[५ जी इन्फ्रास्ट्रक्चर]Overview of Hong Kong's 5G development, creating a network-ezone.hk-technology focus-5G mobile statically

Many regions of the world, such as South Korea, Canada and China, have entered the 5G network era in early 2019, and high-speed connection technologies continue to develop. Although it appears to be backward, the network infrastructure is constantly hitting the ground.

  • Hong Kong 5G Development
  • China Mobile Hong Kong (CMHK), Hong Kong Telecom (HKT) and Smarton (Smartone) provide DGG services
  • Different frequency bands have their own characteristics

Upgrade 4G base station

The Hong Kong government announced in late March 2019 that 26GHz and 28GHz spectrum would be administratively assigned, a total of 1200MHz spectrum, and 5G Mobile would be provided by the three local telecommunications providers of China Mobile Hong Kong (CMKK). Hong Kong Telecom (HKT) and Smartton (Smartton) Services; Smartton finally decided to focus on developing the first 3.5GHz spectrum. The other two companies are actively testing 5G in Hong Kong and will complete assembly of 5G base stations. End of 2019

Currently, the Hong Kong government is actively developing smart cities. Internet of things, Internet of vehicles and other technologies are common trends. 5G is a major element of mobile network development. Unfortunately, due to two major satellite stations in the east. Tai Po and South Stanley on Hong Kong Island, they are called “5G Restricted Areas”. The satellite station at Tai Po is massive and covers a wide area, including Sha Tin, Ma Aan Shan and even parts of Fanling. It is estimated that close to 1 million users will be affected. The satellite station at Stanley is close to the waterfront and the effect is relatively small. If the problem of the 5G restricted zone is not resolved, the users of the area will not benefit, and if the user is already using the 5G network, after the user enters the “restricted zone”, the signal 4G. And will change in connection. The speed will drop immediately, harmful to consumers. Experience.

Bandwidth is large and wide

Hong Kong’s 4G (even 2G and 3G) uses a spectrum between 8502 Hz and 2,600 MHz, with a total bandwidth of 552 Hz. In the 5G era, the total bandwidth has reached 4,500MHz, which is 8 times more than the previous mobile services. It can be seen that the 5G “water pipe” is wider and larger, and the speed is inherently faster.

With the advent of 5G, Hong Kong telecom companies HKT, CMHK, 3HK and Smartone have progressively introduced 5G network services. Among them, CMHK is the most “5G Golden Band” Hong Kong mobile network operator. According to the CMHK’s official announcement, the current urban outdoor coverage rate has reached 90%, and is intended to expand more services using its own advantages that can achieve different aspects of life through the 5G network Can.

Characteristics of different frequency bands

Behind the vast amount of total bandwidth are 3.5GHz, 4.9GHz and 3.3GHz, and 26 / 28GHz, respectively, known as the “high frequency band”. Hong Kong’s 5G network services mainly use the middle and low-frequency bands. Although the transmission distance is long, it has a large range of coverage. Therefore, the 5G network used on the road depends on 3.5GHz (3.3GHz is used to complement. Indoor use). It is called the “Golden Band”.

For 26 / 28GHz due to the high frequency (millimeter wave mmWave), the transmission distance is very short, so it is mostly used in convention centers to provide extremely high-speed connections to those in need; And mainly 4.9GHz is used. To complement Hong Kong’s “5G” Prohibited Areas “, otherwise users of those regions will not be able to use 5G.
