With Super fast 4G mobile data service both coverage and speed capabilities, we all wonder, what more 5G would do?? 5G is one of the most discussed technologies in this decade ,but do we really need it?? Yes, is my answer as I believe it’s the foundation for the next technological revolution. .. Let’s have a close look of what actually 5G is…
The next evolutionary step in mobile communication technology will hit the market by 2020 and is fondly called 5G. 5G simply stands for fifth generation and refers to the next and newest mobile wireless standard based on the IEEE 802.11ac standard of broadband technology, although a formal standard for 5G is yet to be set. The main difference compared with today’s 4G and 4.5G (LTE advanced) is beyond data speed improvements, it will be focused on IoT and critical communications applications.

Due to the increasing demand for wireless data communication, the available radio spectrum below 10 GHz (cm-wave communication) has become insufficient. The wireless communication industry has responded to this challenge by considering the radio spectrum above 10 GHz (mm-wave communication). The answer to increasing frequency congestion as Internet usage continues to rise across the world is provided by Light-Fidelity (Li-Fi). It’s a very exciting technology that has been on our radar since Professor Harald Hass gave a TED talk on the topic back in 2011. Continue reading “The Li-Fi: Internet Revolutioner”
Bluetooth is a current industry standard for short-range wireless connectivity. Bluetooth technology is widely used in consumer electronics for short-range wireless data transfer, like printers and digital cameras. It operates efficiently within the range of 20-25 ft in the environment without WLAN equipments. Bluetooth signals operate in the same frequency range as WI-FI (802.11b, g) standard. This is the biggest disadvantage of it because of its interference with WI-FI signals. A Bluetooth enabled device is not being able to function efficiently in the vicinity of WI-FI signals. Bluetooth technology took many years to come into mass market but still is struggling to really prove its potentials. Bluetooth faces major challenges by upcoming Ultra-Wideband standard which has many advantages such as higher data-rate and capability to co-exist with other wireless standards.
