Where Did Those Cell Phones Come From?
In 1896 Marconi was granted the world’s first patent for a wireless telegraphy system. In 1897 he formed The Wireless Telegraph and Signal Company. During that same year he successfully sent wireless signals a distance of twelve miles.
In 1901 Marconi proved the curve of the earth did not affect the successful sending of wireless waves. He proved it by transmitting signals from Cornwall, England to St. John’s, Newfoundland, which was a distance of over two thousand miles.
Marconi, along with other scientists and researchers, continued to work and do research on wireless transmissions. In 1932 the world’s first microwave radiotelephone link was established between the Pope’s summer home in the small Italian town of Caster Gandolfo and Vatican City, a distance of approximately thirty miles.
The first ship-to-shore radio conversation took place in 1922 from the ship S.S. America, which was 400 miles at sea. Inter-continent telephone communications between the United States and England occurred in the mid 1930’s.
As technology improved, interest in a car phone service developed. The first car phone service that was introduced in 1949 was a mobile service, but the equipment was big and heavy. The phone required a large receiver (about the size of a large piece of luggage). It was placed in the trunk of the vehicle. To talk on the phone, a button had to be pushed. To listen to the other person, the button had to be released. It was similar to using a two-way radio. A person couldn’t talk and listen at the same time. That technology came later.
Phone calls from the first mobile phone service were not direct-dialed. Instead, an operator working for the mobile phone service company answered when the phone was picked up. The operator connected the caller to the phone company operator, who then placed the call. By the early 1960’s the technology had improved, but only slightly. One step in the connection process was eliminated. The phone was able to connect directly to the phone company, saving the caller the step of having to connect to the mobile phone service operator first. The improved service was called “Improved Mobile Telephone Service” or IMTS.
By the early part of the 1980’s the phones had full-duplex capability. This meant a person could listen and talk at the same time. The phones and receivers were still heavy though. And, because the IMTS phones were a type of scanner, it wasn’t unusual for a person to press a channel button on the phone and hear parts of someone else’s conversation.
Technology continued to improve and continues to improve today. Cell phones are very popular. Today they are a truly mobile device and are easy to transport. Some of the cell phones available today only weigh a few ounces. Some of the small cell phones can be tricky to use though because the buttons on them are very small.
Cellular technology continues to improve. In the United States, carriers have been moving from analog technology to digital technology. One big reason the move to digital technology has been made in recent years is because it allows networks to carry more callers at one time. Calls are also more secure on digital networks, but are still far from being totally secure.
Today, people experience fewer dropped calls, and with the expansion of networks, there are getting to be fewer areas where there is no reception at all. And although many younger people are choosing to have cell phone over a land line phone, there are still many people who are not yet willing to give up their land line phones.

Which Way Are Mobile Phone Games Heading?
Aside online games and static game devices like Playstation, mobile games are the next most popular games around now.
The popularity has grown so big that mobile operators are competing against each other by offering their subscribers loads of both free and paid games for their pleasure. Not only mobile operators, cell phone manufacturers are also pre-programming their phones with a variety of games.
The growing interest in mobile gaming is producing a lot of benefits for the mobile industry. The operators are deriving sizable revenue from selling these games, software developers are regularly deriving royalties from phone manufacturers and the manufacturers themselves are cashing in heavily on revenue from subscribers. You will appreciate the level of income in this are if you consider the fact that by the year 2009, there would be 220 million mobile phone game fans in the world.
Now lets delve into the kinds of games we have around:
We have the embedded games that are factory coded into the phones, SMS games that operate by interacting with a SMS server upon which the game resides and browser games that are played online using the cell phones mini browser. Of all these games the cheapest and most popular is the inbuilt ones though the excitement offered by SMS and online games are not a deterrent to people who would spend every dime to get hooked on. The reason is browser games are of multi-media origin and can be compared to the type experienced on Playstation or xbox.
There are several ways to develop mobile games though the most popular language used are C++, Java and Binary Runtime Environment for Wireless (BREW) platform .
Out of these three, Java is the most popular method. The reason is obvious – java is widely supported by the web and supported by all the principal phone manufacturers. Again a medium like J2ME is open source and thus cheap to use as a development medium.
Java as we know it is highly portable across platforms and leaves developers with little worry that their program will not work on certain phones. Programmers choose this language platform because it does not interfere with programs running natively on the phone.
But in reality the future of mobile game development is in MIDP 2.0 API which is a compilation of high end applications that allow developers to come up with sophiscated and highly interactive games for fans. It is fast to use and ensures a stable program after compilation.
It is projected that this program, though futuristic, shall be the standard for mobile game developers for a long time as it exhibits versatility and the quick deployment – qualities programmer love.

Cell Phone Deals, Mobile Phone Plan
Tips And Tricks On How To Get The Best Cell Phone Deals. And While You’re At It, Shop For A Great Mobile Plan Too.
These days, cell phones are offered at standard retail prices across a majority of the stores. So how do you snag a great deal? Here are a few tricks you can use to get some of the best cell phone deals available:
1. Get a great mobile phone plan to go with your cell phone. These days, getting a cell phone plan will automatically net you some great deals.
2. If you already have an account with a particular cell phone carrier, shop at their stores and keep an eye out for certain cell phones that they might be promoting. These cell phones will be on offer and you can get some great deals on them.
3. Look out for smaller retail shops that are having a sale or discount for that week. You’d never know what great cell phone deals you could get, even if it’s from a smaller store or branch.
4. Shopping online is a great way to get some of the best cell phone deals. Mobile phones are cheaper online (even after delivery charge) because you don’t have to pay the seller an expensive dealer fee.
5. Look out for cell phone deals that include a lot of free gifts with the mobile phone. A nifty hands free kit or pouch is always nice to have.
And to get really a good deal on your mobile phone plan, you might want to consider the following:
1. Make sure that voicemail is included in your cell phone plan at no extra cost. Most cell phone carriers provide this feature but there are a few which still charge for voicemail. That’s no deal at all, especially when a majority of cell phone carriers or plans will get you unlimited voicemail options.
2. If you travel a fair bit, then get a regional mobile phone plan. It’s a great cell phone deal because regional plans have the best mixture of minutes and features, with the best prices. An example of a great regional feature would be the ability to make long distance calls for free!
3. For any cell phone plan, make sure the deals include at least 150 anytime minutes. If you feel that you’re going to make more calls than that, then aim for a higher number.

Cell Phone Antenna May Pose Health Hazards
There is growing consensus that cell phone antennas may be harmful to humans due to the huge volume of electromagnetic waves that get concentrated around it during the receipt and placing of calls. This danger is even further aggravated by cellular manufacturers who place the internal antennas close to the earpiece.
Mobile phones are basically radio sets and therefore emit energy radio signals that can penetrate the body and cause harm.
There have been several commissions on the study of the effect of mobile phone on the human body and the most pronounced has been The Stewart Report which suggested that radio waves indeed penetrate human bodies from mobile phone antennas and specially recommended that children who obviously have softer skulls be extra careful and use the device sparingly. The report further went on to state that the brain cells of children are not as fully developed as those of adults and can therefore be at greater risk as they absorb the radiation more than fully hardened adult skulls.
These hazards may exist but cell phones have become part of everyday living like cars and cannot be dispensed with. In the light of this fact, doing away with our phones may not be a practical approach to solving the health hazards issue. Rather we can adopt some habits to mitigate the effects of the radiation.
Children should not use cell phones for long calls. They should sue land lines instead so as to minimize the length of contact with the radiation emitted by the device.
Consumers should buy phones with low specific absorption rate (SAR). Mobile phones should be kept away from the body as much as possible. They can be put in the purse or bag and only brought into contact with the body when there is the need to make or receive a call.
Users should try to keep their conversations short.
If possible, SMS messages can be sent instead of calls so that there is less contact with the body especially around the skull area.
Keep switching between both ears so that one particular ear does not absorb the full brunt of the radiation all the time.
Radiation emission is at the highest when the phone is trying to connect so keep the phone away from the skull till you see the call fully connected.
Weak signal results in higher radiation so avoid making calls in areas where reception is poor as the device will try to boost its power to get you a connection and resultantly bombard you with more radiation.
We cannot do away with cellular devices looking at the convenience they have ushered consumers in. Nevertheless, we can adopt some helpful attitudes to minimize the harmful effects this technology is bringing to mankind.

Cell Phone Accessories - Check Them Out
Accessories such a coat, purse, or shoes can either complete or dress up an outfit. Cell phones have almost as many accessories as Barbie does. Accessories can be practical, ornamental, or just available. In the cell phone world there are practical accessories that help you to operate the phone safely and those that allow you to carry it safely.
Some, like downloadable ring tones, are there for you if you want them. I have put accessories into groups to make them easier to describe. There are operational accessories that include battery chargers. Chargers are phone and model specific so that they are not interchangeable.
Hands free kits can be bought that are easily installed in your vehicle. These will let you talk on the phone and keep your hands on the wheel. The signal between your phone and cell tower can be strengthened with the use of antenna boosters. Where there are weak cell phone signals these are really good.
There are specific batteries from your cell phone’s manufacturer and for your specific cell phone. Until you can recharge your cell phone battery there is an attachment that will your weak battery a boost. There are speaker phone kits. Rather than drive with one hand and hold the phone with other, these attachments let you talk on the phone and keep your hands on the wheel.
Place dashboard mountable holders well within arms reach. There are a number of styles of cases and holders. The eyeglass case and horizontal case are alike. Pocket eyeglass cases are similar to vertical cases. Cell phone holsters can be worn across your shoulder like a policeman or on your belt.
Wear multi-use cases on your arm, your wrist, or your thigh. Not only will these cases hold your cell but they will hold your license and a few dollars. These types of cases will hold your cell, your license, and a few bucks. These cases hold your cell phone, your license, and maybe a few bucks.
Velcro(tm) are generally found on these cases. You can find accessories for your cell that are technical in nature. Internal accessories include downloadable ring tones and games to help you pass the time while you are waiting. These ring tones can include holiday songs, the traditional ring, or The William Tell Overture.
Cell phones are little computers that are internet ready, organizers, calendars, note recorders, and to do lists; they are no longer just phones. They now have phone directories, recordings of missed calls so you can return calls later, and they record the identity of callers.
There are antenna boosters that strengthen signals and radiation shields to reduce radiation exposure. Cell phone accessories include covers and face plates. There are front and back pieces to phone covers.
Face plates, some with designs, go over the keypad and the front of the phone. Cell phone accessories include very cute plush animal covers. They are both functional and cute, and the phone goes in the back of the animal. The animal acts as a cushion for the phone in case its ever dropped.
Prices of cell phone accessories and cell phones can vary. Most accessories are optional and some are simply fun. It is important to remember that not all cell phone accessories are interchangeable. You should learn all about your cell phone and how it operates.
