A.Wide coverage

B.Big Connection

C.low cost

D.Low power consumption

E.High bandwidth (correct answer)

A.After the interface of the registered direct-connected device is called, if the binding is not completed within the timeout range, the device registration will be invalid

B.When registering directly connected devices, nodeid recommends using the MAC address of the device

C.When registering directly connected devices, if timeout is set to 0, there is no timeout setting

D.Register directly connected device interface, not only can be used to register directly connected devices, but also can be used to register non-directly connected devices

A.Security

B.Ability open

C.Elastic scaling

D.Access irrelevant

A.The application layer provides rich data processing capabilities

B.The platform layer provides rich protocol adaptation capabilities

C.Downstream convergence and upstream backhaul at the network layer.

D.Perception layer provides rich sensing data collection capabilities

A.The small packet fast transmission mechanism controls the packet length sent by the wireless link in a small range

B.For each small packet base station, it will quickly feedback whether it is successfully received, if it fails, the terminal will retransmit; otherwise, continue to send

C.The small packet fast transmission mechanism controls the packet length to reduce the probability of interference during the data packet transmission process

D.Fast feedback of the reception result improves the uplink transmission efficiency.
