I think no need to explain what a smart phone. All have many times heard or read about cell phones that can transmit and process not only voice but also data. Basic standards of transmission and presentation of "mobile data" seems to be designed and agreed upon, and the creation of phones capable of working with them - the problem is quite technical. Moreover: even sold cell phones with built-in capabilities of data processing and Internet access, such as Nokia 7110 or Communicator. It would seem - what else can be said on this subject? However, just to teach mobile phone to send, receive data and are displayed them on the screen is completely insufficient to call it a smartphone Th. And manufacturers, realizing this, do not consciously use the term "smartphone" in advertising. Why? Let us try to understand the deeper issue. The main properties of a smartphone should be: Compact. The size and weight it should correspond to the average mobile phone. Communication. Smatfon should be able to operate as a voice communication (like a regular telephone) and packet data. In addition, the smartphone should their quality process, display and store. Versatility. This refers to what a smartphone should the device be the all-in-one. That is, provide the owner needed to run a set of tools and instruments. Compatibility in the broadest interpretation of the term. Convenience. The most important criterion. It comes as a clear understanding of why you need a smartphone in principle (and an awareness of user convenience Smartphone general), and the quality of the concept of a specific model. We'll see how things stand with each of these items today.
Compactness
Technological level of today is high enough to create mobile phones and computers that can fit in a wristwatch. The main problem - with a decrease in the size of the device reduces its screen and keyboard. The dimensions of a modern mobile phone is physically too small to accommodate a convenient display. Telephone keypad and is not well suited for an entry-nubud serious amounts of data. With this same problem constantly faced by developers handheld computers (HPC). And successfully solve. Lack of screen space is compensated by carefully thought out user interface and keypad can be compressed, to refuse unnecessary for a handheld device keys to pull, but you can completely replace the virtual on-screen handwriting input, or voice interface (it's in the future).
Communication
Since voice communication is more or less clear. With the data difficult. The problem has two aspects: how to get information and what to do next. With the first principle seems to be clear. All modern mobile communication standards are capable of providing data transmission. Most suitable for this GSM and CDMA. However, even these data rates do not exceed 9600 and 14,400 bps, which will agree, is not enough. The problem has two possible ways to resolve. The first - a significant increase in network capacity, for example, using packet dannyh.Bolshie hopes are pinned on which was introduced into the near future in the GSM system GPRS, providing speeds of up to bps. The second way - the optimization of the transmitted information itself. An example would be actively promoted by the current WAP (Wireless Application Protocol) - a protocol for reporting on the Internet for wireless mobile devices. The data were obtained. They need some way to view and save. That is a smartphone should be built into the tools for working with e-mail, SMS (short messaging), Web-pages, etc. And in addition, funds are required to create documents, view attachments, e-mail, to work with corporate databases and much more. Very important qualitative and simple interface exchange with rasprostrannymi desktop, a tablet computer, HPC, and other devices. Here smartphone developers can also benefit from the experience of manufacturers PDAs, faced a little earlier with similar problems and teach them to overcome.
Versatility
Smartphone must fully integrate itself into several different devices: mobile phone, organizer, computer, etc. From each of them should be taken exactly necessary and sufficient.Today, some semblance of a smartphone can be obtained by connecting the handheld computer (PC-organizer) with a cell phone. Modern GSM network can accurately determine the location of a subscriber - add here positioning system on the ground. You can embed a digital camera and organize the transfer of images. Task - from multiple devices to make one, do not overdo it and not cutting off anything extra. Equally important is the openness of the operating system and the ability to create additional applications for its third-party developers. This greatly increases versatility of the tool: it can be applied to the most specific tasks.
Compatibility
Sore spot of computer equipment. The great thing about the device loses its meaning if it is compatible only with itself. Especially if it claims to be the role of personal information center smartphone. It was to achieve maximum compatibility are all sorts of alliances of manufacturers. Such, for example, created specifically for the development of operating systems and principles of organization and communication devices of the future corporation Symbian, which is owned by both Ericsson, Nokia, Motorola, Matsushita and Psion. The same pattern seen in the development of the radio interface for exchanging data over short distances Bluetooth. Some of the successful development are gradually becoming the de facto standard and accepted by manufacturers. So can occur with the Java language and related technology Jini, brings together the different household devices in the network and remotely manage them. There is hope that someday the competition standards will change the competition for their implementation, and specific devices.
Convenience
This is an important quality. It combines all the previous ones, adds simplicity and clarity of it to anyone, the user, even the most inexperienced. Convenience defines the success of the concept in general and specific models in particular. The smartphone has become a convenient solution to some pressing issues for the potential user, otherwise it will remain unclaimed. Example - Nokia Communicator 9000, turned out to be very uncomfortable and did not receive because of this wide distribution. Need to carefully consider why you might ponazhobitsya smart and think about how this or that problem is better solved. If the convenience of new items will be higher than its price, then very soon your smartphone will go down in our lives, as happened with computers, mobile phones, and before television, cars and other wonderful inventions of mankind. Not so important, what will be inside the smartphone: EPOC, Windows CE, Palm OS, Linux or some other operating system. Perhaps smartphones from different manufacturers will have a completely different fillings, there is nothing tragic. User in this case be able to choose that for him is more important - ease, a variety of additional software, multimedia, or something else. Perhaps in smartphones will try to combine the best qualities of each of the currently existing platforms. More importantly, the device must be easy to use. It is convenient in combination with a reasonable price in the state to ensure the success in the market, and the history of cell phone is very revealing in this sense.
To summarize
Efforts of market leaders in electronic equipment, we came very close to the birth of a smartphone - a handheld device designed to combine a mobile phone and personal computer. Can he win the minds, depends on the quality of realization of the idea. And another one circumstance. Such a device like a smartphone, it makes sense does not in itself but as part of an information system. It must be provided appropriate services from mobile operators. Only in this case some time later we find in their hands telefonokompyuter smart - smartphone. The authors, translation:
