With the transformation of traditional home appliance manufacturers across the Internet of Things smart home industry, to achieve intelligent home appliances networking, remote control, WiFi-2.4G wireless modules are valued and used in large quantities in many smart hardware. In fact, we are not unfamiliar with WiFi, as long as we surf the Internet, we basically can not do without WiFi, WiFi has taken over the whole world is no exaggeration. So, will WiFi-2.4G wireless module work in the smart home industry? What impact will it have on the smart home industry?

What is WiFi-2.4G wireless module used in the smart home industry?

WiFi-2.4G wireless module belongs to IoT transmission layer, built-in wireless network protocol IEEE802.11b.g.n protocol stack and TCP/IP protocol stack, which can convert serial port or TTL level to WiFi wireless network communication standard embedded module. WiFi-2.4G wireless module can be divided into general WiFi-2.4G wireless module, router Program WiFi-2.4G wireless module and embedded module three. Many traditional devices that can be networked are embedded modules with intelligent genes.

WiFi-2.4G wireless module in the field of smart home to enter the speed is quite fast. In the last two years, with the wave of the Internet of Things smart home industry, smart home riding the wind rise. Traditional electrical appliance manufacturers have been forced to transform to open intelligent situation pressure, WiFi-2.4G wireless module has become the key to open the road to intelligent traditional manufacturers. Traditional sockets, refrigerators, light bulbs, etc. can be implanted WiFi-2.4G wireless module to achieve a certain degree of intelligence.

Why traditional home appliance manufacturers prefer WiFi-2.4G wireless modules to open the road to intelligence

WiFi has a large inventory and a high degree of popularity. In life, WiFi is like an invisible net that fills our living space. Statistics show that by the end of 2014, a total of 9.98 billion WiFi devices were sold worldwide, and a total of about 4.5 billion WiFi devices are currently in use. At the same time, WiFi devices are expected to continue to grow at an annual rate of 10% in the next five years. In life, as long as you use smart terminal devices, I believe there is no one who does not know WiFi. It can be seen that this is the existing stock and popularity of WiFi, with the advantages of other wireless technology protocols can not be compared. WiFi-2.4G wireless module used in the field of smart home, the promotion is relatively easy, consumers are also easy to accept. Objectively, WiFi-2.4G wireless module provides advantages for smart devices, and it is easy to ride on this fast train.

WiFi-2.4G wireless module is cheap. WiFi-2.4G wireless module is an electronic component, but it is very cheap, and can even be said to be “cabbage”. In January this year, Xiaomi launched a WiFi universal module for home appliances, one only costs 22 yuan. After that, the 360 company launched a lower price, WiFi-2.4G wireless module for one yuan, already below the cost price. Such a low price, traditional equipment embedded WiFi-2.4G wireless module in a second transformed into a smart home, to achieve device networking and remote control. The road to intelligence is actually so simple.

WiFi-2.4G wireless module R&D threshold is low. Unlike ZigBee modules, WiFi-2.4G wireless modules have a very low threshold for research and development. A qualified graduate of the relevant profession can complete the relevant design in a very short time. For ZigBee modules, the source code alone is 400,000 lines, which takes 2 years to read through. Therefore, from the perspective of manufacturers’ research and development, smart devices embedded with WiFi-2.4G wireless modules can complete the research and design work in a short period of time and put into the market, with fast results. From the above 3 articles alone, it can be seen that WiFi has obvious advantages in some aspects, and should be used in the field of smart home is logical and very “suitable”.

WiFi-2.4G wireless module has very obvious advantages, why can not occupy the mainstream in the field of smart home
WiFi-2.4G wireless modules have a large inventory, but security has been questioned. The security issue seems to have become the label and headache of WiFi-2.4G wireless module, whenever it is mentioned WiFi-2.4G wireless module always can not get around this topic. WiFi password cracked, WiFi devices under attack, these words often appear in the news headlines so that we have become accustomed to. In the field of smart home pay more attention to smart home security issues, because smart devices and life, user property is closely related, more about the safety of user privacy data. Once attacked and cracked, the damage caused is much more serious than WiFi password leakage and will be irreparable. Meanwhile, WiFi-2.4G wireless module supports OTA, remote update and solid-state update, and smart home based on such module may be exploited by module providers.

WiFi-2.4G wireless modules with health hazards. It is not alarming that wireless technology has a certain amount of radiation, and WiFi is more of a health threat compared to other wireless technologies. Recently the news reported a case of a British 15-year-old girl who committed suicide because of WiFi signal interference, the British girl felt unwell due to WiFi signal, fatigue, headache and bladder disorder problems and finally committed suicide. This case itself makes us feel sorry for her, but it also supports the harm that WiFi signals can cause to the body. It may not be easy to notice in life, but if you live in a home armed with WiFi-2.4G wireless module smart devices for a long time, it will be harmful to your family’s health, especially for children and pregnant women, and the loss to your family’s health is irreparable.

WiFi-2.4G wireless module smart devices lack the ability to interconnect and sense learning. It would be a big mistake to simply understand the device networking and remote control as a smart home. Smart home is not only able to remote control, but more importantly, multiple smart devices interconnect and work together, bringing convenience and safety to life. For example, a gas leak while linking the robotic valve and ventilation system is handled in time and notified to the user’s cell phone. However, WiFi-2.4G wireless module smart devices do not have the perception learning ability of interconnection, and the smart home that only relies on device networking and remote control seems to be very chicken-hearted and not practical.

In summary, WiFi-2.4G wireless modules do have advantages that other wireless technology protocols do not have. However, if we cannot further improve several core issues in the field of smart home, such as security, health and interconnection, the smart home with WiFi-2.4G wireless module can only be a castle in the air.
