What is Cellular networks or Mobile networks? 


Mobile networks are can be say as cellular networks. cellular network could be a radio network distributed over land through cells wherever every cell includes a set location transceiver called base station. Have at the least one transceiver cell tower within their region, and use numerous radio frequencies.
Those base stations provide the cell with the network range which can be used for transmission of voice, text(sms), mms, and different styles of servicies these base stations are controled by telephone company wich provides these servicies to there user's Mobile networks is backbone of telecommunications, 


Frequencies of Mobile networks 


Cellular networks operate on completely different frequency bands together with the 450 megahertz , 700 megahertz , 800 megahertz , 900megahertz, 1800 megahertz , 2100 megahertz b, and 2600 megahertz Administrations generally issue "frequency band management rights" instead of individual licences per base station. Mobile operators will so manage and monitor the awarded spectrum themselves.A growing range of Administrations enable carriers to make your mind up that wireless normal to deploy (e.g. GSM, CDMA, UMTS, LTE or a mix of cellular technologies). this modern spectrum management idea poses new challenges to spectrum watching. the way to measure frequency occupancy, spectrum potency, licence compliance or spectrum interference?

2G, introduced in 1992, this is the second generation of Cellular networks
3G networks succeed 2G ones, offering faster data transfer
4G is the fourth generation Cellular networks.
