Why does Huawei's smart home system choose plc instead of 5G?

5G cannot become the mainstream of smart home. There is a simple reason. One is coverage, the other is insecurity, and the third is relatively high cost.

1, the reason for overwriting is simple. At present, 4G coverage in many communities is incomplete, and some rooms have awkward signals. To solve the coverage problem, operators need to increase the number of base stations to solve the coverage problem. The mainstream of smart home is basically wireless. If the signal is not good, you can adjust and add wireless routers to solve it. If it is the operator's 5G, it needs to be solved by the operator, which is very troublesome.

2. The reason for insecurity is that 5G is the operator's network. If 5G is used as smart home, the home signal will be connected through the operator's network public network, and the security is insufficient. Pseudo base stations may invade the intranet. The traditional smart home is a family WIFI mode, which is encrypted by WIFI and then forwarded to the Internet through NAT, and the interior is basically safe.

3, the price is expensive. There are three levels of expensive here. The first is that 5G chips are expensive. The 5G chip costs 1,000 yuan, and the WIFI chip costs only a dozen dollars. If you choose 5G, it will be very embarrassing. I guess no one can afford it. Secondly, the traffic is expensive. Compared with home broadband traffic, 5G traffic is definitely much cheaper than home gigabit broadband. Finally, edge calculation is expensive. In order to realize the 5G Internet of Things, the 5G Internet of Things often needs the cooperation of 5G edge computing devices (you can imagine it as a server of an operator close to your home). The price of this kind of edge computing equipment is often in the millions, so ordinary families will definitely not use it, and the cost of operators can't be recovered. Therefore, operators often use this scenario in enterprises.

So what are the benefits of PLC? What PLC realizes is that there is a network when there is electricity, that is, when your home is renovated, the wiring determines where the smart home can be extended. This is a scene of the pre-installation market, that is, which hard-installed lamps and sockets can be directly connected to the network through PLC during home decoration, without purchasing additional intelligent furniture terminals such as WIFI, Bluetooth or Zigbee, and can be connected to the network by setting up the home network.

Of course, PLC also has problems, mainly because the chip is more expensive than WIFI (so Huawei's set is very expensive), and secondly, it is too professional and requires electricians to do a lot of things, and it is inevitable to use WIFI or Zigbee with PLC. I think PLC is just an aid.

For details, you can watch my album "Intelligent Deployment of the Whole House".

I know plc, 5G just knows it, but I can't use it! So let's talk about PLC!

1. Generally speaking, families can only do it at home, mainly intelligent light control and intelligent security. Just use the logo in PLC! Not counting labor costs, the equipment is counted in the price range of 1000 yuan by the point!

Labor and other expenses are not considered above! The specific cost will fluctuate.

If you consider face recognition, background music and so on, it is basically beyond my ability and needs other big names to supplement it!

You know what PLC is and what 5G is. You asked this question!

What is the fairy asking? PLC is the controller, is it in conflict with 5G? Whether you use 4G or 5G, you must have a controller, right?

Why do you choose 5G indoors? Install a 5G base station at home?

After reading a lot of comments, it seems that many people don't know that PLC is the abbreviation of programmable control and the abbreviation of power carrier communication.

It doesn't matter if you don't understand. Go down and find someone who understands. It is the worst thing for Baidu! This is the most basic principle of being a man and doing things! I really don't even want to scold you.

First, using the operator's 5g network is not something that a business can do. At present, domestic operators are really pushing some devices to interconnect through base stations. However, the base station resources and cost of operators are unavoidable thresholds.

Second, the network, no matter what technology and actual transmission, can't reach the speed of optical fiber, the low radiation of network cable and the stability of physical connection, so the physical connection is the best if it is fixed.

Third, Huawei's P technology actually replaces the previous weak current lines with power lines.

What is the purpose of asking questions?

The front section of PLC is 5G!
