The 5g revolution promises amazing data rates of gigabits per second and near instantaneous connectivity. It is expected to have a huge impact on many industries and change the lives of billions of consumers and suppliers around the world. Like every new generation of wireless technology, 5g will greatly improve the speed and quantity of coaxial cable data transmission, but this will have more profound consequences than ever before.
5g is not just a mobile phone. It will become an important foundation for the development of Internet of things (IOT) and virtual reality (VR) applications in all walks of life. The new generation telecom network must support a large amount of data traffic and ensure ultra-low communication delay to achieve a smooth user experience.
Although the high frequency spectrum for 5g provides significant new capacity and data speed, it also means shorter propagation distance. In high traffic areas such as cities, town centers and business districts, operators will need a large number of smaller cells with low-power base stations, which will provide the required coverage and capacity. In addition, in order to achieve a high user data rate, a multiple input multiple output (MIMO) system with dozens of antennas is required to enhance the signal when needed.
To understand the challenges associated with 5g implementation, a typical 4G macro cell will cover an area of about 25 square kilometers. In contrast, 5g may require 20 or more units to cover one square kilometer. In addition, statistics show that 80% of mobile traffic occurs indoors. Considering the diversified nature of 5g services, this figure is expected to increase to 85%. Therefore, indoor network quality will become the competitive advantage of 5g mobile operators in the future.
As a result, even if 5g is a wireless technology, its deployment will involve more optical and copper connection devices, whether in the wireless access domain or back to the routing and core network infrastructure. In addition, 5g will require more antennas than 4G. That’s why the world’s continued demand for faster, more efficient connections requires state-of-the-art wired infrastructure to make 5g possible and break these barriers. When telecom operators need to connect microwave antennas to indoor units, they have one of three kinds of cables to choose from: coaxial cable, optical fiber cable or twisted pair high-frequency cable, all of which bring benefits and disadvantages.
With the introduction of 5g test, twisted high-frequency cables are becoming more and more popular. The advantage of using twisted high-frequency cables to connect microwave antennas to indoor units is that you can combine data and power in one cable. This means significant cost and material savings for operators – you can effectively reduce costs by half by installing only one cable, while for other cable types, separate power and data cables are required. Using fiber optic cables to connect an increased number of 5g antennas can be very expensive. Therefore, high frequency cables have become more and more popular in the past few years, which we predict will only increase because they are not only cost-effective, but also easier to install than other cable types.
On the other hand, fiber optic cables are more sensitive to conditions such as humidity and dust. In most cases, fiber optic cables are pre terminated, which means that the installer must plug in at both ends. However, fiber optic cables carry only data. Power must be supplied through a separate cable, which must usually be cut to length, stripped and terminated.
However, twisted high-frequency cables are not the answer to every installation. Their performance tends to decline over a long distance. This means that if the antenna is too far away from the indoor unit or the antenna needs to be placed closer, which may be inconvenient, the operator will be forced to use other types of cables. In order to help mobile operators meet the many challenges of 5g, Nexans and other companies have developed a 5g ultra dense infrastructure network, including innovative optical fiber cables and components and a new high-frequency twisted pair designed to meet the needs of new microwave networks.
5g will undoubtedly represent a major development of modern network communication, but in addition to evolution, 5g also has potential revolution. Its possibilities are almost endless, but smarter and more intensive infrastructure is the key to achieving the vision. It is just around the corner. It is expected that China and Europe will have a preliminary impact by 2020. 5g’s early demand for wired cable technology will far exceed the demand for cable technology to ensure the realization of the dream of near instantaneous high-speed connection.
5g, as the key to the fourth industrial revolution in the future, is also the core of tiankele as a science and technology enterprise. To improve the product quality and performance of 5g coaxial cable is the goal that tiankele people have always adhered to in the field of RF and microwave.
