• • 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.

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.

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.

– 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.
