Under the wave of the Internet of Things, which communication method should be used to connect the hardware to the cloud? This is a headache for all smart hardware entrepreneurs and even customers. As the leader of LED digital smart power supply, I will boldly introduce the difference between the current three forms of ZigBee, Wi-Fi, and BLE.
1. Lifx. Wi-Fi
Wi-Fi, I believe we all know it well. It is the built-in network protocol on our mobile phones. The Lifx smart lighting products that use the Wi-Fi protocol are also smart lighting products that can connect directly to the Internet. Of course , Can also be accessed directly from the phone.
The advantage of Wi-Fi is that it is relatively fast, can directly access the Internet without a bridge, and can communicate with mobile phones seamlessly. The main disadvantage is that the package size of the Wi-Fi chip is relatively large, and the function The power consumption is relatively high. The standby power of Lifx may be as high as 1W, while the typical standby power consumption of BLE and ZigBee is within 0.1W.
The number of nodes of the WiFi router (typical value is dozens of nodes).
The other one is the security issue that we are concerned about now. Think about the products in the smart home if they are connected by Wi-Fi. If one day is hacked, it would be a bit scary.
2. hue. ZigBee
Firstly explain the origin of the name ZigBee. After the bees find the flowers, they will use a special body language to inform the fire partner of the newly discovered food source location and other information. This body language is the ZigZag dance, which is a simple way of conveying information between bees. This means that ZigBee is the name of a new generation of wireless communication technology.
The ZLL (ZigBee Light Link) used by Philips hue is an extension set developed on the ZigBee protocol. This protocol is led by Philips. It is expected that the intelligent connection of lights can be completed more simply. The first product hue can be said to be lighting A new era has opened up in history.
ZigBee is a low-speed, low-power wireless control protocol. It can automatically form a network. Each node of the network can transmit data by virtue of its power. A rendezvous node is needed in the network to manage the entire network. This extra guy is
The Bridge thing in the Starter package of hue has no additional use in itself, but it can integrate other lights into a network and connect it to the Internet in parallel.
The harm is to increase the cost and increase the complexity of the device, and it cannot be directly connected by our mobile phone. It must be switched. The advantage is that the ZigBee lamp can be connected to the Internet through the Bridge, and then it has more The remote access capability (which also means danger), hue is a product based on this technology, and each subnet supports approximately 50 nodes.
ZigBee products usually have lower power consumption, and the cost is also lower than that of Wi-Fi products, similar to low-power Bluetooth products. Another is the price of hue that is so expensive that even Lao Mei complained. The starter set is 1699 yuan, including three light bulbs + a gateway. Well, it's really a local tyrant.
3. yeelight blue. BLE
BLE (Bluetooth Low Energy Technology) is the latest new product focusing on low power consumption (button battery can continue to stand by for more than half a year), fast connection (only 1-3ms), and long-distance communication (up to 50m or more). A generation of short-range wireless communication specifications, with special attention and optimization of the data exchange of small data packets;
can be said to be a communication method tailored for the IOT (Interoperability Test) era of different vendors of the Internet of Things. The flaw is that it cannot be supported by old smart phones (only iPhone 4S future Apple phones and Android 4.3 future Android phones are supported. It’s easy for my friends to change their phones, now that the phones are so cheap, you say no)
But with the passage of time, most modern smart phones can now be supported, and are now rapidly becoming the standard communication protocol for a new generation of smart hardware.
