Why Telcos Need To Adopt 4g technology?
Over the past ten years mobile communications have transitioned from a luxury item to a utility as critical as electricity and water. As operators eye the incredible growth and hence strain on their networks, they must ponder the question: When and how do I make the move to 4G for wideband internet? It's no longer a question of 'if', but more a question of "when" and "how".
However, I think this is not a technology decision, it's a business decision.
Before I put forth my views, let me first summarize the technological improvements along with various features from 1G to 5G.

In the 4G wireless networks, each node will be assigned a 4G-IP address (based on IPv6), which will be formed by a permanent “home” IP address and a dynamic “care-of” address that represents its actual location. 4G wireless network, use IPv6 transmission protocol along with digital modulation techniques like Orthogonal Frequency Division Multiplexing (OFDM), which transmits large amounts of digital data over a radio wave. OFDM is able to compress a lot more data packets through less wireless spectrum’s. 4G also use multiple antennas in their radios which improves for better signal reception as well as decreasing latency.
Voice over HSPA (VoHSPA) enables voice calls to be delivered more efficiently from a spectral standpoint over Packet Switched (PS) rather than Circuit Switched (CS) networks freeing up radio resources for additional data traffic.
A device can achieve a speed of 100 Mps. Available technologies for 4G are WiMax (Worldwide Interoperability for Microwave Access),LTE (Long Term Evolution). In 4G, Portability is increased further. World-wide roaming is not a distant dream. WIMAX is better choice as next generation mobile broad band service.But, LTE is the choice for real global service.
Here is an infographic on 4g speed using WIMAX & LTE
The idea of WWWW, World Wide Wireless Web (5G), is started from 4G technologies. The following evolution will based on 4G and completed its idea to form a REAL wireless world. Thus, 5G should make an important difference and add more services and benefit to the world over 4G; 5G should be a more intelligent technology that interconnects the entire world without limits.
Currently there is no 5G technology deployed. It’s expected to arrive around 2010. I hope this article help you to understand 3g vs 4g from technical and feature’s perspectives.
Next article, my views on drivers for selecting right technology for 4G for fastest mobile broadband network. Here is an interesting article on 7 Reasons 4G is Better Than 3G ,

| Evolution of wireless technology in last 30 years |

- 1G was only for voice communication. It was introduced in the early 1980s
- 2G was introduced in late 1990. It was planned mainly for voice transmission with digital signal and the speeds up to 64kbps. Facility of roaming was introduced.
- 2.5G introduced GPRS .
- What is 3g?
3G used wide brand wireless network which increases clarity and gives the perfection as like that of a real conversation. The data are sent through the technology called Packet Switching .Voice calls are interpreted through Circuit Switching.
Not only these but also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, Multi Media Messaging Service (MMS), 3D gaming, Multi-Gaming etc are also available with 3G phones.
3G operates at a range of 2100MHz and has a bandwidth of 15-20MHz. Technologies are CDMA 2000, UMTS, EDGE. Latest technology HSPA & HSPA + 3.5G supports higher throughput and speeds to support higher data needs of the consumers
