Clash (Mobile And Computers)

There is always clash between Computers and Mobiles. Whenever a phone call (or) even message(SMS or MMS) is received by cell phone which is near the computer, then waves are generated and the user can directly see that computer shivers (or) shows abnormal signs in monitor.



Reason is explained as follows :

Both Monitor and Mobiles are electronic wave emitting devices.

Thus when call (or) message is being received by mobile phone, then it generates radio waves.

These waves clashes with monitor and thus monitor screen gets shaked for while. If the mobile phone is kept at the distance from computer, then this problem wont occur.

If monitor is near the CVT transformers then also we can see the effect in monitors as the CVT transformers are also radio wave emitting devices.

Thus clash can be avoided by separating the two devices at some distance..

Mobile Technologies

Some Mobile Terminologies are being explained here

A2DP

A2DP stands for Advanced Audio Distribution Profiles.

For changing to high quality stereo audio from mobile phone to stereo headset,this technology is being used.
If we want to send audio from mobile phone to bluetooth headset,then this technology has to be updated.

GPRS

GPRS stands for General Packet Radio Service.

This Technology is being used as a way for getting Internet in mobile phone.
Using this technology ur, mobile phone will act as modem and when connected to PC,we can obtain internet connection in PC.
Data Transmission are done at a speed of 115 kbps.
In India however this much speed is not obtained.

EDGE

EDGE stands for Enchanced Datarate For GSM Evolution.

This technology offers internet connection to mobile phones with higher speed.
Data transmissions are done at a speed of 384 Kbps.
Thus the speed is 3 times more than GPRS based data transmissions.
This technology needs extra bandwidth but can easily transmit multimedia(faster and easier transfer).

HSPA

HSPA stands for High Speed Packet Access.

This technology works with base of 3G technology.
Thus it is sometimes refered as 3.5G.
Using HSPA, downloading rate of 14.4 Mbps and Uploading rate of 5.76 Mbps can be achieved.
These type of networks are currently not available in India.

DVB-H

DVB-H stands for Digital Video Broadcasting Handheld.

Using this technology,TV signals are being transmitted to mobile phones.
At present in India ,certain companies are using this technology.
But after the arrival of 3G,this service gets expanded or can be used in large scale.
