History Of Cell Phones, Dazzling Facts Every User Should Know

The history of cell phones finds its birth around 1980. A batch of approximately 2000 mobile phones was manufactured in Chicago. The intended customers were given a free phone to see if that type of business would work. They were not the first cell phones manufactured, but they were the first to be mass produced.

The users found it so convenient to be able to quickly and easily call someone from wherever you were at the time. The initial cell phones were wieldy and cumbersome. In addition, they were unsightly as well as expensive.

Today the cell phone industry generates an astronomical $120 billion in revenues. That constitutes an apparent mega monster in anybodys book. Should one or two cell phones go awry, it would be understandable in light of the size of the networks.

However, in most cases you can still rebook a return flight to Hawaii while at the same time make a weather check in Boston. As far as communication is concerned, todays phones are versatile and worth their weight in gold.

It appears as if there is not much behind one mobile call because they are so easy to make. However, just attempting to explain the wireless networks can get perplexing. In point of fact, the wireless networks are a string of radio towers.

Only a few miles separate each tower as they form what looks like a vast grid. The space from one tower to the next is called a cell. The landline telephone network is also connected to the towers. When you call someone on your handset, it searches for a signal from a cell tower.

If your handset cannot find a signal you will not be able to make a call. A major requirement for all cell phones is to have a System Identification Code, SID. It is a unique five digit number. The FCC assigns this number to each carrier.

The SID code is put into your handset after you sign a service contract. Then the phone is activation. When you turn your mobile phone on it searches for a SID on the control channel. Your cell phones inability to retrieve it results in the dreaded no service message being displayed on your phone.

Conversely, should a SID be found, the SID in the handset tries to match up with the SID that was located. When a match is made your cell realizes that it is working from home base.

Should they not match up, your mobile is said to be roaming. The system manager that your phone is roaming in, contacts the manager of your home system. Then your system manager checks its own database to confirm that your SID is valid. Your phone is then tracked as it roams through the various cells. Using someone elses network like that means added costs. The truth of the matter is roaming can hurt your pocket.

A Brief Examination Of Mobile Telephony

The novel technology of mobile telephony has over the last years become the focus point of numerous discussions, both in academia and business environments, due to its tremendously social penetrating abilities. Making the conveyance from telephone's cultural heritage to that of the mobile's augmented reality has generated as much support from various critics, as it has discontent. But the fact still remains that for the privileged developed half of the world, mobiles have become to be viewed as a trendy necessity as well as a social networking tool.

An electronic telecommunications device, the mobile phone or cellular phone, commonly referred to as the "cell," has become one of those personal property items that can fit the criteria of being both a gadget and a tool. Offering its communicating services since the early to mid 1980s, the considerably larger version of the mobile phone was permanently installed in vehicles as car phones. As technological innovations made miniaturization possible, the majority now of mobile phones are easily controlled and operated single-handed. Moreover, the standard voice feature has been enhanced with additional services, like text messaging, camera capabilities, internet browsing and MMS features for sending and receiving photos and video.

Mainly due to their low establishment costs and rapid deployments, mobile phones have since their first introduction spread rapidly throughout the world, outstripping the growth of fixed telephony. From Europe and Australia, to Asia and America, mobile phones are now widely used, with the majority of adults, teenagers and even children now owning at least one model. Packed with widely diverse features, from alarms to teleconference abilities, mobile phones have set the pace to a new type of communication based culture. But the extreme overload of cell phones has not resulted in closer or more genuine communication principles. Still people, in most cultures, base their business deals and personal affiliations to face-to-face interaction, leaving mobile telephony less ground to grow as a meaningful type of communication. After all, it is not that different than having a fixed telephone line; the difference mainly being that you carry that line whenever you might be.

Yet, mobile telephony use has become ubiquitous due to the interoperability factor telecom networks have endorsed and most have allowed it to spread across continents. In fewer than twenty years, mobile phones have indeed gone from being rare and expensive devices mainly used by businesses, to low-cost, trendy and personal items, used by everyone who wishes to have the ability to reach and be reached by others. But, interestingly enough, sociologists have realized that, as any other type of social networking device, mobile users began to develop vastly different practices based on their own cultural biases.

How To Download Ringtones Online Safely

There are lots of websites that offer ringtone downloads. However, mobile users face the risk of contracting a trojan or virus if they download ringtones online. In addition, there are other serious risks involved: hidden charges from downloading a ringtone and the possibility that your credit card information will be hacked by fraudulent individuals.

Those Internet sites that require your credit card information should not be trusted that easily to avoid getting your credit card information stolen. Though there are legitimate sites that offer free download of ringtones, these ringtones are usually single tones only. Also, the choices of mobile users are very limited from these websites.

Mobile users have other options to download ringtones. One, they can do it through the Wireless Application Protocol or WAP function of their mobile phone. The WAP function is designed to provide convenience to mobile users. With just a few strokes of the fingertips, a mobile user can surf the Internet.

Usually, a mobile user is charged per connection time to the WAP Internet. It is more costly than surfing for a ringtone through cable or wi-fi internet connections. The surfing and downloading speed is also slower. The convenience of the mobile Internet, on the other hand, can not be disregarded. Safety from virus and trojan attacks is also offered aside from free browsing when the website of the mobile service provider is accessed.

Two, mobile users also have also the option to download ringtones directly from the kiosks of mobile service providers. Mobile kiosks are available in wireless centers for use by mobile users. These kiosks do not only offer downloads of ringtones; wallpapers, themes and other services can be accessed from these stand-alone customer service machines. If mobile users have no idea of a particular service, a customer service representative is readily available to assist and explain the service.

Mobile users can also download ringtones from other mobile users through the infra-red or bluetooth wireless connection. Infra-red wireless connection is shorter in range compared to bluetooth. Also, infra-red requires necessary alignment of the source mobile phone to the recipient mobile phone for transfer. The bluetooth, on the other hand, is a newer technology that has a wider range and there is no necessary alignment to be done.

As newer functions and capabilities of mobile phones are introduced, we can be assured of more convenience in store for mobile user. However, even if the technology gets more advanced, trojan, virus and hack attacks will never disappear. So, even there are lots of options available for mobile user to be able to download ringtones online, extra caution should be observed at all times.

International Cell Phone Services

If you are one who does a lot of international traveling, then you will want your clients to be able to reach you from wherever you might be in the world. But what are some of the options you have when it comes to maintaining your current level of cell phone services worldwide? Do you have to buy a new plan? Do you have to pay outrageous rates? Just what is available?
First of all, the country where you live is very important when it comes to international cell phone services. Most of the countries have one standard in cellular communications known as Global System for Mobile Communications or GSM. However, the United States did not follow the GSM standard and allowed competing wire carriers to develop their own standards. So, if you are coming from the United States and want to get cell phone coverage in another part of the world with your existing equipment, you probably will not be able to do it.
So let’s get back to our options for international cell phone service. It is important to understand that the key issues to having effective international cell phone service is that you must have a phone that will handle the frequencies plus a service that is compatible within the country you are communicating from. If you have a phone set that handles GSM service, then your phone will be compatible in at least 212 countries worldwide, as far as hardware is concerned. The only other item you will have to be concerned with is the service plan.
The GSM frequencies operate worldwide typically at 900 MHz but more and more the cell phones are operating at 1800 MHz. There are some GSM phone services in the United States and Canada but they work at 1900 and 850 MHz and therefore are incompatible with the rest of the world. That is why more and more we are starting to see tri-band phones being sold that are compatible with both international and North American GSM frequencies. The Nokia 3220 is a good example as it will handle both the 1800 and 1900 MHz frequency bands.
But what about the international cell phone service? If you get one of the tri-band phones you can get a SIM card that can be used in multiple countries. These SIM cards are somewhat like pre-paid phone service. You put the card in your GSM-capable phone and have international roaming coverage from wherever the card is valid.
When choosing an international cell phone SIM card for your GSM phone, there are things you should consider when making a decision on which SIM card to buy. First, what is the initial calling credit (how long before you have to recharge)? Of course you should know the rate structure of both the incoming and outgoing calls. Next you should make sure that your phone and SIM card you are purchasing will be valid for the countries you intend to travel.
Since you are not going to be global roaming with your home cell phone service, you will want to let everyone there know how they can reach you by your new number. You can also change the greeting on the voice mailbox of your regular home cell phone service telling your callers your new access number while you are out of the country.
While you are using SIM cards that will be exchanged or replaced, make sure that you save everything (phone numbers, memos, notes, etc.) into your cell phone handset and not the SIM card. If you save any information on your SIM card, then the information will be unavailable whenever you exchange for a new card in another country.

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), WiMAXFrequency 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.

How To Maximize Your Adsense Earnings

Most webmasters know that Adsense generates a sizeable chunk of advertising income. That is why many of them use it to go after high paying keywords. They even purchase high paying keyword list that are suppose to escalate thier Adsense earnings, build content driven sites and yet fail to make the money they desire. What are they doing wrong?

A major problem is no traffic. No matter how good the information on your site is, if not many people see the site, your dream of making a good income from Adsense will not be realized.

In order to get the traffic one thing you must do is optimize your site navigation. For many this is a new way of thinking.

But stop for a moment and think about how visitors are using your website. After a visitor has landed on a certain page, they have the tendency to click on another page that sounds interesting.

They get there because of the other links that appears on a page that they initially landed on. This is site navigation. It is all about enabling visitors to move about your site. And one way of maximizing your Adsense earnings.

A typical website has menu links on each page. The wording on these links is what grabs a visitor’s attention and gets them to click on one of the links that will take them to another page of that website. Links that have “free’ or “download” are oftentimes good attention-grabbers.

This navigation logic can also be applied to driving traffic to your high paying pages. There are some websites that are getting a lot of traffic from search engines, but have low earnings. The trick is to try and use come cleverly labeled links to get the visitors off that page and navigate them to the higher earning ones. This is one great way of turning real cheap clicks to real dollars.

Before you begin testing if this same style will work for you and you website, you need two pieces tools. Something to track and compare and some high earning pages you want to funnel your site traffic to. An option is to select a few of your frequently visited pages. This is ensuring faster results.

Now, the next thing to do is think of ways to get visitors from the first page to the link that will take them to your high earning pages. Come up with a catchy and unique description for the link. Think of something that people do not get to see everyday. This will trigger their curiosity enough to try and see what that was all about.

You can also use graphics to grab your readers’ attention. There is no limitation to what you can do to make your link stand out. In order to have a successful Adsense site you must do everything legally, ethically and morally possible to achieve that goal. Just be creative. As far as many Adsense advertisers are concerned, there are no written and unwritten laws to follow regarding what they write. Just as long as you do not overstep the guidelines of the search engines you should not have a problem.

Also remember that it is all about location, location and location. Once the perfect attention grabbing description has been achieved, you have to identify the perfect spot on your page to position that descriptive link so that your site visitors will click on it. For more information about which ad formats do the best, check http://www.adsenselady.com.

There is nothing wrong with visiting other websites to see how they are going about maximizing their site navigation. “Hot pages” or “Most read” lists are very common and overly used already. Get to know the ones that many websites are using and do not try to imitate them.

Another way of doing it is to try and use different texts on different pages. That way you will see the ones that work and what does not. Try to mix things around also. Test your ad formats by putting links on top and sometimes on the bottom too, then tracking each to see which format worked best. You will very quickly be able to tell which ones are getting the most clicks and which ones you might want to remove.

Finding the optimal site navigation style requires formatting and testing, then reformatting and testing. Let the testing begin!
