What kind of communication mode of intelligent lighting?

In recent years, the Internet of things East, the concept of LED intelligent lighting more hot speculation. In addition to the low power consumption, environmental protection, dimming and color and other aspects of the control of the LED, the manufacturer of another key to intelligent lighting - wireless control is also continuing concern. Therefore, how to build a smart home to meet the basic needs of low-power, efficient wireless LED lighting system is the top priority. In the current WIFI, ZigBee, low-power Bluetooth wireless communication, such as the mainstream of the premise, how should we choose?

WIFI, ZigBee and BLE dispute

We know that WIFI technology R & D because of low threshold, low cost, and has a relatively fast speed, coupled with the bridge without direct access to the Internet and mobile phone seamless communication advantage, make it become the choice of many start-ups, the biggest advantage of this is reflected in the WIFI.

But WIFI has shortcomings is obviously, in addition to the WIFI chip size is too large, the power consumption is too high, there is no difference of experience bring its stability, the crucial point is that WIFI will bring security problems, which is the key to believe that the purchase is an important consideration, so when manufacturing products, need to weigh the pros and cons selection of WIFI products.

In addition, the characteristics of limited to the WIFI itself, the number of node access limit access modes mainly restricted to the WIFI router (typically tens of nodes), the user that many of the lighting equipment, and often ignore the WIFI products.

Another major wireless connection is ZigBee, the low power wireless control protocol, since the birth of popular users and manufacturers are welcome, ZigBee ad hoc network, and each node of the network can be leveraging data transmission, so the network requires a centralized node to manage the whole network, this also means that a ZigBee network router must have a similar role, conversion to complete the ZigBee Protocol Internet protocol.

On the router, in order to show us, PHILPS hue as an example, this extra guy is hue Starter package called Bridge, which itself has no additional use, but can be integrated with other lamps for a network, and connect to the internet.

From the above description, the most obvious disadvantage of ZigBee is the increase in cost and complexity of the installation, in addition to the need to connect with the phone. But taking into account the Bridge can bring more remote access capabilities, coupled with the inherent characteristics of low power consumption, such as PHILPS and other tall companies, should choose this program.

So for WIFI and ZigBee, are Sometimes an inch may prove long., everyone has his own advantages. Specific choice depends on the balance of the manufacturers and the user's choice.
