Which communications equipment is commonly used for local area networking in tactical operations?

The correct answer highlights the use of Power-over-Ethernet (PoE) devices for local area networking in tactical operations. PoE technology allows both data transmission and electrical power to be delivered over standard Ethernet cables. This capability is especially beneficial in tactical environments where power sources may be limited, and it facilitates the setup of networking devices such as access points, cameras, and VoIP phones without the need for separate power cables.

Using PoE also reduces the complexity of installation and increases flexibility, allowing for quick deployment and reconfiguration of network setups. In tactical operations, speed and adaptability are crucial, and having a streamlined system that requires fewer components to deliver both power and data is advantageous.

While other options like satellite transceivers, cellular routers, and fiber-optic cables have important roles in communications, they serve different purposes. Satellite transceivers are primarily used for long-range communication rather than local area networking. Cellular routers connect to cellular networks for internet access but are not as efficient for in-building or local area connections compared to PoE technology. Fiber-optic cables, though providing high-speed data transmission, require specialized installation and may not offer the power delivery feature that is essential in tactical scenarios. Thus, PoE devices are more suited for local
