What advantage does lower frequency have in radio communications?

The advantage of lower frequency in radio communications is that it requires fewer tower sites for effective signal coverage. Lower frequency waves have longer wavelengths, which enables them to travel further distances with less attenuation. This means that a single tower transmitting at a lower frequency can cover a larger geographic area compared to higher frequency signals. Consequently, this characteristic reduces the need for multiple towers to achieve the same coverage, leading to cost savings and simpler infrastructure management.

In contrast, while lower frequencies might also provide advantages like better penetration through obstacles, greater signal strength, and potentially lower power consumption, the primary and most direct benefit in terms of network infrastructure is the ability to cover larger areas with fewer tower installations. This reduces operational costs for service providers while maintaining effective communication capabilities.
