This wireless technology is sometimes referred to as line-of-sight communication because the light waves can only travel in a straight line.

At what frequencies is line-of-sight transmission the only method of propagation?

What does the term "non-line-of-sight" (NLOS) communication mean in the context of WiMAX?Transmission where the transmitter and receiver are directly visible to each otherTransmission that requires satellite assistanceTransmission where obstacles block the direct path between transmitter and receiverTransmission that relies on optical signals

Like WiFi, cellular networks use what to transmit data? LAN Connections O Cables Radio Waves Local Loops

Highlight Instance of Guided Transmission Mediaa.Communication via satellites in geostationary or low Earth orbit. Used for television broadcasting, long-distance communication, and global positioning systems (GPS).b.Fiber Optic Cable:Uses thin strands of glass or plastic to transmit data using light signals. Offers high bandwidth and is immune to electromagneticc.Similar to fiber optic cable but without the protective covering. Used in short-distance, high-speed data connections, such as within data centers.d.NFC (Near Field Communication): Short-range wireless communication technology used for contactless payments, data exchange between devices in close proximity.e.Coaxial Cable: Consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer.f.Similar to fiber optic cable but without the protective covering. Used in short-distance, high-speed data connections, such as within data centersg.Bluetooth:Short-range wireless technology used for connecting devices such as smartphones, laptops, and peripheralsh.Uses infrared light for short-range communication. Often used in remote controls, some short-range data transfer applications, and IrDA (Infrared Data Association) communicationi. Electromagnetic waves used for wireless communication. Commonly used in radio and television broadcasting, as well as Wi-Fi networks.j.Twisted Pair Cable: Consists of pairs of insulated copper wires twisted together. Commonly used in telephone lines and local area networks (LANs).k.Electromagnetic waves with higher frequencies than radio waves. Used for point-to-point communication over long distances, such as in microwave communication towers.
