The 5.8GHz bands have much greater spectrum available. In this band there are 12 non-overlapping channels, each with 20MHz of bandwidth. The 5.8 GHz Frequency-Hopping Spread Spectrum technology operates on a different wavelength with much less traffic than the 2.4 GHz technology while maintaining the great security, incredible clarity and long range. This means significantly better performance as compared to the 2.4GHz band. The entire 2.4GHz band is 80MHz wide, which only allows three non-overlapping channels.
Have a wireless computer network, or thinking about getting one? 5.8 GHz technology will not interfere with wireless networks such as 802.11b or 802.11g WiFi. If high performance is an important requirement, then lean toward the 5.8GHz band.
