Question
Which is true of mesh network microwave nodes?
Answer Options
- A) Having more nodes increases signal strengths
- B) If one node fails, a packet may still reach its target station via an alternate node
- C) Links between two nodes in a network may have different frequencies and bandwidths
- D) More nodes reduce overall microwave out of band interference
Correct Answer: B
Explanation
Mesh networks, such as AREDN, are designed to be resilient and self-healing, a critical feature for emergency data communication. In a mesh network, each radio acts as an independent routing node.
The core strength of this design is that if one node fails, a packet may still reach its target station via an alternate node (or path). This redundancy means the network can adapt to failures and physical damage (like downed infrastructure) without losing connectivity between the remaining nodes, ensuring high reliability during a disaster.
