Interesting Facts About Cell Phones

Cell phone (telefone celular) is a wireless, portable, long-range, electronic telephone, which during travel can seamlessly change antenna connections, from one radio reception cell to another radio reception cell, without dropping or losing the ongoing call.

Besides the standard voice function of a telephone, latest cell phones (telefone celular) have features such as SMS for text messages, MMS for multimedia messages, radio, games, internet connectivity for email, browsing, blogging, music (MP3) playback, memo recording, built-in cameras and camcorders, ringtones, personal organizers, Push-to-Talk (PTT), Bluetooth and infrared connectivity, call registers, streaming video, downloading video, video call, and also serve as wireless modems for PCs that can be connected to the Internet.

The power in a cell phone (telefone celular) is obtained from rechargeable batteries, which can be recharged from the mains, a USB port or a cigarette lighter port in an automobile. Nickel Metal Hydride were the most common types of batteries, which due to the "memory effect" (the user can recharge only when the entire battery is drained off) were replaced by Lithium-Ion batteries, which did not suffer from any memory effect.

Cell phones (telefone celular) came into existence because of the invention of hexagonal cells in 1947, for the base stations by Bell Labs engineers at AT&T. This was further developed during the 1960s by Bell Labs. During a call, the channel frequency could not be changed automatically from one cell (base station coverage area) to another cell (base station coverage area) as the person traveled from the area of one cell to the area of another cell. Amos Joel of Bell Labs invented a breakthrough invention and called it as the `call handoff` by which the channel frequency could be changed automatically from one cell to another cell, during the same call, as the mobile user traveled from one cell to another cell. Due to their heavy construction, these phones were used mainly in automobiles.

The first practical cell phone in a non-vehicle setting, and which could be handheld, was invented by Martin Cooper, the General Manager (Communications Division) of Motorola, who made the world`s first handheld cell phone (telefone celular) call on April 3, 1973.

The technology by which the cell phone (telefone celular) works depends on the mobile phone operator; however, all of them use electromagnetic radio waves, which are in touch with a cell site (base station). The base station is composed of several antennas which are mounted on a pole, tower, or building. Cell sites are spread at a distance of 5 to 8 miles (approx. 8 to 13 km) from each other. The low power transceiver from the cell phone transmits the voice and data to the nearest cell site. During movement, the cell phone will "handoff" the information to other cell site. Mobile phone operators use many technologies to maintain the smooth stream of digitized data from the cell phone to the cell site and vice versa.

The wireless telephone technologies are grouped under heads known as generations, starting from zero generation or 0G. The current generation going on is 4G; however, there are old cell phones (telefone celular) that still operate on 1G, 2G, and 3G technologies. The wireless telephone technologies used in each generation are as given below:

0G: PTT, MTS, IMTS, AMTS, OLT, MTD, Autotel/PALM, ARP

1G: NMT, AMPS/TACS/ETACS, Hicap, CDPD, Mobitex, DataTac

2G: GSM, iDEN, D-AMPS, IS-95/cdmaOne, PDC, CSD, PHS, GPRS, HSCSD, WiDEN, CDMA2000 1xRTT/IS-2000, EDGE (EGPRS)

3G: W-CDMA, UMTS (3GSM), FOMA, TD-CDMA/UMTS-TDD, 1xEV-DO/IS-856, TD-SCDMA, GAN (UMA), HSPA, HSDPA, HSUPA, HSPA+, HSOPA

4G : UMB, UMTS Revision 8 (LTE), WiMAX

Frequency bands: SMR, Cellular, PCS

The impact of cell phone (telefone celular) usage on human health has been of considerable worldwide concern. Research studies in Copenhagen, from the Danish Institute of Cancer Epidemiology, the National Cancer Institute, and the Institute of Cancer Research, do not establish any link between cancer and cell phone usage. However, an intergovernmental agency IARC (International Agency for Research on Cancer) forming part of the World Health Organization of the United Nations, undertook a study of 4,500 users and found a statistically significant link between cell phone usage and tumor frequency. Further research is going on.

Cell phone (telefone celular) usage and driving is a common worldwide phenomenon. Some jurisdictions have banned usage of hand-held phones during driving, but allowed the hands-free fashion of cell phone usage while driving. However, studies have found out that the distraction is caused by the conversation itself; hence, both hand-held and hands-free cell phones contribute towards road traffic accidents. Further studies on cell phone usage and driving are going on.

Nokia Corporation is currently the world`s largest manufacturer of cell phones (telefone celular). Other notable cell phone manufacturers, in alphabetical order, are 3G, Audiovox (now UT Starcom), Benefon, BenQ-Siemens, Fujitsu, High Tech Computer Corporation (HTC), Kyocera, LG Mobile, Motorola, NEC, Panasonic (Matsushita Electric), Pantech Curitel, Philips, Research In Motion, Sagem, Samsung, Sanyo, Sharp, Siemens, Sierra Wireless, SK Teletech, Sony Ericsson, T&A Alcatel, Toshiba, and Verizon.

Nintendo Wii + Wii Sports - Good for fitness in children?

The Nintendo Wii it seems, puts pay to the concerns in recent years over the inactivity in children due to their interest in video games consoles. The Wii console really sets itself apart from the rest with its revolutionary motion sensitive controller, which actually requires movement in order to play the games.

The Nintendo Wii comes with the game Wii Sports, which includes tennis, baseball, bowling, golf and boxing. In tennis you will be swinging the remote as if it were a tennis racket and flicking it up to toss the ball into the air with a quick swing to serve. The other Wii Sports games work in a similar way simulating controller movements for like movements onscreen. Boxing however is the only Wii Sports game that uses the nunchuk attachment and is the most physically exhausting game of them all. In order to hit your opponent in the head or body, you will have to aim high or low with your swings.

There are three different activities with each game. In training mode, you will participate in random challenges, after which you will be assigned a fitness age, based on your performance. Sound familiar? The Nintendo DS game, Brain Training comes to mind...a physical version perhaps?

The important thing here is that gamers are becoming more physically active without even realising it - you could say it has a 'kill two birds with one stone' effect, combining video game play with physical activity. Given this 'physical' nature of the Wii, I wouldn't be suprised if parents rushed out to buy the Nintendo Wii just to get their kids off the sofa!

Another great thing about the Nintendo Wii is that it appeals not only to children and teens but to adults too, so its something the whole family can enjoy.

Could the Nintendo Wii revolutionize the way we play video games in the future? It will be interesting to see what Nintendo's competitors come up with next - this could be a tough one to beat!

What You Need to Know about iPod Movies

iPod devices that are equipped with video players must have the movies from their original format converted to one that can be read and played by the iPod movie player system. This means that the movie can either be downloaded from an iPod-friendly site such as the Apple iPod Store or another website dedicated to iPod music and movies, or the user must purchase the appropriate conversion software. Most of the iPod movie conversion systems can convert most types of movie files such as AVI, MPEG, WMV, MOV, MP4, RM, RMVB, H.264, VOB or DivX formats into the MPEG-4 video format that the iPod uses.

In addition to just converting the format, the system must also match the resolution of the iPod movie player. The typical resolution for the iPod display screen is 640 by 480 for optimum viewing and clarity of picture. Without the appropriate software conversion, the picture would be highly distorted. Other resolutions are possible and the software application will usually optimize the file for viewing, selecting the appropriate resolution.

There is also a great program offered by Apple, called QuickTime 7 Pro, that allows you to use home videos and videos that are not professionally made and convert them to play on your iPod, just like an iPod movie that you can download. This is a great way to personalize your iPod video, or send a home movie to a friend or family member.

The process is simple: start by downloading the QuickTime 7 Pro from the Apple website. If you have a Mac computer, simply upload your movie to your computer and click on the title of the movie in the drop down box found on the QuickTime program menu. If you have a PC, upload the movie from the device as per the manuals and then save it in the QuickTime file. Once the movie is selected you will again need to use the drop down box and select the export feature, then click on Movie to iPod and let the computer do the rest.

A scrolling bar will keep you informed of the transfer process and will allow you to see how much more time is required for the transfer to occur. You will then need to synch the iPod with the computer to play the movie the first time, then it will be stored on both your computer and the iPod for future use.

The vast number of iPod movies and the ease of using the conversion software means that more people, even those that are not experts on the computer, can easily keep their favorite movies as well as their favorite songs close at hand on their iPod.

Global Domains International - When it all started

In November 2000, less than nine months after launching .WS to the global Internet community, GDI announced it had sold over 100,000 .WS registrations to customers such as Yahoo!, Intel, Cisco, Dell Computers, and other companies and individuals in more than 180 countries.
As proud and exciting as the beginning of .WS was for Mike and Alan, the future is what excites them most. Just before .WS recorded its first registration, Mike and Alan knew the time had arrived to begin building their business to reflect its quickly changing personality -- from a forty-person shop to that of a multi-national corporate conglomerate. To accomplish this, Mike and Alan focused on surrounding themselves with intelligent people who were filled with enthusiasm, and had the capacity to help launch their business on an international scale. In addition, the .WS founders beefed up their marketing outreach with ad placements in Fortune Magazine, The Wall Street Journal, and USA Today. Additional ads appeared in Major League Baseball’s 2000 World Series program, and thousands of radio spots aired in large urban markets. Mike and Alan also invested heavily in the company’s infrastructure, ensuring that the anticipated volume of registrations would be handled with relative ease and no downtime.
And now, what do Mike and Alan have to say about their "idea," a little more than a year after their harried plane-trip across the Pacific? Mike said, "It’s all about taking a risk and believing in a concept enough to drop everything and make it a reality." Alan concurs. "We are extremely excited about what the next few years have in store for everyone who joins us as we make .WS the global standard for Internet addresses."

Dominate the Rankings on the Search Engines

Today's topic is going to cover a favorite subject of mine, search engines. I am naming this one How to Dominate the Rankings. Must be asking, what in the world makes you an expert on dominating the rankings? What's your credentials. Your right, I have none and I'm no expert. I'm not sure how to dominate anything but my monkey. It's a joke people, just jokes. What I do know is some of my sites are at the top of the rankings and new websites I am working on are rising everyday. Ok Ok, enough already. I think you get the point. I may not be an expert, but I have somewhat of an understanding of how to rank on the 1st or 2nd page. Sooooo. Do I have your attention now. Goood! How do you get your site to the top of the rankings for your keywords. No one really knows the true answer as the search engine world is very complicated. However there are things that you can do to take your website from a site that only you (and maybe some friends) know about to thousands of people knowing. There are 2 factors that you want to consider in your search engine optimization. They are called.

On-page optimization Off-page optimization

Just from the wording you can probably take a good guess at what they are. So I'm not going to go into it. You take it from here. Good luck.. . . Nah, I'm kidding. Let's talk about On-page. On-page optimization is factors that you change on your page. Off-page is factors on other people's websites. What's more important you may ask? Both are important, but off-page is more important than on-page. Back in the hay day of the internet, on-page ruled. But due to spammers and cheats, on-page became less important but still holds some revelance. So make sure you get it right. Today's post is going to focus on on-page for right now. Like my momma always told me, "make sure your backyard is clean before you worry about someone else's" I never understood that when I was young. But it sounded good. I do now though. Anyway, back to the subject. What are factors that you can change on-page to help your rankings. Several. Let's talk about a few here. I think one of the most important ones to change is your Title. Really!! Yes really. You should come up with a good clean title to your website. Not just any Title. The Title of all titles. Your title should be readable to users, such as you and me, but contain YOUR keywords that you want to focus on. Let's look at this in more detail. The Onla Adult Entertainment Site's title is Adult Entertainment Online. Remember above our keywords that we are ranking high with. To name a few

1. adult entertainment 2. entertainment online 3. adult entertainment online

Ooooohhhh. Is it making sense now! Notice anything between the keywords we have and the Title of the page? Alright now on to the next factor meta description and meta keywords. Thing to note: With Google, meta keywords mean nothing. It does not consider it. But most of the others do, so it's good to have in there just in case. I try to optimize my sites for all the SE's, not just one. Word of caution here. Do not go crazy with the keyword. You do not need to put every instance of the keyword or keyphrase in your meta. For instance if your keyphrase is going to be baby momma. You do not need to stuff it with baby momma daddy uncle sister cousin best friend mom. Just put a few key pharses, around 15-20 is a good number to target. Your meta description should touch on your keywords as well. After that, next you want to do is make sure your keywords or phrases appear in your content of your page. Bold or underline one or two just to add importance to it. A side trick that some seo experts say to do is add h1 and h2 tags. Some even go as far as adding h3 or h4 tags. These are called header tags. You add them into your code. Myself personally, I only go up to h2. If your website is full of pictures and banners, search engines cannot see them. Change the alt text of the banner or picture. The alt text is the text that is viewed if a user puts his/her mouse over it. It appears in a little box. Search engines can see that. Put some of your keywords in there. Again, do not spam. I trick I do to not appear to spam is put the keyphrase or keyword and end it with banner or image or picture. For example, keyword baby momma and I have a picture on the site. I would put the alt text for picture to be baby momma picture 1. There are more things to do in which we can speak on it later. What I can tell you is to put your keyword in the search and find the website that is ranking number #1 and copy what they do. Their number #1 for a reason right? So duplicate the format and you should get similiar results. Let's talk about a few things not to do. These will get you banned or penalized.

1. Do not make the keywords or phrases the same color as the background. So to the user, they never see, but the Search engines will. They do not like it and it's consider spammed. If your site does not have the content to fit the keywords and you cannot get creative enough to mix it in so it flows, change up your keywords. Focus on some that you can make flow. But do not do that trick. It's an old trick and SE's are smarter than that. They will know that it's being done and ban you. If your site is doing this now, this is probably why your not ranking well. 2. Keyword spam. This is just repeating the same keyword over and over and over again in your title, meta description and through your page. Again another no no. This will get your site banned from the SE. They see this as spam.

In summary, as I always state in my post, focus on your content. Overall that is the best advice. Set your page up right and focus on the content and the rest should fall in place. With most SE's, when your webpage optimized, it's a waiting game. A little known fact is most websites, probably in the high 80 percentile are not optimized at all to rank well. Your well optimized website will stand out to SE's and move up. Just stay focused on your content. Change up your content regularly, say once every 2-3 weeks, monthly at the worse. This is a good thing as the SE's will see your site as important and keep checking back due to the updated content. We will get into Off-page on another post. I think it needs to be talked about separately. Right now I will let you guys run so you can get working on optimizing your websites. Feel free to share your seo tactics with everyone.

Finding Profitable Keywords For Your Google Adsense Campaign

No doubt that Google Adsense has become the number one player in making money on the internet. The latest claim that I saw advertised was an internet marketer that made over $19,000 in one month. What is their secret? It is simply writing articles and building adsense webpages that use high traffic, or even some traffic, that use profitable keywords. Not just any keywords, profitable keywords. You have to find keywords that your customers use and that your competitors do not use. Their are many tools available and this article will cover just a few of them.

WordTracker is the leading keyword research tool. SEO professionals worldwide use this tool to find profitable keywords. Wordtracker's suggestions are based on over 300 million keywords and phrases that people have used over the previous 90 days. (In other words, there is no "guessing" when you use Wordtracker. Everything is based on the keywords millions of people have actually typed into search engines.)

KeywordDiscovery is also a very popular keyword research tool and is a major competitor to Wordtracker. KeywordDiscovery compiles keyword search statistics from over 180 search engines world wide, to create what they call "the most powerful keyword research tool". It has been noted in a number of reviews that Keyword Discovery returns more words that are relevant than Wordtracker, Yahoo's or Google's suggestion tools.

There are many other tools on the internet that are worth mentioning. They can be used to supplement and verify the profitable keywords that you find using the major keyword tools. They include, the Google search tool, Yahoo Overture, SEO20/20, webconfs website keyword suggestions (you put your competitor's website URL in this one to determine the profitable keywords they are using), and many more.

The SEO20/20 search tool is the most valuable for determining monthly traffic for profitable keywords by search engine. It includes information on the Overture bid prices, total monthly search volume, estimated search volume for Google, Yahoo, MSN, Digital Point (WordTracker), and Nichebot, Google trends, Google Traffic Estimator, Google Suggest, Google Sysnonyms, and Adwords Keyword Tool. It also provides you with links to news searches, directories, blog searches, tag searches, thesaurus, dictionary
