Wireless tech was just an idea out on the paper when it started and now it has become one of the largest carriers of digital data all over the world. Today, this wireless technology made the functioning of several niches of industries smoother and faster.
Every enterprise, whether small or large have to depend on these wireless technologies thrive infrastructure. In coming years, wireless technology is set to include even more devices and features which would not even have been thought possible years ago.
Evolution of Wireless network-
The ability to operate devices thousands of kilometers away shows how wireless networks have evolved.
Growing demands for wireless spectrum-
Earlier, GDP of a country would tell how advanced a country is but now it’s measured on how much spectrum they have access to.
While the fourth generation, 4G, is still new to many nations, the telecommunication industry is already working on 5G that would be deployed soon. As this technology step towards perfection, the aim is that all devices will be wirelessly connected via 5G networks, making them commercially available worldwide. There is real and urgent demand for faster network, because of rapid and continuous growth of data traffic.
There is still more research and development needed to decide the aspects of 5G network, such as their industry regulations and technical requirements. Their needs decided include -connection speeds of up to 10 gigabits per second, and response time less than one millisecond.  5G networks will use which band of radio spectrum? And which wireless technologies are to be implemented to make this happen? These are some of the questions which are still into discussions? Makers of this network need to know which standards they will have to comply with, including lower rates of power consumption.
As, 5G network technology will speed up the data and bring low transmission latency which will not only benefit but also exponentially boost the Internet of Things. As more devices get connected such as self-driving vehicles, smart homes, automated robots, drones, telemedicine, household appliances, underwater applications and industrial automated machines- the requirement for new network technologies will increase. Billions of dollars are invested by many companies in color sensors, microcontroller, embedded software, smart chips, and telecom services with the idea of capitalizing on the interrelationship of the Internet of Things and 5G networks.
Li-Fi (Light Fidelity)
Advancement in wireless networks is Li-Fi, or light fidelity, which uses light signals to transmit data between devices. Li-Fi provides much higher speed than Wi-Fi, reaching up to 224 gigabits per second with transmission rates of one gigabit per second. No one thought that Light bulbs could be turned into wireless routers; this was just an idea before Li-Fi devices came into existence. In coming future, smart homes will be dependent on the Li-Fi technology as it is faster and secure because light cannot penetrate through walls, the signal cannot be hacked from a remote location.
Benefits to Communication
Since, Li-Fi is suited for reaching highly sensitive areas like mines that can eliminate disrupting sensitive equipment like technology found in hospitals. Li-Fi can act as a new alternative to Wi-Fi, providing an additional option for connectivity. It can help in relieving heavy traffic from cellular as well as Wi-Fi networks and service populated areas such as concerts, shopping malls, stadiums, and sport events.
Li-Fi has shorter range but faster speed than Wi-Fi. The further away from the light source, the slower the speed. However, there is limit to the range but this would provide security in communication and help in transferring information in a better and stronger way. The area of accessibility can be limited by the users, which will indirectly help them to keep the communications secure and private.
The future of wireless networks seems to be faster, smarter and more efficient. As telecommunication solution providers continue to improve the technology, more people will benefit from better and more secure communication. This new network technology will also bring speed to the many smart and connected devices boosting the ever-expanding IoT. There are no specific standards raised when it comes to next generation of cellular communication (5G) but Expectations are high as estimated speeds on networks in future will range from 3.6 GBPS to over 10 GBPS which seems more challenging.
