SHENZHEN, China, April 24, 2020 /PRNewswire=KYODO JBN/ --

APT Satellite Company Limited (APT Satellite), founded in 1992 and listed in

Hong Kong Stock Exchange, is a leading satellite operator in the Asia Pacific

region, providing satellite coverage for more than 75% of the world's

population via high-performance in-orbit satellites. With advanced ground

equipment and network facilities, APT Satellite offers industry-leading

satellite communications and a wide range of value-added services to

broadcasters, telecommunications operators, and service providers across the

globe. These services include video broadcasting, Direct-to-Home TV, video

delivery, news collection, private corporate networks, distance education,

broadband access, mobile network base station transmission, and maritime and

aeronautical mobility applications, solidifying the company's position as one

of the most important satellite resources in the Asia Pacific region.

Audiovisual Upgrade Demands Drive Digital Transformation

Currently, video technologies are evolving from High Definition (HD) to

ultra-HD, leading to a host of new applications, such as 4K ultra-HD TV, live

video, HD social networking/e-commerce, and Augmented Reality/Virtual Reality

(AR/VR) gaming. The growth of the ultra-HD video sector requires the upgrade of

video production and storage devices, network transmission devices, and

playback terminals, accelerating the digital transformation of APT Satellite.

Satellite transmission delivers many unique advantages -- such as large

bandwidth, high speed, and wide coverage -- for new audiovisual applications.

In 2017, APT Satellite promoted 4K TV on its APSTAR-7 satellite to contracted

customers. Meanwhile, APT Satellite was exploring ways to make full use of the

advantages of satellite TV broadcasting in converged media content production

and broadcasting, efficient and collaborative transmission, and intelligent

terminal services, to achieve coordinated, integrated development. In addition,

unified network facilities serve as the basis for the service support and

application platforms, as well as production and office systems. Indeed, the

deployment of cutting-edge Information and Communications Technology (ICT) that

enhances the basic network, especially the office network, are instrumental to

improving service quality and efficiency.

For many years, the existing network of APT Satellite has consisted of mainly

Wi-Fi 4 (802.11n) devices. With limited performance and functionality, however,

these devices proved unfit for purpose in today's wireless office. Besides

lackluster wireless network speed, inadequate for handling a large number of HD

videos, there was also no mechanism for integrating wired and wireless security

policies. Additionally, Quality of Service (QoS) could not be guaranteed for

users in specific domains and the experience of different services couldn't be

assured in a hierarchical way. Facing all of this, APT Satellite sought a new

technology-led network upgrade solution that could address these challenges as

well as meet development requirements over the next three to five years. In

addition, given limited Information Technology (IT) expertise, APT Satellite

also wanted to simplify its network operations and increase automation.

Huawei AirEngine Wi-Fi 6 Takes Center Stage

After a series of solution competitions and Proof of Concept (PoC) tests,

Huawei's Wi-Fi 6 solution was selected for its ultra-high performance, stable

service experience, and intelligent Operations and Maintenance (O&M). A leader

in Wi-Fi 6 development over many years, Huawei is one of the 16 board members

of the Wi-Fi Alliance, has held three chair positions in 802.11ax working

groups, and contributed over 240 proposals since 2011, ranking first among all

device vendors. Indeed, uniquely powered by 5G technologies, Huawei's Wi-Fi 6

solution integrates advanced antennas, algorithms, and networking technologies

to deliver unparalleled performance.

After upgrading to Huawei Wi-Fi 6, APT Satellite's multi-screen office

experience has been dramatically improved. Employees can access the office

network, office system, and production system at anytime and from anywhere,

increasing overall work efficiency and mobility.

-Huawei's unique SmartRadio intelligent radio calibration technology

automatically detects air interface quality, intelligently optimizes the

network, and effectively improves network capacity and the user experience,

enhancing overall AP signal coverage stability. Moreover, signal strength at

the same location is increased by 100%, while coverage distance is increased by

20% compared to Wi-Fi 5.

-SmartRadio lossless roaming technology uses the network topology

identification algorithm to quickly find the optimal AP when roaming. Adopting

the soft handoff technique also ensures more stable mobile operations and

office work, achieving zero packet loss during roaming for mission-critical

services.

-SmartRadio Dynamic Turbo, an intelligent application acceleration technology,

helps achieve 10 ms ultra-low latency with multi-queue packet scheduling,

enabling the network to easily carry heavy-traffic services such as video

services.

A Secure, Reliable, and Easy-to-Maintain Network

In terms of security control, Huawei's next-generation Software-Defined Network

(SDN) controller -- the Agile Controller -- is used to associate the Wireless

Local Area Network (WLAN) Access Controller (AC) with the firewall, anti-virus,

and online behavior analysis systems, to flexibly manage user rights and

enterprise data resources. This allows wired and wireless security policies of

internal personnel to be unified, with unified authentication on the network.

Meanwhile, guests can access the Internet by registering through personalized

portals. Such a design allows authorized users to access secure networks, while

abnormal users are expelled, effectively preventing breaches in enterprise

networks and data security.

In terms of network O&M, Huawei has implemented major improvements with Wi-Fi

6. Big data analytics and machine learning algorithms have been adopted to

automatically learn network behaviors and identify fault patterns, helping

network management personnel proactively detect potential network issues.

Additionally, collecting network data from multiple dimensions enables the

network profile of each user to be displayed in real-time, and provides

visibility for the entire network experience, covering key metrics such as

users, online duration, connected APs, experience status, and more. Network

management is no longer device-centric. Instead, it focuses on the user

experience by accurately identifying problems that degrade it, providing

network optimization suggestions.

A Brand-New Audiovisual Experience

In the future, audiovisual services will become ultra-HD, virtual, fragmented,

and immersive, pushing the need to promote the ongoing transformation and

upgrade of broadcasting television services. Various new technologies --

including 4K/8K HD video, VR, big data, and Artificial Intelligence (AI) --

will be deployed throughout the entire ecosystem, from creation and production

to distribution, review, playback, monetization, and interaction, driving

innovation and precision production of audiovisual content. APT Satellite has

always been committed to making full use of its core strengths in broadcasting

television and online audio and video resources. By introducing and creating a

variety of high-quality content and transmitting the content through multiple

channels -- including satellite broadcasting, television, network, and mobile

terminals -- APT Satellite ensures an optimal viewing experience and meets the

diverse user audiovisual expectations and needs.
