Idea Cellular Network provides different Idea online recharge packs with various permutations and combinations of internet data with voice calls and messaging services. Depending on one’s usage of the three factors, one needs to choose the suitable plan.
Here we discuss in brief the evolution of the different cellular technology over the years.
- It all started with the analog phones that used 1G or the first generation of wireless telephony back in 1979 and the early 1980s.
- The 2G or the second generation mobile technology was launched on the GSM network in Finland in 1991. These were the first digital phones.
The main difference both the cellular network technology is that the first one used analog radio signals and the second one used digital signals
- Then came the first 3G or the third generation technology in 2001 done by NTT DoCoMo in Japan. It worked on the W-CDMA technology.
The primary difference between the 2G and the 3G was the speed at which users could browse internet on their mobile phones. 2G offered a speed of 170Kbps whereas the 3G system could provide up to 42000Kbps.
- The fourth generation or 4G technology came into existence in 2010 with Sprint releasing the WiMAX phones in the US.
The basic difference between 3G and 4G is speed. A 3G network has to provide at the least a speed of 200 kilo bytes per second whereas for a 4G the network has to provide a minimum speed of 100 megabytes per second for high mobility communication and 1 gigabyte per second for low mobility communication.
An important factor that needs to be kept in mind is that every time there is an upgraded wireless broadband connectivity provided by a cellular service provider the user needs to change his mobile handset for compatibility reasons. A 3G phone will not be able to work using the 4G network though a 4G phone will be able to work using a 3G or 2G networks.
Hence, while using Idea online recharge to top-up your phone, remember to choose the correct plan as per your network’s connectivity and your handset’s capability.
- 4G has different forms –
- LTE, WiMAX and HSPA+ technologies.
- WiMAX is the short form for Worldwide Interoperability for Microwave Access that effectively provides broadband wireless internet connectivity over a large area providing speed levels between 3Mbps to 6Mbps.
- LTE is the shorter form of Long Term Evolution and is a competitor to WiMAX. LTE transmits radio signals whereas WiMAX transmits microwaves. The LTE networks are super fast, highly reliable and efficient and are considered the network of the future. All the cellular operators in India provide the 4G LTE network.
- HSPA+ stands for Evolved Hi-Speed Packet Access and is in fact an upgraded version of the 3G technology. It is certainly not a next-gen technology and is only a stop gap arrangement between 3G and 4G.
With Idea’s 4G LTE network enjoy browsing at great speeds by Idea online recharge.
