What type of internet connection uses an antenna that requires a clear line-of-sight to the ISP's antenna?

Line-of-sight wireless connections utilize antennas that need a clear line-of-sight between the user’s antenna and the Internet Service Provider's (ISP) antenna. This type of connection is often utilized in rural or remote areas where traditional wired connections may not be available. The line-of-sight requirement means that any obstructions, such as buildings or trees, can disrupt the signal, which is essential for maintaining a stable and high-speed internet connection.

In contrast, DSL and cable connections rely on existing telephone or coaxial cable infrastructure and do not require direct line-of-sight. Satellite connections, while they do involve antennas, communicate with satellites in orbit rather than a ground-based antenna, making them unaffected by terrestrial line-of-sight issues. Thus, line-of-sight wireless stands out for its specific requirement of unobstructed view between the transmission points.
