Which band is typically used for local communications in urban areas?

The UHF band is commonly used for local communications in urban areas due to its favorable propagation characteristics and ability to support a variety of communication needs, including voice and data transmission. Several factors contribute to this preference:

1. Frequency Range: The UHF band operates between 300 MHz and 3 GHz. This range allows for effective line-of-sight communications, which is advantageous in densely populated urban environments where tall buildings can obstruct signals.

2. Propagation: UHF signals can penetrate buildings better than lower frequency signals, making them suitable for local communications like two-way radios, television broadcasts, and wireless communications.

3. Bandwidth: The UHF band provides more bandwidth compared to lower frequency bands, which enables higher data rates and more channels for simultaneous communications. This characteristic is especially important in urban areas where many users need to communicate at the same time.

4. Applications: UHF is widely used in commercial services, emergency communications, and public safety communications. It is also the frequency range for many consumer devices like walkie-talkies and mobile communications, making it the go-to choice for local communication networks in cities.

While other bands have their own functions, they do not match the UHF band’s suitability for local
