[Interview] Yoo Ho-sang, CEO of Inonnet

"The Fourth Industrial Revolution Is for Everyone… Even People with No Money Must Use the Mobile Telecommunications"

The so-called 'fourth ISP', which is short for 'fourth mobile ISP,' has long been a dream of the workers in the information and telecommunications industry. But the companies that actually tried to make four were drank or mocked. Even three mobile carriers, such as SK Telecom, KT, and LG U-plus, are fiercely competing to survive in the market.

This concern came when the first news was announced about Innonet, which had challenged four cases since the regulation on entry into the telecommunications business was eased from the licensing system to the end of last year. However, Innonet's pursuit is far from taking away subscribers from existing three carriers. Rather, the three mobile carriers directly do what they haven't tried before for business reasons. The formula 'small but strong company' is suitable for Innonet, who has dug into niche market with innovative ideas.

Innonet is a SME established in 2011. It aims to bridge the IT gap between urban, rural and rich and poor based on its flagship technology, 'TV White Space (TVWS)'. It also seeks to solve various social problems by applying it to public safety services such as disaster safety nets, buses and ships. △ 2015 Radio Broadcasting Technology Award (Minister of Science and Technology Information and Communication) △ 2016 Radio Broadcasting New Technology Award (Prime Minister's Award) △ 2017 Presidential Award In April, the company applied for an empirical special case with the `` Internet of Things Service for Remote Vehicles Using UHF TVWS Technology. ''

Smart Farm is one of the eight leading innovation growth projects selected by the government during the Fourth Industrial Revolution. Smart Farm refers to a farm that automatically maintains the growth environment of crops and livestock by applying ICT technology to a plastic house or barn. The government announced the budget for 2020 on August 29, and increased the budget for the full-fledged expansion of smart agriculture from 36.7 billion won this year to 385.7 billion won next year by 25.8%.

However, due to the burden of the network construction, there is a limit to the introduction in the real farm. TVWS is drawing attention as a technology that can overcome these limitations. In addition, the introduction of TVWS is expected to bridge the IT gap in the islands.

After completing the construction in 18 counties in Jeollanam-do, Innonet is currently discussing business with Sacheon City Hall, Gyeongju City, Gangwon-do City Hall, Gimpo City, and Seocho-gu Office. In South Africa, Nigeria, Libya, the Philippines, and Kazakhstan, the company is discussing business with TVWS-based Internet service and bus public Wi-Fi.

UPI News sat down with Innonet Representative Yoo Ho Sang at the Innonet conference room at the Hyundai Knowledge Industry Center in Songpa-gu, Seoul on the afternoon of August 23. Yoo said, "The core of the Fourth Industrial Revolution is to make mobile communication services available to those who have no money." That is why Yoo started his business. Next is a question with Yoo.

What is the flagship business, TV White

"There are empty channels between the digital TV frequency band 470 MHz (MHz) and 698 MHz. If you use channel 14 in Seoul, the channel is empty in Gyeonggi-do, where it is not used. This is called TVWS." This channel is empty and not intended for communication, and it is very fast, going up to 10 kilometers (km), and wireless is said to be high speed if it is more than 2 megabits per second (Mbps). Innonet is transmitting at 26Mbps, and communication is possible even in places that are blocked like mountains, which is particularly advantageous in the mountains where the mountain is only a few kilometers away.

Throwed a vote for the fourth mobile communication

"The biggest problem with the existing four carriers was just using LTE. There's no distinction from the three mobile ISP now. Fourth ISP should be differentiated. The Internet of Things and the speed of With public Wi-Fi and camera technology becoming vital, smart farms are all surveillance technology, which is extremely expensive because it's all wired, and people don't like plugging all the equipment into their telephone poles. The only thing you can do wirelessly in the country is TVWS, where you're competing with LTE, which usually costs US$70 per 10 gigabit (Gbps). If you calculate the LTE plan, it will cost you US$4.2k for 10 cameras. Do not enter. That's why TVWS is required for Smart Farm, Bus. "

Where and how is TVWS installed

"It's called TVWS Gateway. By 2017, more than 14,000 town halls were installed with optical cables. The economy was low. The Internet was required in the countryside and so the government and KT invested 50% and 50% for fiber optic installation. Even if it is installed until the town hall in the village, it can't be driven if it is 400 meters away from the village, but it is usually over 2km to build a barn, it costs about US$10,000 per kilometer, and it's unsightly. In addition to the network capabilities, the temperature and water quality sensors was required. If we add the equipment separately, the cost increases and the maintenance cost increases. The cost is only one-tenth because of being integrated.

Smart farms are usually large ?

"No, I also need to use it comfortably in my facility. If you raise a cow, you have to stay out for a month and watch it. A person needs to be there." If you find that you have red tide in the farm, you can release the fish, and if you have a sensor, you can get compensation from the government. When using LTE, It costs US$250 a month. If paying US$5,000 won as TVWS installation cost, but if you already have internet in your home, you won't incur any additional charges besides the internet. "

What did you apply for in this case?

"There are two types of TVWS, fixed and portable. The fixed type is 10km and the mobile type is 600m. The mobile type has many available channels. However, TVWS, which is capable of point-to-multipoint communication, allows both short-range and long-distance equipment to communicate at the same time, so that the available channels do not change even when applied to cruise ships and passenger ships with fixed travel routes.

If the Sewol cruise ship was also in real time control, the situation would not have been so. LTE does not allow real-time control due to cost issues. It is all related to the communication fee. "With TVWS, we can provide Wi-Fi services without worrying about costs, enabling real-time control on cruise ships."

What about disaster network

"It's the same with the disaster network. It costs a lot to spread across the country. Carriers need about US$5 billion to install nationwide. That's an answer that the government doesn't want to pay with taxes. Innonet has created a backpack-type mobile base to connect with wireless backhaul, which is already patented in the US and patent pending in China and Europe. "

How do I connect in a mountain that is not communicating or in a collapsed subway

If the existing disaster safety network is used by rescue workers, the backpack / carrier TVWS CPE and relay developed this time have been developed to provide the public with an emergency network for disasters, LTE shadow areas, and public Wi-Fi at the venue.

The repeater only amplifies the signal. But, the relay demodulate the data through the modem and then retransmits it. The advantage of connecting the backhaul to TVWS is that it can send at high speeds, even at low frequencies. Previously, there was no sub-giga frequency which is wideband for high speed. The product could not come out. The higher the antenna band, the sharper the beam. The beam is sharp, so when these things move, they can't focus. With TVWS, even if the frequency is low. This is a 360 degree beam pattern. Like the village bus mentioned earlier, it's good for moving vehicles. "

Why did you do TVWS?

"It was a coincidence that I did TVWS for the first time. I tried to make an instrument and it failed. When I started it in 2011, it was requested by an acquaintance. I made it without considering labor costs. At that time, work was more important. TVWS has been spreading since 2013. Since then, TVWS products was developed with a cable TV consortium.

After the government have published a case-study in Europe, and Microsoft has been contacted directly. Microsoft buys products directly from manufacturers. Almost no Internet is available in the central part of the United States, and TVWS is set up to provide Internet service for $ 8 or $ 10. Globally, Microsoft buy TVWS and apply to Africa. I hope to join with MS if possible.
