zigbee gateway vs wifi router

Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this protocol is a short-range, low-power wireless communication technology. The name comes from the bee's eight dance, because the bee (bee) is to fly and "buzz" (zig) shake wings "dance" to pass the pollen location information with their companions, that is to say, the bee relies on such a way to form a group in the In other words, bees rely on this way to form a communication network in the colony. It is characterized by proximity, low complexity, self-organization, low power consumption, low data rate, and low cost. It is mainly suitable for use in the field of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is an inexpensive, low-power near-distance wireless networking communication technology.

If your computer or cell phone is installed with a zigbee module, it can transmit data to and from the zigbee gateway, but the zigbee transmission data rate is relatively low, only 250Kb/S in the 2.4GHz band, and this is only the link rate, in addition to the consumption of channel competition and retransmission, the real rate of utilization may be less than 100Kb/S. The zigbee transmission data rate may be less than 100Kb/S. If the zigbee module is installed with a zigbee module, it can transmit data to the gateway, which is the lowest rate of transmission. After channel contention and retransmission, the real rate that can be used by the application is less than 100Kb/s, and the rest of the rate may be divided by multiple neighboring nodes and multiple applications on the same node, so even if you can surf the Internet, it is still laggy, and even less suitable for watching video and other things.

So now zigbee technology is mostly used in sensing and control, mainly in the following areas:

Home and building networks: temperature control of air conditioning systems, automatic control of lighting, automatic control of curtains, gas metering control, remote control of household appliances, etc.

Industrial control: automated control of various monitors, sensors

Commercial: smart labels, etc.

Public **** places: smoke detectors, etc.

Agricultural control: collection of all kinds of soil information and climate information

Medical: emergency pagers and medical sensors for the elderly and mobility-impaired, etc.

Of course, we do not rule out the future zigbee gateway to add wifi, cable TV, network TV function integration, then in the future, the family only need a zigbee gateway can realize the smart home control, Internet access, watch TV and other functions.
