Deep Dive: E2C09
The correct answer is C: A wireless router running custom firmware. What type of equipment is commonly used to implement an amateur radio mesh network is a wireless router running custom firmware. Mesh networks use modified routers with custom firmware. For amateur radio operators, this is important for mesh network operation. Understanding this helps when setting up mesh networks.
Why Other Answers Are Wrong
Option A: Incorrect. 2-meter VHF transceiver with 1,200-baud modem isn't used - mesh networks use wireless routers, not VHF transceivers. VHF transceiver isn't used. Option B: Incorrect. Computer running EchoLink isn't used - mesh networks use wireless routers, not EchoLink. EchoLink isn't used. Option D: Incorrect. 440 MHz transceiver with 9,600-baud modem isn't used - mesh networks use wireless routers, not UHF transceivers. UHF transceiver isn't used.
Exam Tip
Mesh network equipment = wireless router running custom firmware. Think 'M'esh 'N'etwork = 'M'odified 'R'outer. Mesh networks use modified routers with custom firmware. Not VHF transceiver, not EchoLink, not UHF transceiver - just wireless router with custom firmware.
Memory Aid
Mesh network equipment = wireless router running custom firmware. Think 'M'esh 'N'etwork = 'M'odified 'R'outer. Mesh networks use modified routers with custom firmware. Important for mesh network operation.
Real-World Example
An amateur radio mesh network: It's commonly implemented using a wireless router running custom firmware (e.g., AREDN firmware). The router is modified to work as a mesh network node. This is the equipment - wireless routers with custom firmware are used for mesh networks.
