China Mobile Phone Step into the World - Autor: Angulo Fu

Thursday, March 18, 2010

When the cell phone first appeared on the Chinese market in the late 1980s it cost 10,000-20,000 yuan, and was the size of a brick. Regarded as the ultimate status symbol, it was called the da ge da, meaning very influential person. At that time, sales of mobile phones were under state control, and stocks were limited. Purchasers were required to place an order and make an 80 percent down payment. How things have changed! Mobiles are now available in multiple choices of size, color and function, on request.
China has become the world's largest mobile phone manufacturing base and consumer market. In the first quarter of 2008, the total mobile phone shipment in China reached 134 million units, increasing 34.5% year over year. While the subscriber base of mobile services reached 480 million at the end of the first quarter of 2008, which increased approximately 20 million when compared to the statistic data at the end of last year.

With expanding the industrial scale and quickening the pace of innovation, the entire domestic mobile terminal industry begins to step into the world, seeking new markets, technologies, capital and other resources for more development space. To cater to these demands, the IMIE'2007 has invited overseas buyers from 24 countries and regions, including 7 overseas mobile operators and 17 multinational purchasing delegations. Their purchasing lists include HSDPA/GSM/CDMA mobile handsets, PDAs, smart phones and other mobile devices, as well as components and accessories.

Representative Product
When it comes to affordable iPhone clones, Meizu seems to be leading the pack now that they've unveiled the pricing for their M8 cell phone. The 4GB model with built-in camera will go for 0 while the 8GB version will go for 0. The entry-level model (with no camera) will go for only 5 at 4GB and 5 at 8GB. Compare that to the iPhone's 9/9 price and suddenly Meizu's option doesn't look so bad, though it's still an iPhone clone.

Notifications to Your Workforce - Autor: ajeetKhurana

No organization can survive without letting its employees know about the major happenings. Employees should be knowledgeable about the various major decisions being made by the company. They should be notified about major policy changes. They should be kept aware of major contracts that might become their projects. They should be informed about the overall profits or losses being incurred by the company. In short, the employees of an organization should not remain ignorant of the major changes that might affect their work in the organization. Working people spend much of their lives in the office. So changes in the office scene might affect their lifestyles as well.

Of course, even on an everyday basis, employees have to be provided with notifications. These notifications would inform employees about all kinds of things. They could pertain to the dates of the next conference. The notifications could provide some extra information that might seem interesting to various groups of employees. The notifications would be a great help to a group of employees. The notifications could also alert employees to the possibility of an emergency and instruct them as to how they would be required to cope with the situation. Notifications have a major role to play in the functioning of an organization. Hence, no organization can afford to neglect this.

There are various ways whereby an organization can let its workforce know about important issues. There is the good old business meeting in order to inform a specific group of employees. There is also the option of going to each person separately and informing them. However, the latter can be rather time-consuming and impractical if the group to be informed is not small. Moreover, these days we have access to a variety of economical and quick modes of notification. Two of the most popular among these are the email reminders service and the text messaging service.

Thanks to our being logged on to the Internet, email reminders are a great option. They are fast and they allow one message to be sent to many people at a low cost. However, when the notification is a little more urgent, it is good to subscribe to an emergency notification service that helps send out SMSes. Our tendency to never leave home without our mobile phones ensures that we will get the notification at the right time. When looking for a suitable alert and notification service, every business organization should be looking for one that supplies the best technology at the cheapest prices. Given the competition, that shouldn't be hard to find.

Knowing Your Cell Phone - Autor: robertoms2003

No one doubts that cell phone is one of the most used consumer electronics worldwide. But have you ever asked yourself how does a cell phone work? What is a cell phone?

The amazing fact about a cell phone is that it is a radio - a very special one. The gurus in the line are Bell (1876), Tesla (1880) followed by Marconi and Bose (late 19th century). It is known that the concept of cell phone was produced by Bell Laboratories with the permission of FCC (Federal Communication Commission), and had everything to do with broadcasting and sending a radio message out over the airwaves.

In cell phone technology cells divide the city, allowing for the facility to be frequently reused throughout the city. Millions can simultaneously avail of it.

In devices that are half-duplex (walkie-talkies and CB radios) two communicators use a single frequency. This means that at a single point of time only one can talk. On the other hand a cell phone being a full duplex tool has two frequencies: one for talking and the other for listening. Thus a real-life conversation can take place. Cell phones glide through 1,664 channels whereas the walkie-talkie group has to be content with only 40. The walkie-talkie and the CB radio respectively reaches out to 1 mile and 5 miles but the cell phones, because of their ability to switch from cell to cell can cover incredible distances, even while driving at top speed. Each cell is approximately 10 square miles.

The cells are usually depicted as hexagons. The unique frequency tiers avoid all possibilities of cross connections. Generally a carrier of cell phone can avail of 832 radio frequencies in a city. Each cell phone uses 395 voice channels (per carrier), that is 56 voice channels per cell. It means 56 persons can simultaneously say hello on the phone. In digital transmission technology the number of channels increases even further. For each cell phone 168 channels is available.

The distinctiveness about cell phones is their low-power transmitters. Most use 2 strengths: 0.6 watts and 0.3 watts. In comparison it is 4 watts for CB radios. The advantage of this is that it can be frequently reused consuming less power. Cell phones are battery operated. The lower the power the smaller the battery. This makes the set handy and light.

For cellular technology a city requires a good number of base stations. This can run into some hundreds of towers. But because of the huge number of users costs per head remain very low. Each carrier has one centre called MTSO or Mobile Telephone Switching Office. Its work is to see to all the connections.

Cell phones each have codes, which enable identification of the phone, its user and its server. When someone tries to reach a phone the first thing is to locate the SID (system identification code) on the control channel, that is find out if the phone is within range or not. A message relays no-service when it is out of range. But when the SID is received then the next step is to find out whether the call is within its own home zone or not. The phone also tracks the location of the phone called on a database. Thus the MTSO knows the cell of the called number and caller. Communication is transmitted through the control channel and it is this link that activates the phone being called and calling.

These are the facts of a cell phone as explained for a layman. It is always advisable to know at least the basics of a cell phone since it has become an integral part of our life.

SMS messaging or the short message service messaging is a very popular mobile interaction method these days.

Due to its low cost nature this service is highly popular among the teenagers these days.

First you have to know some important facts and trivia about the SMS messaging service. Basically the idea of SMS messaging was come in the early 1980s. But this service was come to an effect in 1985 for and to GSM mobile handsets only. After that it became available for each and every telecom technology like CDMA, AMPS, Satellite phones and even Landlines too. Surprisingly, some online messengers are also providing the messenger to mobile and mobile to messenger SMS facilities. Basically SMS is a short message of at most 160 characters, which can be written by using mobile keypads in general. It can be sent from a mobile to another mobile. To overcome the limitation of the 160 character limit the Long message service is also there. Long Message service is nothing but the collection of some SMSs. Basically a Long Message of more than 160 character uses to divide itself in some 160 character SMS. Then each and every 160-character phrase sent one by one to the receiver’s mobile phone. Generally all the digital mobile phones do have the feature of short message service option.

Due to the improvement of SMS some monophonic ring tones can also be sent through SMS using some special format. Later the scope of SMS was increased and the technology enables the man to send likes of pictures and video clips using GPRS system from one mobile set to another. But this service is named Multimedia Messaging Service or simply the MMS. But now it is possible to do something like MMS through SMS. The SMS can be sent in special text formatting in likes of bold and italics. Also some icons, animations, sound effects, pictures, and special ring tones can be sent through SMS these days. This type of Short Messaging Service is known as Enhanced Messaging Service or simply the EMS. According to the researchers this EMS service is the intermediate stage between the SMS system and the MMS system. But this EMS system seems to grab some rapid popularity!

Now, the following statistics about the Short Message Service seems to be really interesting. In 1995, the initial stages of SMS, each and every customer used to send a SMS once in every two and half month. Again, in early 2000s each and every customer was sending some 30 to 40 SMS in every month. Again some 9 Million SMS were sent among the mobile users in the very first day of 2007 that’s too only in UK!

Short Message Service is too much successful due its low cost nature. Again you need not to reply at that instant when you receive the SMS. These are the some of the facts that makes the SMS really popular.

Some literature minded people do believe that the short nature of words will kill the art of literature some day. But to people, interaction is more important than the literature. So here is the high possibility the progress of the SMS system will continue.
