5G Mobile Network and IoT

5G is a new network system that has much higher speeds and capacity, and much lower latency, than existing cellular systems. 5G networks will use a type of encoding called OFDM, which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE.

1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.5G planning aims at higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, more reliable, and massive machine communications.

Following requirements that a 5G standard should fulfill:
• Data rates of tens of megabits per second for tens of thousands of users
• Data rates of 100 megabits per second for metropolitan areas
• 1 Gb per second simultaneously to many workers on the same office floor
• Several hundreds of thousands of simultaneous connections for wireless sensors
• Spectral efficiency significantly enhanced compared to 4G
• Coverage improved
• Signaling efficiency enhanced
• Latency reduced significantly compared to LTE.

5G Race
The vision of 5G is becoming clearer as we move closer to 2020. Most experts say 5G will feature network speeds that are blazingly fast at 20 G/bps or higher and have a latency that is mere milliseconds. Not only will people be connected to each other but so will machines, automobiles, city infrastructure, public safety and more.Some operators are attempting to be very aggressive with their deployments and push the standards process forward. In the U.S. Verizon has formed a 5G Tech Forum along with other vendors like Cisco, Ericsson, Nokia and Apple. The group’s goal is to collaborate on early 5G specifications and then contribute those to the 3GPP. Verizon released its specifications to vendors in July 2016. Meanwhile AT&T’s tactic is to not release its own specifications but instead to try to speed commercialization of 5G once the 3GPP releases its first official specs, expected in mid-2018.

The following are some of the “revolutionary” changes to be expected in the 5G mobile networks of the future:
• Super High Speed Connections and Broader Capacity – Obviously, the new generation of mobile networks will have to be fast—a blazing fast speeds that will make wireless connections the more preferred option.
• Overhauling and Harmonization of the Radio Spectrum – This should lead to more efficient wireless interconnections among a wider variety of devices.
• Greater Network Reliability – Advancements in antenna technology are expected to bring an end to undesirable abrupt connection drops.

The United States
The Federal Communications Commission’s (FCC) Spectrum Frontiers Order has laid the groundwork for the use of 5G technology in the United States by 2020.In July 2016, the FCC began creating rules for 5G technology, making the United States the first country opening high-band spectrum for the technology. Because the spectrum bands are available for licensed, unlicensed and shared users.

South Koria
South Korean carrier KT Corp. (ADR) (NYSE: KT) plans to launch a 5G network during the Winter Olympics in 2018. The company completed a successful trial of a system from NEC Corp. (TYO: 6701) using extremely high frequencies for transmitting data at up to 3.2 Gbps (gigabits per second) in the Taebaek Mountains, where the 2018 Olympics will take place.

China
China is set to have 5G technology commercially available in 2020. However, because Chinese authorities control the implementation of the technology.

India
The government is also laying much focus on 5G and is working on to create a Rs 500-crore fund for the development of the technology. A high-level committee under the chairmanship of the Telecom Secretary has also been created to work on a roadmap for the proposed roll-out of 5G by 2020.India is looking at 5G as a major opportunity in terms of offering the kind of services that rural India needs, including tele-health and tele-eduction services. along with bandwidth-heavy applications that can drive development and 5G is expected to play a big role in that.
The telecoms industry is at an early stage in the development of 5G. There is still much life left in LTE networks with a wide range of standards compliant network features being developed by vendors and deployed by operators that improve the performance of LTE. But analysis of major trends by many in the industry has led to a consensus that evolution of LTE needs to be complemented with a radical change within the next few years in the fundamentals of wireless networks a generational shift in technology and architectures and business processes in order to ensure the industry continues to meet market demand for wireless services as they evolve, and to stimulate new economic and social development
