Strong anti-interference ability: ZigBee transceiver module uses 2.4G direct-sequence spread spectrum technology, which has better anti-interference ability than general FSK, ASK and frequency hopping data transmission stations.
Good confidentiality: ZigBee provides data integrity check and authentication functions, ZIGBEE Module the encryption algorithm adopts the general AES-128, and the 128-bit password guarantees the confidentiality of ZigBee signal transmission.
Fast transmission speed: ZigBee mostly uses short frames to transmit data, so the transmission speed is fast and the real-time performance is strong.
Strong scalability: ZigBee is easy to network and has strong self-recovery ability. Therefore, it is easy to expand in smart homes and add new devices.
The advantages of zigbee technology looks beautiful
However, we must realize that after many functions of ZigBee are implemented in the application scenarios of smart homes, they become beautiful advantages:
Is the cost of the zigbee module really low?
At present, TI's CC2430, CC2530 and Freescale's MC1319X and MC1322X series, which have relatively large shipments of ZIGBEE chips, cost about 2 to 3 US dollars. Considering other peripheral devices and related 2.4G RF devices, the BOM cost is difficult to be low At $10, serial to ethernet adaptor the cost is quite embarrassing for smart home devices that are cost-sensitive and require a large number of nodes.
