Camera Cell Phones

noreply@blogger.com (Hopefully Useful) — Mon, 09 Jun 2008 05:52:00 +0000

These days, a good many cell phones come with a camera built right into the phone itself. Thus, these phones are called camera phones. These built in cameras are hardly noticeable and are unobtrusive to the cell phone user. Camera cell phones are hugely popular and their sales have even surpassed those of regular digital cameras.

Just as with your standard digital camera, resolution on camera phones varies. However, you can achieve virtually the same resolution on a VGA camera phone that you can achieve with a less expensive digital camera.

With current technology, camera phones are continuously being improved and upgraded. With some of the newer phones, picture quality is almost as good as some of the mid level digital cameras.

Competition among camera cell phone makers is fierce, and this is a good thing for consumers. Cell phone manufacturers continuously output better and cheaper camera phones, which gives you a wider range to choose from if you are considering a camera cell phone.

When shopping for your new camera phone, be sure to shop around and compare models, as features vary from phone to phone. Some features that you can choose from are flash, digital zoom and color adjustment. Some phones will also allow you to take self portraits.

Along with the camera feature on these cell phones, you may also be able to use the “photo caller id” feature. When someone calls you, the picture that you have stored in your phone for that person appears on the screen when the phone rings.

Other phones include the option to capture short video clips. In addition to taking photos, camera phones with video capability allow you to record short videos from your phone. This type of camera phone is rapidly increasing in popularity.

So, you have gone out and purchased a camera phone. The camera feature is great but you may be wondering what you will use it for. Besides using your phone to take the normal pictures you might take on a daily basis, there are numerous uses for your camera phone.

For example, if you are having a difficult time deciding on a clothing purchase, you might take a picture and send it to a friend for her opinion. Or suppose you are in a minor auto accident. Simply whip out your handy camera phone to take pictures of the damage and to keep track of the facts. If you are the forgetful sort, you might even decide to take a picture of the row and section where parked your car at a shopping center or in a garage.

Once you decide to buy a camera cell phone, you will invent hundreds of uses that may have never previously crossed your mind. And it only takes a second to snap a quick photo with your camera cell phone.

Cell Phone Text Messaging

noreply@blogger.com (Hopefully Useful) — Mon, 09 Jun 2008 05:51:00 +0000

Cell phone text messaging is exploding worldwide. If you have been struggling to keep your cell phone bill under control, rather than change your plan again, you may consider using the text messaging feature available on almost all mobile phones. You will join the ranks of billions of cell phone text messaging users around the world and maybe even have a little fun in the process.

Usage of the text messaging feature has seen explosive growth. Statistics show that by June of 2004, an average of 100 text messages per person had been sent globally. Text messaging is a quick, convenient, and discrete way to keep in contact with your friends and loved ones that will keep you from burning extra minutes in your cell phone plan each month.

Text messaging is also known as SMS, or short message service, in the technical world. Cell phone users simply refer to them as text messages, or texts. And the popularity of the service has increased three fold over the past year in the United States alone. SMS permits the sending and receipt of text messages between cell phones and other handheld devices, such as PDAs.

Sending a text message to someone's phone is pretty simple. You simply choose the messaging feature on your cell phone, input the recipient’s phone number, and then type your message. Once you are finished typing your message, then you simply choose the send option and your message is sent. Many plans even allow you to send messages from your phone directly to an email address.

In case you are wondering, text messaging is usually a pretty affordable feature. Mobile phone companies may charge $0.10 or less per text message to send and receive text messages. This does not count towards your minutes usage and there is no additional charge.

To save even more when you use this feature, you may choose to add on a text messaging package to your current cell phone plan. Most text plans are relatively inexpensive and can be added for as little as $2.99, depending on how many messages you plan to send each month. Check with your cell phone carrier for messaging plans offered for your cell phone.

Cell phone companies count all messages that you send or receive, whether you read them or not. Messages can be up to 160 characters in length. If you receive a longer message, each 160 characters counts as a separate text message.

You can also use the text messaging feature on your cell phone to receive news alerts, ringtones, and more. However, this is normally classified as premium content and requires a subscription, which is an additional charge.

You may have even seen where many companies and television programs are using text messaging for entertainment purposes, such as voting and entering competitions. It is also used by many to play interactive games. You should keep in mind that you are charged extra for using text messaging in this manner, though.

So go ahead, start cell phone text messaging instead of idly wasting your cell phone minutes on things that can be said just as easily, and more cheaply, using text messaging.

Considering a Prepaid Cell Phone Plan

noreply@blogger.com (Hopefully Useful) — Mon, 09 Jun 2008 05:50:00 +0000

With a prepaid phone plan, you are automatically approved. There is no credit check required – you simply choose your phone and your plan and you are done. In the past, you were limited in choice of phone styles and features, but this is fast becoming a thing of the past. So if you have less than perfect credit, a prepaid cell phone plan may be right for you.

With a prepaid phone plan, you do not have to worry about a bill each month, as you would with a typical cell phone plan. This is because you pay for your minute usage in advance. When you use all your minutes, you can simply buy additional minutes.

Prepaid cell phone plans also include features that you would find with typical contract cell phone plans. They have really come a long way. You can choose voicemail, caller ID, and even text messaging. You even have access to the latest cell phone models, such as camera phones and music capable phones.

Prepaid cell phone plans are also a great option for teenagers who are just learning to handle responsibility. You have peace of mind as a parent knowing that you can stay in touch with your child at all times. You are also freed from worry knowing that your child cannot create any surprise bills for you at the end of the month.

You may also consider a prepaid cell phone plan if you rarely use your cell phone or allocate its use for emergency purposes only.

A prepaid phone plan is great for those with less than the best credit or for those who have little money to spend. It is a great tool for learning financial management skills and responsibility, if you struggle in these areas.

One of the defining factors for many of those who are considering a prepaid cell phone plan is freedom. You are free from contracts. You are free from a monthly bill. You are free to change and switch companies and cell phone plans as often as you wish with a prepaid cell phone plan.

Shopping for a prepaid phone plan is no different than shopping for a typical cell phone plan with a contract. Shop around, assess your needs and choices, and then choose the best prepaid plan for your lifestyle.

How To Choose a Cell Phone Plan

noreply@blogger.com (Hopefully Useful) — Mon, 09 Jun 2008 05:49:00 +0000

For instance, are most of the calls you make during evening hours or on the weekends? If so, you may benefit from a plan that includes free nights and weekends. Also, you may decide on a plan that includes less daytime minutes since you probably do not need as many.

On the other hand, do you make most of your calls during daylight, or peak hours? In this case, you will probably actually benefit with a plan that includes more minutes.

In either scenario, most cell phone providers will allow you to switch or change your plan with a simple phone call, even if you have previously agreed to a contract.

Remember to be polite when you speak to someone about switching your cell phone plan. Rudeness only makes the sales representatives less inclined to help you. They will simply remind you that you signed a contract.

Another consideration when choosing your cell phone plan is if your plan offers free mobile-to-mobile minutes. This means that you can call other cell phone users on the same network at no extra cost. When choosing your cell phone plan, you may want to keep this consideration in mind, especially if a lot of your friends and family use a particular cell phone company.

In addition to mobile-to-mobile minutes, some cell phone companies now allow you to make calls to any number on any network without using any of your allotted minutes for the month. You are able to choose anywhere from five to ten numbers to include in this plan. And when you call these numbers or receive calls from these numbers, you are not charged.

You must also consider where you will be using your cell phone when you choose your cell phone plan. It makes no sense to choose a plan or cell phone provider that does not provide adequate network coverage for your needs. Incurring roaming charges can easily increase the amount of your monthly cell phone bill to an uncontrollable level.

If you rarely use your cell phone, or use it for emergencies only, then a prepaid plan may be a good option for you. However, prepaid cell phone plan rates are typically higher than standard cell phone plan rates. Ultimately, how and where you use your cell phone will determine how you choose a cell phone plan. Just be sure to review the facts and choose wisely.

Internet Phone Service: The Low Cost Alternative for Keeping in Touch

noreply@blogger.com (Hopefully Useful) — Fri, 06 Jun 2008 23:42:00 +0000

Are you always looking for ways to save money without cutting back on the things that make you happy? Do you like to talk on the phone until your mouth is as dry as the desert sand? If you answered yes to these questions, then internet phone service is an ideal fit for you. It works over a high-speed internet connection and allows you to keep in touch with family and friends all over the world for pennies.

In order to enjoy the money saving benefits of internet phone service, you must have a high-speed internet connection, either broadband or DSL. Most Internet Phone Service Providers will then send you a Broadband Phone Adapter, or BPA (a device that resembles a modem) that will plug directly into a modem/router. Then, all you have to do is plug your existing phone into the adapter and you can start making calls. The set-up is really easy and usually takes less than five minutes for installation.

The misconception about internet phone service is that you need a computer to use the service. While it is true that most consumers who use internet phone service do have a computer, one is not required to make calls.

So, how much money are you really going to save with internet phone service versus traditional phone service? Most traditional phone companies usually charge between $20 and $30 a month for basic service. This doesn’t include any features like voicemail, call forwarding, call waiting, 3-way calling, etc. Nor does it include any long distance charges. Add these features up and a normal phone bill would typically cost $50 a month. And, if you ever need to disconnect your phone line or perhaps change your phone number because you are receiving unwanted telemarketing calls, you can expect even more fees.

With Internet Phone service, most providers charge between $20 and $25 a month. Not much difference than the traditional phone companies, right? Well, for this price you not only get all the features included, but unlimited calling in the United States and Canada as well. Not bad if you have friends and family living outside of your area code. Most consumers who use internet phone service can save as much as $500 a year and that is just the icing on the cake.

The cost savings of internet phone service is great. But even better is the ability to keep in touch with family and friends without the worries of high phone bills.

Bluetooth Definition

noreply@blogger.com (Hopefully Useful) — Fri, 06 Jun 2008 23:40:00 +0000

Bluetooth is a specification for the use of low power radio communications to wireless phones, computers, and other network wireless devices over short distances. The name Bluetooth is actually borrowed from Harald Bluetooth, a Denmark king more than 1,000 years ago.

The technology of Bluetooth was primarily designed to support simple wireless networking of devices and peripherals, which includes cell phones, PDAs, and wireless headsets. The wireless signals that are transmitted by Bluetooth cover short distances of up to 30 feet, generally communicating less than 1 MPps (Mega Byte per second).

The networks of Bluetooth feature dynamic topology called PAN or a piconet. The piconets contain a minumum of two and a maximum of eight peer devices. The devices will communicate using protocols that are part of the specification.

Even though the Bluetooth standard will utilize the same 2.4 GHz range as 802.11b and 802.11g, the technology isn't suitable for a Wi-Fi replacement. When compared to Wi-Fi, Bluetooth is much slower, limited in range, and actually supports less devices.

For short range devices, Bluetooth is rapidly becoming the best. The technology is more popular with cell phones, as Bluetooth headsets are the way to go these days. To use Bluetooth, your cell phone will need to have it enabled, or an infared device somewhere on the phone.

Upcoming devices are utilizing Bluetooth as well, such as PS3 and the Nintendo Revolution. The wireless controllers will be Bluetooth enabled, which will give players the cutting edge.

If you own a cell phone or other wireless device, you should look into Bluetooth. The technology is nothing short of spectacular, making it something that will be around for years and years to come. As technology gets bigger and bigger, you can expect Bluetooth to advance as well.

Bluetooth Basics

noreply@blogger.com (Hopefully Useful) — Fri, 06 Jun 2008 23:40:00 +0000

The technology of Bluetooth wireless is a short range communications method intended to replace the cables that connect portable or fixed devices while maintaining the highest levels of security.

The key features offered by Bluetooth include low power and low cost. The specification in Bluetooth defines a uniform structure for a wide range of devices to communicate and connect with one another.

The technology behind Bluetooth has achieved global satisfaction such as enabled devices, almost everywhere in the world. Bluetooth devices will connect and communicate without wires through short range and networks known as piconets.

Each device will simultaneously communicate with up to seven other devices within a single piconet, meaning that each device can also belong to several piconets simultaneously. The piconets are dynamically established as Bluetooth enabled devices enter and leave the proximity of radio.

A fundamental to Bluetooth strength is the ability to handle both data and voice transmissions simultaneously. This will enable users to enjoy varieties of innovative solutions such as hands free talking, printing and fax capabilities, and other applications.

Specifications - Unlike other standards of wireless, the Bluetooth specification gives product developers both a link layer and application layer definitions, which will help support data and voice applications.

Spectrum - The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal.

Interference - The adaptive frequency hopping of Bluetooth technology was designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum. Adaptive frequency hopping (AFH) works well within the spectrum to take full advantage of the frequency available.

AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they are using other technologies along with Bluetooth.

A Dummies Guide to Broadband Phone Service

noreply@blogger.com (Hopefully Useful) — Fri, 06 Jun 2008 23:37:00 +0000

Did you know that the Internet can totally replace your existing phone line? With broadband phone service, you can make and receive telephone calls using a regular phone without the assistance of your local phone company. Instead, the phone plugs directly into a broadband internet connection, either cable or DSL. It’s easy, fast and affordable.

You need two things to turn your internet connection into a personal phone line: a subscription to broadband phone service and any traditional phone (analog or digital). Most service providers charge between $20 and $30 a month, not including additional taxes and fees.

Once connected and installed, broadband phone service works just like a regular phone: pick up the phone and you will hear a dial tone – dial a phone number – wait for the person to answer – and start talking. In most cases the person on the other line won’t even know that you are using broadband phone service; the quality is that good.

Some of the benefits of using broadband phone service include: unlimited calling to the U.S and Canada, free features like call waiting, caller id, call forwarding, follow me – find me, three-way calling, online bill pay, voicemail, voicemail to email notification, and the ability to choose your area code. This means that you can live in New York and have a California phone number. Most broadband phone service providers also offer a trial period or a 30-day money back guarantee.

Most, if not all, broadband phone service providers allow you to keep your current phone number; a process called local number portability (LNP). This process usually takes between six to eight weeks depending on the provider. If it takes any longer, most of the time it is the phone company that is releasing your phone number that is holding up the process.

Some additional features of broadband phone service are virtual numbers (a number in a different area code, that when dialed rings directly to your main number). Virtual numbers eliminate long-distance phone charges for anyone calling within that numbers' area code; and usually cost an additional $5 a month. Most broadband phone service providers also offer toll-free numbers and 411 directory assistance for a low monthly fee.

Due to the recent FCC regulations, all broadband phone service providers must have E911. What this means for you is that you if you subscribe to broadband phone service and dial 911, the call will be routed to the local public safety dispatcher with your address information pre-populating on their screen. When searching for a broadband phone service provider, ensure that they offer E911.

Bluetooth And Apple

noreply@blogger.com (Hopefully Useful) — Fri, 06 Jun 2008 23:35:00 +0000

The new Apple powerbook G4 are among the first computers to offer Bluetooth technology 2.0+EDR. The 2.0+EDR technology, which still backwards compatible with 1.0, is up to three times faster than previous versions, offering maximum data rate transfers of up to 3 MBps. Being the first company to certify a system with 2.0+EDR, Apple continues to make great use of the Bluetooth technology.

Full support - In addition to the powerbook G4 portables, there are other Bluetooth enabled computers available from Apple, including the iBook, iMac G5, eMac, and the Power Mac G5.

Making life easier - When you turn the Bluetooth feature on, your Mac can easily perform a file transfer or even a synchronization. From the Bluetooth selection menu, you can choose to either send a file or browse devices, quickly and easily. Or, you can click the sync button in iSync to update your cell phone or Palm OS handheld.

The Mac and GSM/GPRS mobile phone with Bluetooth work to make each other more useful. By using iSync, you can keep your phone updated without having to type any info, as you can keep the information in the more manageable address book on your Mac instead.

You can also use your Bluetooth enabled Mac to print documents and digital images to select a printer that also supports the technology of Bluetooth. Or, you can also use a headset to talk to your friends during an iChat session.

Your Mac also has the ability to use Bluetooth technology to communicate with your Palm OS handheld. This way, you can perform a HotSync operation without using any cables. You can also send your business card or calendar events directly to someone else's handheld usingthe technology of Bluetooth.

The implementation of Bluetooth by Apple is the latest in a series of moves that have caused great shift in the computer industry. Apple established USB as the standard interface with the launching of the first Mac back in 1998.

Since then, Apple established the 802.11 wireless standard of networking with the launch of the iBook and AirPort in 1999. During 2003, Apple launched AirPort Extreme, which was based on the new 802.11g high speed technology of wireless.

Now, Bluetooth helps to further strengthen the dominant position of the Mac in wireless communications, helping to preserve Apple's reputation for being the first to market with innovative technology that integrates right into the operating system.

VoIP Explained Easily

noreply@blogger.com (Hopefully Useful) — Thu, 05 Jun 2008 21:12:00 +0000

With the increased adoption of high-speed Internet across the U.S. and abroad, it has become much easier to send and receive large amounts of data without affecting bandwidth. What this means for consumers is that they can now download huge files quickly, browse multiple web pages simultaneously, and even make telephone calls over the Internet; an emerging technology known as VoIP.

VoIP stands for "Voice over Internet Protocol " and it is quite simply a way of using the Internet to make and receive telephone calls. The primary reason VoIP is becoming so popular is cost and convenience; as VoIP is significantly less expensive than typical local and long distance telephone service offered by the phone companies. Additionally, one high-speed Internet connection can serve for multiple VoIP telephone lines.

How does VoIP Work?

A normal telephone line would sit there and do nothing if it weren’t connected to a network called the PSTN (Public Switched Telephone Network). This is how the traditional phone companies route telephone calls from one person to another. In VOIP service, the PSTN is replaced by the Internet as the network for routing phone calls, and is proven to be faster, more efficient and cost effective.

Using VoIP, a person’s voice is transmitted into digital data that is then sliced into small fragments called packets that are sent across the Internet at lightning speed. These packets are then reconstructed and heard on the receiving phone. Sounds like allot going on during a phone conversation, but most people who use VoIP phones don’t even know they are making telephone calls over the Internet; the call quality is that good.

In order for VoIP phone calls to have the same quality that consumers are accustomed to when using traditional phone service, a certain bandwidth (the amount of data that can be sent) is required. Broadband Internet access, either cable or DSL, provides the necessary bandwidth for VoIP phone service to be found acceptable by consumers.

The Features of VoIP

In addition to making high-speed Internet access more cost-effective, VOIP service provides subscribers with significantly cheaper local and long distance telephone service. Most VoIP providers charge between $20 - $25 per month and this includes unlimited calling to the U.S. and Canada.

Additionally, all the features that traditional phone companies usually charge for like voicemail, caller id, call waiting; three-way calling, simultaneous ring and the ability to choose your own area code are included in the price.

Another driver for using VoIP is that it is portable. In other words, consumers can take their phone number anywhere they move to; even if it is just on vacation.

Cost savings, free features, portability – VoIP is the emerging technology at the root of all these trends, and consumers should expect to see a lot more news about VoIP in the coming months and years.

Bluetooth And Infared

noreply@blogger.com (Hopefully Useful) — Thu, 05 Jun 2008 20:31:00 +0000

With new electrical devices being produced every day, the problem of connecting things is becoming more and more complex in nature. The system that comprises computers and other electronics makes use of varieties of wires, cables, etc.

These parts will communicate through light beams, lasers, radio signals, and infrared. The problem however, is the devices and technology is often the connection between each component. Therefore, most electronic systems aren't used to their full extent due to the problems and imperfections.

To help simplify things, a solution was created -the solution of Bluetooth. Bluetooth is wireless and automatic, offering users a variety of features that have simplified the art of connection. Bluetooth has revolutionized the standard methods of connecting things to enabling almost anything to be connected to a single system.

Aside from Bluetooth, there are other ways of connecting wireless devices. One example of such is the IR or infrared. Infrared allows low frequency light waves to transmit signals to another component. This technology is easy to create and the cost of putting the IR device into a system is rather low.

Infrared technology is a one to one process. Due to the limitation, you may only send signals from one device to another, similar to a television set and remote control. You can only transmit signals between the two although not with a seperate system.

Aside from the fact that these two natures of infrared are obstacles to acquiring results, these same qualities have worked in advantage to the connection. Infrared devices need to be lined up directly, meaning too little interference can occur between the transmitters and receivers.

The technology behind Bluetooth works by transmitting signals through low frequency radio signals. The path of communication is working on 2.45 GHz, which is the same frequency band used in ISM devices.

Bluetooth Technical Operations

noreply@blogger.com (Hopefully Useful) — Thu, 05 Jun 2008 20:24:00 +0000

Bluetooth is a high speed, low powered wireless link technology that's designed to connect phones or other portable equipment together with little to no work required by the user. Unlike infrared, Bluetooth doesn't require line of site positioning to work.

Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed.

When one Bluetooth device comes in contact with another, they will automatically exchange addresses and details of capability. Then, they can establish a 1 MB link with security that they will use as required. The protocols involved with handle both data and voice, with a very flexible topography.

The technology achieves its goal by embedding tiny, non expensive short range tranceivers into the devices available today. The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels.

Each devices offers a unique 48 bit address from the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power. The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.

What's important, is the fact that Bluetooth devices won't drain battery life. The specification targets power consumption of the device, limiting the drain on the battery. The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.

Bluetooth will also guarantee security at the bit level. The authentification is controlled by the user via a 128 bit key. The radio signals can be coded with anything up to 128 bit. With the frequency hopping, Bluetooth is already very hard to listen into.

The baseband protocol is a combination of both circuit and packet switches. Slots can be reserved for synchronous packets as well. Each packet will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.

Bluetooth can also support data channels of up to three simultaneous voice channels. Therefore, it's possible to transfer the data while you talk at the same time. Each individual voice channel will support 64 KB.

From a technical standpoint, Bluetooth is very different indeed. It's the best wireless method in the world, surpassing even infrared. For communication on the go, Bluetooth is indeed very hard to compete with.
