If it is divided from the form of network connection, today’s smart home is mainly divided into two camps: wired and wireless. If you want to pursue stability, wired is undoubtedly the best choice, so it is widely used in villas, large flats and other fields, while wireless smart homes are highly dependent on the network, and most of them can only be used in small apartments. But even so, more and more manufacturers in the market are beginning to get involved in wireless smart homes.

The Pros and Cons of Wired and Wireless Smart Homes

In the past, the network wiring method of smart home was basically wired network, and it was necessary to make corresponding layout of the house in advance, whether it was a separate bus 485, or like Huawei’s PLCPower carrier, or CEBus bus, APBus bus, CANBuses, etc., need to be wired in advance before the house is renovated. Of course, the power carrier is relatively better.

The representative manufacturers of wired technology include Hedong, Crestron, ThinkHome, Control4Wait. The biggest advantage of wired technology is that the technology is very mature, the system is stable, and the control reliability is high. After all, the smart home is mainly based on wired solutions at the beginning, and wired intelligence usually relies on 4-core signal lines or network cables for data transmission, so there is basically no data packet loss, and the anti-interference ability is very strong.

Another significant advantage lies in the long-term use, most civil residential decoration service cycle is usually 1520Years, so for smart homes, especially large smart homes, it is best to use 15Year requirements can be easily achieved using a wired solution.

However, the disadvantage is that it is expensive. Usually, the price of a whole cable in the market ranges from tens of thousands to hundreds of thousands of yuan, which is almost difficult for ordinary families to afford. This is why this solution is usually used in villas, large flats or large buildings. In addition, for users, if they want to add or replace new products, they need to consider the position of the switch panel and wiring.

Not only is there trouble for users, but for manufacturers, after-sales maintenance of wired smart homes is more troublesome and requires door-to-door service, and wired smart home solutions are basically only applicable to unrenovated households, which belong to the pre-installation market, and the sales time is relatively short, which is not conducive to The promotion of new products is difficult to achieve follow-up sales.

Relatively speaking, the advantages and disadvantages of wireless solutions are almost the opposite of wired ones. At present, the main wireless technologies are mainly radio frequency RF, ZigBee, Wi-Fi, Bluetooth, etc., the advantages are that the technology is relatively mature, easy to learn, and has a two-way feedback mechanism, and the laying of the network is relatively simple.

In short, the advantage of wireless is flexibility, and products can be added or moved at any time to meet the needs of ordinary consumers. And it applies to both unrenovated households and renovated households.

However, the disadvantage is that it is easy to connect to the Internet. In such a complex network environment, it is not very stable to use a wireless network to control a smart home. For example, it may lead to the situation that the wireless smart light cannot be turned off or is delayed to turn off when it is being controlled. When a function is disturbed by a delay, it means that the experience for consumers plummets.

Interestingly, even though the wireless smart home solution has various disadvantages, many terminal manufacturers have gradually increased the proportion of wireless smart home, such as Huawei, Haier Zhijia, Lumi, Ou Ruibo and so on.

Wireless is going mainstream

According to public market data, from 2016 to 2020, the size of my country’s smart home market has increased from 260.85 billion yuan to 514.47 billion yuan, with an average annual compound growth rate of 18.51%. Expected 2022In 2018, the size of China’s smart home market will exceed 6500billion.

The rapid growth of the smart home market scale, with 5GIt is closely related to the advancement of technologies such as IoT, IoT, etc. These technologies accelerate the development of the Internet of Things and make it possible for the smart home to realize the interconnection of everything.

At the same time, the emergence of the Matter protocol also makes it possible for various smart home manufacturers to break the ecosystem and achieve real interconnection. For consumers, this means that the experience of using smart homes will achieve a leap. Even ZigBee or Matter can conduct ad hoc networking, allowing users to control smart home products even when the network is disconnected.

For manufacturers, the more realistic meaning is that the cost of wireless smart home is low and the layout is flexible. This also means that the penetration rate of domestic smart homes can be increased faster, thereby activating the entire market.

And the penetration rate of smart home in China has been at a low level,2018Annual statistics, the penetration rate is only 4.9%, even if it reaches 2022year, the penetration rate did not exceed 10%. There are of course many reasons, but only from the perspective of wired and wireless, wired smart home solutions need to be arranged when users decorate their houses, but looking at today’s real estate market, this road is not easy, and many young people Didn’t buy a house either.

Therefore, choosing a wireless smart home can deliver products to the market faster, accelerate the penetration rate of smart homes, cultivate market users, and pave the way for subsequent products. And the product iteration speed of smart home is fast, about 3-5It has been updated in about a year, and the relatively cheap price makes it easier for users to accept shorter product updates.

Today, smart home products have begun to develop from smart single products to whole-house intelligence, but smart home devices have also begun to develop from fixed to mobile. Research Institute IDCIt is believed that the advancement of indoor positioning technology and the penetration of intelligent mechanization into the consumer market will further promote the development and innovation of home mobile devices. The agency predicts that 2022In 2018, 3% of smart home devices will have autonomous mobility.

At the same time, the development of new technologies is also driving the penetration of wireless smart homes, such as Canadian startup SPARKA high-bandwidth wireless protocol with ultra-low power consumption and ultra-low latency has been developed. This protocol effectively extends the battery life of electronic products. At the same time, when used together with energy harvesting technology in smart homes, it can realize wireless devices such as sensors. Running without batteries, this technology can effectively solve the power consumption problem of wireless smart home.


The wired smart home solution is stable, but the barrier to entry is too high. For many consumers, it is very unlikely to directly transform a full set of wired smart home solutions without experiencing smart home. And wireless smart home products can more conveniently allow consumers to experience the convenience brought by the product, and also allow manufacturers to achieve faster product iteration. The development of technology can also promote the progress of wireless smart home.
