For the last several years, everyone has been talking about 3G technology in mobile phones. Of course, it was simply a matter of time before something better and faster took its place. That’s where the Sprint HTC EVO 4G, America’s first 4G wireless phone, comes in. Scheduled for release on June 4, 2010, the HTC EVO 4G features a spectacular 4.3 inch touch screen, dual cameras including an 8 megapixel main camera, and speeds up to ten times faster than 3G. In fact, the HTC EVO 4G is as high-speed and powerful as a regular DSL and cable wired connection. Additionally, users will have access to more than 30,000 apps from the Android marketplace.



There are actually several amazing features that will be integrated with the HTC EVO 4G. As mentioned previously, the cellular phone includes two cameras. The main camera at 8 megapixels is capable of shooting HD video. The secondary camera at 1/3 megapixels is ideal for video chatting, vlogging, and self portraits. The 4.3-inch touch screen is the largest screen offered thus far in smart phones, and is capable of viewing HD content.



However, the most extraordinary feature is the 4G network, enabling download and viewing speeds previously unheard of in cellular phones. While the 4G network is still expanding, and is therefore not offered in all areas, the mobile phone can still be used on the 3G network while waiting for expansion. The advantage is that there’ll be no need to upgrade when the 4G network becomes available in all areas.



In addition to the higher end features, the HTC EVO 4G also provides smaller features which will no doubt make the phone a lot easier and more pleasurable to use. For instance, the back of the cellular phone has a kick stand, which could be used to prop the phone up when reading large amounts of information, or watching videos. The HTC EVO 4G also has a built in FM tuner, a feature lacking on most other smart phones. Also, the integrated 4G hotspot capability makes the cellular phone a mobile hotspot for up to 8 other wireless devices.



Not only will the HTC Evo 4G come fully packed with features, HTC is planning to launch OEM accessories for the Sprint Evo 4G, including a desktop charger and car mount holder. Since the Evo 4G is extremely popular, there’ll be many HTC Evo accessories available in the near future ranging from extended batteries to waterproof cases. This will greatly enhance the visualization and functionality of the Evo 4g.



Overall, the HTC EVO 4G is a technophile’s dream, and will undoubtedly transform the way that everyone uses their cell phones.

Whether you know, that the majority of phones GSM support such useful service as a data transfer and a fax? By means of a mobile phone it is possible to “live” in the Internet, to send e-mail, to remit the data from any corner of the Earth. No, no, here I don?t talk about WAP-technology, but “the usual” cellular telephone. is it not necessary for you? Access to the Internet, e-mail is carried out from office or from the house, and there is no necessity to connect a mobile phone to the computer? You are mistaken!



And what about editing a notebook in phone? To do it is much more convenient on the usual personal computer. And to use it as an organizer? And to send short messages from the habitual computer keyboard? It would be for this purpose quite good to connect a mobile phone to the computer. All it allows making the majority of models of modern GSM-phones as manufacturers provide connection possibility to the computer almost all devices.



Modern models of phones for this purpose are equipped by the built in hardware modem with access through infra-red port or a nest for a cable directly connecting a tube to the computer (the others – alas – require a special interface card).



Infra-red port:



One of possible methods of connection of phone to the computer is communication through infra-red port. All infra-red transfer occurs in a range of lengths of waves from 850 to 880 nanometers. Meeting the specification allow to have range of transfer to 1 meter. The infra-red interface uses the universal asynchronous transceiver (UART) in COM-port. Such port is present practically on all computers. UART has some speeds of data transfer in a range from 2400 bats/c to 115 Kbit/c.



All equipment consists of several functional blocks: the coder/decoder for the coding of an infra-red signal by transfer and decoding at reception and an infra-red radiator for transfer, and also the receiver-detector. The Coder/decoder has the interface with UART.



Instead of sending a signal on a cable as it is carried out between the computer and the external modem, it transforms the data to the public. In general, all is simple enough. The basic problem is in that the corresponding interface in a ready kind is absent at 99 % of desktop computers. It is in the majority of laptops and pocket computers.



However the situation is not hopeless even for holders of desktop computers. It is possible to acquire infra-red adapter MA-600 which is connected to the computer through the CATFISH-PORT and serves for communication of the personal computer with mobile phones, pocket and portable computers, digital cameras. Put phone opposite ??-600 (previously do not forget to install corresponding programs) both start to work. Also do not forget that phone should be from the infra-red adapter on distance from 1 to 100 sm and at an angle no more than 30 degrees.



The sizes ??-600 are so small (80?42?30 mm) that it will not take a lot of place on a desktop.



In shops it is possible to meet and other similar items, very often they stand considerable money. The corresponding module can be made the hands as the set of firms is manufactured by special components of Ir-interfaces which represent a combination from light – and the photo diode with additional elements. The method of manufacturing of the similar interface can be found in the Internet easily.



Modern high technologies have taken up the world and our minds. Can you just imagine our life without all those computers, phones and automated machines?

Polyphonic tunes will supply your device with unique “voice” which you will not confuse with calls of another’s phones. However, habitual ringtones of phones without polyphony as a rule it is more shrill also it easier to hear – so function of polyphony more likely aesthetic, than practical.



If you do not like to disturb associates in your phone should be vibration signal. Before purchase without fail test it is for different models “vibrate” has different power.



The color display: If it is more colorful (both under the permission and on the size) – the more conveniently it is to use, because also information is easier to display. Another, sometimes not less important characteristic of the display is brightness. It is important, that it was sufficient for screen usage on a bright daylight.



Voice-activated control and vocal set, in particular in a combination to a public address system are irreplaceable in the car and other situations when to use phone keyboard inconveniently.



Many models have a dictophone function, but for records of more minute-two there is no phone internal storage. In that case very useful there can be a possibility of usage of maps of flesh-memory – duration of record will increase in tens and hundreds times. It is possible to write music to a map in format MP3 - phone with font type will turn to a compact player.



The digital camera: For reception of qualitative pictures the cameras built in phone are unsuitable: the permission insufficient (for example for Motorola E365 maximum 640×480), and optics any. For reception of photos, suitable for the press, it is better to buy the digital camera. Advantages of the built in camera – portability and possibility of immediate transfer of a photo on other phone or an e-mail address. It is possible to accompany also records of an address book by photos of targets, and card sharper use possibility of shooting for peeping behind distributed maps – who will pay attention to a usual mobile phone lying on game desktop?



To some phones sell replaceable panels or even sometimes panels go in a package to new phone, for example, to Nokia 6610 it is applied six different panels!). This possibility will please you if you love a variety of different panels that you can switch.



Convenience of the phone menu: Usually buyers pay attention to ergonomics of the screen menu of phone already after phone acquisition. And it is a pity; after all besides that phone possessed certain functions, it is necessary still that they were convenient to use! At phone choice try to walk around various subparagraphs of the menu – this process should not call the irritations necessary to you of function should be readily available.



Modern digital technologies have completely absorbed the world and our minds. Can you just imagine our life without all those computers, phones and automated machines?

The extension of networks of a mobile communication and constant lowering of tariffs and the prices for phones has led to that “mobile phone” can be detected not only in a Mercedes of the succeeding businessman, but also in a pocket of the student, even in a bag of the grandmother-pensioner!



However, these phones, most likely, will be different: for the businessman – the business class model, the student will prefer image phone, and destiny of pensioners is an economy class. However, division into classes is enough conditional: for example, the hit of a business class of last years, Ericsson R520, concerns now budgetary models though on functionality it still can give odds to many modern handsets. The situation in the market varies very fast: there are many new models, old promptly become cheaper and are laid off, and cellular communication operators add new services, to take advantage with which it is possible only on the advanced phones.



To the buyer it is necessary not only to search for the answer to a question: “How to select a mobile phone?” But also to be defined with the operator and the tariff schedule. And to make it is necessary before selection of model of phone: after all each operator uses the standard of a mobile communication.



We will accept, you have decided to take advantage of services where the CDMA-compatible device is required to you, the most widespread GSM-phones will not approach! Now in the cellular communication market following standards are presented: GSM, NMT-450i, D-AMPS, and CDMA. Basically, if you do not have any special reasons to select certain standard ?it is necessary to stop on GSM, as the most universal and extended.



In this standard some providers work at once and you can always replace the operator – for this purpose it will be enough simple to insert other SIM-card into phone. Advertised on the TV and exposed in show-windows of compartments of link phones – phones of standard GSM.



Many know that phones like Motorola, Samsung or Panasonic, but not all in course that phones happen grey and white. If you see on a show-window phone with suspiciously modest price is a sure sign of “grey” delivery. From “white” (phones officially delivered by the manufacturer) they differ that initially has not been intended for wide sale and could be used only in a combination to SIM-cards of the certain operator (from here and the low price is a discount of the operator to the buyer, decided to take advantage of its services). To take advantage of such phones it is necessary to “decode” – to replace wearing so that to remove limitation on the operator and to enter country?s support. As a result phone purchase turns to a lottery: the winner saves some percent from the device cost.

The following thing helps to be defined with a set of services (to which should correspond a set of functions of phone). We will consider some of them:



Message passing:



Now there are three sorts of message types of sending: SMS, EMS and MMS.



The Internet (GPRS)



Presence of GPRS allows receiving and sending electronic letters, to visit Internet servers, to use phone as the modem. Finally usefulness of this service is defined by possibilities of phone: it should possess, at least, well display for high-grade mapping of the information. If you are gathered to quit in the Internet from a notebook or the handheld computer through a mobile phone so it should be solved in advance, what way of connection with phone will be used (for example through a connective cable or IR-port). Further we had the development of technology GPRS ? EDGE and by means of this technology speed of data exchange increases twice.



Data transfer



If it is necessary to transfer a picture or a tune to other phone, to load the data from the computer, to connect a notebook or the pocket computer to the Internet through phone so for you data transfer functions will be necessary. The most technical simple and accessible way of connection with the computer – through a parch cord connected to USB or COM-port.



In the presence of similar connection and the special software there is a possibility of editing of an address book of phone on the computer, synchronization of an address book of phone with the computer data, loading of tunes (for example in Siemens S55 it is possible to load files MIDI), pictures and logos, upgrade of wearing of phone. For connection by a cable there are two disadvantages: absence of universality (to different phones various cables are necessary, it is possible to be connected only to the computer) and, as it is strange, the high price (they should be bought separately).



Connections on built in IR-port (an infrared port, IRDA) and to radio interface Bluetooth are much more universal. IR-ports are more extended, but to using them is not so conveniently as it is necessary to allocate devices on small distance in the field of direct visibility. And speed is also small. Link by radio and faster, and phone not without fail to get from a pocket – it is convenient! And it is possible to buy special Bluetooth-set – then it will be possible to speak by phone which lies, for example, in a glove compartment of your car (and even to type numbers in the presence of a vocal set). A minus, as well as for all good, is one that is insufficient prevalence Bluetooth and the high price.
