From the early stages of the analog mobile generation 1G to the last implemented fourth generation 4G there has been a huge paradigm shift. The new generation does not focus on improving the voice quality but tries to give the subscribers access to global communication reality. The mission is to reach communication ubiquity and enable the users to be connected 24/7. The constant growth of mobile phone users has led to the saturation of voice-oriented services.
All 2G services were voice-centric services; the Short Message Services (SMS) brought texting into limelight as it permitted a text message of 160 characters to be viewed and sent via your handset. 2G system also supported data but with terribly slow speeds.
Then came the third generation or 3G, the sole purpose of this technology was to create a new protocol to enhance the smartphone experience. The 3G connection can be established in an automobile while travelling or even in a train. Download speeds of this technology is 144 kbps while commuting, 384 kbps while walking and 2 Mbps for stationary users. The 3G connection won’t change in the future but the existing framework will be made better. The very definition of 3G is an umbrella not a single standard.
The latest and the fastest is the fourth generation or 4G, which has a new framework and is trying to accomplish new levels of user experience by combining all mobile technologies that exist, General Packet Radio Service (GPRS), Global System for Mobile Communications (GSM), Wireless Fidelity (Wi-Fi) and Internet Mobile Communications (IMT-2000). The main agenda of a 4G network is to achieve a multi-service platform, low-bit cost and ubiquity.
Low-bit cost is vital, as high volumes of data will be transmitted in the given scenario over a mobile network. Video transmits high volumes of data, which is now a part of every high-end application. You can’t surge the rates of bits as it will be an expensive affair attracting minimal subscribers.
4G phones should also have a multi-service platform as it is the main reason for user transition and will telecommunication operators access to new levels of traffic.
Ubiquity means that mobile network should be omnipresent for the subscriber to utilize. This means that transmitters should not only be available on our phones, but also on the smart watches that monitor our vital signs, in cars and packages to know about its whereabouts 24/7.
In spite of all the evolving technologies the final success of new mobile generations will be dictated by the new services and contents made available to users.
