What is Cell Phone Radiation?

Radiation is energy travelling through space in the form of waves or particles. There are several different types of radiation present in our surroundings on a day to day basis. Ionizing and Non – Ionizing are the two types of radiation. As per studies, Ionizing radiation is very harmful to human body because Ionizing rays from x-rays and nuclear energy has been proven to cause cancer. Whereas, In mobile phones Non – Ionizing radiation has been used and it doesn't have any negative effect on human bodies. But the speed at which the technology is growing our studies are not. So, what happen is, it has created doubt in many minds that, does this type of radiation is really safe for human health.

Cell Phone Radiation is a Myth or a serious threat to think about:

As I told you in upper section, there are two type of radiation Ionizing and Non – Ionizing. Ionizing radiation may cause serious threat to human beings because exposure to this type of radiation causes cells and genetic matter to mutate or change form. This can lead to various types of cancer, affecting the thyroid, breast, bladder, colon, liver, lung, esophagus, ovaries and stomach.

But there is nothing to worry about because the type of radiation which our cell phone emits is Non – Ionizing, which means it doesn't do much to human beings ( As per evidence says ). Even then many studies say that it may cause serious problem if we spend a good amount of time with our cell phones, so, the question which arises here is: -

1.           What amount of time a man have to spend every day to become a victim of this radiation.
   
   
    2.  Suppose that the daily time limit for using a cell phone is 30 min, means if a person is using a cell phone for 30 min daily, then he will become a victim of radiation. But the question which arise here is what is the minimum period (days) to become a victim to this type of radiation. Means if I am using my cell phone for 30 min daily, then to how many days or years I have to sustain this thing to be a victim of radiation.
   
   
   3.  Suppose that, I am affected by radiation, then the big question which arises here is, by which disease I would suffer ( Tumours ,Memory impairment, Cancer, Brain damage, Foetal damage ). There is no clear evidence for any of them.
   
   
   
   
   
   
   What should we do?
   There is no need to get afraid from this type of radiation because no one have a clear evidence. Many studies says it may effect human brain, memory etc... but there is no clear proof. And most importantly, many of these studies were conducted in Europe and was held nearby 2004. One thing which I want to make clear is the technology or the mobile signals which works in Europe, is very much different from India or any other country.  Another thing is that, the technology which were in use at that time, was much older then what we use today. Since 2004, mobile market and technology have been very much changed and it has pulled the user mobility experience to the next level. Now days mobile phones are much cheaper, powerful, user friendly, and eco-friendly as well. Even then, if some studies are showing this type of stuff, then what we need to do is, to take some precautionary measures because at the end of the day it is for our betterment and safety. But don't take it to seriously because if there is something found wrong in it, your country government will address you.

History of Facebook

Facebook was founded by former-Harvard student Mark Zuckerberg (while at Harvard) who ran it as one of his hobby projects with some financial help from Eduardo Saverin. Within months, Facebook and its core idea spread across the dorm rooms of Harvard where it was very well received. Soon enough, it was extended to Stanford and Yale where, like Harvard, it was widely endorsed.

Before he knew it, Mark Zuckerberg was joined by two other fellow Harvard-students – Dustin Moskovitz and Chris Hughes – to help him grow the site to the next level. Only months later when it was officially a national student network phenomenon, Zuckerberg and Moskovitz dropped out of Harvard to pursue their dreams and run Facebook full time.

But Zuckerberg needed help to grow his little social networking site that could. He would not stop until The Facebook had been installed on all university campuses in America. In September 2004, they secured venture capital from PayPal founder Peter Thiel. The $500,000 investment was a start, but Zuckerberg and friends had big plans for The Facebook. Seeing the potential value in The Facebook, Jim Breyer and Accel Partners ponied up $12.7 million to assist Zuckerberg in the expansion of his virtual empire.

So by October 2004, Zuckerberg had the money, the manpower, and the institutional backing to go global. Betatesting continued on within the American University population for the next year, and in August 2005, The Facebook dropped the “The” and Facebook.com was registered for $200,000. The network opened up, and within months anyone with a valid institutional email address from over 30,000 organizations across the planet were eligible for membership, including high school students, government employees and the corporate community.

History of Google

Google, the leading search engine worldwide, was founded in 1998 by Stanford University graduate students Larry Page and Sergei Brin. Page and Brin had been working together on a search engine they called "BackRub" since early 1996, but with the encouragement of Yahoo! co-founder David Filo, they decided to start a company in 1998 and went looking for investors to back them. Google, Inc. was established on September 7, 1998. The founders hired Craig Silverstein - who was later to become Director of Technology - as their first employee, and started the business in a friend's garage.

In August 1998, thanks to David Cheriton, a Stanford professor, Page and Brin meet Andy Bechtolsheim, founder of Sun Microsystem and working at Cisco.

After an hour, he makes a $100,000 check to “Google Inc.” without knowing the company does not exist yet.  Andy was one of the few to see true potential of what these boys had created. During their presentation to him, Andy said he had to duck out for another meeting and offered to write them a check. The check was for $100,000 and that indeed had got things moving for them. 

In October 1998, Page and Brin convinced a friend to rent a Garage and spare room for $1700/month. They quickly added 8 phone lines, a cable modem and a DSL line. After two months, they were 8 people and they moved again in February 1999. From a first office in a garage good for small team, they moved to 165 University Ave. in Palo Alto after 5 months This is the home of many other startups including Logitech and Paypal.

In September the boys moved into the their workspace in Susan Wojcicki’s garage at 232 Santa Margarita, Menlo Park, CA. They then went on to file for incorporation in California on September 4 1998.  Shortly after completing this important task, the boys went an opened a bank account in the name of Google Inc., their newly established company, and deposited the $100,000 dollar check Andy Bechtolsheim had given them. Shortly after they have established there new business they began hiring employees. There first one was Craig Silverstein, a fellow grad student from Stanford as well.

 Early in 1999 they struck a deal with Sequoia Capitaland Kleiner Perkins for $25 million. In November 1999 Charlie Ayers joined Google as the company’s first  chef.  In April of 2000. Google announced the MentalPlex program, which envisages the software’s ability to read your mind as you visualize the search results you want. In June of 2000, Google partnered with Yahoo! to become their default search provider. Also in June they announced the first billion URL index, making Google become the world’s largest search engine. In September of 2000 they started offering searches in Chinese, Japanese, and Korean , bringing their total number of supported languages to 15. In December 2000 Google toolbar was released.

It is well known that it extremely difficult to keep on being innovative. Google has taken creative approaches: employees work in small teams (3ideally) and are free to use 20% of their working time personal projects that may become future Google Products. Google News, Froogle, Gmail have roots in this 20% time as well as Orkut.

And they do not seem to lose their humor.

What is 2G (Second Generation) mobile Network?

2G refers to second generation wireless telecommunication technology. While its predecessor, 1G, made use of analog radio signals, 2G uses digital radio signals.
2G telecom networks were commercially launched in 1991 on the GSM standard in Finland. The 2G systems were found to be considerably more efficient on the spectrum, allowing far greater mobile phone penetration levels. Moreover, the phone conversations were digitally encrypted. Second generation technologies are either time division multiple access (TDMA) or code division multiple access (CDMA). TDMA allows for the division of signal into time slots. CDMA allocates each user a special code to communicate over a multiplex physical channel. Different TDMA technologies are GSM, PDC, iDEN, iS-136.CDMA technology is IS-95. GSM has its origin from the Group special Mobile, in Europe. GSM (Global system for mobile communication) is the most admired standard of all the mobile technologies. Although this technology originates from the Europe, but now it is used in more than 212 countries in the world. GSM technology was the first one to help establish international roaming. This enabled the mobile subscribers to use their mobile phone connections in many different countries of the world’s is based on digital signals ,unlike 1G technologies which were used to transfer analogue signals. GSM has enabled the users to make use of the short message services (SMS) to any mobile network at any time. SMS is a cheap and easy way to send a message to anyone, other than the voice call or conference. This technology is beneficial to both the network operators and the ultimate users at the same time.

Advantages

• Digital signals require consume less battery power, so it helps mobile batteries to last long
•  Digital coding improves the voice clarity and reduces noise in the line.
• Digital signals are considered environment friendly.
• The use of digital data service assists mobile network operators to introduce short message service over the cellular phones. Digital encryption has provided secrecy and safety to the data and voice calls.
•  The use of 2G technology requires strong digital signals to help mobile phones work. If there is no network coverage in any specific area, digital signals would be weak. 

Disadvantages

• Voice quality is not impressive if compare to Analog Signals
• Making Clone of numbers is not possible, just like Analog.
• Towers availability in the location is also a very important part of Digital Signals.
• If the network is not so good then user may face call drop problems.
• Data loss is also a major problem between the users because there is no dedicated path for data transfer.

What is 3G?

3G refers to the third generation of mobile telephony (that is, cellular) technology. It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.

Advantages of 3G 

High Bandwidth

High bandwith---the measure of transmission capacity---is one of the selling points of 3G. This allows you quick and easy access to all of your favorite online multimedia and Internet tools, just like you were at home on a computer. You can pay bills, book dinner reservations, update social networking pages and check emails, all on-the-go. While the maximum bandwidth for a stationary 3G device---according to Silicon Press---is 2.05 megabytes (MB), when you are moving slowly (such as walking), this drops to 384 kilobytes (KB). When you and your device are moving at high speeds (such as in a car), the maximum bandwidth drops to 128 KB. However, Silicon Press notes that this is still 10 times faster than the maximum bandwidth of moving 2G devices.

Greater Speed

Using 3G tech, you get to appreciate data transmission speed of up to 2 megabytes per second, as long as you have your device in a fixed position. It also provides you high level of connectivity and greater networking, plus noise resistance. The technology has raised the bit rate, allowing service providers to give high speed Internet facilities, higher call volumes and host of the multimedia applications that may be given to their customers. All of the services may be given to the consumers based upon the data amount sent and not upon the time utilized for the service, therefore the service given to customers are cheaper overall.

Getting information

Getting information is one of the best feature of 3G technology. You can also watch the latest news and headlines, getting data like the weather, sports and economic details. You get to acquire the latest scores in an ongoing Cricket match and other favorite sports. The 3G cellular phones with the very advanced feature can feature highlights of popular sports and shows. The improved quality of services and speed of 3G phones can allow you to watch music videos and movie clips with crisp and clear photos, compared to 2.5G technology phones.

Power Usages

·         In addition to being more expensive, 3G handsets also require more power than most 2G models. This extra power requirement can translate to larger batteries, shortage usage periods between recharging and more bulky handsets overall.

What can an Android phone do?

Android phones are highly customisable and as such can be altered to suit your tastes and needs. You can check your Facebook and Twitter profiles through a variety of apps making it ideal for social networking. Through the calendar you can set reminders from your desktop or your phone and on the latest version of Android you can send links to and from your computer and vice versa.

Another neat feature of Android is that it automatically backs up your contacts for you. When you set up an Android phone you’ll need to create a Google Account or sign in with an existing one. Every time you save a number to the address book of your Android phone it will be synced to your Google Account.

The benefit of this is if you lose your phone all of your numbers will be saved. The next time you get an Android phone and sign in with your Google Account, all of your contacts and friends numbers will be displayed in your new phone’s address book.
