Mobile technology has already creating hype through out the world. We are using so many features in our mobile these days which most of us have never dreamed off. What is making all these amazing features working so well? We are using SMS, deliver messages in seconds through out the world with just a little click of button”Send”, MMS, sending pictures and video files in amazingly quick time, finding locations, accessing high speed internet in your mobiles are the features which were not possible just few years back, there are some technologies which are actually responsible for such facilities on our mobiles and we are going to talk about all these technologies in mobile communication section.
Every body knows about mobile phones, these are different size portable devices capable of communicating over longer distances through high tech processes involved know to be mobile computing and communications.
Today’s mobiles networks supports features likes SMS, GPRS, MMS, emailing facility on mobile, Bluetooth, WAP and many more depending upon how reputed and bigger mobile network company is, most of the networks world wide provides these features as they have become the standard features in mobile communication between their customers and of course one cannot neglect how sophisticated mobiles phones are available now, these mobile phones carries many features which some times are not supported by mobile networks. Mobile phones of today’s age are now equal to portable PCs. These mobile phones connect to their cellular networks and these cellular networks are connected to Public switching telephone network (PSTN).
Mobile Network Technology
Mobile Technology has groomed a lot in past few years, major reasons for rapid advancements in mobile network technology is requirements for being mobile or connectivity on move. Latest mobile handsets offers features which one had never thought off, ultimately it forces mobile network companies to bring these features in practice use to take commercial advantages.
Cellular companies use AMPS, D-AMPS, CMMA2000, UMTS, GSM, EVDO etc. AMPS however pretty much vanished from the scene, AMPS network system was based on analog communication technology, latest features were not supported by AMPS therefore all cellular networks world wide have adopted above mentioned digital communication methodologies to meet the need of consumers. GSM remains the highly used mobile communication methodology worldwide. Cellular networks and mobile phones vary from geographical locations and providers to providers, but still standard communication methods are more or less same every where. Basic communication takes place using electromagnetic microwaves with cellular base stations. Cellular networks have huge antennas normally located in the middle of certain area to provide optimum signal broadcasting. These antennas are known as Base Transceiver Station (BTS). Mobile handsets have low powered transceivers which transmit voice data to the closed BTS which can usually be with in 5 t 8 miles radius.
Transceivers: Transceivers are devices which have capability of transmitting and receive data at the same time.Mobile handset register it self at mobile network switch or exchange as soon as it starts transmitting, usually it means when handset is turn on, it tries to registered to the network of inserted SIM card. Mobile networks uniquely identify each and every registered mobile handset on the given BTS and sends notifications to those mobile handsets which have incoming calls. Handsets will always be registered to the most nearest BTS for communication, incase if user of the network is on move, mobile phones in this case will handoff to many closest BTS during the call and keep the connection alive with nearest base stations. In case of unavailability of BTS, handset will be disconnected from the network resulting in dropping of on going call.
BTS also operates on less power radio frequency transmission; they make their presence feel by broadcasting signals for receivers of mobile handsets. Communication between BTS and mobile sets takes place in stream of digital data, which is digitized audio. Each mobile network operates on unique radio frequency.
