Learn how to use Your Mobile Phone Cell Phone

Life without a cell-phone… how did we survive without them? From a fashion statement, status symbol, luxury to a necessity, the journey of cellular telephones has been one of great technological advancement. But do we, who take these "cells" for granted, ever think of the technology behind it? A cell phone service is based on a simple idea. It is like a two-way radio, turned into a circuit switched telephone network, comparable in functionality to its landline counterpart. We had wireless sets before, used by security, police, organizers etc. but cell phones were not only accessible easily, they were more personal.

	THE CELLULAR TECHNOLOGY	There is a type of low power two-way radio base station, which serves a coverage area, divided into many smaller zones (cells). Telephone handsets continuously search for the closest base station, and hop from base station to base station if the user was on the move. This strategy of replacing one high power base station with many low power base stations distributed throughout the coverage area made it possible to handle far more subscribers, and reduced the power requirements for wireless telephones. Reducing the amount of power needed to carry a conversation through the airwaves, made it possible for manufacturers to produce much smaller phones. While solid state circuitry advances have played an important role in reducing the size and weight of portable phones, the reduction of power requirements eliminated the need for bulky, heavy batteries to power handsets. The first cellular telephone network put to widespread use was an analog system called AMPS. An AMPS is an analog, frequency modulation scheme (the same scheme used in FM radio). At the time cellular was introduced, FM modulation/demodulation circuitry was a commodity product, and so this was the most cost effective way to introduce cellular service. Digital cellular did not become cost effective until the 1990s when DSP based platforms came down in price enough to make it practical to create an all-digital telephone handset. HOW IT WORKS: Scan Channels: A scan for the closest cell site near you is made, so that you can get the strongest signals possible due to your location at the moment. Send Message: The phone then sends a short message to the cell site verifying the MIN, ESN, and the number that you have just entered to call. Assign Channel: After verifying the above information and your number, the base assigns a message to your phone, telling it where the conversation is. Talk: The phone then gets on that channel and begins to ring. A cell phone has become easily accessible today, as it can fit in most pockets. (pun intended!) a decent cell-phone will be available starting Rs. 5000/- and of course, the sky is the limit if you want an expensive model. Another thing to note is that cell phone prices are going down as the market becomes more competitive. Small is in. At least where the cell phones go. The new tiny single-chassis phones are called "candy bar" models, a reference to their shape. Many weigh less than 200 grams, battery included. The familiar squat flip-phones -- those that open like communicators from the old "Star Trek" -- also are ultra-light. Batteries are getting smaller too. New nickel metal hydride (NiMH) batteries are smaller and lighter than the Nickel Cadmium (NiCad) batteries, but often provide about 40 percent less power. The latest batteries are the Lithium Ion (Li-Ion) and the Lithium Polymer batteries, which are of superior quality. The Cellular Telecommunications Industry Association (CTIA) is a standard performance testing association for cell phones. Like an ISI seal, it too has an approval seal.
	WHAT CAN GO WRONG WITH A CELL PHONE	Your cell phone is tailor-made to deal with tough conditions, which come from the fact that it is a mobile service. But nonetheless, the instruments can take only so much abuse, and are susceptible to breaking. If your phone gets wet, or if you dial the numbers with wet hands, and water gets into the buttons and internal corrosion may occur. Make sure your phone is dry, especially when it is switched on. Using a belt-clip or a holster keeps the cell phone firmly in its place, and prevents it from falling off accidentally. Try not to stuff your phone in with all your other worldly possessions, it may cause the glass display screens to crack. Extreme heat can cause damage to the cell phone electronics and the cell phone battery. Extreme cold can also cause a temporary loss of the display screen.
	SAFE USAGE OF CELL PHONES	WHILE DRIVING Do not use the cell phone in heavy traffic. Do not dial while driving, if it is so important, ask someone to call for you. If you are alone, pull over on the side and dial. Use your cell phone for short calls. Be prepared to end your phone call abruptly. Use memory-dialing options. Learn to use your phone without having to look at it. Never take notes while driving. Make sure your phone is easily reachable when driving.
	VARIOUS OPTIONS	Cellular Phone Carrier: The normal subscription system, where you get a monthly bill for all calls made. Prepaid Cellular Phone: You pay for the service in advance, where the amount in your account is debited with per call made. When the account has been used, you have to get a new card. A pre-paid phone service does not require the initial investment as the monthly service. However, the per call cost is more in a pre-paid. Also, benefits like free night-talk, and others are not available. Cellular Phone Accessories: Extra batteries, vehicle antennas, battery chargers / conditioners, battery eliminators, hands free kits, and leather cases, are all the accessories available. Hands Free: An important safety feature that's included with most of today's mobile phones. It permits drivers to use their cellular phone without lifting or holding the handset to their ear. You can speak into your handset by placing it near you during a conversation. Voice Activated Dialing: A feature available only on selected phones and hands-free car kits that permits you to dial numbers by calling them out to your cellular phone, instead of dialing them manually. This function is especially convenient for making calls from your vehicle while driving.
	THINGS YOU CAN DO WITH YOUR CELL PHONES	How to use your phone as a modem: You can go online to send faxes and e-mail using your cellular phone as a wireless "modem" for your laptop. To do this, you'll need a phone that can function as a modem, a cable to connect your phone to your laptop, and a carrier that offers Internet or data options. For cellular phones without a built-in modem, you'll need to purchase a cellular-compatible PC card modem that works with your laptop. You'll also need a compatible cable to connect the card modem in the laptop to your cell phone. Sometimes the PC card and cable are packaged together as a kit i.e. You can click on the Service Plans tab to see which carriers in your market sell that phone. Newer phones have built-in modem capability, so your laptop doesn't need a PC card, but you'll still have to purchase a compatible cable to connect the phone to your laptop's serial port. Getting Web Updates on your phone: Some carriers offer news, stock and sports updates with activation of a Web-messaging option or service plan. Other carriers provide free news updates as long as you subscribe to text-messaging services. When you sign up for these services, carriers require you to establish an account either on their Web site or on a Web site designed to provide your updates. Once you establish an account, you will be able to select and modify your updates, including when you receive them, simply by accessing your account via the Web site. The updates arrive as text messages (also called short messaging service), so your phone needs to support this feature. Depending on the carrier, updates are subject to character limitations ranging from 100 to 150 characters. Alarm Clocks on phones: With most phones, you simply select the alarm option and enter a time. Some alarms will work even when the phone is turned off. Usually, the phone's alarm will sound just like your ringer alert. E-mail and Faxes on your phone: You can also send and receive data/fax documents, access the internet, email accounts and corporate databases whenever you are on the move. All you need is a compatible phone and computer and the connecting accessories (unless you use infrared). Your mobile acts as a phone line. Calls are normally charged at the same rate as voice calls. You can ask for this facility from your phone service, for just a little extra charge. And then, you become truly global! In touch with the world at your fingertips! Screening your calls: A caller ID displays the caller's number on your phone's screen. It is standard with many digital cellular and PCS (Personal Communications Service) carriers. Some callers can't be identified, depending on how their call is routed to you. Locking your Phone: Locking your cell phone is a great way to ensure you're the only one using your handset. Once you activate the lock mode, you must enter a four-digit code on the keypad each time you turn on the phone. This prevents anyone else from making calls or accessing the phone's memory or menu functions. Tracking Battery Strength: Your phone can indicate on its screen when your battery is almost out of power. The indicator can be a battery icon, a "battery low" message or a red light.
	CELLULAR PHONES AND HEALTH HAZARDS	Although no conclusive evidence has been found linking mobile phone exposure to brain cancer, several new studies suggest that the potential threat to health is greater than previously thought. Another cause for concern is the effect on health due to Radio Frequency (RF) exposure. RF can penetrate exposed tissue, is absorbed by the body and produces heat although the body's normal thermo regulating process carries this heat away. According to new WHO (World Health Organisation) guide rules: Mobile phone users should limit their exposure to harmful radio frequencies by cutting the length of calls. Hands-free devices cut exposure by keeping the instrument away from the head and body. Driving cum mobile phone talking should be banned. Mobile phones should not be used in Intensive Care Units of hospitals as they can pose a danger to patients by interfering with the working of pacemakers and defibrillators. People with hearing aids should not use mobile phones. Base stations, which have low powered antennae on their terrace to communicate with cell phones, should not be located near children's schools and playgrounds.
	A TIP	Let your personal phone be personal: Be discreet about giving out your number Only give your number to people you actually know, it's your money you'll be spending when they ring you up.
	TALK SMART	A cell phone should be used as a device for communicating. Your chats can be left for a landline. Use your phone smartly to save on your bills. Buy smart, talk smart, and save money on your cell-phones. Cell phone technology has gone on to make the world smaller, and at your fingertips. Also people can keep in touch and trace each other with much more ease. So go ahead, and keep your date, even if you missed her at the taxi stand. Just talk!!

The Worlds 10 Best Robots Ever

Bipedal robots that can walk up stairs seem flatfooted compared with the running, jumping, and traditional-Japanese-fan-dancing Qrio. Officially, Sony uses its state-of-the-art androids, debuted in 2003, as corporate ambassadors. But the company may one day sell them for entertainment. Works for Beck: The singer recently used all six Qrios in his video for "Hell Yes."

y back in 1495, Leonardo da Vinci designed what was probably the first robot - an automated suit of armor with a windup crank. It could sit up, wave its hands, and maybe even talk. Five hundred years later, engineer Mark Rosheim used the master's schematics to build a working miniaturized version.

Not all NASA robots drive around poking at rocks. This android will one day work alongside people on space stations. Robonaut is the same size and shape as a person in a space suit, so it can handle tasks typically performed by humans - its hands are even better articulated than an astronaut's gloved digits. The fact that it looks like Boba Fett? Lucky coincidence.

Creeped out by bug bots? How about bug bots that can learn? In 1988, Rodney Brooks' lab at MIT created this six-legged walker, which taught itself how to scramble over boards and other obstacles. The secret: Allow each leg to react to the environment independently and you won't need to program every complex step.

Asimo? A pipsqueak. Before Honda's much-hyped biped was touring the world, there was P2, a 6-foot, 462-pound prototype. Unveiled in 1996, P2 possessed most of Asimo's walking skills - including the ability to climb stairs - making it, as Honda puts it "the first self-regulating, two-legged humanoid walking robot."

Think this is a hunk of plastic that won't fetch a tennis ball? Think again. It's actually an advanced piece of robotics that won't fetch a tennis ball. Introduced in 1999, AIBO is one of the most sophisticated toys on the market. It can find its docking station, recognize its owner's face, and respond to voice commands.

Some robots sit in labs for researchers to tinker with. These two bots are on frickin' Mars. Expected to last only three months when they touched down on the Red Planet in January 2004, the rovers are still going strong two years later - each sends back 100 megabits of data a day.

The Stanford Racing Team's autonomous vehicle is a modified Volkswagen Touareg that can scan any terrain and pick out a drivable course to a preset destination. Cup holders optional.

WABOT and WABOT-2 In the '70s, some roboticists were building machines to make Chevettes, but researchers at Tokyo's Waseda University were building bots in man's image. In 1973, they introduced Wabot, the first full-scale programmable android. It had eyes, flailing limbs, and the ability to speak Japanese. The next rev, Wabot 2,

R2-D2 and C-3PO - the Abbott and Costello of space - may be the most popular robots in history, but it's the littler one that really steals the show. Sure, C-3PO could walk and speak 6 million languages, but R2-D2 proved that robots can be emotive without being humanoid and don't need to speak English to communicate.

Suck cash off the Internet like a giant Hoover !

You might not hear about it much, but there are people out there, marketers, who are very quietly making seven figure incomes as affiliates. You'll never be told the names of most of these affiliates. They don't do seminars, they don't write ebooks, and they don't teach anyone how to do what they do. They just quietly go about their business of sucking cash off the Internet with a giant King-Kong sized vacuum.

If you're like me, you want to know whathey know. You want to suck cash off the Internet like a giant Hoover too. So how do we find out what they know?

Kidnap one of them! Hold him hostage 'till he tells us EVERYTHING. If he won't speak, torture him with rap music and force feed him fast food till he bursts. Okay, the jail time might not be too fun.

Here's another idea: We'll CLONE him. We'll make an exact copy of his brain, and then we'll be able to earn six or seven figures with affiliate marketing, too! Sound nuts? Not as nuts as you think!

There is a guy named Chris who is making SEVEN figures with affiliate marketing and Adwords right now. And he's hired a software team to duplicate the process he uses to make this income. His software does what he does, automatically. It allows ordinary people to create extraordinary incomes and in far less time than you and I thought possible!

There is a catch, however. You've got to be disciplined enough to follow the step-by-step instructions. Don't try to "do your own thing." Simply do what the software tells you to do. I know for some of us, that's difficult. We want to plunge in head first on a whim or hunch. But the software is designed to hunt down REAL profit opportunities, not whims or hunches. When it finds one, it alerts you and THEN you jump in and profit big time. You don't need to be brilliant, or even smart. You just need to follow directions. Now, even I can do that!

Skeptical? No worries, you get a full 56 days to decide. If what I say is true, that if you can follow directions, you can make big money with this software. Be sure and check out the proof on the site, $146,706 in 32 days. What if you made just 1% of that to start? And you made maybe 10% of that after a few months? Could that be a wonderful thing?

Universal remote concept reminds us of the all-in-one gadget dream

What if you could control everything in your home with a little handheld gadget? That's what this universal remote by David Chacon got us thinking about, with its roomy screen — a nerve center right in your pocket.

Simply called the Universal Remote, the device would be flash capable so it could display anything from channel listings to more elaborate menus. With a touchscreen, the right frequencies and support from outside companies, the remote would allow you to change your television's volume to turning on the oven or dimming the lights — and companies could create custom graphic user interfaces for a product, too.
