Abstract
How did we ever manage without our cell phones? It is truly amazing to even think that there was a time not too long ago when we did not have our mobile handsets with us when we ventured out of our homes or offices. Let us try and demystify some of the technologies often related with our mobile phones that we get to hear often and understand very little of.
GSM or the Global System for mobile Communication is the most widely adopted cellular phone standards across the world. It is estimated that more than 80% of the total mobile phones in the world use this particular technology. The GSM standard requires the mobile phone to search for a GSM network or in other words there must be a compatible cell in that particular locality in order to use the GSM standard. The GSM standards apply to cellular networks, which are networks that operate on radio frequencies and comprise of cells.
