5G Technology- Next in line!

There is so much conversation, rumors about 5G in the media, social networks and curiosity about what their characteristics will be. In the midst of so much exaggeration about IoT (Internet of Things), news about Smart Homes, Smart Cities, in some places IoT laboratories have been established. You can understand the IoT by imagining a refrigerator that can give alerts about any item of the day such as butter / bread that needs to be replenished and, therefore, place the order automatically in the supermarket without human intervention. In the same way, the AC and the water heater of the house are turned on when the owner leaves the office to the house. All this could be possible through the implementation of 5G.

The next in the Technology -5G row will be launched in 2020 at the Tokyo Olympics. Japan has decided to carry out the live broadcast of the Olympic Games through 5G. Therefore, there are extensive tests and trials. The test is carried out in many countries such as USA. USA, France, Japan, China, Germany, etc. There is a test bank at IIT Delhi established by Ericsson.

Before continuing to investigate, it is important to first know about the 4G deficiencies that are currently being used. After all, it is pertinent to know the need for 5G and also the high data rates.

The main deficiency of 4G is that it is a comparatively low data rate; We can reach a maximum data rate of up to 24 Mbps in our mobile phones through the air interface. In addition, signal strength and data speed are further reduced within buildings in areas such as bathrooms, basements, etc. Therefore, there is a need to improve indoor coverage, the reliability of the network.

All right! How to address the weakness of 4G? 5G technology has the answer. By setting the following goals for 5G:

• Data rates of 1-10Gbps for subscribers or UE (user equipment), endpoints
• One (01) end-to-end delay (latency) of milliseconds
• 1000x bandwidth per unit area compared to the present
• 10-100x number of connected devices compared to current use
• 99.999% availability (user perception).
• 100% coverage (user perception).
• 90% reduction in power consumption / use of the network compared to 4G
• A battery life of up to ten years is expected for low power machine type devices;

This technology seems to be more appropriate to address the growing relevant needs of future generations.

The 5G spectrum has been identified around 6GHz, 24 GHz, 40 GHz. The development of it in process to meet all the above objectives.

It is likely that 5G will bring high data rates, download speeds, greater network bandwidth for backward connectivity from eNode B to MSC (Mobile Switching Center).

The research is in full swing to present more detailed features in the Internet of Things (IoT). There are, and there will be more smart homes, smart cities, smart offices functioning in the near future. In addition, the testing process is also underway to develop autonomous vehicles / drivers without cars.

First, the phones enabled for 5G will be available by mid-2019.

Another segment to attend is the improvement of the batteries. We are currently using lithium ion batteries that have a useful life of approximately 1100 to 1200 charging and discharging cycles, which is equivalent to three years of battery life. In addition, the lithium-ion battery is expensive, heavy and slow. Therefore, a considerable improvement in battery technology is also required.

Meanwhile, with the increasing and continuous use of techno-enabled devices around humans, it will also cause damage to health. Due to the emission of continuous radiation, pollution by electromagnetic noise will increase. This can further exaggerate the associated health risks. Therefore, every human being should take adequate precautions while using the instruments for a prolonged period. It is also important to keep the radiant device away from children. Until the new findings arrive, we must ensure that the technology creates only a win-win situation to improve the comfort and efficiency of our work process.
