The router is "outdated", and the future is the era of home base stations?

In the 2G era, the base station coverage radius was as high as 5-10 kilometers. In the 3G era, this number was reduced to 2-5 kilometers. In the 4G era, the base station coverage radius was only 1-3 kilometers. Today, in the era of 5G networks, base stations with a coverage radius of only 100 to 300 meters have brought too much trouble to operators. The frequency band that is easy to popularize has been applied in the early stage of communication technology development. Later communication technology can only make concessions and use frequency bands with small coverage and weak penetration ability. However, in this way, it is very painful for operators. It is necessary to build more base stations to achieve coverage of the same size area. Not to mention the rising cost, because the penetration ability is too weak, the user experience may be worse.

As a result, the home base station is here. After the arrival of the 5G era, the penetration ability and coverage of the signal will be weaker, and the home base station seems to usher in the dawn. On August 24, at the 6th Future Network Development Conference, China Mobile Research Institute and China Mobile Zijin (Jiangsu) Innovation Research Institute officially released the world's first 2.6GHz 5G integrated femtocell. China Mobile said that the use of the integrated femtocell is to provide a more stable 5G connection for scenarios such as homes, conference rooms, and small shops.

Home base station, making the signal no longer a problem

There are four types of base stations, namely macro base station, micro base station, pico base station , Femto base station, the latter three are collectively referred to as "small base station", that is, the main members of the home base station. The coverage of the home base station is much smaller than that of the macro base station. Correspondingly, the power consumption of the home base station is also very low, generally not exceeding 20W, which is about one-tenth of the power of the refrigerator. The home base station needs to access the broadband through the network cable to connect with the communication operator, but we can rest assured that when the home base station is connected to the mobile phone, it will not occupy the speed and bandwidth of the broadband. As for the experience, the netizens of the communication people's home said that it may be because there are fewer people connected to the Internet. The network speed is faster than that of connecting to a macro base station, but the delay is slightly higher than that of connecting to a macro base station. Fortunately, it is only a little higher, and there is almost no difference in playing games. . Looking at the connection principle, some people may think that this is an oversized router. In fact, the home base station is very similar to the router. What we can do with a router, the home base station can do it, and in the absence of a signal, we can't make calls, but the home base station can provide a stable signal connection, which is the biggest advantage of the home base station.

There are many femtocells on second-hand platforms such as Xianyu, but they are basically 4G networks. There are not many home base stations for commercial use, and you need to apply to the operator to buy them. It should be noted that the home base station can not be used after buying it, but also needs to apply for permission from the operator. There are many people who are engaged in the work of operators on the website of Communication People's Home. They said that generally only places with particularly poor signals can apply for femtocells, and they may need to call the operator several times to apply, or go to the Ministry of Industry and Information Technology to complain to the operator . Photo source: The home base station of the communication person obviously has so many benefits, and it is something that appeared in the 3G era. Why do we hardly touch it in our daily life? The reason is actually very simple. The home base station is not a necessity, but has a strong competitor.

Routers, the biggest enemy of femtocells

have been discussing with netizens for a long time, and the reasons why netizens oppose femtocells are consistent with what Xiaolei thinks , buy equipment by yourself, use your own broadband, electricity, traffic, but have to provide the network for others (registered users have priority), and I am naturally unhappy. More importantly, the network difference also depends on how bad it is and whether it is still within the tolerance range, because as long as we can make and receive calls, we can accept it. As for the networking function, we have another choice - a router. No matter how fast the network speed of the home base station is and how low the latency is, if we connect it to the Internet, we will consume package data. The traffic of the 5G package is limited, but the traffic of the broadband package is unlimited. The traffic can be used in scenarios without WiFi, but the WiFi is fixed in one's own home. The embarrassment of home base stations is here. Compared with 5G and WiFi, even if the WiFi network speed is slower and the delay is higher, as long as it does not affect normal use, I believe most people will choose WiFi, because the traffic can cope with no WiFi available. .

You can insert a mobile phone card and convert 5G network into WiFi or wired network. The problem is that we obviously have more stable broadband routers to use, so why use CPE? The same is true for portable WiFi, and because of its small size, many products still use IoT cards, and the signal strength may not be as good as that of mobile phones. If it is to connect devices such as laptops and tablets, how much does it cost to open a hotspot on a mobile phone? When Xiaolei read an article published in 2008, he found that the author believes that the femtocell will be the biggest opponent of the router in the future, but today there are not many people who have access to the femtocell. In addition to the development of the broadband industry, another important reason is that The development of instant messaging industry. From QQ and MSN back then to today's WeChat, instant messaging has become more and more convenient and has become the main way for us to communicate with others. The people who usually call us the most may only be the takeaway riders. Because of this, the role and importance of the base station has been weakened again. Photo source: Lei Technology Production There is no doubt that the existence of routers has brought a lot of trouble to the home base station, but the situation seems to change in the 5G era. The coverage of 5G networks is smaller and the penetration ability is weaker. In large office buildings, urban villages, subway stations and other scenes, places with poor signal often appear. In addition, although there is a lot of knowledge about base station radiation, there are still many people in China who oppose the construction of base stations, resulting in extremely poor signal in some cells, and even unable to answer the phone to get takeout. In these areas, home base stations are required to fill the vacancies of macro base stations and provide signal bases for users. However, if home base stations are to be popularized, operators need to change their strategies.

The future of femtocells is in the hands of operators

When operators study femtocells, they must be interested in the commercial use of femtocells Value, but to make home base stations popular, operators must consider the cost of installing it for ordinary people. The home base station is not particularly expensive. The price range given by Xianyu is 120 yuan to 2400 yuan, but Xiaolei took a look and the price of 4G home base station is mainly concentrated around 300 yuan. It is predicted that the price of 5G home base stations will be between 1,500 yuan and 3,000 yuan, which is nothing compared to the signal experience it brings, but most people may look at home base stations with a "not" very needed attitude. Source: Xianyu screenshot Therefore, the rental system + free use may be the optimal solution for femtocells. The rental system can make users feel more at ease using their home base stations, and they can return them when they don’t want to use them. If they use them for a long time, they are not much different from buying them. On the operator's side, although the product may have to be refunded, the rent received at the initial stage can be used to carry out other services. In addition, although the power consumption of 5G small base stations is not high, there are many more that can be built, and there are macro base stations. The electricity bill is not a small amount. After the popularity of home base stations, operators can be lazy and build less base stations and save some electricity costs, which is a win-win situation. Cover image source: pixabay
