In recent years, there has been a plenty of paradigm shifts occurring in the way people across the world could connect and collaborate. Nowadays, wireless connectivity is almost everywhere and getting highly affordable even for people who are in the bottom of the pyramid. However wireless connection is liable for several changes and challenges and therefore is far more complex to implement and sustain than a wired system. Now, with the cool arrival of third and fourth generation communication technologies, the inhibiting trends such as unpredictability, signal fading, latency, jitter etc., are gradually disappearing for the good. The fourth generation (4G) wireless networks are all set to turn the current networks into end-to-end IP networks. With the massive adoption of IPv6, every single device in the world will have a unique IP address thereby IP-based devices, networks and environments are going to shine in the days to unfurl. This significant transition enables everything tangible in our midst to join into the raging Internet bandwagon in order to be remotely monitored, managed and manipulated. If 4G is implemented correctly and comprehensively, it will truly and tantalizingly harmonize global roaming, high-speed connectivity, and transparent end-user performance on every mobile device in the world. 4G is set to deliver 100mbps to a roaming mobile device globally and up to 1gbps to a stationary device. This allows video conferencing, streaming picture-perfect video and much more. The maturity and stability of 4G technologies therefore breeds innovation at faster pace and hence possibilities for novel and people-centric services are huge.
In this paper, we have highlighted the following critical issues for the leading wireless broadband standards such as WiMAX, Mobile WiMAX and 3GPP-LTE. This paper specifically discuss about the below-mentioned in detail.
- The evolution of mobile service from the 1G (first generation) to 4G (Fourth Generation)
- The configuration details of Mobile WiMAX and LTE.
- Benefits and usage patterns of these systems
Comparison and SWOT analysis for each of these standards in order to enable users to choose the best as per his requirements and preferences.
