Which type of fixed wireless network offers longer ranges and higher speeds by using high-frequency signals?

The choice of a microwave-based fixed wireless network is correct because this technology utilizes high-frequency signals that can effectively transmit data over long distances. Microwave communication operates at frequencies typically between 1 GHz and 300 GHz, which allows for broader bandwidth and faster data rates compared to other types of fixed wireless networks.

Microwave-based systems are adept at providing higher speeds due to their capacity to carry large amounts of data, making them ideal for applications requiring robust and reliable connections over considerable distances, often in line-of-sight arrangements. This capability is essential for networks that need to deliver substantial data throughput between fixed points, such as in telecommunications and internet backhaul scenarios.

In contrast to other options, while Wi-Fi operates in lower frequency bands and excels in short-range wireless connectivity, it does not match the longer-range capabilities of microwave networks. Cellular networks, although they can provide widespread coverage, typically rely on a combination of different technologies and may not achieve the same maximum speeds as dedicated microwave systems. Lastly, while satellite networks can also cover large areas, they often suffer from latency issues and are limited by the physical constraints of satellite technology, making them less effective for high-speed applications compared to microwave-based solutions.
