The wide band radio transmission may be implemented in two parallel ways: to design a new system with larger bandwidth; to construct a cooperative system based on existing systems.
大带宽无线传输有两个实现途径，一是设计频带更宽的单一系统，一是进行不同系统间的协同设计。
In one exemplary embodiment, the multi-band antenna system 100 is tuned to operate within two general radio frequency ranges which are generally referred to as a low band and a high band.
在一个例示的实施例中，多波段天线系统100被调谐为在两个通常的射频范围内操作，这两个通常的射频范围通常称作低波段及高波段。
