Analysis of three communication modes of intelligent lighting

Introduction: in the current WIFI, ZigBee, low-power Bluetooth and other mainstream wireless communication under the premise of how we choose?

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 contend for we know that the WIFI technology as the development 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 that hue as an example to describe, 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 connecting 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. However, taking into account the Bridge can bring more remote access capabilities, coupled with the inherent characteristics of low power consumption, tall on the company, you 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.

What is BLE, launched on 2009, this technology has become a major manufacturer of "guest of honor", mobile phone, wireless networks and other manufacturers will be the focus on low power consumption, fast connection, long distance communication of the new generation wireless communication standards integrated into their own products. Intelligent lighting manufacturers can not help but vulgar, rapid attention and integrate this technology into their products. Another advantage of BLE is that the new mobile phones on the market are equipped with the technology to facilitate the user's connection control of lighting equipment. In addition, the support of semiconductor manufacturers to BLE is also a starting point for developers to choose this technology. It is worth mentioning that in the Bluetooth 4.1 protocol, BLE products have the characteristics of the ZigBee network, which are in the traditional ZigBee product range of impact. Coupled with Apple's release of the iBeacons standard, this non connectivity communication greatly increases the likelihood of BLE control products and imagination. If the BLE has a point defect in want of perfection, in addition to plan other than price, there is the old mobile phone, because the collocation is not Bluetooth 4 chip, which makes the control of intelligent lighting equipment trouble. But do you think this is a limitation when it comes to changing the speed of modern people?

Wireless lighting direction to 2020, use the world connected to the Internet and wireless lighting and lighting from above 2 million 400 thousand this year is expected to increase to 100 million, and the development trend of network to these devices cannot do without the support of wireless, this trend will inevitably lead to communication technology dispute. What is the traditional WIFI or more advantages of talent shows itself, ZigBee xianbatouchou, or is the bright younger generation BLE counter attack? Which would you choose?
