Compared Wi-Fine and Wi-Sun


 We compared WiFine and WiSun as following:


Wi-Fine Wi-SUN
Definition a new type of RF communication -- WiFine.
Wireless Free Intelligent Network
Home area network
Field area network
Wi-SUN Alliance bring Smart Ubiquitous Networks to service providers by enabling interoperable, multi-service & secure wireless mesh networks.
Network scale no theoretical upper limitover 10,000 nodes 1,000 nodes
Network construction time No networking time,
No route switching time.
(Instantaneous networking
Instantaneous route switching)
Depending on the network size , a few minutes to an hour. Level 7 network construction takes more than 30 minutes, and level 255 requires a lot of time
Routing level 255 levels More than ten levels of theory, 7 ~ 8 levels of actual
Sleep mode A variety of sleep, all nodes can sleep more, current <4mA when receiving, 0.3μA when sleeping There is no sleep at present, and the end node can sleep in the future. Current 8mA when receiving, 2μA during sleep
Mobile transmission Move arbitrarily, data continuously spread during the movement Unmovable
Network topology Multiple: two-way communication between nodes; two-way communication between nodes and gateways Only nodes and gateways
Whole Net Collection Collect thousands of nodes data within seconds, 100% meter reading on the whole network Difficult to support
Safety Each node has an immutable 6-byte customer ID and 6-byte global unique number UUID; each node is configured with a 3-byte network ID and 128 wireless channel codes. For dynamic encryption, the secret key uses a combination of the above three IDs and wireless channel coding. Use CRC-32 for message verification RPL routing protocol
IEEE 802.15.4G
IETF IPV6
Power Efficiency drawing less than 3μA when resting, around 4mA when listening drawing less than 2μA when resting, around 8mA when listening
OTA All nodes in the whole network can perform OTA at the same time.
Achieve all nodes OTA in seconds
30 nodes OTA takes more than ten minutes, if the number increases, it cannot be realized
Economy Highly cost-effective Proprietary chip, certified, currently very expensive
