Mobile Generations – 4G

    • Introduction:

2G, 3G, 4G are the wireless networks available till today. 4G is the successor of 2G and 3G wireless networks. In simple words one can say it is an improvement in the wireless technology. Telephone Calls, Emails, Internet access, GPS Signals all of these mobile technologies use one of these wireless networks to function, to communicate with each other and to the internet.
In 2011 most of the service providers and the cell phone manufacturers have advanced to 3G technology, providing the increased data transfer rate hence making it easier to access the internet from the mobile devices and access applications like video calling, mobile games etc. 3.5G increased the data transfer speed from 3G’s 3Mbps to 14.4Mbps (peak speed) with the HSPA – (High Speed Packet Access) standards. Both the HSDPA & HSUPA come under the HSPA technology.
But after the release of 4G capable devices like the new iPad from Apple and many other smartphones, many service providers have begun to offer the 4th Generation wireless networks to the users for making the communication much easier. 4G could be found in all of the models of Samsung Galaxy Tab.

    • 4G Features:

4G uses the Digital Broad band Packet for the data services and Voice over Internet Protocol for Voice communication hence increasing the overall throughput.
There are two Technology standards to provide the high speed access – Long Term Evolution (LTE) and WiMAX – (Worldwide Interoperability for Microwave Access). Mobile Service Providers use one of these two standards to deliver the required speed to achieve the 4G goodness. It is said that after using 4G network the internet can be accessed at a speed (> 100Mbps (peak)) which was not possible before on the Mobile devices. Reason for transiting from basic Analog to such high speed Digital Technology in mere 25 years is the continuous improvements in the semiconductor technology which is an extra ordinary achievement.

    • What are the advantages of 4G:

Variety of multimedia applications will be supported like
– Multimedia Conferencing
– Video Phones
– Video-On-Demand (VOD): Means users can select, watch the videos on demand
– Streaming high definition movies
– Multimedia messaging

– Graphically intensive games can be played online with multiplayer possibility.

Next generation 5G will be including the Giga bit data services.

Mobile Generations – 0G, 1G

You might have heard the word Generation referred as ‘G’ indicates the evolution in the Cell Phone Technology with respect to the time. In the other way we can say the Transformation of the Cell Phone from just a Wireless device into a full featured Smartphone.
There are 4 Generations available till today and another generation i.e, 5G is planned for the next decade 2020 which contains a very advanced requirements & features. Some samsung galaxy tab have 1G built into their features.

I am gonna explain all these G’s in briefly, so let us start from the –

    • Mobile Radio Telephone (0G):

“Over” and “Out” were the two famous words in this generation.
Hope you got what i am technically trying to convey. It simply means only one person can talk at a time using the Push to Talk(PTT) feature also known as Press to Transmit. The conversation used to take place on half-duplex communication lines, using a momentary button to switch from voice reception mode to transmit mode. Hence these two words were used to indicate the transmission is complete from one end so that the other person can reply for it. 0G devices were built in the year 1946 by Motorola and Bell System and these devices used the Mobile Telephone Service to connect to the calls. It means an operator helps us to dial and route the call. Now a days we install Music Systems in the car but in those days the whole Phone-unit was installed in the car.

    • 1G:

Before going further let me give you an example for the Analog signal. Whenever we speak a sound wave gets generated which is a form of Analog signal. 1G devices used the analog technology for the communication which includes the communication on certain frequency band (FDMA – Frequency Division Multiple Access). The conversation was a full duplex meaning both the persons can talk & listen at a time. Device was equipped with direct dialing hence operator help was no more required to connect to a call. The system was able to handle the billing, roaming and call setup functionality. Companies like Nokia, Motorola built such devices in the 1970 decade but it was first commercially used around 1981.
Text messaging was also possible in this generation with some sophisticated devices. Since the whole technology was based on the analog system noise introduction into the signal during communication was a disadvantage. In the current days this generation’s system & devices are no more used.

How to use Mp3 Cutter on Android Smartphone?

Do you just love a part in the whole song? Want to use the best part in the music as your ringtone? Or want to cut the unwanted part from the song? Then here is a wonderful android software application called as Mp3 Cutter which fulfills your needs and that too for free.

Mp3 Cutter from beka is one of the top free android apps which cuts any part in the song based on your wish and stores it into the phone’s memory. It works on the Smartphones, Tablets running on android version 2.0.1 and up. The app is quite stable and easy to use. This app supports .mp3 files only.

To download Mp3 Cutter, open the Google PlayStore and type “Mp3 Cutter beka”. Select the app and install it, the size of the app is just 745KB. Before using this app I recommended you to install the File Manager app. Because the Mp3 Cutter stores the edited part of the song in the “/media/audio/” location of the phone memory which can be accessed easily using the file manager software. The reviews say that Mp3 Cutter can be used on most android smartphones.

Steps to cut the song using Mp3 Cutter:
– Open the Mp3 Cutter App, click on the green button placed on top.
– Browse and select the song from your phone. The song gets loaded in the app.
– Now the app just looks like a player app with some extra buttons. Extra buttons includes a red button and two sets of ‘<>‘ buttons. The first set is used to trim the start point and the second set is used for trimming the end point of the edited song. More explanation on this in next step. The red button is the trigger/halt to cut the song.
– Click the play button to play the song. And when your best part starts playing just click the red button which starts to cut the song. Clicking the red button again will stop the cutting of the song.
– Clicking the Reset Cut button aborts the cut part and starts again for fresh edit, Play Cut plays the edited part of the song and Start cut saves the edited song.
– If you find that the edited song misses some part of your favorite music then this is where the two sets of ‘<>‘ arrow buttons are used to trim the edited part.
– Open the desired location (“/media/audio/”) in the file manager to find the song which can be copied/moved to another location in the memory and can be used as a ringtone, can be shared or deleted etc.
