At present,there is an irreversible global tendency that Wireless to replace the cable, which is specially obvious in smart home area. For smart home industry,different technologies are applied by different companies. The effects are absolutely different. Till now,we have two major technologies in smart home industry-WiFi and ZigBee. But who will lead the wireless technology in future house?
Let’s compare these two technologies from the following several aspects.
Firstly，these two wireless technology have different technological hurdles and costs on technology research and development.WiFi has a low technology stander and costs.It is not a difficult item for the ordinary company to develop.That is why we have so many WiFi products and company during the past ten years.On the contrary, lifecycle of system development and technology stander of ZigBee technology are much longer and higher than WiFi,which determines a situation that only some companies having strong strength can work on this technology.
Secondly,for the low technology stander and costs,WiFi is less secure than ZigBee.As you know,WiFi is easy to break and disturb.However,there is no case where people break through ZigBee technology at present.
Thirdly,ZigBee technology has a better energy conservation than WiFi technology.As a high energy consumption,WiFi cann’t be applied in some special products,such as smart lock, IR transmitter and detectors etc.On the other hand,a Section volts battery can supply power to ZigBee products for ten years in theory.
Finally,let us talk about the network capacity of these two technology.WiFi has a weak network system which only can serve 16 product on line.But ZigBee could support 65000 on line at the same time.For supporting more products in future house,ZigBee absolutely will be your best choice.
In conclusion,WiFi faces a series awkward problems in smart home area.At present,many specialists think that WiFi can be used in intelligent item for demonstration or some easy applications.But for a long term behavior and security,ZigBee technology has more advantages and application prospect.
