The Mathematics of Mobile Networks

The mobile phones is used in our everyday life, the demand on mobile phone networks has increased steadily. Today, among other things like desktop laptops, mobile phones are used to access the internet, watch TV, read emails and use social media. The initial networks were designed to only transmit phone conversations. As technology improved, they had to be upgraded to deal with huge quantities of data. The Shannon-Hartley theorem is central to planning in the mobile phone industry. This formula relates the theoretical maximum bit-rate possible for a mobile phone user to the available bandwidth as licensed by the Government and the radio environment of the user. The radio environment of the user depends on a number of factors, most importantly the distance from the transmission tower, the power and frequency used by the transmission tower and the noise or interference from unwanted transmitters. In addition, it takes into account the ambient temperature of the day. Using this data, the mobile phone engineers are able to calculate the theoretical maximum bit-rate possible for information to be transmitted to the user. Then this result can then be compared with hardware limitations to evaluate the maximum transmission rate experienced by the user.
