5G network construction requires continuous innovation
Just like the evolution process of mobile phones from feature phones to smart phones, as the functions of mobile phones are getting more and more powerful, but the battery technology has not been a breakthrough revolution, various smart phone manufacturers have turned their attention to the innovation of charging technology. . Because no matter how powerful the function and how advanced the hardware is, a smart phone without the support of electrical energy is just a "brick", and the same is true for 5G base stations.
As we all know, 5G has three major atomic capabilities, namely eMBB: enhancement MobileBroadband, enhanced mobile broadband; uRLLC: ultraReliable & Low Latency Communication, ultra-high reliability and ultra-low latency communication; mMTC: Massive Machine Type Communication, massive machine type communication to cope with Three application scenarios build a fully connected world where everything is connected. But 5G is so good, it also follows a law of unity of opposites, "no one is perfect", 5G also has a headache shortcomings.
First, the problem of expensive cost. It is well-known that operators have huge pressure on the cost of building 5G networks. Simple calculations. According to the previous collection of China Mobile, the price of a single-seat 5G base station was about 160,000 yuan. According to calculations, 5G needs about 10 million base stations to achieve the same coverage effect as 4G, so the total purchase investment of 5G base stations will reach 1.6 trillion, which is an astronomical figure.
However, this is only the cost of telecommunications operators to purchase equipment, and does not include electricity, maintenance, labor, and site fees after the network is built. Therefore, reducing the cost of network deployment through a variety of innovative methods has become a task for major operators to sharpen their heads. For example, in the power supply and service transmission of base stations, the traditional solution is for operators to introduce external city power through composite optical cables. The base station optical cable collection projects announced every year are usually tens of millions of core kilometers. How can this money be effectively saved?
Secondly, the problem of network deployment efficiency. Regardless of the cost of fiber optic cable procurement and human maintenance, in the process of base station construction, the progress of base station opening is often affected due to the introduction of external electricity or the long transformation period. For example, it is well known that one of the biggest selling points of 5G is its flexible deployment capabilities.It can connect to any IoT device anytime and anywhere through large bandwidth, low latency, and massive links. However, 5G base stations themselves are difficult to achieve flexible deployment anytime and anywhere, because Mobile communication base stations are not only base station equipment, but complete structural components including computer rooms, wires, tower masts, etc., of which power supply equipment is very important, and how to save money in scenarios such as disaster relief, large-scale evening parties, and sports events What about the "last cable"? Therefore, exploring the speed and flexibility of network deployment in different environments is also an important issue that operators need to solve urgently.
