The new rule for the future is going to be,

"Anything that can be connected, will be connected."

So what is the Internet of things ?

Simply put this is the concept of basically connecting any device with an on and off switch to the Internet (and/or to each other). This includes everything from cell phones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of.This also applies to components of machines, for example a jet engine of an airplane or the drill of an oil rig. As I mentioned, if it has an on and off switch then chances are it can be a part of the IoT. The analyst firm gartner says that by 2020 there will be over 26 billion connected devices...that's a lot of connections (some even estimate this number to be much higher, over 100 billion). The IoT is a giant network of connected "things" (which also includes people). The relationship will be between people-people, people-things, and things-things.

Wifi module is the entrance to smart home ?

When it comes to communication solution of smart home,there are four solutions including bluetooth, zigbee, wifi and 433 wireless.Due to communication distance of bluetooth and inaccurate feedback of 433 wireless communication, these solutions have been used rarely.

Actually, zigbee solution has been widely applied in smart home products in the earliest time. Even now,there are many zigbee products.Actually wifi has a congenital advantage;wifi can directly connect to the Internet. And now every family has a wifi router.But because wifi cost is relatively higher, and power consumption and volume of wifi hinders its development.

If using zigbee solution, even if you only buy one smart device, you must buy an additional zigbee network equipment.what is worse is that zigbee communication is less stable than wifi communication.With the increase of wifi attention,cost reduction of semiconductor and appearance of low power small size solution,the advantage of the wifi becomes more and more obvious

After the wifi solution is determined, everyone begins to look for the entrance to smart home.The first is intelligent router and then the smart socket,and now the wifi module.

Wi-Fi Technology from LAN to IOT

WIFI technology has always been positioned in networking applications of enterprise LAN ,due to restrictions of roaming, switching, security, interference and transmission rate.And it seems that the main goal of wifi application is to replace enterprise cable network. However, as emerging technologies like IOT, wifi city and digital family triggers a new round of science and technology revolution,wifi technology is stepping out of enterprise Intranet.
