Why turn off the base station?
Since entering the 5G era, the envisioned beautiful scenes have not yet appeared, but an unexpected dilemma broke out first-operators are overwhelmed by the electricity bills of expensive 5G base stations.
Recently, China Unicom combined the distribution of 5G users and terminal usage, respectively, for 3 different base station radio unit devices (AAU) that have been connected to the network, and periodically turn on the deep sleep function in the no-load state at different time periods to realize the energy consumption of intelligent base station equipment. The purpose of control. Simply put, it is to turn off the 5G base station every day (21:00-9:00 the next day) to reduce energy consumption and save electricity bills. Some people may wonder, with the three major domestic operators earning 500 to 600 million a day, why do they care so much about electricity bills?
In fact, the life of operators in recent years has not been very good. Revenue and profits have fallen into stagnation or even decay. Since the source of income is not enough, they can only think of ways to reduce expenditure. At present, with 5G this" In the comprehensive commercial use of energy-intensive consumers, electricity bills have become one of the operators' biggest operating costs. Without exception, the three major operators are actively trying to reduce electricity bills in various ways.
According to data from China Unicom's field trial in Luoyang, after the AAU deep sleep function is turned on at all times under no-load conditions, a single A9611 model AAU will save about 6.09 yuan in electricity per day, and a single A96331A model will save about 5.61 yuan in electricity per day. , A single A9622A model AAU will save 3.11 yuan in electricity bills per day.
A 5G base station is generally configured with 3 AUUs, so on average, each base station can save 15 yuan per day. At present, more than 200,000 base stations can save 3 million yuan per day, which can save nearly 1.2 billion yuan a year! This is still the current state. If we calculate the construction volume of 1 million 5G base stations by the end of the year, we can save 6 billion yuan! Think of Unicom's net profit in just over 10 billion a year.
Therefore, it is a last resort for operators to shut down 5G base stations regularly to save electricity bills!
What are the problems?
We do not use 5G, this has no effect on us, but in fact, network problems may already affect your existing business!
Several possible factors affecting the signal:
1. Base station coverage issues.
Operators all have blind spots in network coverage. Some have no signal, and some cannot guarantee stable communication. This is especially obvious with the new network standard NB-IOT.
2. External factors of the
base station Base station maintenance, base station upgrades, new high-rise buildings around the base station, and interference from various external factors may cause signal instability.
3. The problem of base station capacity The capacity of
each base station is limited. A 4G LTE base station has a maximum capacity of 1200 users while meeting a 20Mbps bandwidth. If the limit is exceeded, the user experience will be greatly affected, and the network speed may be slow or even unable to use the network. With the increase in Internet of Things devices, people may feel this way in densely populated places such as train stations and schools. It is very difficult to scan WeChat.
IoT devices can greatly reduce labor costs and operational efficiency, but when IoT devices have problems, the ability of equipment maintenance personnel is more demanding. If the failure rate of IoT devices is high, it will increase labor and operating costs. Therefore, How to ensure the stable operation of equipment is of utmost importance!
Sometimes, the
violent storms can cause the antenna to
be distorted, which will also affect the signal quality. The
base station signals are transmitted through radio waves. They are fragile and sensitive, susceptible to interference, and attenuate very quickly during propagation. How to avoid imperfect network coverage and emergencies The impact on the network is two difficult problems that IoT devices need to overcome.

01 Insufficient network coverage of a single operator.
All Netcom cards can select the preferred network according to parameters such as signal strength/PS domain/signal-to-noise ratio, and achieve optimal network selection (supports three major operators)
02 Unstable access caused by network changes
Internal problems such as base station shutdown and base station upgrades, or external problems caused by changes in the surrounding environment, will affect the network. For all Netcom cards, you can re-select the network according to the network connection status
Case 1: NB-IOT room temperature acquisition
Customer NB room temperature acquisition, the signal in the urban area is OK, there is no signal in many places outside the urban area, or the signal is not good, you need to test the signal with an instrument before each installation, and then install it. Netcom card solution, mobile and telecommunications choose the best network access, reducing the training cost of installers.
Case 2: CAT1 security gateway
products are mainly used in shopping malls, stations and other places with heavy traffic. When the equipment offline rate is the highest, it exceeds 5%. When the equipment is offline, it cannot guarantee the security warning. At the same time, the poor signal also greatly reduces the battery usage time. , All Netcom cards, through the network abnormality judgment, re-select the network.
