1Length of stationary object
If relay terminals with simplified protocol stacks are deployed to extend communication range, then communication coverage is improved, but device complexity increases
Solution Approach 1:
The system segments the network into different functional layers: relay terminals with simplified protocol stacks handle local communication and data forwarding, while the core network handles complex routing and management. This segmentation allows extended communication range without requiring every device to have full protocol stack complexity.
Solution Approach 2:
Relay terminals act as intermediaries between IoT devices and the core network. These relays use simplified protocol stacks (such as LwM2M or CoAP) to communicate with IoT devices, then forward data through standard IP-based networks, thereby extending communication range while avoiding the need for every device to implement complex protocols.
2Ease of repair
If more relay terminals are deployed to reduce maintenance needs, then maintenance costs decrease, but deployment complexity increases
Solution Approach 1:
The relay terminal system implements self-service through automated discovery, configuration, and data forwarding mechanisms. Relay terminals automatically register with the core network, establish communication paths, and forward data without manual intervention, reducing maintenance needs while keeping deployment relatively simple through standardized protocols.
Solution Approach 2:
The relay terminals are designed with multi-functionality to handle various communication protocols and data types through a unified architecture. This universality allows the same relay device to serve multiple purposes (data forwarding, protocol translation, local processing) reducing the number of devices needed and simplifying deployment while maintaining low maintenance requirements.
