In office buildings, hospitals, railway stations, large supermarkets such places, cell phone signal is simply a disaster, 5G improvements can be made to the right?
Speaking 5G, the industry there is a popular saying: 4G change lives, 5G change society. In June, issuing commercial licenses 5G declared the country officially entered the first year of commercial 5G. Whether it is foreseeable chips, network, or terminal areas, are fast parallel development. As a provider of network services, 5G self-evident the importance of operators. For us ordinary users, our impression is limited to 3G faster than the 2G, 3G and 4G speeds faster than, the 5G comes certainly bring more changes.
As for the phone signal in a complex environment, the signal is weak Why? First, we must be clear communication, mainly rely on electromagnetic wave propagation, and the electromagnetic wave frequency resources are limited, different frequency, speed is different, characterized by greater frequency, the greater the bandwidth, so the greater the speed. Our current network in the lower frequency bands, the advantage of better performance, you can achieve good coverage, but the problem is very precious resource, and 5G utilizes the high frequency band, just to use up idle resources. With the development of 2G to 5G, with increasing frequency, speed faster and faster.
In fact, in-depth industry know, 3G, 4G just bandwidth extension, but 5G is turned into a linker connecting people from the operators of the agreement has been a fundamental change, so now mature product solutions supporting it? You can maximize the potential of 5G do? In the recently held Asia's technology industry event "MWC19 Shanghai", many domestic manufacturers released on 5G products and solutions, if you understand the principle of them, you probably will be able to understand why 5G can bring revolutionary reforms.
Rui McNair to-end solution, for example, contains three major aspects. First, the terminal side, Rui McNair 5G CPE products to meet the problem of the lack of early 5G terminal. Second, the network side into contact chamber Ruijie points 5G digital solutions, coverage and capacity to meet the problem of complex indoor environment. Third, local core network equipment, mainly used in vertical industries to meet the privacy requirements of vertical industries such as industrial, medical, education and so on.
5G chamber on the access network side the digital partial solutions, but also during this exhibition MWC Shanghai, one display content ruijie focus, the master station skin (the BBU), the extension unit (Phub), the remote unit (PRRU ) consists of three parts. The white-box software program via the stack of protocol architecture, a container support edge computing technology and networking mode SA independent, easy to implement and expand the real roaming ⽆ characteristics.
5G ruijie new interior architecture, since the white box using Flex-RAN architecture, by the BBU under pRRU flexible expansion and merging packets between 1-4 hour for any region. For example, the lower hanging pRRU 64 every 32 divided into two groups as a cell, cell division and cell support combined, the BBU support cell 2 and cell 4, a consistent interface, seamless expansion, comes in handy for operations business or enterprise division stepping ⾏ 5G investment.
▲ elastic expansion, investment step by step
Next, the program may be scheduled at low delay multiple access terminal controlled and balanced, and pRRU Phub by merging and forwarding the digital signal, the digital controlled chamber partition scheme roaming region, may be implemented within the movement area of 500 square meters to 30,000 no roaming, zero packet loss and low latency to meet the needs of industrial mobile scene.
▲ 3 million square meters of free roaming coverage
Ruijie room 5G single stream DAS traffic density sub-programs contrast the current office environment, commercial buildings, hotels, dormitories, etc. used in the scene has increased dramatically, by 4 cell pattern 5G digital room sub-programs, the performance increase to more than 20 times, DOU fully meet the growth in these scenarios over the next five years.
Therefore, we can believe that, 5G arrival, our net environment will enhance the quality occurs.
