HXI Radio Brochure

GigaLink LightSpeed millimeter wave point-to-point digital radios first debuted in 1995 under an experimental deployment with NTT in Tokyo. As Harmonix (our original name), we were instrumental in securing the FCC allocation of the 60 GHz spectrum in the USA, and we were the first FCC Part 15.255-certified MMW system operating in the 57 to 64 GHz band (V-Band). Since that time, HXI has consistently set the mark for reliability, capacity, and low cost of ownership for V-Band and E-band (70/80 GHz) digital radios. This tradition continues with our newest GigaLink LightSpeed millimeter wave radios, which are available to satisfy most regional allocation rules.

Radio Capabilities/Features

  • 60, 67 and 70/80 GHz radios with industry standard features.

Custom-Designed Analog Radio Links

HXI routinely addresses requirements for customized versions of these radios, including analog links, custom antenna configurations, alternate frequency bands, HDTV usage, etc. Among our customers for custom versions are the Air Force and the Department of Energy.

HXI has developed a number of custom-designed analog radio links for a variety of applications. Backhaul of collected data that needs to stay in analog format is a common usage. Perhaps the most unique application of our radios is the usage by Brookhaven National Labs on Long Island, where two of our analog links are used for particle beam path correction in their RHIC facility. In this case, extremely low latency coupled with wide frequency bandwidth and high dynamic range was required to complete a feedback loop for the control of the beam.

Stochastic Cooling in RHIC
cutting the chord enables higher loop bandwidth.
