No one had ever imagined that the mini mobile device would become a necessity for everyone. There was a time when mobile phones were rare and very much expensive. Now, things are totally different and mobile phones have become the easiest and cheapest source of communications. The unprecedented growth in the mobile industry have totally metamorphosed the mobile world. Packed with advanced features, latest mobile technology is at par with the information technology. The technological growth in the mobile industry is still going on. And, as a consequence, every next day new and latest mobile phones are being launched. From entertainment to business features – latest mobile phones are more than just a communication device.

With the introduction of 3G technology, mobile industry has again come up with something that no one had ever expected before. This technology not only offers fast data connectivity, users can also access broadband speed internet. After the launch of 3G phones, mobile companies are now introducing HSDPA enabled phone that are more advanced than the 3G. HSDPA enabled phones come under 3.5G category that offer 10 times fast data transfer and internet connectivity than the 3G phones. Nokia has introduced the first HSDPA enabled phone in its N series portfolio, the Nokia N95.

Verizon Wireless PDA /Blackberry ???

I need to upgrade my PDA, I’m not sure which one of these is good.
Any comments,reviews,experiences??>??? thanks

1.Verizon Wireless XV6900
2.Samsung Omnia™
3.HTC Touch Pro™
4.BlackBerry® Storm™ 9530 smartphone
Jamal, thanks for the info isn’t the Palm Pre through Sprint?

1. XV6900 is a solid phone but not so much for Verizon, especially since its GPS functions are disabled and unlike other carriers it doesn’t have wifi, on top of that it’s soon to be discontinued as evidenced by the treo pro.

2. The Omnia is perhaps the most solid and has the best processor of any windows mobile phone for verizon. it has built in wifi, radio, memory, etc. this is your best bet. If windows mobile didn’t suck so much it would probably knock the iphone out.

3. The touch pro has a wonderful keyboard, interface, you name it, it is an HTC after all. This phone is also very solid, although if you want battery life this phone will die pretty quickly.

4. The blackberry storm is basically a good idea but it hasn’t been fulfilled to the tee. The only problem I can find with this is the buggy blackberry software and the lag that comes along with any full touch device.

If I were you I’d just hold out for the Palm Pre coming for spring, it’s touch screen is basically the iphones and from what Ive heard its a definite iphone killer. I’d also check out some of the Alltel phones since they are basically verizon now and they do have the Treo Pro. Also check out http://www.cnet.com for reviews on the phones your looking at. Hope I helped.

What do u mean by mobile communications?Any good examples?

I need it 4 a project .When I asked Ma’am she told Bluetooth Radio etc.Any more examples

Mobile communications refers to any mode of information transfer that can be done outside a base location. That can mean almost anything, from an old fashioned portable radio to the latest phones and computers. However, from a modern standpoint, I believe you are speaking strictly about cellphones, handheld computers, satellite connections. etc., that allow any user to have two-way communication with others outside of a set "home" location. Bluetooth is just term used to describe a specific technology within mobile communications. Basically, you’re talking about the hardware/software combo that allows people to communicate from any location, both as senders and receivers.

technically, what is the difference between CDMA and GSM wireless services?

hi i am a electronics and communication engg student and looking for a fundamental , technical answer please help me out plzzzzzzz ……..people tell me the answer for this

CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code) to allow multiple users to be multiplexed over the same physical channel. By contrast, time division multiple access (TDMA) divides access by time, while frequency-division multiple access (FDMA) divides it by frequency. CDMA is a form of "spread-spectrum" signaling, since the modulated coded signal has a much higher data bandwidth than the data being communicated. An analogy to the problem of multiple access is a room (channel) in which people wish to communicate with each other. To avoid confusion, people could take turns speaking (time division), speak at different pitches (frequency division), or speak in different languages (code division). CDMA is analogous to the last example where people speaking the same language can understand each other, but not other people. Similarly, in radio CDMA, each group of users is given a shared code. Many codes occupy the same channel, but only users associated with a particular code can understand each other.

———————-

GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. There are five different cell sizes in a GSM network—macro, micro, pico, femto and umbrella cells. The coverage area of each cell varies according to the implementation environment. Macro cells can be regarded as cells where the base station antenna is installed on a mast or a building above average roof top level. Micro cells are cells whose antenna height is under average roof top level; they are typically used in urban areas. Picocells are small cells whose coverage diameter is a few dozen metres; they are mainly used indoors. Femtocells are cells designed for use in residential or small business environments and connect to the service provider’s network via a broadband internet connection. Umbrella cells are used to cover shadowed regions of smaller cells and fill in gaps in coverage between those cells. Cell horizontal radius varies depending on antenna height, antenna gain and propagation conditions from a couple of hundred meters to several tens of kilometres. The longest distance the GSM specification supports in practical use is 35 kilometres (22 mi). There are also several implementations of the concept of an extended cell[12], where the cell radius could be double or even more, depending on the antenna system, the type of terrain and the timing advance.

Indoor coverage is also supported by GSM and may be achieved by using an indoor picocell base station, or an indoor repeater with distributed indoor antennas fed through power splitters, to deliver the radio signals from an antenna outdoors to the separate indoor distributed antenna system. These are typically deployed when a lot of call capacity is needed indoors; for example, in shopping centers or airports. However, this is not a prerequisite, since indoor coverage is also provided by in-building penetration of the radio signals from any nearby cell.

The modulation used in GSM is Gaussian minimum-shift keying (GMSK), a kind of continuous-phase frequency shift keying. In GMSK, the signal to be modulated onto the carrier is first smoothed with a Gaussian low-pass filter prior to being fed to a frequency modulator, which greatly reduces the interference to neighboring channels (adjacent channel interference).

LG KF750 (Secret)

Boasting style that lasts, the LG Secret has been specifically developed to satisfy the refined tastes of trendsetters who desire a sophisticatedly designed, yet durable handset. Following the success of its predecessors, the LG Chocolate and the LG Shine, this third model from the LG Black Label Series is as feature rich as it is stylish. At just 11.8mm thick, the LG Secret is the slimmest 5 megapixel camera phone on the market.

Skott Ahn, President and CEO of LG Electronics Mobile Communications, says, “Trends in the mobile phone market prove that today’s discerning consumer is looking for the ultimate mobile experience — style and substance. The great success of the previous LG Black Label Series models proved this and the LG Secret continues this style led technology legacy.”

Timeless style
The LG Secret will always look as new as the day of purchase thanks to the materials used to make it. Its casing of carbon fibre, one of the strongest composite materials used for aircraft and high-performance cars, adds to the handset’s durability. Its tempered glass LCD adds sheen and strength, as well as shielding the phone’s screen, and its neon touch navigation buttons sensitively respond to commands with a luminous blue light.

Timeless memories
As well as being the slimmest 5 megapixel camera phone, the LG Secret boasts the ability to take video at 120 frames per second and DivX® certified recording. Timeless moments can be edited with powerful photo and video editing features, including facial editing and SmartLight™, a feature that automatically adjusts the picture’s light settings. Users can also create their own music videos using the phone’s Movie Maker software.

Timeless entertainment
The LG Secret’s outstanding entertainment features take advantage of the phone’s touch-screen – users can access five multimedia functions which include music, photos, games, documents, and the FM radio. In addition, users can simultaneously flick through photos on the screen while listening to music. Microsoft documents can be opened easily and the handset is loaded with a Google package that enables the user to surf the Internet, log into Gmail, use Google Maps and watch YouTube videos.

Timeless convenience
Using Bluetooth, the LG Secret automatically synchronises with PCs without the need to use USB cables. Images can be viewed both horizontally and vertically using the phone’s auto rotating display, and the screen’s lighting adjusts to ensure that it is always clear. In addition, the phone also comes with Voice Clarity technology that guarantees perfect sound quality in every environment.

After its European launch, the LG Secret will be launched in Asia and South America, followed by the rest of the world. Please visit the LG Secret Microsite at http://secret.lgmobile.com

The Future Of Wireless Uk Broadband

Wireless broadband in the UK has never seemed to take off as well as wired broadband. Most households in the UK have the ability to get broadband internet, but wireless access is limited.

There are many reasons why wireless internet is better than wired internet, but in the UK it seems that no provider can get it to work for the users. It may just be, though, the answer to those living in remote areas where broadband service is less than desirable.

The wireless providers are finding a niche market in remote areas, the younger generation and business minded people who are seeing the perks of a wireless connection.

The difference between wireless and wired internet is basically that wireless internet uses no wires, where wired internet does. A wireless service is sent through radio signals instead of through lines and cables.

A person with a wireless connection can hook up to the internet without ever hooking anything into their computer. With a little set up the computer is ready to be used with a wireless internet service.

Then a person can use their computer wherever they like, as long as it is within an area where wireless broadband is offered. Wireless internet provides so much freedom to both providers and users.

For the provider wireless UK broadband is a far better solution than wired. Wireless internet connections are much easier to set up and maintain than wired services. It is also far easier to get wired services to remote areas than wired services, which is why wireless service is heavily promoted to people in those areas.

For the user, wireless internet offer flexibility. Nothing wired into a computer, no need to add new lines and far fewer maintenance issues.

With a wireless connection a person is no longer confined to their home, hooked into the broadband connection, they can use their wireless connection around their home or in many of the public places that offer wireless broadband access, like pubs or restaurants.

Wired internet is most popular for laptop computers and mobile phones. Many people do not see the idea stretching to their home computer and feel that it is complex and too involved for them to deal with. With three-quarters of the population of the UK using broadband services, only a third are actually using wireless technology.

The internet choices in the UK change rapidly. Wireless UK broadband is still fairly new, but many companies are jumping onboard to provide it to their customers. Currently wireless

UK broadband is available to limited areas. As the providers work through the kinks and get more users interested, it is likely that wireless broadband will overtake wired broadband as the internet service of choice.

Why Is Wireless Technology Is Taking Over How We Live ?

Wireless Internet technology, also known as WiFi, is really taking over the way people access the Internet and it has become widely popular in a very short time. The reason for this is it allows individuals to access the Internet via a network hot spot without the use of cables or wires. The signal is simply transferred through radio signals, which makes connecting to the Internet via your computer in different locations very easy.

Since wireless technology makes connecting to the Internet as simple as possible, many businesses, universities, hotels, cafes, schools, airports and homes are realizing the importance of offering easy Internet connections to both students and professionals. Generally, hotspots are offered to patrons at a reasonable hourly rate or either free, depending on where the hot spot is and who the target market is.

The one disadvantage these businesses have that install wireless networks is that any user in the area of the network can log on. For those offering free service this is not big deal, but for those charging for Internet it is. There are, however, security precautions that can eliminate unauthorized users that include a virtual private network and Internet Protocol Security.

The hot spots are really catching on worldwide, so if you are traveling or even just in your city, you will notice many areas that say hot spot or Internet zone. Cafes and bookstores as well as hotels and airports are some of the more popular areas that you will see on a regular basis with hot spots. However, more and more locations are noticing the need for this service and offering it.

If wireless Internet is something you really enjoy in the real world, then you can also have it in your own private home or business. It makes working or surfing the web significantly easier for all the Internet users because you can work wherever you need or want without the hassle of a lot of wires and cables. So, if you want wireless Internet go ahead and have it installed or install it yourself because it is really effortless and takes little time.

There is some equipment you will need to get started, of which you can buy yourself or pay a technician for all of the equipment and the service of installing the wireless Internet. Basically, you need to have a high speed Internet service, a router, and then each computer that will access the network needs a wireless Internet card if you did not buy it WiFi ready.

If you want to install wireless yourself you should simply buy the recommended materials and then follow the directions. There is a lot of help online that will guide you through the process. However, if you don’t feel like dealing with the headache then simply hire a technician to handle the whole process for you.

Finally, when you have wireless Internet installed in your home or office, remember that you should take some precautions to prevent your neighbors or other unauthorized users from stealing your Internet. A virtual private network or Internet Protocol Security will secure your network and allow only authorized users to connect.
