At the 2016 Asia Broadband Forum, Goran Berntson, director of industry development of Huawei LTE, delivered the keynote speech "WTTx ushering in a New era of Mobile Broadband connection". 

He elaborated that WTTx (Wireless to the X) is a very important part of the national broadband strategy, which provides high-speed wireless broadband access services comparable to optical fiber, provides excellent mobile broadband experience for end users, and helps operators to open up new business opportunities for wireless broadband. 

With the rapid development of information and communication technology (ICT), most people think that the Internet is everywhere, but this is not the case. 

On the earth we live in, most people are still faced with a world that is not connected to the Internet. 

According to a report released by ITU, only 34% of households in developing countries had Internet penetration in 2015, and nearly 1 billion households were out of the net. 

In Asia, home Internet penetration is only 39%. 

ITU hopes to connect more than 300 million homes to the Internet by 2020, which requires the communications industry to come up with reasonable solutions to achieve this goal. 

In densely populated areas with good economic conditions, home broadband access usually uses copper wire or optical fiber (FTTx), which can provide stable and fast broadband services. 

However, the more the cable access goes to the rural and other remote areas, the more difficult it is to develop and deploy, and there are some problems, such as high cost, long construction cycle, high maintenance cost, poor investment profitability and so on, which are not suitable for underdeveloped areas. 

At the same time, due to the problems of land ownership and road rights in many overseas countries, the deployment of cable broadband is extremely difficult, the progress is slow, and some buildings and properties are unable to move in. 

WTTx is a wireless broadband access solution that Huawei proposes to provide fiber-like FTTx experience based on the broadband market demand. It provides home broadband services through wireless broadband technology, giving full play to the characteristics of wide wireless coverage, rapid deployment and fiber-like experience. Under the premise of satisfying home broadband services and experience, it helps operators greatly shorten the network construction cycle and save network construction costs. 

Goran Borntson pointed out that using 4.5G technologies such as Massive MIMO (multiple input multiple output) and Massive Carrier Aggregation (multicarrier aggregation), WTTx can greatly improve the spectrum efficiency and provide users with a broadband rate experience above 1Gbps. 

And through the high-gain CPE terminal (wireless home gateway), end users can enjoy the rich business and fun brought by mobile broadband, including video broadcasting, VoIP (network voice), enterprise private network, and even 4K IPTV and virtual reality movies, games, etc., at the same time, it can also help operators to effectively increase the average monthly user charges (ARPU). 

At the same time, WTTx also has the characteristics of rapid deployment. 

Traditional FTTx technology needs to dig trenches and poles, and optical fiber needs to be deployed to users' homes all the time. The more remote areas, the greater the cost and the longer the time consuming. 

While WTTx uses the deployed 4G base station, operators do not need door-to-door installation, users pick up the CPE terminal in the business hall, and they can enjoy high-speed broadband access service when they go home to power up, which greatly reduces the cost of operation and maintenance. 

In addition, WTTx and FTTx can complement each other. 

In remote rural areas, mountainous areas, forest areas and other places where FTTx is not suitable for deployment, WTTx can be used as the main home broadband access scheme; while in villages and towns with relatively developed economy and concentrated population, but have not yet deployed FTTx, they can give priority to using WTTx to test the water in the early stage of broadband service development to understand the local broadband demand, and when the number of users develops, it is the key investment area of FTTx, so as to improve the return on investment. 

On the other hand, in the areas that are close to the big cities and already have FTTx, operators can also provide differentiated products based on WTTx to create a complementary competitive advantage between fixed and mobile. 

Through the hybrid networking mode of WTTx+FTTx, it can help operators to obtain broadband users quickly, shorten ROI time, and greatly improve the return on investment. 

According to ITU statistics, 148 countries around the world have proposed national broadband strategies to improve household broadband penetration and provide a better Internet experience. 

Wireless broadband technology such as WTTx is also regarded by more and more operators as an indispensable part of the national broadband project, and it is an effective means to achieve the last kilometer of broadband access, rapidly bringing broadband to dense urban areas where it is difficult to deploy fixed broadband, and rapidly extending to rural and remote areas. 

Goran Berntson said that Huawei hopes to strengthen cooperation with industrial partners to bridge the digital divide, so that more families and people can enjoy the Internet connection experience; at the same time, Goran Berntson also hopes that there will be more spectrum to deploy WTTx in the Asia-Pacific region in the future, such as 700MHz (Band28), 1.9GHz, 2.3GHz (Band40), 2.6GHz (Band41) and 3.5GHz (Band42).
