What is 1MB?
1MB is one of the measurements that are used for the data volumes. Content on a web site and flowing around the Internet (e.g. from your web site to the browser of someone reading a web page from your site) is measured in bytes. A byte is actually a very small thing e.g. one letter of the alphabet is about 1 byte big. So people measure things in multiples of bytes:
1 Kilobyte is around 1,000 bytes. Kilobyte is frequently abbreviated to ‘KB’
1 Megabyte is around 1,000,000 bytes. Megabyte is frequently abbreviated to ‘MB’.
1 Gigabyte is around 1,000,000,000 bytes. Gigabyte is frequently abbreviated to ‘GB’.
You don't really have to remember all this, but if someone technical starts using terms like ‘Megabytes’ and ‘Gigabytes’ you should know roughly what they are talking about.
How fast can I watch a video on you-tube, how fast could I download a songs or list of 750MB?
A user with the speed that is available through 3G can watch a video in real time. Also for the songs in you tube is the same. This is because the high Download rate that the 3G technology allows. In this prospective the user should be careful when opening videos and songs from you tube because they will consume large quantities of traffic very fast.
Let us have an exercise on how much time does it take today on 3G coverage to down load a song.
A song on average (if we take here for our example a song of an mp3 format) is 3.5 MB. This means that the user will need to consume 3.5 MB of traffic in order to have this song downloaded and stored in their device. So 3.5 Megabytes is the equivalent of 3584 Bytes and this is the equivalent of 28762 Bits. We need to have this since our speed of download is measured in Bits. (Megabit per second, Mbps).
So the above song will take 28762 / 2867 = 10 Seconds to be downloaded on 3G coverage. We can do the same exercise with the 750 MB. The time that is needed is 35 minutes to have this traffic in the device.
Is there a difference between upload and download speed?
Yes there is a difference between Up load and down load speed. The average difference is upload speed is ½ of the download speed.
Configuration - provisioning
For the 3G use the user does not need to have any special provisioning from the network. The customer needs to have a 3G capable phone and need to be configured for internet browsing.
In order for the customer to use Video call they will need to have the service provisioned.
3G vs. EDGE and GPRS
3G speed is 10 times faster than EDGE. EDGE is 10 times faster than GPRS. This means that 3G is 100 Times faster than GPRS.
