Exploit differences in technologies and frequency bands.

发掘各种技术和频带之间的差别。

The root cause for interoperability remains the same--multiple users in different frequency bands using different waveforms.

同样，这也是使用不同波形、不同频率的多个用户不能保持互操作性的根本原因。

Reference data for RCS scales, radio-frequency bands, engagement geometries, and representative threat systems are summarised in Annex a.

The technology uses gaps in radio spectrum, called 'white spaces', which exist in between frequency bands.

The superconductor's lack of resistance allows the firm to build filters that can chop a signal into much narrower frequency bands than a traditional filter.

For example, 3G cell phones require multiple power amps (compared to one in each 2G phone) to support 2G and 3G air interface standards across multiple frequency bands.
