Government operations, particularly military radar operations. Certain sub-bands of the U-NII band are currently used primarily by U.S. One solution to such overcrowding is to use a prior art frequency translator to translate the RF carrier signal between the 2.4 GHz ISM band and a second unlicensed band, such as, for example, the Unlicensed National Information Infrastructure (U-NII) band, thereby avoiding the congestion and interference. Thus, fixed wireless local area networks (LANs), for example, involving digitally encoded data modulated onto an RF carrier signal in the 2.4 GHz ISM band, suffer increasing interference from a variety of devices, such as, for example, microwave ovens, cordless telephones, and Bluetooth apparatuses. This is exacerbated by the fact that only three of the twelve DSSS channels assigned in the 2.4 GHz ISM band are usable simultaneously at 11 Mbps within a 1000 foot radius using an omni-directional antenna. As a result, the 900 MHz and 2.4 GHz unlicensed frequencies are becoming increasingly overcrowded and congested. Developments in a number of different digital technologies have greatly increased the need to transfer large amounts of data from one network or system to another. More particularly, the present invention concerns a frequency transverter and method for enabling bi-frequency dual-directional transfer of digitally encoded data on an RF carrier by translating between a first frequency band, such as the 2.4 GHz ISM band, and a second frequency band, such as the 5.0 GHz-6.0 GHz U-NII band.
