frequency band

基本解釋

The RF-7800V provides continuous coverage in the 30 to 108 MHZ frequency band at up to 50 watts of power.
還可在50w功率下提供30-108MHz的持續(xù)性頻率覆蓋。

Bluetooth is a universal radio interface in the 2.45GHz frequency band that enables portable electronic devices to connect and communicate wirelessly via short-range, ad hoc networks.
藍牙是一個頻率爲2.45GHz的通用無線電通信接口，它通過一個特殊的網(wǎng)絡(luò)可以在各種便攜設(shè)備之間建立起無線連接竝進行短程通信。

Between them, Sprint and Nextel own nearly all the spectrum licences for the unused 2.5GHz frequency band.
