ZigBee Features

Low power consumption

In the low power standby mode, the 2 sections 5 dry cells can support 1 node for 6~24 months, or even longer. This is a prominent advantage. Compare,

Bluetooth can work for several weeks, and WiFi can work for hours.

Based on low cost

Through a simplified protocol (not to Bluetooth 1/10), reduces the communication requirements of the controller, according to the forecast analysis, 8 to 8051 microcontroller estimates, the master node full function 32KB code, sub-function fewer nodes to 4KB code, and ZigBee patent fee-free agreement. The price of each chip is about $2.

Low rate

ZigBee operates at a rate of 20 to 250kbps, providing 250 Kbps (2.4GHz), 40kbps (915 MHz), and 20kbps (868 MHz) raw data throughput rates to meet the application requirements for low rate data transmission.

Based on lose distance

Transmission range generally between 10 ~ 100m, after the increase of transmission power, can also be increased to 1 ~ 3km. This refers to the distance between adjacent nodes. If the relay is routed and communicated between nodes, the transmission distance can be further.

Just short duration

ZigBee’s response rate is faster, generally transferred from sleep to work, just 15ms, node connection into the network only 30ms, further save the electricity. By comparison, Bluetooth takes 3 to 10s, and WiFi requires 3 s.

High capacity

ZigBee can use stellate patch and mesh network structure, which is composed of a main node management sub-node, at most one master node can manage 254 nodes; at the same time, the master node is also composed of a layer of network node management, most can be composed of 65000 node network.

High security

ZigBee provides a three-level security model, including security settings, the use of an access control list (Access Control, List, ACL) to prevent illegal access to data, and using the advanced encryption standard (AES 128) of the symmetric encryption, to determine its security attributes flexibly.

 No needing licensed band

Use the industrial science medical (ISM) frequency band, 915MHz (USA), 868MHz (Europe), and 2. 4GHz (global),.

Since the three frequency bands have different physical layers, their respective channel bandwidths are different, such as 0.6MHz, 2MHz, and 5MHz. There are 1, 10, and 16 channels, respectively.
The spread spectrum and modulation modes of the three frequency bands are also different.

Spread spectrum (DSSS) uses direct sequence spread spectrum (DSSS), but the bit to chip conversion is quite different. Modulation methods are used phase modulation technology, but the 868MHz and 915MHz frequency bands are BPSK, and the 2.4GHz frequency band adopts OQPSK.

In the case of transmit power of 0dBm, Bluetooth usually has a range of 10 meters. And ZigBee in the interior can usually reach 30-50 meters of the role of distance, in the outdoor open area can even reach 400 meters (TI CC2530 without power amplification).

Therefore, it can be classified as a low rate short-distance wireless communication technology.

 

The solution design is based on the IEEE 802.15.4 wireless protocol.

Zigbee is a reliable, low-power, and interoperable protocol that shows high immunity in noisy RF environments. Zigbee PRO certification ensures the interoperability of smart objects, enabling IoT devices from different vendors to work together. Interoperability between products of different vendors.

Highfive Electronics is the Leading electronic ODM company for solutions.

IEEE 802.15.4 is a technical standard managed by the IEEE 802.15 working group. It defines the physical layer and provides a common standard for the MAC layer, which serves as the basis for multiple protocols including Zigbee.

Our solution provides free and comprehensive technical support for 2.4GHz wireless technology, including Zigbee PRO software stack.

The Zigbee 3.0 cluster is very suitable for home or building automation applications, medical equipment data collection, and other applications for low power consumption and low bandwidth requirements. These applications are designed for small wireless projects. Can customize the products and projects you need for you.

Using Zigbee PRO and Zigbee 3.0 together can make you fast and efficient and continuously reduce product development costs.

The solution is based on the market-proven Zigbee PRO 2017 protocol stack. In order to further simplify development, we can help customers quickly build device applications.

Different functions that exactly match the device configuration can be provided according to specific requirements. FFD (full function device) and RFD (reduced function device) configurations are available and provide greater freedom of device size, including OTA function.

With green power support, our solution is also suitable for battery-powered or even battery-free applications and projects.

Our smart solutions also cover other applications for energy and water monitoring.
