Dual-band WiFi module refers to the WiFi module that supports both 2.4GHZ and 5GHz bands. The dual-band WiFi module can operate in the 5Ghz band, which is much cleaner and can easily avoid interfering with each other. The advantage of 2.4G is that it has good ability to penetrate the wall, and the disadvantage is that it is easy to be disturbed. The advantages of 5G are strong anti-interference ability, wide band width, high throughput rate, and strong scalability, but the disadvantage is that 5G is only suitable for indoor small-range coverage and outdoor bridge, and the attenuation effect of various obstacles on it is much larger than 2.4g.

introduction
Frequent customers ask: "What products are sold now, can the popular products continue?" Instant Huayi lighting is planned with the crystal lamp series as the core product group, then the author can not tell them that the crystal lamp is good to sell, sometimes I really want to say this, the heart is also out of the business needs of the development of customers, in fact, the author does not know how to answer. At the same time, quite a part of the bosses of business owners are also very confused. Which products are now profitable? I don't even dare to make an axe. However, the background of the origin of the university's physics major tells that "the existence is reasonable", the existence of any one thing has its inevitable law, just as Marx abstracts the complicated social development into the law of social development, as the trend is very obvious. The lantern product, the hand of God is also guiding our business investment. Under such pressure, the author has been stagnation and unresolved. When talking with the national managerial hotel in the night, the time and brand growth of the well-known brands in the lighting and lighting industry basically constitute a perfect curve. The author slammed the knot, poetry and passionately drawn the perfect curve "the fourth wave of the lighting industry", intoxicated by such a simple curve, thanks to the gift of nature, the most precious essence of the world is expressed by a perfect curve.
Interpretation of "the fourth wave of lighting"
The author has been engaged in the lighting and lighting industry for 8 years. He has gone through 6 positions from business representatives to marketing directors. It involves three basic business aspects of distribution, engineering and retail of lighting and lighting. He has done detailed planning and planning, planning and training. Basically, it grows with the branding process of the industry. However, the author has always used the "third eye" to see the world's thinking habits, and analyzes the subtle changes in the industry with a research attitude. Any change in the lighting industry involves sociology, economics, political science and other sciences, according to personal analysis. The author has the following points (see the graph).
First, from the development of the lighting industry, basically in accordance with a popular cycle of 6 years, the first peak in each product cycle will be the owner of the first brand, climbing to the peak represents the altar of the gods. In the first cycle, many investors will flock to enter this field. In fact, according to the Chinese business ancestor, the words "low rallies", this time the risk is the biggest time. In 2003, the author encountered the peak period of the home improvement industry and lost the business. From the perspective of investment science, risks and opportunities coexist at this stage, but doing industry is a long-term investment behavior. If speculation follows the trend, the risk is too big. The strategic concept is the truth. It is precisely because there are more followers, so the winners are rare. The author once listened to Wen Shu, the spiritual leader of Huayi Lighting Group, sharing the investment philosophy. The success of Huayi is inseparable from his keen investment perspective.

Dual-band WiFi module has a stronger and more stable Wifi wireless signal, higher transmission speed, and can make wireless devices more power-saving, to meet the future high-definition and big data wireless transmission needs.
When selecting a dual-frequency WiFi module, we should pay attention to these parameters of the WiFi module: size, package, frequency range, data rate, transmission rate, transmission distance, communication interface, power supply voltage, antenna interface, etc.
Dual frequency WiFi module can well meet the functional needs of users, increase the competitiveness of the product, while the WiFi module is easy to use, can shorten the user product development cycle, speed up the product market! Users can make choices according to actual needs!
Choosing a dual-band WiFi module may need to pay attention to the following points:
(1) Consider the transmission power of the dual-frequency WiFi module
The transmitting power of the WIFI module is generally about 18dBm, and the transmitting power of the high-power WIFI module is about 28dBm.
(2) Transmission rate
Consider whether the dual-band WiFi module supports MIMO technology (that is, allows multiple antennas to send and receive multiple spatial streams simultaneously)
(3) Consider the application interface that dual-band WiFi modules can provide, which is also very important.
(4) According to the requirements of the application scenario to choose the dual-band WiFi module, not the higher the configuration, the better, the application is good, excess waste!
