The mesh network is a wireless network architecture where multiple nodes are interconnected to provide extended coverage. Mesh networks are used in various applications, including industrial, commercial, and residential environments.

When monitoring a mesh network on a map, it's important to visualize the mesh link status between the nodes accurately. The mesh link status provides information about the quality of the link and can help identify potential problems.

The two mesh link options that can be shown as link labels on the map are:

A. SNR (Signal-to-Noise Ratio) - SNR is a measurement of the strength of the received signal compared to the background noise. It provides an indication of the link quality and the potential for data transmission errors. Higher SNR values indicate better link quality.

C. Data Rate - Data rate is the speed at which data is transmitted over the link. It's important to monitor the data rate as it provides an indication of the available bandwidth and the overall link capacity. Higher data rates indicate better link quality.

B, D, and E are not valid options for link labels in a mesh network map:

B. Packet error rate - Packet error rate is a measurement of the number of packets lost or corrupted during transmission. While it's an important metric for network performance monitoring, it's not commonly used as a link label on a mesh network map.

D. Backhaul channel - Backhaul channel is the frequency channel used to transmit data between mesh nodes and the main network. While it's important to monitor the backhaul channel, it's not commonly used as a link label on a mesh network map.

E. Hop counter - Hop counter is the number of intermediate nodes that data packets travel through to reach their destination. While it's an important metric for network performance monitoring, it's not commonly used as a link label on a mesh network map.

In summary, when monitoring a mesh network on a map, the two mesh link options that can be shown as link labels are SNR and Data Rate.
