of our goals. Followers need not take our lead but they should buy what we sell, accept what we say. There are different step by step processes explained in the book to achieve this.

He strongly emphasizes that strategic stories of a positive future have been the most powerful language of buy-in and the most effective way to influence the human mind is to communicate a story.
He also conveys that strategic stories provide us a framework to fill the gap between the future we want and future our audience or customer wants. Then he explains how to develop a strategic story with setting up a generating buy in goal as initial process. Goal is followed by three processes, they are establishing a strategic story line, develop the story line with audience in mind and call for audience actions. So he explains with dozens of examples of individuals who excelled at persuading people to believe, do or buy from Abraham Lincoln to John Welch. Thus he speaks the language of buy in with great personalities to mold powerful thought and emotion in our listeners. In the final part he speaks about applying this language in our life to achieve our goal, what ever the goal might be.

In our day today life we plan a lot, but our transformation ratio of planning to execution has always been less. The book Execution by Bossidy and Charan explains the importance and the process of execution.

This is a book that inspires action. The ideas are relevant for anyone who wants to succeed in an organizational environment, whether it is educational, nonprofit, or corporate services. By focusing on execution and framing it as a discipline, the authors explains us how to tackle the source of so many organizational problems that often go unnoticed and unattended.

One of the important aspects of this book is that it can be utilized for all organizational levels. Bossidy and Charan offer advice and guidance that can be used effectively by anyone in any circumstances that require things to get done in a well established timely manner. Leading for execution does not simply involve following a set of guidelines but on the contrary, it is a way of doing things that calls for a leader to be deeply and passionately engaged in your organization. It is a way of leading that is assertive in getting others to bridge the gap between understanding what should be done and actually following through with the tasks. It is a straightforward idea that none of us takes care or overlook too often.

To illustrate these points, the authors convey the stories of leaders with strong character, intelligence, and vision, with which they achieved success for their corresponding organizations. The authors highlight the importance of analytical thinking in transforming conceptual ideas into real life success.

The format and style of the book are of purpose getting readers to understand why execution is essential, providing examples of how to create the discipline of execution, and showing how to put the principles discussed into practice. This is one of the book with which I was inspired a lot. I would prefer that you all should read this book.

The book “China Inc.” by Ted C. Fishman speaks about the world’s most rapidly changing large economy China. The word “Made in China” is as ubiquitous as money. No country has ever before made a better run at climbing every step of economic development all at once.

China is currently the largest maker of toys, clothing, and consumer electronics, and is swiftly moving up the ladder of technology in car production, computer manufacturing, biotechnology, aerospace, telecommunications, and other sectors. These products are known for their low cost and high-tech factories. China is the place where the world is investing and it is considered because of the cheapest work force but it is not so.

He also speaks about how China as an enormous country once hobbled by poverty and Communist ideology came to be the supercharged center of global capitalism. He then goes about how the developments were achieved from basic food items to high power engines. Since due its higher population consumption was so high that products were produced at surplus. Due to this, lower price year after year with a world class speed and strength had been achieved for these products.

Fishman presents a flood of facts, figures, forecasts, and anecdotes and examines the implications of this unprecedented growth for China, the U.S., and the rest of the world. This in turn Challenges America and rest of the World. Statistics says that one third of china’s production cost was put in by foreign investors. Not only is the gadget industry, China also one of the leading countries in wireless technologies, education and so on. He also says that China had kicked the American Asian foot print. Fishman asserts, China, Inc. is a brisk and informative look at why so many American corporations, and American jobs, are heading towards China.
